【摘要】：针对域内流量均衡问题,提出了一种二维开放式最短路径优先(OSPF)路由方案TOL。在控制层面,通过对传统链路状态通告(LSA)的扩展,实现包括目的前缀和源前缀的二维路由信息的传递,路由器根据二维路由信息进行计算,生成二维路由表项。在数据转发层面,设计了一种基于传统一维转发表实现二维数据转发的方案,这种转发方案能够有效解决引入源前缀造成的转发表存储空间增长问题,兼容传统转发,为TOL提供保障。为了验证TOL的有效性和可行性,在商用路由器上实现了原型系统,测试和实验结果表明,TOL方案能够在传统IP网络结构和协议的基础上,有效实现流量均衡,减少链路拥塞,且不会带来较大的额外负荷。
[Abstract]:In order to solve the problem of intra-domain traffic balance, a two-dimensional OSPF routing scheme named OSPF is proposed. At the control level, the traditional link state notification (LSA) is extended. To realize the transfer of two-dimensional routing information including destination prefix and source prefix, routers calculate according to two-dimensional routing information and generate two-dimensional routing table items. A 2D data forwarding scheme based on traditional one-dimensional forwarding table is designed. This forwarding scheme can effectively solve the problem of storage space growth caused by the introduction of source prefix, and is compatible with traditional forwarding. In order to verify the validity and feasibility of TOL, the prototype system is implemented on commercial routers. The test and experimental results show that the proposed scheme can effectively realize traffic balance on the basis of traditional IP network structure and protocol. Reduces link congestion and does not bring extra load.
