Abstract

Nowadays, passengers in fast moving vehicles can consume narrow-bandwidth services such as voice telephony or email but there is no widely deployed platform to support broadband multimedia services. In this paper, an aggregation network architecture for the delivery of multimedia services to train passengers is presented. For the topology design and capacity assignment of this network, a novel method is presented that calculates the required dynamic tunnels to meet the traffic demands of the fast moving users while achieving low congestion and optimizing the utilization of the network resources. The method enables that under conditions of train delay the Quality of Service (QoS) requirements of the traffic flows are guaranteed. The capacity assignment efficiency is demonstrated for different network scenarios and due to the time-dependent complexity of the problem, heuristic approaches are designed to solve problems of realistic size.
