A NEW SYSTEM ON CHIP RECONFIGURABLE GATEWAY ARCHITECTURE FOR VOICE OVER INTER...csandit
The aim of this paper is to present a new System on Chip (SoC) reconfigurable gateway
architecture for Voice over Internet Telephony (VOIP). Our motivation behind this work is
justified by the following arguments: most of VOIP solutions proposed in the market are based
on the use of a general purpose processor and a DSP circuit. In these solutions, the use of the
serial multiply accumulate circuit is very limiting for the signal processing. Also, in embedded
VOIP based DSP applications, the DSP works without MMU (memory management unit). This
is a serious limitation because VOIP solutions are multi-task based. In order to overcome these
problems, we propose a new VOIP gateway architecture built around the OpenRisc-1200-V3
processor. This last one integrates a DSP circuit as well as a MMU. The hardware architecture
is mapped into the VIRTEX-5 FPGA device. We propose a design methodology based on the
design for reuse and design with reuse concepts. We demonstrate that the proposed SoC
architecture is reconfigurable, scalable and the final RTL code can be reused for any FPGA or
ASIC technology. Performances measures, in the VIRTEX-5 FPGA device family, show that the
SOC-gateway architecture occupies 52% of the FPGA in term of slice LUT, 42% of IOBs, 60%
of bloc memory, 8% of integrated DSP, 16% of PLL and the total power is estimated at
4.3Watts.

This document discusses the priorities, needs, and views of IT organizations regarding their networks and infrastructure. It contains the results of surveys that find:
- Supporting business initiatives like mobility, data analytics, and cloud computing are top priorities for networks. Respondents want networks that are secure, high-performing, cost-effective and easy to manage.
- Increasing data storage needs are driven by business growth, more data per activity, and increased regulatory requirements.
- Cloud resources, data center consolidation, big data infrastructure, and video streaming will significantly impact networks over the next year as organizations pursue digital transformation.
- Characteristics like control, flexibility, reliability and cost management are important for networks to
It's common business policy for organizations of a certain size to have two data centers as part of a disaster recovery or business continuity plan. However, most enterprise - applications are not designed for or intended to use systems in two different locations.
Enter the notion of a data center interconnect, which extends an Ethernet network between two physically separate data centers. While the idea is simple, Ethernet wasn't designed to run across a wide area network. Thus, a DCI implementation requires a variety of technological fixes to work around Ethernet's limitations.
This report outlines the issues that complicate DCIs, such as loops that can bring down networks and traffic trombones that eat up bandwidth. It also examines the variety of options companies have to connect two or more data centers, including dark fiber, MPLS services and MLAG, as well as vendor specific options such as Cisco OTV and HP EVI. The report looks at the pros and cons of each option.
Dynamic Performance Acceleration - Reducing the Browser BottleneckXO Communications
This document describes Dynamic Performance Acceleration technology from XO Communications. It aims to optimize websites to reduce time-to-action, the amount of time until a user can interact with a page. It does this through techniques like prioritizing above-the-fold content, image combining, and script optimization. Dynamic Performance Acceleration analyzes pages and rewrites elements to accelerate loading without requiring changes from website owners. It provides these services through a global cloud platform with no hardware required.
Because email and messaging capabilities are so critical, they have in some respects become like a utility: like electricity, for example, email is so critical to the operation of any organization that it no longer provides any substantive competitive differentiation between companies. Like other utilities, then, the goal is to a) ensure that service remains available as close to 100% of the time as possible while b) simultaneously being provided as inexpensively as possible. For many organizations, managing email internally is a thing of the past, just like producing one's own electricity is a concept of the past.
A growing number of organizations are finding that the way to accomplish this through the use of Microsoft Exchange as a hosted service, a model in which a remote third party provider manages all backend services for a flat monthly per user fee. The advantages of this approach for organizations that want to realize the benefits of Exchange are that uptime of the Exchange infrastructure can be very high and the cost of managing Exchange can be reduced significantly - typically more than 50% compared to on-premises management. Further, the use of a hosted Exchange service allows an in-house IT staff to be deployed to other projects that will provide more value to the organization as a whole.
This white paper discusses the benefits of the hosted model for managing Exchange. It also lays out the detailed costs of managing a hosted versus an on-premise Exchange environment.

