Do you run an MPLS network to some or all of your branches? If so, you are likely wasting MPLS capacity backhauling Internet traffic.
For many organizations, a lot of the traffic is Internet-bound due to increased cloud-usage. Backhauling Internet traffic over an expensive MPLS service adds latency and puts pressure on limited and expensive MPLS capacity.
This paper focuses on the evolutionary stages for cloudification then covers the key software building blocks that will be needed to enable NFV, and ultimately ICT transformation to 5G. It describes how Intel® Open Networking Platform (Intel® ONP) Server running on innovative new networking platforms based on Intel® silicon can help reduce the cost and effort required for service providers and vendors alike to adopt and deploy SDN and NFV architectures.

SECURITY FOR SOFTWARE-DEFINED (CLOUD, SDN AND NFV) INFRASTRUCTURES – ISSUES A...csandit
Cloud computing has transformed a large portion of the IT industry through its ability to
provision infrastructure resources – computing, networking, storage, and software - as
services. Software-Defined Networking (SDN) has transformed the physical underlying network
infrastructure into programmable and virtualized networks. Network Functions Virtualization
(NFV) has transformed physical telecommunication infrastructures and network functions into
virtualised network functions and services. Cloud, SDN and NFV technologies and their
associated software-defined infrastructures all rely on the virtualization technology to provision
their virtual resources and offer them as services to users. These new technologies and
infrastructures invariably bring with them traditional vulnerabilities and introduce new
technology-specific security risks. In this paper, we discuss extensively cloud-, SDN-, and NFVspecific
security challenges as well as approaches for addressing integrated infrastructural
issues where cloud, SDN, and NFV all play their integral parts.

CONTAINERIZED SERVICES ORCHESTRATION FOR EDGE COMPUTING IN SOFTWARE-DEFINED W...IJCNCJournal
As SD-WAN disrupts legacy WAN technologies and becomes the preferred WAN technology adopted by corporations, and Kubernetes becomes the de-facto container orchestration tool, the opportunities for deploying edge-computing containerized applications running over SD-WAN are vast. Service orchestration in SD-WAN has not been provided with enough attention, resulting in the lack of research focused on service discovery in these scenarios. In this article, an in-house service discovery solution that works alongside Kubernetes’ master node for allowing improved traffic handling and better user experience when running micro-services is developed. The service discovery solution was conceived following a design science research approach. Our research includes the implementation of a proof-ofconcept SD-WAN topology alongside a Kubernetes cluster that allows us to deploy custom services and delimit the necessary characteristics of our in-house solution. Also, the implementation's performance is tested based on the required times for updating the discovery solution according to service updates. Finally, some conclusions and modifications are pointed out based on the results, while also discussing possible enhancements.

Wide Area Network Design
An enterprise network is a diverse and large network connecting most major points in a company, business or other organization. An enterprise differs from a WAN in that it is privately owned and maintained. There are a variety of WAN technologies to meet the different needs of businesses and many ways to scale the network. An enterprise must subscribe to a WAN service provider to use WAN carrier network services (Paquet, 2013).
In designing of the WAN portion of the network, the first step is to understand the specific network characteristics of the various locations from a Wide Area Network point of view and to then analyze and decide how to implement WAN connectivity at each location. The proposed WAN has specified both possible leased line as well as point to point radio connectivity between sites (Zhang, 2005). It is recommended that the wide area network connection between remote offices should be a point to point radio link. The Plant facility in one location has the capability of using satellite communications or other leased lines for this deployment. Also, for high availability it is recommended that all locations also have site to site redundant links over the Internet through the use of (virtual private network) VPN connectivity. VPN technology will enable organization to create private networks over the public Internet infrastructure that will maintain security and confidentiality. We will use VPNs to provide a virtual WAN infrastructure that connects branch offices to all or portions of their corporate network.
Different applications require varying amounts of network bandwidth the bandwidth required between these sites is dependent upon several factors that include amount of traffic (which varies depending upon the number of users connected to the network), number of hosts, number of network users, protocol being used, potential applications deployed on the network and the network design. For offices with lower bandwidth requirements the most recommended Frame Relay connection should provide no less than 768Kbps while locations with a larger bandwidth requirement will need point to point T1 connections (around 1.54Mbps). To determine which type of connection is appropriate at each location, a list of the approximate number of users and hosts at each site along with the applications they use will be we put in consideration when coming up with the equation for properly determining bandwidth requirements for the network. The required bandwidth in this case will be measured by first determining the amount of space available to transfer data. So for the T1 connections we need to divide 1.54Mbps by 8 to get the number of bytes per second available on the WAN connection. Therefore, a T1 connection will support 192 Mbps. Next, we will determine the amount of bandwidth needed for each application, which.

