为了解决一体化融合网络动态接入设备出现的通信波动、流量负载均衡以及鲁棒性差等问题，结合软件定义网络（SDN）技术， 优化了基于主客观的精准成本模型，将指标阈值型G1法作为主观赋权法，将标准离差法作为客观赋权法，使用乘法集成法对主观法和客观法计算出的权值进行成本整合，给出了最终的链路成本。提出了一体化融合网络多路径选择算法，把优化后的成本组合运用到多路径迪杰斯特拉（Dijkstra）变种算法中，得到传输链路及组合成本。提出了一体化融合网络联邦路由拓扑和策略，使不同网络可以选择符合自身特征的多条路径并按比例转发。研究结果表明，所提方案优化了差异化路径选择和流量调度，增加了链路带宽利用率并减小了网络传输时延。

SDN-Based Integrated Convergent Network Routing Scheduling Mechanism

To solve the problems of communication fluctuation, traffic load balancing and poor robustness of dynamic access equipment in integrated converged network. By combining the technology of software defined network (SDN), the accurate subjective and objective cost models are optimized. The index threshold G1 method is proposed as the subjective weighting method, and the standard deviation method is proposed as the objective weighting method. The multiplication integration is used for weighted combination to give the final link cost. A multi-path selection algorithm of integrated fusion network is proposed, and the optimized cost combination is applied to the multi-path Dijkstra variant algorithm to obtain the transmission link and combination cost. An integrated federated network routing topology and strategy are proposed, in which, different networks can choose multiple paths that meet their own characteristics, and can be forwarded in proportion. The results show that the proposed scheme optimizes differentiated path selection and traffic scheduling, increases link bandwidth utilization, and reduces network transmission delay.