This document discusses the ROI and business value of application performance management (APM) solutions. It provides 10 scenarios where APM can provide quantifiable benefits, including:
1) Improving production and preserving revenue by reducing downtime of critical applications. An example shows a retail chain saving $52k per outage by reducing credit card outage duration by 40%.
2) Optimizing bandwidth expenditures by right-sizing bandwidth needs based on real network usage data. An example shows a company saving $99k annually by avoiding over-provisioning bandwidth for a VoIP rollout.
3) Eliminating redundant tools and equipment by replacing needs for devices like protocol analyzers and CSU/DSUs, saving on equipment costs.
The benefits of MPLS IP VPN networks are already being realized by many enterprises. In addition to maximizing performance while minimizing costs, MPLS VPNs offer the ability to prioritize applications such as VoIP by class of service (CoS), create and improve disaster recovery infrastructures, utilize a fully meshed infrastructure that replaces outdated hub and spoke architecture, and reduce complexity to simplify network management in an increasingly complex landscape.
When considering a migration to MPLS VPN, there are several key considerations that can significantly impact the process of planning, implementing and managing the network, as MPLS has some unique requirements and tasks associated with managing and administering the network. This white paper will explore some of those considerations and discuss how they can be addressed.
A Business Guide to MPLS IP VPN Migration: Five Critical FactorsXO Communications
Multi-Protocol Label Switching Internet Protocol Virtual Private Network, or MPLS IP VPN, refers to a VPN service enabled over a trusted provider’s private MPLS core backbone. It delivers the flexibility of an IP service with the essential service quality, performance, and security previously available only with legacy technologies. Other benefits include cost-effective security, any-to-any connectivity, Quality of Service, scalable bandwidth, and a platform for convergence.
Intro to Voice over Internet Protocol: What does VoIP Mean for My Business?XO Communications
Savatar, a strategy and technology consulting firm, and XO Communications,
a leading provider of telecommunications services for businesses, explain
Voice over Internet Protocol (VoIP) from the perspective of small and medium-
sized business (SMB) owners, specifically SMBs who are seriously considering
moving to VoIP, but are unsure what approach is right for them. This
paper presents key findings of a Savatar survey in which 500 SMB owners
and decision makers were asked how they thought a VoIP system would compare
to their current phone system in four areas: cost, system management,
migration to a new system, and feature availability. Key benefits of VoIP for
business include reliability and efficiency, cost savings, and convenience.
Avoid Three Common Pitfalls With VoIP Readiness AssessmentsXO Communications
The document discusses common pitfalls that enterprises face when conducting voice over IP (VoIP) readiness assessments. It identifies three main pitfalls: 1) relying on a single snapshot assessment that does not account for network changes over time, 2) believing that synthetic VoIP calls alone are sufficient to test readiness without considering impacts to other traffic, and 3) focusing solely on the initial assessment and not planning for ongoing monitoring and management after VoIP deployment. It recommends best practices for VoIP assessments that involve continuous monitoring, adding real VoIP traffic to assessments, and managing converged voice and data networks after deployment.
This paper outlines five critical factors for successful migration to MultiProtocol
Label Switching (MPLS) Internet Protocol (IP) Virtual Private Networks
(VPNs). Written for business executives and IT decision makers, the paper
discusses the current status of MPLS IP VPN adoption for the medium-to-large
business (5 to 50 locations), especially with regard to the evolving (and expanding)
role of MPLS technology. The paper also identifies key questions you
should ask before migrating from a legacy infrastructure to an MPLS-enabled IP
VPN, discusses the benefits of migration, describes the types of companies that
would benefit from MPLS IP VPNs, and suggests what a business should look
for in an MPLS provider. The good news is that the early adopters of the technology
have implemented MPLS with great success, particularly as it relates to
network performance. The time has come for mass migration to the technology.
In enterprises today, Wide Area Networks (WANs) are no
longer operating behind the scenes. WANs are central to
the daily operations and core business of organizations large
and small. However, enterprises must choose from a variety
of ways to implement WANs. This eBook examines the
various types of Wide Area Networks (WANs), and why
IT departments gravitate towards specific WAN solutions.
In addition, the paper provides constructive guidelines
for organizations seeking Local Area to Wide Area
Network extension.
This document provides a checklist for planning a WAN (wide area network), outlining key areas to consider including overall objectives, costs and ease of management, enterprise-wide traffic capacity, location considerations, redundancy, user and access needs, applications and bandwidth requirements, and security concerns. It suggests questions in each area to help evaluate network migration and extension plans for the entire enterprise. The checklist is intended to help WAN planners design a total solution that meets all connectivity, performance and protection needs across all locations.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Unified Communications
Setting the Stage
Remember the first mobile phones? You could always tell when someone had one: they
walked hunched over like Quasimodo because of the heavy battery inside. We all coveted
them — everybody wanted one. They were so desirous that in the mid-80s the Sharper
Image Company actually sold a fake cell phone that had a suction cup on the end of the
handset cord that could be affixed under the dashboard, allowing the owner to drive down
the street looking cool.
Remember the first laptops? They were equally cool; we all wanted one of those as well.
But I’d be willing to bet that very few people reading this paper today carry a laptop
because it’s cool. My suspicion is that they carry a laptop because it has their stuff on it.
All the Microsoft Word documents, spreadsheets, presentations, images, PDF documents,
sound files, music, movie clips, and other digital paraphernalia that our work and personal
lives require are typically resident on our computers and must, therefore, accompany us
wherever we go.
However, what if the need to have the physical computer were to go away? What if there
was a way to have access to work-related content at anytime, anywhere in the world, on
any network, using any access device over any access technology? Would that not sim-
plify life dramatically and make use of the network more efficient and relevant? Well, that is
more than a possibility — it is becoming a reality today.

