一种混合式SDN网络的拓扑管理协议

A topology management protocol in hybrid SDN network

研究了混合式SDN网络的拓扑管理协议ARLP。ARLP可自动生成网络拓扑结构、并下发路由信息。当拓扑发生变化时,ARLP可自动检测到并下发更新的路由信息。仿真结果表明,当网络发生变化时,数据可切换到更新后的路由上,ARLP可提高网络的收敛速度,保证数据无缝传输。

A topology management protocol ARLP is studied based on the hybrid SDN network. The ARLP can automatically generate network topology graph and send out routing information. When network topology changes, ARLP automatically detects and updates routing information. Simulation results indicate that the data can be switched to the updated routing as network topology changes, and ARLP can improve the convergence rate of the network and ensure the data seamless transmission.
