Summaries are made concerning the typical network optimization problem . the paper independently puts forward several optimal methods to improve network traffic transmission , such as the maximum - flow problem over mpls , including the arc - based and path - based solution , which adopt the method of splitting and unsplitting traffic , the solution to the greatest reliability of transmission , the solution to concurrent maximum - flow for load balance via linear programming . on the basis of mpls path protection several protection methods over mpls are proposed , including n - to - 1 , n - to - m protection solution in splitting and unsplitting cases and in diffserv cases , whose partial simulation results are provided as well 即: 1 ) mpls网络最大流传输问题,包括基于弧的最大流解决方案、基于路径的最大流解决方案,分流与不分流的最大流处理方法以及多源多汇最大流解决方案; 2 )最大可靠性传输问摘要博士论文题: 3 )基于弧的求解流量负载平衡问题的线性规划方法; 4 )基于路径的流量负载平衡方法以及其他负载均衡问题; 5 )在mpls路径保护的思想和方法的基础上,提出了基于mpls的若干新的路径保护方法,即n一t 。
To satisfy the need of metro wdm survivability , two types of protection strategies , namely , share - fiber virtual - path protection and single - fiber bi - directional ring networks dni protection , are given in chapter 4 . the former is suitable for a complicated on such as a mesh network using the optical ring protection 此外我们首次针对boadm结构给出具体的在环网浙江大学博士学位论文中实现保护的策略,并把dni保护方式运用于全光网中,完成单纤双向光网在多种环网结构下的保护。
