英文摘要： It is a key and difficult problem to maximize multicast switching and routing throughput all along in the all-optical network layer in the future Info-communication network. The contents of project research focus on the problem of maximizing multicast throughput theory and method for optical multicast communication network. The research contents include but not limited to: ① The way to construct network code and the scheme to resolve multicast contention are studied for optical multicast switching node. Moreover, the network coding system and information flow scheduling strategy are optimized by the enhanced graph theory and information flow disassembling method. Through this research, we want to expound the relation between network code and maximal throughput for optical multicast. Also, we want to extend the information delivery theory to optical multicast minimize code cost and maximize network throughput. ② The maximum flow and minimum cut-set theorem and limit multicast information flow transmission are researched to expound the routing cost model considering network coding switching node and network coding link. We expect to find the laws between maximum information flow limit transmission and minimum optical multicast routing cost. Furthermore, the multicast routing strategy based-on minimal cost-constra
