在大容量高速骨干网络的规划运营中
网络的生存性能和资源利用率是两个关键问题.在网络服务差异化的趋势要求下
如何使网络尽可能地满足不同的服务要求并且降低网络的成本
成为运营商越来越关注的问题.在本文中
我们提出了将预先规划和预先配置相结合的恢复策略
并在网络跨段容量相等的网络模型中进行了性能分析.指出要提高网络资源的利用率
需要折中考虑网络的保护率、备用路由的长度以及用于传送非保护业务的备用资源使用量.
For the design and operation of high-speed broadband network
survivability and efficiency are two essential problems.How to satisfy the different service requirements as well as reduce the cost of network becomes increasingly concerned.In this paper
we propose a new restoration strategy which is based on combination of the pre-planning and pre-configured methods.Through the performance analysis in fixed span capacity network model
it shows that high efficiency can be obtained from a trade-off between protection ratio and the length of restoration path.
