Performance Analysis of a New Switching Structure for Optical Multicast

As the new services emerge, multicast function is demanded in optical networks. However, due to the high cost and complex architecture of multicast capable node, the splitter-sharing switch structure is introduced. Then, in order to make full use of the splitters equipment, we first analyze using the NSFNet and come to the conclusion that when the number of splitters is 25% of the full equipment, the performance has been close to the ideal result. Then after thousands of virtual networks testing, we proved that it can apply to most of the topologies.
