Corsa Technology, a start-up based in Ottawa, unveiled new SDN metering and QoS (Quality of Service) capability for its line of performance SDN hardware. Bandwidth reservation is seen as especially interesting for organizations running Big Data workloads.
The traffic engineering function, which is based on OpenFlow 1.3, allows network architects to better manage bandwidth across their network with dynamic, policy-aware metering and QoS. Metering and queuing allows networks to create bandwidth profiles by putting limits and guarantees on traffic with particular classes.
Corsa said the advantage With SDN is that bandwidth limits are no longer fixed as part of a static topology and rigid hardware platform. Policy-aware provisioning can be dynamically pushed down to the flexible Corsa SDN hardware to make on-going adjustments to meters and queue assignments. The network can then make immediate, informed queuing and discard decisions under congestion. Real-time performance monitoring automatically returns meter statistics and is checked against policy such as SLAs. For network operators including service providers and ISPs, SDN metering and queuing allows new self-serve features to be offered such as “bandwidth reservation” where users can dynamically schedule and reserve bandwidth via separate class of service and meters.
“Dynamic, policy-driven networks is what SDN is about and SDN hardware solutions must be able to respond to these policy changes. SDN metering and QoS functionality is one important area for policy-driven networking requiring a very capable hardware solution,” said Yatish Kumar, Corsa Technology CTO. “Corsa’s line of performance SDN hardware has deep packet buffers, multi-table datapaths, and can support over a million active flows with flow modifications updated at >50,000 flow mods/sec. Together, these attributes make Corsa SDN metering and QoS a powerful tool for creating granular bandwidth profiles.”
