New Corsa SDN platform delivers 10G, 100G network hardware virtualization



Corsa Technology announced its new Corsa DP2000 series, a new open programmable switching and routing platform that delivers 10G and 100G subscriber-level networking, on-demand services and real-time network tuning. The Corsa DP2000 allows network architects and operators to dynamically partition hardware into independent virtual SDN switches or routers operating at line-rate.

The DP2000 series allows network architects and operators to achieve true network virtualization on the same shared infrastructure via open programmable APIs which slice their networks into virtual switching and routing instances running at internet-scale throughput.

“The DP2000 series is the first switching and routing platform to offer open programmable networking on a platform where you can dynamically slice a single physical switch into virtualized line-rate switching and routing instances that can support 100G of throughput. What compute has been doing for years, we now make possible at the core of the communications network,” said Bruce Gregory, CEO of Corsa Technology. “We built this solution with WAN and metro applications in mind, because it is here that network architects are struggling to handle exploding volume and diversity of traffic and where our multi-context hardware virtualization has a huge impact.”

The Corsa DP2000 platform provides WAN-scale multi-context virtualization of the hardware to address these issues. For the first time, metro and WAN network operators can slice their networks into virtual switching and routing instances running at internet-scale throughput. This capability to create virtual service instances allows for improved bandwidth management for each tenant, traffic isolation for performance or security reasons, automation of new service commissioning, and efficient use of hardware resources.

Corsa’s multi-context hardware virtualization and advanced traffic engineering features help network operators take full advantage of SDN and build better networks. The DP2000 series offers network hardware virtualization enabling logical L2 and L3 network services via SDN programmatic control; subscriber-level internet scale networking with per flow traffic engineering and advanced traffic management; real-time network insights with per-flow traffic monitoring statistics; multi terabit throughput with switch stacking, and open SDN programmability at multiple abstraction levels.

Corsa has been working to improve the SDN network architecture by delivering SDN hardware that can scale for large network applications. Corsa DP2000 is proof of this and has been built on the Corsa performance SDN hardware base.

‘The DP2000 series can scale from 100G to 2.4T of throughput. That means future growth will not require any changes to the software platform. Hardware wiring can remain intact while virtually adding new capacity without affecting existing physical connections,” wrote Carolyn Raab, Corsa’s vice president for product management in a company blog post. “Additionally, the Corsa hierarchical traffic manager supports tens of thousands of virtual queues, and tens of thousands of shapers,” she added.

Each of the virtual service instances benefits from Corsa’s advanced traffic management and QoS features which control and shape traffic within each instance at the per-flow level to required rates as determined by the orchestration layer and network policy.

Network operators can fine-tune traffic paths to ensure individual customers, subscribers or services receive their appropriate bandwidth and throughput. In addition, per flow statistics for all traffic is available, offering real-time network insights at the granular level and enabling any manner of predictive traffic management or security.