Cloud computing and Software defined networkingsaigandham1
This is my Graduate defense presentation. I have interest in various topics like cloud computing and software defined networking. This slides includes the research of various researchers on cloud computing and SDN, presented their work as my comprehensive exam.
New generations of applications call for new demands
that are totally different from previous uses of the Internet (e.g.,
cross-layer and network function virtualization), and the existing
networks are not optimized for these new demands due to being
overwhelmed by enormous numbers of external network
protocols. Overlay network technologies aim to respond to such
future network demands. Systems on overlay networks mitigate
this protocol overload by exploiting the unlimited
programmability of the overlay nodes comprising the system.
This paper proposes an overlay node that works as a transparent
proxy server and router for encrypted communication over
overlay networks. This overlay node acts as a virtual switch over
multiple layers of the OSI reference model (the datalink, network, transport, and session layers) using general-purpose components (a personal computer, physical network interface card, and
virtual network interface card, developed using the C language).
The ideas behind this proposal derive from the effectiveness of
software-defined networks and network function virtualization.
Finally, we examine the performance of the overlay node
experimentally and suggest possible designs for future overlay
networks.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Avaya Fabric Connect: The Right Foundation for the Software-Defined Data Center
1. Avaya Fabric Connect: The
Right Foundation for the
Software-Defined Data Center
This paper focuses on a specific real-world use case for SDN - the
Software-Defined Data Center. It provides Avaya’s perspective on
the characteristics of the Software-Defined Data Center and the
value of its Fabric Connect technology as the foundation for this
solution. It also talks about how combining Avaya Fabric Connect
with open-source cloud orchestration capabilities (that are being
defined by OpenStack) can enable a graceful migration to the
Software-Defined Data Center.
What is the Software-
Defined Data Center?
According to Webopedia, Software-
Defined Data Center (SDDC) is the phrase
used to refer to a Data Center in which all
the infrastructure components are
virtualized, packaged, and ultimately
delivered as a service. Control of
resources is automated by software –
meaning that hardware configuration is
maintained through orchestrated software
systems.
The SDDC is considered by many to be the
next step in the evolution of server
virtualization and cloud computing. As
components within the Data Center
(server, storage, networking) are
virtualized, the end game of the SDDC is
to combine, customize, and commission
resources from the server, storage and
networking pools to ensure that
applications or services meet the capacity,
availability and response time SLAs that
an agile business requires. The desire is to
deliver much more IT flexibility, efficiency
and agility in an organization’s business
processes so that IT Operational teams
can turn up new applications faster and be
much more responsive to their user and or
customer base.
Evolution to the Software-
Defined Data Center
Avaya offers solutions that help
enterprises and service providers prepare
for the transition to the SDDC. Many Data
Centers that have deployed server and
storage virtualization already are now
focusing on network virtualization. This
new focus will result in significant benefits
by addressing what is currently the most
complex portion of turning up and fine-
tuning applications: coordination and
orchestration with the network.
The challenge with today’s
networks
Today’s server environment is dynamic.
New virtual machines can be spun-up in
minutes and can migrate between physical
hosts on-demand or dynamically. The
network remains relatively static
however, and a painstaking, error-prone
provisioning process to provide network
connectivity for applications is too often
required. To facilitate the movement of
applications between servers, Layer 2
VLAN extensions, both within the Data
Center and across the backbone
infrastructure between Data Centers, are

Today many point to
software-defined
networking (SDN) as
the next big thing in
networking. But
what is it really?
Initially it was closely
associated with
OpenFlow which
provides separation
between control and
data plane so that
each could be
independently
managed. But now,
sparked by new
technology options,
the definition is
broadening with
SDN being

2. required to provide a robust and
transparent connectivity service.
In today’s traditional LAN/WAN
design, the extension of VLANs and
their propagation within Data Centers
can prove challenging. Ensuring all
redundant links, in addition to
Switches, are properly configured can
be a time-consuming operation and
can introduce significant risk due to
the need to regularly administer
configuration of crucial core devices.
Furthermore, initiatives such as video,
BYOD, and Big Data are putting
additional pressure on today’s
networks and are causing many IT
and network operations teams to
reevaluate how they might evolve
their networks.
Network virtualization provides a
more dynamic and agile network
environment and - when the right
approach is taken - can provide
benefits to the network that are as
profound as those experienced by
applications when server
virtualization technology emerged.
Not all Network
Virtualization
Technologies are Equal
The concept of an Ethernet Fabric is
seen as a critical next-generation
network virtualization technology.
Ethernet Fabrics allow business to
replace obsolete Spanning Tree
Protocol-based networks; this
increases network efficiency through
genuine load-sharing across multiple
active links and increased availability
by setting up Layer 2 connections
between servers in order to facilitate
the migration of Virtual Machines.
Avaya’s dynamic, real-time, service-
based Fabric Connect technology is
the most advanced Ethernet Fabric
solution on the market today. Going
beyond simple Spanning Tree
replacement, it delivers the full
breadth of desired integrated services
including Layer 2 virtualized services,
Layer 3 virtualized services (with
multiple Virtual Routing and
Forwarding instances), and fully
optimized routing and integrated IP
Multicast support.
Applicable to single and multi-tenant
Data Centers, Fabric Connect enables
businesses to gradually migrate away
from a host of legacy technologies
(such as STP, OSPF, RIP, and PIM) and
to enable all services with a single
technology. Powered by edge-only
provisioning, Fabric Connect allows
new services or changes to services
to be implemented and also
eliminates the legacy requirement of
end-to-end provisioning, including
the core, to facilitate much greater
ease and agility. It also makes the
physical topology of the network
irrelevant by allowing any logical
topology to be built, whether it is
Layer 2, Layer 3, or a combination of
the two - to deliver new levels of
flexibility for network operators.
Eliminating complex protocol overlays
not only simplifies the design and
ongoing management of the network
but can also speed up network
re-convergence times dramatically.
Customers who have already
implemented Avaya’s Fabric Connect
are experiencing recovery times of
less than 50 milliseconds network-
wide for link or node failures which
represents a vast improvement over
large OSPF routed cores and massive
improvement when compared to
legacy solutions that relied upon PIM-
based Multicast.
Vendor lock-in is a common concern
for customers who are evaluating new
technologies and unfortunately most
vendor implementations of an
Ethernet Fabric technology are
proprietary. Avaya’s Fabric Connect,
however, is based on the Shortest
Path Bridging protocol – one of the
only technologies ever to be
standardized jointly by the IEEE and
the IETF. Being standards-based
means that Avaya Fabric Connect can
interoperate with the massive
installed-base of existing Ethernet
products and thereby allow
customers to deploy the technology
in areas where they need it the most
without having to do a full rip and
replace. Avaya Fabric Connect can
be, and often is, deployed alongside
legacy technologies – running as
‘ships-in-the-night’ – allowing services
to be migrated selectively without
impact.
Avaya is committed to providing an
open approach for the foundation of
the Software-Defined Data Center
and has been actively participating
with other vendors to demonstrate
Shortest Path Bridging
interoperability. An interoperability
test was conducted at Interop 2013 in
Las Vegas with major industry
vendors Alcatel Lucent, HP, and
Spirent.

