中文摘要：

针对软件定义网络（SDN）易于获取链路状态信息的特点,综合考虑链路的时延和可用带宽两种因素的影响,提出一种多链路状态路由算法（MLSR）,并通过Mininet和Floodlight进行仿真.仿真结果表明：与文献中已有算法相比,ML-SR具有更低的传输时延和丢包率.

英文摘要：

Based on the feature that Software Defined Networks（SDN）that can easily obtain the link-state information,this paper proposes a Multiple Link-state Routing Algorithm（MLSR）,with an integrated consideration of the influence of link delay and available bandwidth. And then the performance of proposed algorithm is evaluated based on Mininet and Floodlight. The simula-tion results show that MLSR has lower transmission delay and packet loss rate than other existing algorithms presented in literature.
