Today's converged networks are mainly characterized by their support of real-time and high priority traffic requiring a certain level of quality of service (QoS). In this context, traffic classification and prioritization are key features in providing preferential treatments of the traffic in the core of the network. In this paper, we address the joint problem of path allocation and admission control...
Capacity limitation is one of the fundamental issues in wireless mesh networks. The aggregate capacity can be increased by equipping each mesh router with multiple radios tuned into distinct frequency channels. However, most past research efforts that attempt to exploit multiple channels assume orthogonal channels of fixed pre-determined width, which prohibits the further effective use of spectrum...
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....
