报告摘要：Kwong et al. (2011) proposed a reactive routing scheme using the multi-paths technique for integrating two mechanisms of route discovery and route maintenance in intra-domain IP networks. They further defined a route to be a protection routing if there is a loop-free alternate path for packet forwarding when a single failed component (including link or node) occurs. Later on, Tapolcai (2013) showed that a network possessing two completely independent spanning trees (CISTs for short) suffices to configure a protection routing. A set of k (k>1) spanning trees in a network is called CISTs if they are pairwise edge-disjoint and inner-node-disjoint. Particularly, if k=2, such a set of CISTs is called a dual-CIST. In the early stage, Hasunuma (2002) already pointed out that the problem of determining whether there exists a dual-CIST in a graph is NP-complete. This talk includes the following topics:
(1) We show how to construct three CISTs in a network with connectivity at most 6 by a two-stages tree-searching algorithm. In particular, we demonstrate the case in a kind of hypercube-variant networks, called crossed cubes.
(2) We show how to configure a routing scheme called secure-protection routing as an application of CISTs such that the routing is not only protected but also secure (i.e., no other node except the destination in the network can receive the complete message).
(3) We provide simulation results to show the performance evaluation of the proposed routing.
