ZK Research: Virtual Infrastructure Creates Communications AgilityAvaya Inc.
The role of the CIO has changed more in the past five years than any other position in the corporate world. Historically, the CIO and IT department has been responsible for managing and running the technology infrastructure and has had little to do with augmenting the business. Today, IT leaders are tasked with deploying technology to drive the business and be a catalyst for change.
Faced with depressing predictions of looming budget cuts cloud computing has come to the fore of discussions to uncover relatively short-term economies in IT functions within the public sector. But how much of the cloud story is hype? How different are cloud architectures to the web-server farms that organizations have had the means to access for well over a decade? And how realistic is it that core business systems will move out of the data centre to the cloud?

Creating a more sustainable gallon jug for milk.Gail Barnes
85% of fluid milk in the USA is packaged in monolayer HDPE packaging, with the result that any reduction in the amount of plastic used can have a major impact on reducing the carbon footprint.
This presentation discusses the results of studies of a progression of ways in which the amount of plastic used in the creation of gallon jugs can be reduced.
–Light-weighting through container design.
–Adding calcium carbonate as a filler.
–Light-Weighting + optimizing for calcium carbonate filler.
These results meet recommendations coming out of the Life Cycle Analysis study conducted by the Innovation Center for US Dairy which recommended light-weighting or container weight reduction as a key focus area for improvement in the supply chain impact of fluid milk.
A recipe for the gallon jug of the future is presented, and the hypothesis made that “Integrated Design” will be the next frontier in creating a more sustainable gallon jug for milk.

3. Introduction
The need for data center transformation has taken on a new urgency. From the now mainstream
and widespread adoption of server virtualization to the more forward-looking opportunities of cloud
computing and desktop virtualization, companies are taking the initial steps necessary to deploy a
next-generation data center switching network, one that is more agile and adaptable to the changing
needs of the enterprise, and at reduced costs.
In order for the data center to truly evolve, the network must now be modernized. This modern data
center network needs to respond to the new requirements of server and desktop virtualization. It
also needs to deliver a high-quality user experience, especially for real-time applications such as video,
collaboration and video surveillance that executives now consider essential to their organizations’
responsiveness, creativity and security. As the number of mobile devices begins to overtake deskbound
and office-bound equipment, the network must also support the plethora of smartphones, tablets and
other mobile devices infiltrating the organization that are often no longer under control of the IT
team and thus cannot be tuned for application delivery.
Virtualization, new applications and new devices require moving away from the old multi-tier
network architecture in the data center to a true switching fabric that provides low-latency, any-to-any
connectivity. An innovative data center switching fabric can form a “mesh” network that enables a
range of innovative data center deployment models — from dedicated virtual data centers to multi-site
private clouds to a hybrid cloud environment — while providing a high quality user experience, agility
and reduced costs.
In this white paper, you’ll learn why the traditional data center network infrastructure is under
extreme pressure, what changes need to happen to modernize the data center network infrastructure,
and how an application-fluent approach can help ensure a successful step-by-step transition toward the
next-generation enterprise data center switching fabric.
“Virtualization and distributed applications are transforming every part of the data center. To maximize the
potential of virtualization, the network must also transform.”
- Yankee Group
A Perfect Storm of Network Pressures
While everyone was focused on new applications, server virtualization, sustainability, mobility,
security and other key initiatives, the pressures on the very heart of the data center grew insidiously
and significantly. Of course, we are referring to the data center network, where the types of traffic
and density of data loads are continually changing. At one point in time, most network traffic flowed
between a server in the data center and the desktop (north to south traffic). Now server-to-server traffic
(east to west traffic) is expected to surpass server-to-desktop traffic in the enterprise. Current data center
networks were never architected to be efficient for server-to-server traffic. This is creating tremendous
stress on the existing network infrastructure, threatening the ability of the data center to continue
meeting the increasing expectations of the business.
Virtualization
Virtualization, while bringing proven benefits to the organization, is a major culprit in putting
additional stress on the network. According to Gartner, between 2009 and 2010, the number of virtual
machines in corporate data centers increased more than 50 percent.1 Yet the traditional data center
network is not optimally designed for server and desktop virtualization. For instance, there was a time
when a Spanning Tree Protocol (STP) made sense in terms of balancing asset utilization. But in today’s
highly virtualized environment where low-latency, server-to-server connectivity is needed, a spanning
tree is no longer viable. Of course, the notion that an application may automatically and dynamically
change location in the data center is completely new and something that data center networks were
never designed to accommodate.

