摘要/Abstract

摘要： 为缓解数据传输时延和数据源节点的高负载，将命名数据网络（NDN）路由机制引入广域信息安全管理（SWIM）网络，采用分层方式对SWIM 中的信息进行命名，以提高路由聚合度；采用路由缓存策略，以提高网络对相同请求的响应速度；针对SWIM 可能出现的节点故障，提出一种重路由机制以降低路由故障后的信息传输延迟。仿真结果表明，该方案可提高网络对相同信息请求的快速响应能力和降低网络平均负载；在出现节点故障时，重路由机制可有效降低网络时延和平均重传次数，从而减小对网络性能造成的影响。

Abstract: In order to reduce the data transmission delay and the high load of data source node, NDN routing mechanism is introduced into SWIM network, naming the information in a hierarchical way to improve the aggregation degree of the route. Caching strategy is adopted to improve the response speed to the same request. Aiming at the possible node failure, a rerouting mechanism is proposed to reduce the transmission delay. Simulation results show that the proposed mechanism can achieve fast response to the same information request and reduce the average load of network. When node failure appears, the rerouting mechanism can effectively reduce the network delay as well as the average number of retransmissions, and reduce negative impact on network performance.

Key words: SWIM, NDN, forwarding strategy, rerouting