Critical to the Software-Defined Data
Center is the ability to move Virtual
Machines between IP subnets within
the same Data Center (and even
between geographically dispersed
Data Centers) with new levels of ease
and flexibility. A key benefit of Avaya
Fabric Connect is that it offers
unrestricted VM mobility by
leveraging a single technology that
can extend seamlessly across
distance. Virtual Machines can
migrate on-demand or dynamically
between physical servers located in
geographically dispersed Data
Centers as easily as between servers
located in the same rack. This is
achieved without any of the complex
protocol stitching commonly
practiced by competitive Ethernet
Fabric technologies.
It is important to consider scale.
While the Shortest Path Bridging
standard enables scaling up to 16
million unique service instances,
competitive Ethernet Fabric
technologies are typically based on
VLAN virtualization which limits them
to the 4096 ceiling. This is clearly not
adequate considering that many large
Data Center environments are already
experiencing VLAN exhaustion and
are looking for a network
virtualization technology that can
solve this.
Finally, while many Fabric
technologies are designed exclusively
as Data Center technologies, Avaya
Fabric Connect extends network-
wide, providing a single service
delivery model end-to-end. Services
can be deployed via simple end-point
provisioning where servers attach and
where users attach. Users can request
access to the network and be placed
dynamically into the appropriate
Layer 2 or Layer 3 virtualized network
according to predefined policies.
Virtualized networks can be
dynamically created and can reflect
anything from separating different
departments in a traditional multi-
tenant environment to separating
different types of users (wireless
guests, executive access) and
isolating traffic types for security
and/or regulatory compliance (i.e.
banking transactions for PCI DSS
compliance, medical imaging devices
in a hospital). Network access is
completely automated – users and
devices are grouped into the
appropriate virtualized network
based on their credentials.
In summary, Avaya Fabric Connect is
unique in the market and offers a new,
innovative way to build, deploy and
manage networks that deliver new
levels of simplicity, agility and uptime.
The Value of OpenStack
Cloud Software
For a true Software-Defined Data
Center, being able to orchestrate,
coordinate, and allocate resources
from server, storage and networking
pools is critical to ensuring that
applications or services meet
capacity, availability and response
time SLAs required by business.
OpenStack is an open source cloud
operating system created by NASA
and Rackspace that simplifies
creation and movement of
applications and virtual machines in a
public or private cloud. Traditional
methods of configuring a network
and storage and virtualized servers
could take months and involve several
complicated independent steps.
OpenStack provides a control layer
that sits above all the virtualized
resources within the Data Center and
abstracts administrators and users
from the underlying components
which allows them to orchestrate
those resources as a service through a
set of APIs and a common dashboard.
From the integrated dashboard,
administrators can spin up virtual
machines, assign storage, and
configure networks through simple
point-and-click workflows. When
operationalizing new applications,
this technology makes operations
consistent across multiple
technologies and offers increased
agility and simplicity, especially in
multi-vendor environments where
multiple hypervisors, storage
technologies, and networking devices
may be present.
Within OpenStack there are several
modules that manage each resource
individually. Specifically, the
OpenStack ‘Nova’ interface
orchestrates virtual machine
resources, the ‘Cinder’ and ‘Swift’
interfaces orchestrate block and
object storage respectively and
‘Neutron’ interconnects everything by
coordinating networking services and
appliances. Typically this is brought
together under the umbrella of
OpenStack’s ‘Horizon’ graphical
orchestration interface.