4. Real-Time Applications
At the same time, new applications — many of them requiring real-time communications — are also
pushing the network to its limits in terms of bandwidth. Social media sites such as Facebook, YouTube
and Twitter have redefined the way we interact in our personal lives, but they’ve also made a significant
impact on business. In a recent Frost & Sullivan survey of 200 C-level executives in North America,
nearly half of the respondents reported that their organization uses social media.2 The rise in social
media use has lead to increased employee and executive expectations for the availability of capabilities
such as on-demand media, high-bandwidth connectivity and flawless audio/video playback (in many
cases, high definition).
Mobile Devices
In a 2010 CIO magazine survey, more than two-thirds of IT leaders believed that mobile technology
facilitates business innovation in their organizations.3 Whether smartphones, tablet PCs or other mobile
devices, these technologies are not only changing the way we work, but they are also changing the
requirements for application delivery. With the rise of end user-owned devices, IT can no longer rely
on the ability to tune application delivery at the endpoint. The network needs to become application
fluent, that is, taking over the function of understanding the needs of the application and tuning for
application delivery performance.
Video
With the rise of Web and video conferencing, video surveillance and streaming media, video is
now commonplace in the work environment, which creates substantial new demand for quality-
controlled bandwidth. In the past, IT departments increased capacity as needed by simply adding
more raw bandwidth capability to the network, but that is not economically viable in today’s media-
rich environment. A better approach is required where the network can dynamically allocate available
bandwidth based upon business priority.
Modernizing the Network: An Application-Fluent Approach
With bandwidth-intensive video applications, virtualization, and new devices being introduced into the
enterprise at a rapid pace, it’s critical that the network, including the data center, understands how to ac-
commodate and dynamically adapt to these increasingly demanding workloads. Building on the model
that Gartner calls “application fluency,” Alcatel-Lucent Enterprise has adopted an application-fluent
approach toward architecting the next-generation data center network.
The Application Fluent Network is based upon a resilient architecture with automated controls in which
the network dynamically adapts to the application, user and current device to provide a high-quality user
experience, as well as simplified operations. This is achieved through a design that is built on three core
pillars and is applied to the data center as follows:
• Resilient architecture: Simplifies the network through a data center fabric that provides low-latency
connectivity, has a small footprint, and is ready for the convergence of storage traffic. Virtualization
of the network allows for any-to-any connectivity, supports the definition of virtual data centers, en-
ables coexistence with the cloud and supports Ethernet Virtual Bridging. It also ensures resiliency
due to localization of individual component failures, and offers built-in security.
• Automatic control: Includes the ability for applications to be managed as services, where the
network understands each application, adapts to virtual machine movement, and dynamically al-
locates bandwidth.
• Streamlined operations: Offers automated, low-touch provisioning of top-of-rack switches and ap-
plications. The design provides vendor-agnostic integration between the application virtualization
platform and network management platforms, with the lowest power consumption possible.

5. According to Gartner, an application fluent and scalable network can help enterprises maintain busi-
ness continuity and meet user SLAs4 by addressing both the internal and external forces that can impact
application delivery. At the same time, an application fluent network can serve as a foundation for data
center transformation, empowering the enterprise to further evolve towards a more flexible, powerful
and simplified computing environment.
A Roadmap for Application Fluency in the Data Center
Figure 1 depicts the path for moving from a client-server computing model to application fluency in
the data center. The path includes two important milestones for corporations: virtualizing the network
itself with deployment of a switching fabric, followed by convergence of data and storage networks. The
diagram also highlights the network requirements imperative for success at each stage.
Many organizations have already made the critical first step toward application fluency with server
virtualization. Unfortunately, many have not been able to reap all of the benefits of server virtualization
because virtual machine (VM) movement requires manual intervention to modify network provisioning.
That is one reason why network virtualization is the next step on the path.
Network virtualization enables the data center switching network to route traffic based on the optimal
path in the network without being constrained by the underlying physical connectivity. Virtualization
of the network delivers a switching fabric with low-latency, any-to-any connectivity. Equally important,
a true data center fabric must automatically adapt to virtual machine movement to relieve IT of the
burden of manually provisioning the network.
The choice of virtualization technology for the data center fabric is key to efficiently enabling a multi-site
data center and connectivity to public cloud services. Ideally, the virtualization technology would allow
the data center network to appear as a single, logical fabric capable of being physically spread across
several corporate sites, as is the case with Shortest Path Bridging (SPB). This ensures that IT has a more
efficient, unified framework to manage operations across multiple data center sites. Having all of the en-
terprise data centers connected in this way, in effect, transforms the corporate data center into a private
multi-site cloud.

