Heuristic algorithms for efficient allocation of multicast-capable nodes in sparse-splitting optical networks
Autor: Constantinou, C. K., Ellinas, Georgios N.
Publikováno v: Computer Networks
Comput.Networks
Optical splitters are utilized in optical nodes for splitting the received signal into multiple copies, in order to efficiently provide multicast capabilities in optical networks. In practice, only a fraction of the network nodes are equipped with op

This work proposes novel routing approaches for transparent optical networks where only a fraction of the network nodes are multicast capable (MC) and can split the optical power from a single input to multiple output ports. The remaining, multicast-

The current paper deals with the problem of survivable multicasting in mesh optical networks. A load balancing technique is presented that can be combined with any appropriate survivable multicast algorithm. Simulations on several test networks have

Survivable multicasting in sparse-splitting optical networks
Autor: Constantinou, C. K., Manousakis, K., Ellinas, Georgios N.
Publikováno v: Proceedings of 2014 6th International Workshop on Reliable Networks Design and Modeling, RNDM 2014
In this work, the problem of provisioning survivable multicast connections in optical networks is investigated, under the assumption that not all network nodes are multicast capable (MC). A MC capable node is a node that can forward the incoming sign

Survivable multicast routing in mixed-graph mesh optical WDM networks

A new multicast protection algorithm for mixed-graph mesh optical WDM networks is presented. Simulations show that the proposed algorithm outperforms the existing ones for this category of networks, in terms of blocking probability and average cost.

In the paper, a heuristic algorithm that deals with the problem of finding arc-disjoint trees in mixed-graph mesh optical networks is presented. A mixed graph is defined as one that has both unidirectional and bidirectional links between its nodes. T
