Extreme Networks Improves Operational Efficiencies with Shipment of ExtremeXOS® 15.3 Supporting OpenFlow, OpenStack and SDN Applications

SANTA CLARA, Calif., Feb. 14, 2013 /PRNewswire/ -- Extreme Networks, Inc. (Nasdaq: EXTR) today announced that it is delivering on its vision for Software Defined Networking (SDN) with the shipment this week of ExtremeXOS® v15.3, the company's single modular Operating System for data center, campus BYOD and the cloud.

Customers benefit from critical new features and support for SDN technology, including OpenFlow and support for SDN applications from partners such as Big Switch Networks and NEC. Extreme Networks is also shipping its OpenStack Quantum plugin, a downloadable software module providing a rich API for ExtremeXOS that enables orchestration and management of multi-tenant networks providing security, load balancing and data center interconnect infrastructure as network services.

With the release of ExtremeXOS 15.3, Extreme Networks supports SDN applications from Big Switch Networks: Big Tap, provides traffic monitoring and dynamic network visibility with flow filtering, and Big Virtual Switch (BVS), an application for virtualized data center networks which provisions the physical network into multiple logical networks across the stack, from Layer 2 to 7. Additionally, ExtremeXOS 15.3 delivers support for AVB (Audio Video Bridging), Identity Management enhancements, XNV Dynamic VLANs and GRE Tunneling enhancements. 

"With our new multi-tenant data center, SDN can streamline switch management and monitor the network using ExtremeXOS," said Pepi Randolph, CEO of Data Holdings, LLC, which is constructing a premier data center facility in Milwaukee using Extreme Networks network solutions.  "Achieving this from a centralized standpoint and with an open approach is critical to scaling services and data more efficiently."

"The new world of networking takes a commitment to progressive applications driven by SDN," said Jason Matlof, vice president of marketing at Big Switch Networks. "By working with Extreme Networks, developing useful applications that streamline operations, we are on the leading edge of this important movement."

"As we bring new OpenFlow and OpenStack features into the market with ExtremeXOS 15.3, customers are equipped to take advantage of the promise of software advancements that extend capabilities and further simplify their networks," said David Ginsburg, CMO for Extreme Networks.