Enabling the Evolution
Three phenomena are making this evolution possible:
• Inexorable, steady migration of content from the hard drive on the user’s device (PC or lap-
top) to storage arrays located within the network — and managed by the network provider
or hosted by the enterprise.
• The growing proliferation of Unified Communications (UC) technology in the workplace,
which is enabling anytime, anywhere communications. UC applications include IP tele-

user devices to support remote sites and mobile workers. In essence, it allows any user on
any network to have access to any content on-demand, regardless of their physical loca-
tion, the device they’re using, or the access modality they’re employing. How important is
SIP in enabling Unified Communications? According to Frost & Sullivan, “End-to-end IP
communications that do not require protocol conversion anywhere between the customer
endpoints and the service provider data center will eventually deliver better quality and
greater efficiencies to businesses deploying unified communications. SIP trunking, there-
fore, becomes a driver of IP telephony and UC adoption.”2
This three-part migration facilitates a number of advantages, including increased enterprise
productivity through improved support for distributed workforces, timelier and higher qual-
ity responsiveness to customers, and reduced capital expenses (CAPEX) and operating
expenses (OPEX) for telecommunications infrastructures. And it gets even better. Using SIP
helps reduce the cost of networking, plus SIP trunks free the customer from being locked
into a specific system vendor or network provider — now and in the future.
Signaling the Future
Signaling — the process of establishing a call, invoking enhanced services required for the
call (many based on the Caller ID function), maintaining the call, and tearing it down at the
end — is performed by protocols that are part of the Signaling System 7 (SS7) network,

6. Why SIP Makes Sense Enabling the Evolution to
SIP Advantages and Applications
When deployed in a network, SIP offers distinct advantages that can be used to develop
powerful and compelling end-user applications. For example:
1. Intelligence at the Edge
»» SIP-enabled telephony systems offer most of the call processing and feature invoca-
tion procedures offered through traditional voice networks — but in a different way.
Traditional voice networks use a hierarchical, centralized, core-based protocol designed
around the limited requirements of telephone sets — which have no innate intelligence.
SIP, on the other hand, is a peer-to-peer protocol, which requires a different type of
network core infrastructure (preferably MPLS built on an IP platform) with a blend of
intelligence located at the edge (i.e., software or end-user device hardware or PBX),
complimented by more scalable, granular, and rapidly deployed services offered by
service providers.
2. SIP Is Part of the Overall IP Suite
»» As part of the overall IP suite, SIP is flexible and extraordinarily dynamic. Its functional-
ity can be extended to any number of applications, including enhanced signaling for
value-added services, VoIP, and XML-tagged applications. Because XML is used to
structure, store, and send information across the network, it works well with SIP in
environments where data needs to be retrieved and used, as in a call center environ-
ment where customer records must be accessed, or in a healthcare environment where
access to customer data is critical. As a “lightweight, text-based protocol,” SIP relies on
a text-based command structure that uses the now universally familiar HTTP syntax and
URL addressing, both ideal for delivering telephony over an IP network where the logical
integration of applications (e.g., voice, messaging, conferencing, and Web access) can
create an enhanced user experience.
3. Supports Any Network Transport Medium
»» Because SIP is an application layer protocol, it can ride seamlessly across any transport
scheme and be transported across any access modality — cable, DSL, private line,
Ethernet, and wireless. Thus, SIP can enable a broad range of applications and remote
session capabilities (such as mobile application delivery and supply chain management)
without the need to provision additional transport services. From an enterprise point-of-
view, this is critical because SIP offers seamless connectivity options for service deliv-
ery for branch locations, remote workers, or trading partners. Since U. S. enterprises
with 500 or more employees have an average of 62 branch office locations, with an
average of 53.5 employees per location,3 this is a significant benefit for the enterprise.

