Sanctum Networks Breakthrough OpenFlow Data Acceleration Algorithm Delivers Record Line Rates of over 40Gbs

Wednesday, March 20, 2013 12:21 PM


Sanctum Networks Ltd has announced the initial results of a new “Flow” classification Algorithm called Enhanced Recursive Flow Classification or (ERFC). The new algorithm is an enhancement to the existing Recursive Flow Classification (RFC) and has shown exciting results which could have major implications for the Software Defined Networking (SDN) industry.

Sanctum made the announcement while giving the keynote address in the AsiaBSD Conference in Tokyo where it also announced the launch of the first NetBSD Many Core operating system for the Tilera TILE-Gx processor.

Nazneen Shaikh, MD of Sanctum’s R&D Headquarters in India says “the explosive growth in data and network traffic is creating unprecedented demand for more compute power and faster switching of data traffic. At Sanctum Networks, we recognised that this challenge would only be truly addressed with the adaption of powerful, energy efficient algorithms that can harness many cores. RFC or Recursive Flow Classification is one algorithm that is successfully used today by researchers and being contemplated for commercial products ”.

“However, Sanctum is delighted to be able to announce that we have successfully developed a new enhanced version of this algorithm, (ERFC) for OpenFlow switching. Our new algorithm is a software based solution for multi-dimensional packet classification, enabling much higher line rates of 40Gb and beyond to be achieved, with extremely efficient memory usage ”.

“We have tested our new algorithm in a real OpenFlow switching network environment which also included Intel based platforms. Using the Tilera TILE- GX manycore processor and were delighted to see the algorithm performing at 32Mpps on upwards of 10,000 flows, that’s a 2.1x switching capacity to realize fully non-blocking fabric”.

“In particular, our results show that the enhanced multi stage packet classification algorithm can classify multiple fields in excess of one million packets per second and a 50% higher lookup throughput, compared to most other software based OpenFlow switching solutions available today”.

Paul O Callaghan, CEO of parent company, Sanctum Technologies, added “The completion of the new operating system for the Tilera’s TILE-Gx many core processor and in particular, the exciting results seen from our new ERFC Algorithm, represent great progress towards our strategy to develop a truly disruptive Software Defined Networking (SDN) product and I’m delighted to also announce that over coming weeks we will be releasing news of two further algorithms aimed specifically at greatly enhancing the performance of OpenFlow and SDN based Switching. These algorithms and Tilera’s energy efficient multicore architecture, is a truly unique combination. The algorithms have been the result of almost two years hard work by our engineers based in India and I am confident these announcements will undoubtedly differentiate Sanctum Networks product within the rapidly growing SDN and Cloud markets”.
