| 摘 要： | 为了实现Ad hoc网络中的端到端的可靠传输,利用带外信令与带内信令相结合的方式建立虚电路.业务发起点利用带内信令携带的链路建立消息和资源预留消息来预留反向虚电路,业务接收端在反向虚电路建立成功后,利用带外信令预约正向虚电路.对于网络拓扑变化所引起链路故障,采用反向链路故障通告和局部路由恢复相结合的策略进行修复.当虚电路建立起来后,可利用虚电路的面向连接特性,应用端到端的报头压缩策略,达到进一步减小网络中控制开销并缩小端到端的处理时延的目的.

| Abstract: | In order to realize reliable communication from end to end in Ad hoc networks, a bidirectional virtual circuit can be established through both in-band and out-band signaling. The service sponsor establishes reverse virtual circuit by in-band signaling and the service receiver sets up forward circuit by outband signaling. The link fallure due to dynamic topology can be restored by reverse error report and partial reroute scheme. With virtual circuit, quality of service guarantee and end to end header compression could be implemented to reduce the overhead and the end to end latency of the network thanks to the connection-oriented characteristic of virtual circuit. |
