大规模SDN设备共享ip资源管理分配方法研究

Research on shared IP resource management allocation method for large-scale SDN devices

摘要:

针对传统方法中存在的路径标识不明确和流量调度不合理等问题，采用SDN架构法对共享IP资源管理进行合理分配。依据SDN架构原理，结合MPLS格式对路径进行标识。采用流量调度方法解决标识过程中出现的交换信息过多问题，并设计流量任务调度表，以该表为依据，提出一种集中式IP资源分配方案。从物理角度出发，采用叠加网络结构设计理念，对流量传输情况进行分析，依据流量传输结果，实现逻辑状态下IP资源管理的合理分配。通过实验对比结果可知，采用SDN架构法对路径标识，精准度最高可达到85%，对于IP资源管理分配效果较好。

Abstract:

In view of the problems of unclear path identification and unreasonable traffic scheduling in traditional methods, the SDN framework method is used to allocate the shared IP resource management reasonably. According to the principle of SDN architecture, the path is identified in combination with MPLS format. The flow scheduling method is used to solve the problem of excessive exchange information in the identification process, and a traffic task scheduling table is designed. Based on this table, a centralized IP resource allocation scheme is proposed. From the physical point of view, the design concept of superposition network structure is adopted to analyze the flow transmission situation, and the reasonable allocation of IP resource management in logical state is realized according to the result of traffic transmission. Through the experimental comparison results, we can see that the SDN architecture method has the highest accuracy of path identification, which can reach 85%, and has better effect on IP resource management.
