Chapter 2 Functional Description
Route Processor Card
In systems with the RSP card, the switch fabric is capable of delivering 80-Gbps per line card slot. In
systems with the RSP-440 card, the switch fabric is capable of delivering 200-Gbps per line card slot.
The switch fabric is 1+1 redundant, with one copy of the fabric on each redundant RSP card. Each RSP
card carries enough switching capacity to meet the router throughput specifications, allowing for full
redundancy.
In the Cisco ASR 9922 Router and Cisco ASR 9912 Router, the switch fabric element has been moved
to dedicated FC cards that connect to the backplanes alongside the RP cards. The switch fabric is capable
of delivering 550-Gbps per line card slot.
When five FC cards are installed in the chassis, the switch fabric is 4+1 redundant. When all seven FC
cards are installed in the chassis, the switch fabric is 6+1 redundant. The switch fabric is fully redundant,
with one copy of the fabric on each FC, and each FC carries enough switching capacity to meet the
chassis throughput specifications.
Figure 2-9 shows the switch fabric interconnections.
