【摘要】：可靠性问题是电信网络优化设计的核心问题之一,在光缆网拓扑结构已知前提下,给出了满足可靠性要求的电信级服务质量有关业务的性能指标,建立了时延、时延抖动和IP路由跳数等性能指标约束条件,以最小化IP和传输两层网络建设费用为目标的非线性混合整数规划模型,然后重点研究可靠性问题,结合问题的分层结构,将其转化为结构可靠和带宽可靠两个子问题,分别给出了IP层节点失效和传输层路段失效两种情况的解决方案,测试结果说明了可靠性对网络流量的影响.最后对全文进行了总结,并对下一步的研究工作进行了展望.
[Abstract]:The reliability problem is one of the core problems in the optimization design of telecommunication network. On the premise of known topology structure of optical cable network, the performance index of telecommunication grade service quality related service which meets the requirement of reliability is given, and the delay time is established. The nonlinear mixed integer programming model, which aims at minimizing the construction cost of IP and transmission two-layer network, is constrained by delay jitter and IP routing hops. Then, the reliability problem is studied, and the hierarchical structure of the problem is combined. It is transformed into two sub-problems: reliable structure and reliable bandwidth. The solutions to the failure of IP layer node and transmission layer are given, respectively. The test results show the impact of reliability on network traffic. Finally, the full text is summarized, and the next research work is prospected.
