Main Characteristics
Advanced System Structure
The switching system based on Salience III switch engine is a layer-3 distributed
switching structure consisting of the central Crossbar on the switching engine, Crossbar in
the interface board and shared memory packet processor.
Each switching engineer includes multiple route engines and one or two large-capacity
Crossbars. The route engine is responsible for the route calculation and synchronization
of system. Crossbar is responsible for across-board service switching. Each interface
