Lippis Report 207: The Killer SDN Applications: Network Virtualization and Visualization

April 8th, 2013

nicklippis.jpgAt the last Open Networking User Group (ONUG) meeting in Boston organized with partner Fidelity Investments, it became very clear that there are two killer SDN applications: network virtualization and visualization. Some argue that network virtualization used for VM-VM networking is not an SDN technology, but I beg to differ. Sure, there are closed and open approaches to network virtualization, but over the next business cycle, the integration of OpenStack and OpenFlow will make it clear that network virtualization is an SDN application, especially as it’s extended to physical networks. The second killer app is network visualization—that is, the ability to monitor network traffic and tweak application performance.   At ONUG Rich Groves, Principal Architect at Microsoft presented his SDN based approach to network visualization he designed with Big Switch Networks, cPacket, IBM, Arista and other suppliers that everyone is now using.  Why is network visualization an SDN killer app? Because it uses SDN technology, and most importantly, lowers the capital cost significantly from existing network visualization approaches while also delivering an entirely new level of self-server flexibility. Companies, such as Big Switch Networks, Gigamon, Arista, Cisco, NetScout, Ixia/Anue, cPacket and others, are now positioning their network visualization offers within an SDN context and for good reason. In this Lippis Report Research Note, I focus on network visualization as an SDN killer app.

The Visibility Fabric Architecture–A New Approach to Traffic Visibility

April 8th, 2013

The volume of digital information created and replicated will grow from 1.8 trillion gigabytes in 2011 to 7.9 trillion gigabytes in 2015. IDC

By 2014 70% of IT risk and security officers in the Global 2000 will be required to report at least annually to their board of directors on the state of IT security within their organization. Gartner

There are many drivers to network visibility. The Gigamon Visibility Fabric architecture empowers network and security architects, engineers and operators to design and deploy an intelligent infrastructure by applying user-defined “map” logic to select the appropriate, relevant and critical network traffic flows and deliver them to centralized security, monitoring and management systems. This new approach can extend the network reach of tools to significantly improve return on investment, allows IT organizations to more efficiently manage and secure their network, and provides a solution that can quickly evolve and scale as network needs change.

The Virtual Blind Spot Best Practices for Monitoring Virtual Environments

By Ixia/Anue

The “many in” notions that VMs are built upon become problematic when trying to trace a packet, or analyze packet flow. Even worse, in most organizations, the teams that handle the physical network are different than those that handle virtualization, ensuring finger pointing in the case of any issues. In this paper, we will consider the growth of virtualization, and the visibility issues arising from a traditional implementation. We will then overview Ixia’s Anue Net Tool Optimizer (NTO) solution and demonstrate how its product capabilities can help customers today, while using existing and familiar IT assets you have already deployed.

Cisco Unified Access Technology Overview: Converged Access

Less than one percent of things in the physical world are network connected. In the near future, the growth of the Internet of everything (IoE), which Cisco defines as the convergences of people, process, data, and things, will make networked connections more relevant and valuable than ever before, creating unprecedented opportunities for countries, businesses and individuals. However, although the number of devices, applications and bandwidth demands are growing, the size of IT staff and budget remains static. IT organizations are struggling to manage the bring-your-own-device (BYOD) trend and growth of mobile devices and traffic.They face two main challenges:

● Complexity of managing separate wired and wireless networks, multiple management and network operating systems plus chaotic device onboarding processes.

● Inconsistency of wired and wireless architecture, policy, security, features and operations.

When compared with wired networks, wireless also does not have the same level of granular quality of service (QoS), policy and security enforcement close to endpoint devices. Cisco® Unified Access is an intelligent network platform for IoE to enable greater business agility, operational efficiencies and new connected experiences.
