    摘要: A method for setting up a VPN is described. The VPN is set up in a backbone network having a plurality of PE routers for controlling the transfer of IP traffic to and from CE routers in satellite networks. In a PE router, a VRF is configured for the VPN and populated with local routes for the VPN. A VLAN identifier is assigned for the VPN, and advertised to other PE routers in the backbone network. Alternatively, the VLAN identifier may be determined by a predetermined mapping algorithm so it will be unique to the VPN in all PE routers, in which case the advertisement to other PE routers may contain an implicit NULL label.

    摘要: In an access network, a tunnel gateway (TGW) managed network caching architecture is proposed. The proposed TGW receives a terminal request directed to a data server for a flow of data. The terminal request is forwarded to the TGW through a tunnel from a tunnel endpoint located below the TGW. The TGW selects a network cache to handle the data traffic of the flow requested by the requesting terminal. The TGW then redirects the terminal request to the selected network cache to provide the requested service. The TGW redirects the terminal request through a tunnel whose endpoint is the selected network cache.
