Cisco CRS-3 Scales to 322 Tbps using QuatumFlow Processors

Cisco unveiled its next generation core router designed for handling the expected traffic growth of video transmission, mobile devices and new online services through this decade.

The Cisco CRS-3 triples the capacity of its predecessor, the Cisco CRS-1 Carrier Routing System, with up to 322 Terabits per second (Tbps) -- which is 12X of the capacity of its nearest competitor, according to the company. The CRS-3, which represents a $1 billion investment by Cisco, leverages the company's in-house developed QuatumFlow Processors. Several models of the CRS-3 will be offered, with commercial shipments expected later this year. Cisco will continue to offer the CRS-1 core router series.

The Cisco CRS-3 continues to feature the mid-plane design used in the Cisco CRS-1 with a three-stage switch fabric based on a Benes architecture.

Cisco said it is building tight linkages between the Cisco CRS-3, Cisco Nexus family and Cisco Unified Computing System (UCS) to enable unified service delivery of cloud services. Several key innovations behind the CRS-3 platform:

  • Network Positioning System (NPS) -- provides Layers 3 to 7 application information for best path to content, improving consumer and business experiences while reducing costs.

  • Cloud virtual private network (VPN) for Infrastructure as a Service (IaaS) -- enables "pay-as-you-go" for compute, storage and network resources by automating Cisco CRS-3 and Cisco Nexus Inter-Data center connections for Cisco UCS.

  • Cisco QuantumFlow Array Processor -- which unifies six chips to enable new levels of service capabilities and processing power.

AT&T recently tested the Cisco CRS-3 in a successful completion of a field trial of 100-Gbps backbone network technology, which took place in AT&T's live network between New Orleans and Miami.
