Tunnel set-up mechanisms in Ethernet networks for fast moving users

This paper describes the design of a novel tunnel set-up mechanism for Ethernet networks that allows users in fast moving vehicles to access multimedia services. The network architecture under study will be presented and the designed tunnel set-up mechanisms will be detailed. For the establishment of VLAN-based tunnels, a "scoped refresh" extension of the GVRP standard has been implemented. For the distribution of QoS-related reservation parameters, a new GARP-based protocol (G2RP) is developed with closed loop design, a mechanism for updating reservation parameters and admission control. Both protocols are implemented on a Linux test bed using the click modular router. Two important scenarios will be detailed, together with an overview of the performance evaluation results.