Office, 10 Sep 2008.
6 Solutions you want. Support you need.
7. XO Communications
4. Mobility and Presence Support
»» SIP is now incorporated into a range of user devices, including mobile wireless devices
and desktop clients. Using SIP, session establishment requests are not sent to a device;
they are sent to the network, which locates the user’s “presence” and establishes a
session based on the user’s current location and usage profile. Because SIP unshack-
les users’ physical location from their logical address, they can have fully integrated
corporate communications — regardless of location. They can also integrate instant
messaging and desktop collaboration applications.
Presence is a relatively new concept in the networking arena. The user’s client pub-

because the agent is out of the office, SIP routes the call to their remote location (blue arrow, lower

5. Virtual Numbers
»» A fifth advantage is the ability to utilize virtual numbers, an assignable telephone num-
ber that has no physical phone line associated with it. In most cases, virtual numbers
are forwarded to either a VoIP account or to an alternate fixed or mobile number. For
example, virtual numbers are perfect for sales forces, business travelers, small busi-
nesses, and field service personnel. With virtual numbers, businesses can also create a
local identity in markets that the company serves.
Example: Imagine a business serving customers in multiple, far-flung locations, such as
Dallas, Los Angeles, and New York City. The company seeks to create a local identity
in these markets by publishing phone numbers with local area codes instead of toll free

distance are key.”
6. Business Continuity and Disaster Recovery
»» SIP trunks, in concert with VoIP, can play a major role in business continuity and
disaster recovery. With a SIP-supported IP PBX, many businesses are now able to
design disaster recovery plans using plug and play phones, softphones, and IP PBX
programmability capabilities. What’s more, automatic reroute in IP environments is
possible, thus reducing the headache of planning for every contingency. For businesses
of any size, SIP trunks provide connections to the PSTN so that outbound calls can
be rerouted and delivered over an Internet connection when the normal connection (or
location of the connection) is unavailable.
Example: Workers can setup their laptop from home or a remote location as a virtual
office, using the softphone capability that can support “presence” to detect online sta-
tus of company employees, customers, and trading partners. Additionally, IP PBXs can
be programmed to redirect calls in seconds to different phones or locations in the event
of an outage at key company locations.
In addition, business-class service providers build multiple layers of redundancy into
their networks to provide for business continuity. A carrier should provision network
session capacity to support failover of traffic between designated sites. Service provid-
ers also should track session usage for each of their customer’s sites and implement a
primary/backup arrangement to manage overflow traffic. When sessions in one site are
fully used, the network automatically routes inbound traffic, normally delivered to the
first site, to the second site.

7. Supply Chain Support
»» The overall supply chain is enhanced when executed in a SIP environment. By con-
verging its voice, data, and expanding video/rich media applications, businessescan
enhance the end-to-end supply chain, thus measurably improving their effectiveness
and efficiency.
Example: Mobile inventory tracking devices not only speed up the overall execution of
supply chain management, but also reduce the errors associated with the logistics of
tracking constantly changing inventory. Supply chains are also early adopters of Unified
Communications applications.
8. Unified Communications and Conferencing Applications
»» Because as many as 91% of employees work outside of headquarters offices,4 collabor-
ative applications that overcome the challenges of distance are key. Videoconferencing
has slowly become a part of this equation, but the cost and difficulties traditionally
associated with setting it up and the need to go to a specific location to use it have
been showstoppers. Thus, videoconferencing and SIP have combined forces. Not only
do they offer anywhere, anytime video, but they also make it possible to incorporate
presence, screen sharing, Web sharing, and instant messaging.

SIP Trunking and Cost Benefits
With these advantages in mind, let’s now take a closer look at SIP trunking and the cost
benefits that SIP trunks make possible.
SIP Trunks
SIP trunks are one of the more remarkable offshoots of the SIP family of capabilities and
one of the more important enablers of SIP-dependent applications. SIP trunks are nothing
more than virtual circuits configured and delivered over an Internet connection, typically via
the private IP backbone of a VoIP-enabled carrier, as shown in Figure 2.
Figure 2. SIP trunks enable convergence to one IP connection over a standards-based con-
nection, eliminating the need for TDM-IP gateways.
SIP trunks are often used in conjunction with an IP PBX as replacements or “evolutionary
next stages” from traditional ISDN PRI or analog circuits. In fact, many analysts believe
that SIP trunks will ultimately replace T1 facilities in business networks. SIP trunks not only
make network deployment more flexible, but also make possible the seamless assurance
of operational continuity in the event of a network failure. Their popularity, which is growing
rapidly, is largely due to a collection of factors, including cost savings and overall reliability.
Some of the more relevant cost benefits are as follows.

