Managing ethernet aggregation networks for fast moving users

Delivering broadband services to fast moving users (e.g., in trains) involves both wired and wireless networks. In this article we demonstrate that a hierarchical wired Ethernet aggregation network in combination with Ethernet-based wireless access networks is an interesting approach for realizing broadband access to fast moving users. The focus of the article is on fast and autonomic setup and removal of tunnels in the Ethernet aggregation network for providing broadband services to trains. The resulting moving tunnels realize seamless connectivity for the users on a train with an efficient resource reservation in the aggregation network. A hybrid approach is presented, which allows tunnel-setup times to be minimized and provides accurate tunnel-setup triggers. A testbed has been set up to evaluate the hybrid approach and the results of this work are intended to be used as a guideline for network service providers on how to set up an Ethernet-based aggregation network for fast moving, users.
