摘要： A method of allowing a nomadic terminal to access a home network on the Layer 2 level. The method comprises connecting said terminal to a remote access network via an access point, the remote access network being connected to an operator's backbone network via a remote access router. Signalling is exchanged between the access point and an authentication server within the backbone network in order to authenticate the terminal to the authentication server and, following successful authentication, a Layer 2 tunnel extending across the backbone network is established for the purpose of connecting said nomadic terminal to the home network.

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.
摘要翻译：描述了一种设置VPN的方法。 VPN设置在具有多个PE路由器的骨干网络中，用于控制到卫星网络中的CE路由器的IP业务的传输。在PE路由器中，为VPN配置VRF，并为VPN填充本地路由。为VPN分配VLAN标识符，并通告给骨干网中的其他PE路由器。或者，VLAN标识符可以由预定的映射算法来确定，所以在所有PE路由器中VPN将是唯一的，在这种情况下，到其他PE路由器的广告可以包含隐式NULL标签。

摘要： Mobility between access domains in an Internet Protocol (IP) network can be supported by introducing a so-called Mobility Manager (MM) that maintains a database of currently attached devices and their current access domain location. The mobility manager may then detect, for a device registered in the database, a change of access domain from a first access domain to a second access domain by monitoring connection maintenance signaling related to the considered device. The mobility manager should at least obtain an indication of such a change of access domain. In response to a detected change of access domain, the mobility manager arranges for a reconfiguration of the network to forward traffic destined to an IP address of the device in the first access domain to a new location in the second access domain. In this way, the mobility manager allows the device to keep its IP address when moving between access domains.

摘要： There is described a method and apparatus for sending data through one or more packet data networks. A stripped-down packet is sent from a packet sending node towards a cache node, the stripped down packet including in its payload a pointer to a payload data segment stored in a file at the cache node. When the stripped-down packet is received at the cache node, the pointer is used to identify the payload data segment from data stored at the cache node. The payload data segment is inserted into the stripped-down packet in place of the pointer so as to generate a full size packet, which is sent from the cache node towards a client.

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.

摘要： Method and apparatus for controlling transmission of data packets in a packet-switched network. When a first end-host (A) sends an address query to a DNS system (300) for a second end-host, the DNS system responds by providing a sender key created from a destination key registered for the second end-host, if the first end-host is authorized to send packets to the second end-host. Thereby, the first end-host, if authorized, is able to get across data packets to the second end-host by attaching a sender tag (TAG) generated from the sender key, as ingress tag to each transmitted data packet. A router (302) in the network matches an ingress tag in a received packet with entries in a forwarding table and sends out the packet on an output port (X) according to a matching entry. Otherwise, the router discards the packet if no matching entry is found in the table.
摘要翻译：用于控制分组交换网络中数据分组传输的方法和装置。当第一终端主机（A）向第二终端主机的DNS系统（300）发送地址查询时，DNS系统通过提供从为第二终端主机注册的目的地密钥创建的发送者密钥进行响应，如果第一个终端主机被授权将数据包发送到第二个终端主机。因此，如果授权，第一终端主机能够通过将从发送方密钥生成的发送者标签（TAG）作为入口标签附加到每个发送的数据分组，来跨越数据分组到达第二终端主机。网络中的路由器（302）将接收到的分组中的入口标签与转发表中的条目匹配，并根据匹配条目在输出端口（X）上发送分组。否则，如果表中没有匹配的条目，路由器将丢弃该数据包。
