Management of aggregation networks for broadband Internet access in fast moving trains

Current satellite, GPRS and GSM systems lack from different shortcomings to provide broadband Internet access to fast moving trains. In this paper, we motivate that an Ethernet based aggregation network architecture is the best approach for realizing broadband Internet access in trains. The focus is on the management system for the Ethernet aggregation network and more specifically on the implementation of the management module for tunnel switching trigger management. The components of the management system are presented and three mechanisms for the implementation of the tunnel switching trigger management are detailed: a prediction based, a signaling based and a location aware approach. The different mechanisms are compared with respect to availability, complexity and network usage.
