在这项研究中，我们研究了一种经济有效的方法来保护多个组播会话免受光网络中任何链路故障的影响。该方法被称为交叉共享，在几个多播会话之间提供了备份资源的最佳共享。我们的交叉共享方法采用了针对多播会话进行了修改的链路向量模型，并且相对于弧形不相交和自共享方法，尤其是对于大量会话，提供了显著的备份资源节约(对于小型六节点网络为48%，对于大型全国性网络为39%)。
In this study, we investigate a cost-effective approach for protecting several multicast sessions from any link failure in an optical network. The approach, referred to as cross-sharing, provides an optimal sharing of backup resources among several multicast sessions. Our cross-sharing approach employs the link-vector model, modified for multicast sessions, and provides significant cost savings (48% for a small six-node network and 39% for a large nationwide network) of backup resources relative to arc-disjoint and self-sharing approaches, especially for a large number of sessions.
