基于分布式协作的高可靠性隧道通信

为解决隧道长度较长时,通信故障定位时间长、故障恢复速度慢的问题,借鉴智能网络中的控制信令技术,设计了一种具有高可靠性的分布式协议,通过自组织的协作方式实现故障的快速定位、恢复. 该方法通过数据库扩散实现邻接节点之间的资源信息交互,完成相邻节点之间的信息互通,构建同步的资源数据库,在基于表驱动的先验式路由方式下对故障进行定位和恢复. 结果表明,该方法能够实现快速行车调度、环控调度且具有处理速度快、开销低、网络资源利用率高等特点,能够满足快速轻载的宽带地铁综合业务通信系统的需求.

Adaptive Coordination-Based Reliable Tunnel Communication Techniques

To solve the problem of the long failure locating time and achieve rapid failure restoration, a highly reliable distributed protocol is designed based on the principle of signaling mechanism of intelligent network. The failure can be located rapidly by the interaction between adjacent nodes in the tunnel by self-organized method. The synchronized database can be constructed under the table driven routing approach. The results show that with the proposed method, it can achieve rapid schedule of vehicles and tunnel control. The advantage of high speed, low overhead and high network resource utilization can fulfill the requirement of wideband integrated service communications.
