Juniper Networks Switch Route Processor (SRP) module - control processor

Switch route processor (SRP) modules perform system management, routing table calculations and maintenance, forwarding table computations, statistics processing, configuration storage, and other control plane functions. The SRP module identifies which line modules are physically present in the chassis and monitors and controls vital functions on the line modules.

Each SRP module is a PowerPC-based system with its own memory, nonvolatile storage (NVS), and power converter. The SRP module works with the SFM modules and contains a switch fabric slice common to both modules.