Convergence of storage and data onto Ethernet is expected to become more prevalent as 40GigE con-
nectivity becomes more readily available. This will be due to the combined data and storage bandwidth
requirements of many virtual machines placed on a single server. Key technologies, which include lossless
Ethernet (also referred to as Data Center Bridging [DCB] and Fibre Channel over Ethernet [FCoE]), are
still being finalized in the standards committees and are a key requirement to support the reliable delivery
of storage over Ethernet. Any data center fabric deployed today should be ready to support these protocols.

6. Ultimately, new embedded security technology and 100GigE connectivity will enable a true hybrid
cloud model for corporations — one that allows organizations to mix and match resources as they see fit,
while keeping mission-critical data on premise.
The Fabric for Change: Bringing Application Fluency to Data Center Switching
What does it take to move from a multi-tier switching hierarchy to a true fabric in the data center? It
requires an innovative blueprint for application fluent data center switching that offers the low latency,
high density and sustainable design that enterprises need as they evolve their data center network. It is
essential that the blueprint offer an incremental ability to deploy the new fabric in the data center, while
also incorporating the essential capabilities for optimizing the user experience, improving network man-
ageability, increasing agility and reducing costs. To deliver on these capabilities, Alcatel-Lucent Enterprise
introduced its unique blueprint for application fluent data center switching that includes:
The Alcatel-Lucent Pod
Virtualization in the data center requires enterprises to optimize server-to-server traffic while striving to
reduce costs. Alcatel-Lucent’s Pod employs a unique direct-connect architecture for top-of-rack switches as
shown in Figure 2. The Pod is a highly dense structure that allows server-to-server traffic to be delivered
without the need for a core switch. The example shown in Figure 2 interconnects six top-of-rack switches
delivering 240 server-facing ports while keeping latency between servers in the same pod at less than two
microseconds. The network virtualization technology used is Shortest Path Bridging (SPB) and Virtual
Chassis, to allow all top-of-rack switches to be managed as a single device with one IP address.

The Alcatel-Lucent Mesh
Alcatel-Lucent Mesh delivers a complete switching fabric that can bring together more than 14,000
server-facing ports with only two core switches, delivering aggregate end-to-end latency of five microsec-
onds and unmatched resiliency 5. The Mesh is constructed by interconnecting Pods and core switches
as shown in Figure 3, again using SPB for network virtualization. SPB provides full interoperability
with data center interconnect technologies for multi-site private and public cloud deployments. The
Mesh enables enterprises to create virtual data centers supporting defined workgroups or departments.
Also, the Mesh is ready for storage to be converged onto the same fabric with lossless Ethernet, FCoE
or native Fibre Channel interfaces, and all switching is done in the fabric with Ethernet Virtual
Bridging (EVB).

What is a network fabric?
Simply put, it’s a flat network where every port is virtually connected to every other, providing high-speed, low-
latency interconnectivity. It’s operationally simple, allowing the network to be managed as a single entity rather
than as individual components.
Virtual Network Profile (vNP)
The Alcatel-Lucent Enterprise Virtual Network Profile (vNP) is shown in Figure 4. Using vNP, the
virtual machine applications are managed as services where the network understands each application
and can automatically adapt to optimize application performance, including automating the movement
of virtual machines within the fabric, agnostic to the choice of server virtualization platform. The vNP
contains the critical information the network needs to understand each application, including provi-
sioning requirements, security profiles such as access control rights and VLAN assignment, expected
quality-of-service levels, the priority of the application with respect to other applications, and specific
latency and jitter requirements. With this knowledge, the vNP can manage applications as services, en-
abling the network to automatically discover the location of each virtual machine, bind a specific vNP to
that virtual machine, and provision the network for the applications, including modifying the network
configuration to follow virtual machine moves.

