SDN Done Right.
For the Physical Network.
Our goal with the Corsa performance SDN hardware platform is to enable you to architect a network that can be managed and orchestrated like a cloud computing environment, but that has the right performance characteristics at each point in the network without hitting limitations based on the physical network. Our platform is built to work within large networks with varying use cases and traffic patterns. Only Corsa performance SDN hardware has the features required for true WAN Optimized Switching, Routing and Forwarding.
The Corsa platform’s high performance hardware architecture provides internet-scale routing and fully programmable packet processing.
Supports wide mask TCAM entries to provide forwarding tables for all required services (Layer 2 switching, IPv4 and IPv6 Layer 3 routing, MPLS services and more)
Over 1 million active flow entries. Over 15,000 flow modifications per second
Analytics and statistics offloaded to dedicated hardware devices to avoid taking memory resources from PPUs and TCAMs
Corsa enables multiple virtual forwarding contexts (VFCs) within the same physical hardware with each operating at full line-rate performance.
Each packet is processed with full awareness to the virtual instance it belongs
Not limited to segmenting the hardware by physical ports
Assign logical attachment circuits (VLANs, MPLS pseudowires, GRE tunnels, VXLAN tunnels and others) to each VFC
Allows building traditional Layer 2 and Layer 3 services with new innovative SDN-enabled capabilities
Supports up to 64 independent VFCs
Using a high performance ASIC switch fabric in conjunction with flexible FPGA resources dedicated to packet classification and processing, Corsa delivers new levels of scalability.
Full range of connectivity options from 1G Ethernet to 100G Ethernet
10G Ethernet connectivity supports both LAN PHY and WAN PHY framing, allowing integration into existing optical and packet networks
Stacking to terabit scale without compromising performance for even the largest network locations while presenting as a single logical switch
Uses optical stacking cables to interconnect multiple devices into a single logical switch or router
Each front-facing stacking port carries 200 Gbps of traffic between Corsa dataplanes
Source optical transceivers from your preferred suppliers; no vendor lock-in
Traffic Management and Statistics
Corsa platforms provide full traffic management capabilities from full SDN traffic shaping on every physical and logical port, to fully programmable packet scheduling and queuing, to metering and statistics for every packet and flow that is going through the platform.
Traffic shaping on egress of physical ports or logical interfaces
Quality of Service (QoS) through dynamic programmable Two-Rate, Three-Color Meter table with eight queues per port
Metering on physical ports or logical interfaces
Traffic statistics presented via OpenFlow Channel, REST and SNMP
Precise per flow traffic awareness at any speed and scale available in real-time for every flow within the platform
Open SDN Programmability
Open programmability is at the core of Corsa products and why we enable programmable interfaces at all layers.
