Today is the day SDN realizes its potential.
This morning we launched the Corsa DP2000 series, our new open SDN switching and routing platform that redefines how network operators deliver subscriber-level networking, on-demand services and real-time network tuning. And it arrives not a moment too soon.
Metro network traffic is growing steadily and rapidly. That trend will only continue. But it’s not just the sheer volume that creates problems for architects and operators. Multiple nodes combined with varying traffic flows and a wide mix of services and bit rates adds to the challenges. Consider the explosive Internet of Things (IoT) trend, or the increase in instances of virtual reality layered on top of video. Traditional network architectures just cannot cope with these demands.
The Corsa DP2000 platform provides WAN-scale multi-context virtualization of the hardware to address these issues. For the first time ever, 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 more efficient use of hardware resources.
To achieve subscriber-level networking, the DP2000 platform has an architecture that achieves line-rate throughput during OpenFlow packet classification while allowing all manner of table lookups. Programmable PPUs with an intelligent construct of DDR3 memory and TCAMs combine with non-compromising packet processing to produce the scale, throughput and traffic engineering required for 10G-100G links in WAN and metro edge networking.
Built on this platform of advanced traffic engineering, Corsa offers SDN traffic management with full programmability of metering and policing on every flow using open standard interfaces such as OpenFlow Meter tables, as well as REST APIs. This gives network architects full programmatic control over their QoS policies in real time.
Those are some of the benefits and capabilities we offer networking professionals today. And I’m confident that we can mark today’s date on the SDN timeline in ink. The DP2000 platform is future-proof.
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.
Additionally, the Corsa hierarchical traffic manager supports tens of thousands of virtual queues, and tens of thousands of shapers. You can configure shapers on both physical ports and to logical ports on VSIs. This allows access to all available bandwidth over time without any loss of performance. That holds true even when packets are bunched together into micro bursts due to multiple speed and interface changes (10G to 100G to 10G for example).
Altogether, this enables innovative uses of the network, as well as allowing building of new services, such as performance-based QoS policy adjustment or Bandwidth on Demand.
The Corsa DP2000 series embodies our mission to promote and enable open, programmable networking that we call “Real SDN.” We are dedicated to delivering WAN-scale open, programmable SDN hardware platforms to our customers worldwide.
