Optical Multicast Over Obs Networks: An Approach Based On Code-Words And Tunable Decoders

Maha Sliti, Walid Abdallah, Noureddine Boudriga
2014 Zenodo  
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.  ...

Optical Many Casting Using QoS Depend Layer Aware Mechanism

R.C. Arun Chander, P. Karunakaran, S. Venkatraman, I.Hameem Shanavas
2012 International Journal of Information Technology and Computer Science  
Manycasting is performed over optical burst-switched (OBS) networks based on multiple qualities of service (QoS) constraints.  ...  The proposed layer aware FEC (L-FEC) generates repair symbols so that protection of less important dependency layers can be used with protection of more important layers for combined error correction.  ...  If the selection is done at the IP layer, manycast requests become multicast requests to the OBS layer, and it is sufficient that OBS networks support only multicasting service.  ...
