On the Design of Aggregation Networks for Fast Moving Users

摘要

In this paper, the focus is on the enabling platform for delivery of multimedia services to fast moving users (e.g., users in trains or cars). Moreover, a study on the aggregation part of this platform is presented. This aggregation network preserves the connection between the service provider domain and the access networks. The fast moving users are connected to the access network via a wireless connection. In the aggregation part of the architecture, users are taken together into tunnels, and as these users move from access network to another access network, tunnels have to move with them. It has already been proven that a dynamic tunnel management system radically reduces the network cost This paper investigates the possibilities of splitting the big tunnel of each train into several smaller ones and shows that there is a optimal value for the number of tunnels.
