In this paper, a practical routing protocol that maximizes the guaranteed node traffic loads in reliable networks is designed and analyzed. The derived node traffic loads can be routed for every traffic pattern, and regardless of the possible single node or link failures. First, it is described how load balanced shortest path routing (LB-SPR) can be optimized to maximize the value of the guaranteed...
The paper describes an optimization model which aims at minimizing the maximum link utilization of IP telecommunication networks under the joint use of the traditional IGP protocols and the more sophisticated MPLS-TE technology. The survivability of the network is taken into account in the optimization process implementing the path restoration scheme. This scheme benefits of the Fast Re-Route (FRR)...
Traffic grooming techniques in optical networks are attracting increasing research attention in order to handle the huge bandwidth mismatch between high capacity lightpaths and low-rate individual traffic requests. It is important to have guaranteed survivability of all user connections in such networks. Path protection has emerged as a widely accepted technique for survivable WDM network design....
