1. Silicon Switch Processor. High-performance silicon switch for Cisco 7000 series routers that provides distributed processing and control for interface processors. The SSP leverages the high-speed switching and routing capabilities of the SSE to dramatically increase aggregate router performance, minimizing performance bottlenecks at the interface points between the router and a high-speed backbone. See also silicon switching and SSE. 2. Switch-to-Switch Protocol. Protocol specified in the DLSw standard that routers use to establish DLSw connections, locate resources, forward data, and handle flow control and error recovery. See also DLSw.
Signal Switching Point. SSPs are points within the signaling system number 7 (SS7) network that terminate SS7 signaling links and also originate, terminate, or tandem switch calls.
Service Switching Points. Service Switching Points are telephone switches interconnected by SS7 links. SSPs perform call processing on calls that originate, tandem, or terminate at that site. SSPs generate SS7 messages to transfer call-related information to other SSPs or to query an SCP for routing instructions.
Switch-to-Switch Protocol. Protocol implemented between two DLSw routers that establishes connections, locates resources, forwards data, and handles error recovery and flow control.
A switch that originates or terminates a call.
