Delivering broadband services to fast moving users (e.g. in trains or cars) involves both wired and wireless networks. In this paper, we motivate that a hierarchical Ethernet aggregation network in combination with Ethernet-based access networks is an interesting approach for realizing broadband access to fast moving users. The focus is on the tunnel management in the Ethernet aggregation network for providing broadband services to trains. A hybrid approach is presented, which allows to minimize tunnel setup times and provides accurate tunnel setup triggers. The hybrid approach is described in detail, together with performance measurements on commercially available switches. The achieved tunnel setup times and measured packet loss are presented.
