Abstract
A connection oriented switch, for example, an ATM switch, achieves scalable performance and enhanced reliability through a call processing architecture in which call processing functions are distributed to each network interface module rather than centralized in a call control module. Each network interface module has its own dedicated processor module that performs certain call processing tasks to off-load the processing burden from the call control module. Depending on the degree of processing power distribution, three embodiments include a distributed signaling architecture, a distributed call control architecture, and a distributed routing architecture.
