Abstract

Owing to the need for performing linear operation

the traditional network coding/decoding algorithms are only suitable to be applied in the electric domain

while thanks to the development of the current all-optical devices

it is possible to realize logic calculus and shift operations.In order to introduce network coding into all-optical multicast networks

this paper studies the algorithms for generating network coding multicast trees and the methods for selecting the coding vector appropriate for optical network coding and simulates and analyzes the presented algorithm.The results indicate that the application of network coding to all-optical multicast can significantly improve the multicast performances.
