摘要
本文研究了光网络的生存性问题,提出了光网络M∶N保护的两种优先排队模型,给出了相关的信令协议,通过仿真验证了模型的正确性.此模型可用于基于优先级的M∶N保护设计,有助于保护通道数的选取,从而确保一定的可靠性要求,同时避免过度配置而造成资源浪费.
The survivability issues of optical networks are studied in this paper. Two strict priority queueing models for M：N protection in optical networks are developed. A signaling protocol is also presented. The analytical models are validated by simulation. These models are helpful to the selection of appropriate number of backup paths in a priority-based protection design in optical networks to satisfy certain reliability requirements and to avoid resource over-provisioning.