Reduced Network Service Costs
Convergence implies that a single connection can serve multiple access requirements.
With SIP trunks:

12. Why SIP Makes Sense Enabling the Evolution to
Eliminating PRI Trunks and IP Conversion Devices
SIP trunks eliminate the need for PRI PBX cards and IP conversion devices on the customer
premises, typically referred to as TDM-IP gateways. This device supports the conversion from IP
packets to PSTN traffic, which is normally transmitted over an ISDN PRI. In addition to hardware
savings, better throughput is also achieved by minimizing a protocol conversion step.
Evolutionary Migration Path
Companies that are not ready to replace their legacy TDM PBXs but wish to deploy SIP trunks
can deploy media gateways at branch offices to convert TDM voice communication into IP voice
traffic (and vice versa), instead of installing a brand new IP system. Thus, legacy TDM PBXs
placed in multiple sites are being interconnected via IP networks with the help of gateways that
transform the PSTN traffic into VoIP packets.
Considerations for Implementation
Interoperability
As IP PBXs have come booming into the market, problems of interoperability have arisen with
regard to SIP. Almost all of the first-generation IP PBXs on the market were designed around pro-
prietary IP signaling stacks because universal agreement on a single protocol had not yet been
achieved. Ultimately, SIP was chosen as that universal protocol, and PBX manufacturers wrote
proprietary interfaces for their legacy TDM interfaces. This created problems for developers
looking to write interfaces for VoIP environments built on media server platforms, as well as com-
plications that required system-by-system interoperability testing or, in some cases, the creation
of software interfaces to perform a protocol conversion that ensures interoperability beyond very
basic connect-and-disconnect capabilities.
Security
Thanks to new encryption capabilities such as SIP Transport Layer Security (TLS) and Secure Real-
Time Transport Protocol (SRTP), security vulnerabilities are no longer a major issue for SIP imple-
mentations. Just as most enterprise organizations encrypt the data that transverses their network,
they are requesting that VoIP providers encrypt voice and data packets transmitted over their VoIP
networks. Encryption provides customers with an added layer of protection to maintain privacy of
VoIP communications and helps prevent unauthorized access to voice conversations.
Business-grade service providers offer enterprise SIP customers a choice of either or both of the
industry signaling standards for encryption: SIP TLS and SRTP. TLS is based on the earlier Secure
Sockets Layer (SSL) method of encryption and uses cryptography to provide endpoint authentica-
tion and communications privacy over the internet. SRTP was developed by a small team from
Cisco and Ericsson and defines a profile of RTP, intended to provide encryption, message authen-
tication and integrity, and replay protection to the RTP data.

E911 Requirements
SIP and Unified Communications extend the mobile nature of VoIP by enabling
communications on a range of wireline and wireless devices that are not tethered to a
physical location address. Today’s VoIP-enabled, Internet-based phones offer multiple
features for convenience of use that allow callers to use phones from virtually any Internet
connection. While this technology has many benefits for end users, it has created many
challenges for emergency communications call centers that were designed to receive
calls from landline phone services associated with a fixed address. So, how does a
carrier provide E911 services to remote locations; and what are the legal requirements for
providing back up and E911?
Interconnected VoIP service providers are required to comply with enhanced 911 rules
adopted by the FCC that are designed to integrate nomadic interconnected VoIP services
with the existing PSTN emergency 911 system. Careful planning and proper service

Conclusion: Making the SIP Decision
Like any large-scale technology shift, the move to SIP should be undertaken only after con-
sidering all options and determining that a SIP migration strategy is the right move for the
enterprise. In most cases it will be but it makes sense to ask the questions. Furthermore, it
is critical to seek the advice of SIP-seasoned professionals before undertaking the migra-
tion. The move to SIP is a relatively straightforward process. However, there is a level of
complexity associated with it that demands the help of a service provider already familiar
with the overall process. This is what they do — use them to your advantage.
SIP is a fundamentally important technology in the evolving converged network and will
play an increasingly important role in enterprise and SMB networks in the very near future.
The advantages listed above and the applications described in this paper are clear indica-
tors of its relevance as a protocol and as an enabler of service provider relevance in the
future. SIP, like VoIP, is a when rather than an if question in today’s enterprise. Its time
has come, and businesses of all sizes will be well served if they consider it as part of their
evolving network strategy.
