Optical Multicast Over Obs Networks: An Approach Based On Code-Words And Tunable Decoders
2014
Zenodo
Preserved Fulltext
In the frame of this work, we present an optical multicasting approach based on optical code-words. Our approach associates, in the edge node, an optical code-word to a group multicast address. ...
At the reception of a burst, it will be delayed in an optical memory. And, the received optical code-word is split to a set of tunable optical decoders. ...
Recently, optical code-words present the most promising approach for optical multicasting which allows denoting a multicast group in optical networks. ...
