Path Protection with Pre-identification for MPLS Networks
Dan Wang, Funda Ergün · 2005
Current approaches to providing robust network connections which are tolerant to failures involve restoration schemes which mainly focus on reserving backup paths. In this paper we propose a technique for which avoids the extra cost for reserving, by pre-identifying (but not reserving) the backup paths. We present and analyze an algorithm to solve this problem and study a practical special case in detail. Through simulations we show that our model is significantly more cost-efficient than backup path reservation. We also show how this model can fit into the MPLS architecture
