Traffic Grooming on Path Network

Free registration required

Executive Summary

In traffic grooming the authors are given an optical network with nodes linked by optical fiber strand that support a number of wavelengths (light-path) with fixed bandwidth capacity, C. A demand (request) over the network is specified by a pair of source and destination node. A request is associated with some capacity demand (request rate), required on each traversed link to transmit the request to its destination. Traffic grooming encompasses packaging of several low rate requests onto a light-path using Time Division Multiplexing technique for transmission. When more than one request is groomed into a light-path a device called Add-Drop Multiplexor (ADM) is needed for the opto-electronic conversion at each node where traffic is added onto or dropped from the light-path.
