要求工作通道与保护通道不能处于同一个SRLG之中。文章提出了一种基于SRLG限制的动态共享通道保护算法——动态链路权重配置(Dynamic Link Weight Configuration
DLWC)算法
该算法的关键在于为链路定义了两个动态权重。在计算工作通道和保护通道时
它能综合解决SRLG限制、动态负载均衡和自陷等3个关键问题。
Abstract
The concept of Shared Risk Link Group(SRLG) is introduced in optical networks
in which the work path and the protection path should be SRLG-disjoint.A novel dynamic shared-path protection algorithm called Dynamic Link Weight Configuration(DLWC) algorithm based on SRLG constraints is proposed.The key to this algorithm is the definition of two dynamic weights of a link
which can be used to synthetically cope with three essential problems
i.e.SRLG constraints
dynamic loading balance and trap in calculating the work path and the protection path.
