The CRS-1 is a high-end core router from Cisco Systems. It is capable of 40Gbps per slot and scaling to 92Tbps bandwidth [1].

[edit] Versions and Options

The CRS-1 comes in two major varieties, single and multi-chassis systems.

[edit] Single Chassis

The single chassis variety of the CRS-1 comes in 4, 8 and 16 line card configurations, providing throughputs of 320Gbps, 640Gbps and 1.2Tbps respectively. In this case, no external fabric shelf is required.

[edit] Multi Chassis

The CRS-1 can also run in a multi chassis mode, where the switch fabric is distributed across to a fabric chassis. In this case, up to 72 CRS-1s may be added with up to 8 fabric shelves, scaling up to 92Tbps.

[edit] Functionality

The CRS-1 has three main areas of functionality. At the front we have 4, 8 or 16 interface slots with 2 route processors.
