Processor-to-Processor Communication
The RSP/RP card communicates with the control processors on each line card through the Ethernet Over
Backplane Channel (EOBC) Gigabit Ethernet switch. This path is for processor-to-processor
communication, such as IPC (InterProcess Communication). The Active RSP/RP card also uses the EOBC
to communicate to the Standby RSP/RP card, if installed.
Route Processor/Fabric Interconnect
The RSP card has a fabric interface chip (FIC) attached to the switch fabric and linked to the Route
Processor through a Gigabit Ethernet interface through a packet diversion FPGA. This path is used for
external traffic diverted to the RSP card by line card network processors.
