Most of previous research on survivable networks has been related to unicast communications. In this paper we propose a new approach to network survivability of anycast communications. To the best of our knowledge, anycast defined as one-to-one-of-many technique has not received much attention recently. To provide network survivability, we use the single backup path approach, i.e. each demand has...
This work focuses on the problem of survivable network design with simultaneous unicast and anycast flows. The motivation for this problem is twofold. First, in recent years we can observe an increasing popularity of network services using anycast flows (e.g. content delivery networks (CDN), domain name service (DNS), peer-to-peer (P2P)) systems. Second, current users require reliable network services,...
Most of previous research in anycasting has been focused on best-effort networks and IP networks. In contrast, we propose a QoS-based routing of anycast demands in connection-oriented MPLS network. Since in real networks different kinds of flows are transmitted over the same links, we assume that both unicast and anycast requests must be served in the network. Survivability of the network is one of...
