SDN at Citigroup Networking for Citi’s Software-Defined IT Infrastructure

Get the White Paper

March 3rd, 2015

In this white paper, an overview is provided of some of Citi’s key data center and networking challenges and the role of SDN in Citi’s evolving data center infrastructure to address these challenges. Rather than being solely focused on software APIs and controllers, Citi is leveraging a holistic view of SDN, incorporating both physical and virtual networking. The company has defined a phased SDN technology strategy for data center networking, covering a physical networking fabric, network overlays, management and control and cloud orchestration.

NetScout Bridges Gap Between Old and New Open Networking Worlds

July 28th, 2014

podcast_2_artworkAs the transition to open networking technologies progresses, NetScout seeks to add value by minimizing disruption and preserving excellent user experience by being a bridge between the old and the new worlds of open networking. At the Open Networking User Group or ONUG Spring hosted by Citigroup in New York City, IT business leaders discussed their transitioning to open networking technologies such as network virtualization or overlays, software-define WAN and LANs, linux based tools to automate the configuration and change management of networking, storage and servers, OpenStack, white box based underlays and much more. While no two firms are at the same point of transition, what was very clear is that all are in transition. Recorded recently at CiscoLive with Steven Shalita, Vice President of Marketing at NetScout we discuss how NetScout can bridge the transition from today’s networks to the new world of open networking.

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.
