一种新型机载战术网络下的内容驱动路由协议

A Content-driven Routing Protocol for a New Airborne Tactical Network

传统机载战术网络(ATN)紧耦合于作战应用,且未考虑到信息内容本身,导致ATN下的路由协议无法为不同的信息内容提供差异化的通信服务,难以满足任务需求动态多样的航空集群平台通信需求。为此,通过融合软件定义网络、信息中心网络和机载战术网络架构,提出软件定义信息中心机载战术网络架构,并以此架构为基础,设计内容驱动路由协议,为不同的信息内容提供不同等级的路由转发能力,从而为网络提供高效的差异化服务。仿真结果表明,与传统的迪杰斯特拉算法相比,内容驱动路由协议能够减少端到端时延,提高吞吐量与网络通信性能。

Due to the tight coupling of the traditional Airborne Tactical Network(ATN) in the fight application without considering the information content itself,the routing protocol for the ATN cannot provide differentiated communication services for different information content,and it is hard to meet the aviation cluster platform’s communication requirements,which has dynamic and various task requirements.Therefore,this paper combines the Software Definition Network(SDN),Information Center Network(ICN) and airborne tactical network architecture,puts forward the Software Defined Information Center-Airborne Tactical Network(SDIC-ATN) architecture.Based on this architecture,the Content-driven Routing Protocol(CDRP) is designed,which can provide different levels of differentiated routing forwarding abilities for different information content,and provides efficient differentiated services for network.Simulation results show that compared with the traditional Dijkstra algorithm,CDRP can reduce the end-to-end delay to some extent,improve the throughput and improve the network communication performance.