As enterprises move further along the application-fluency roadmap, their data center fabric will enable
them to begin taking greater advantage of the benefits of cloud computing: increased agility, faster provi-
sioning and rollout of new services, simplified management and reduced costs.
Customers can begin preparing to leverage public cloud services by migrating their data center to
a private cloud architecture, where IT resources are dynamically allocated across the business in an infra-
structure-as-a-service model. This brings the benefits of fast deployment and scalability expected of the
cloud while still delivering the control and security that organizations desire. Alcatel-Lucent Enterprise’s
blueprint lets enterprises transform the corporate data center into a multi-site, private cloud by enabling
the data center switching fabric to become one logical structure that can be physically spread across
several corporate sites.
With the fabric acting as one entity, it helps simplify management and improve security. The fabric can
be partitioned to support virtual data centers for specific departments. An application or service can ex-
ist in more than one virtual data center and security can be applied differently within each virtual data
center and at virtual data center boundaries. The virtual data center boundary is adjusted automatically
to account for virtual machine movement.
It is critical for data center decision makers to make informed technology choices, such as SPB, to enable
the corporate data center to become a multi-site private cloud. Alcatel-Lucent Enterprise is working to
drive the SPB standard for network virtualization, as it believes that this is the optimal strategy to enable
a hybrid cloud model, depicted in Figure 5.
In the hybrid cloud model, public cloud services are seamlessly delivered onto the data center fabric
where they can be combined with local services to provide composite applications for users. The hybrid
cloud model lets enterprises broaden the flexibility, availability and scalability of the IT environment
without sacrificing the security and control available with a private cloud. To enable the flexibility
needed for the hybrid cloud, the choice of a service provider-compatible virtualization technology, SPB,
and the ability to manage applications as a service with vNP are essential.

9. The Benefits of the Application Fluent Data Center Network
With the Alcatel-Lucent Enterprise Application Fluent Network, enterprises get the flexibility they
need to move beyond costly client-server computing in a step-by-step, incremental manner starting with
the deployment of a single Pod. Organizations can start to benefit from an application fluent data ap-
proach and manage applications as a service across a range of data center deployment models, includ-
ing multi-site private clouds, dedicated virtual data centers and a hybrid cloud that integrates service
provider offerings.
For enterprises, application fluency delivers benefits across the organization, from the end user to IT to
the corporate bottom line. With an Application Fluent Network from Alcatel-Lucent Enterprise, organi-
zations can:

Conclusion
The data center infrastructure is undergoing a rapid transformation to drive down costs and improve
the end user experience in the face of rapidly evolving technology trends. This is causing fundamental
changes in how data centers are designed and how data center networks need to evolve. Not only do
data center networks have to adapt to the higher bandwidth requirements of media-rich applications like
video, they also need to support a wider variety of devices and connectivity methods. At the same time,
the network must be optimized for server and desktop virtualization, while enabling network virtualiza-
tion as the next step in modernizing the network.
Alcatel-Lucent Enterprise provides a new approach to networking in the data center — application flu-
ency. Following this application fluent approach, Alcatel-Lucent Enterprise provides a new blueprint
for a complete data center switching fabric which extends the boundaries of the data center through
virtualization of the network with an innovative direct-connect architecture. Leveraging market-leading
scalability, low latency and low power consumption, enterprises can move beyond costly client-server
computing by managing applications as a service across a range of data center deployment models, in-
cluding multi-site private clouds, dedicated virtual data centers and a hybrid cloud that integrates service
provider offerings.
The Alcatel-Lucent Enterprise Application Fluent Network helps enterprises ensure a high-quality end
user experience and more simplified operations. With the right approach and a trusted partner to
work toward application fluency, enterprises can feel confident moving forward in their data center
transformation.
