Abstract
Recovering from node failures is generally much more complicated than link recovery. Node failures have not been given much attention in the literature and the characteristics need to be studied carefully. In this paper, we examine and quantify the effectiveness of protection schemes in terms of their ability to handle node failures. We also investigate protection algorithms’ ability to recover from multiple failures of links and nodes, extending the study of multiple link failures in1 by introducing a more complicated failure model. We investigate issues that did not exist for failure models that deal with only link failures. The tradeoff between capacity efficiency and robustness to multiple failures is demonstrated.
