DYNAMIC ROUTING.

Abstract

Dynamic Routing exploits the intelligence of digital switches by connecting all the software-controlled machines in a network to a central mini-computer, then letting the minicomputer calculate the best alternative routes for the calls offered to each possible destination from each intelligent switch, using data supplied every few seconds by the intelligent switches. This traffic routing strategy allows more efficient use of trunk capacity than can be achieved with fixed alternate routing, adapts quickly to unexpected shifts in the distribution of offered traffic, and increases network survivability in the event of transmission or switching equipment failures.
