摘要： Method and apparatus for supporting the forwarding of received data packets in a router (402,702) of a packet- switched network. A forwarding table (706a) is configured in the router based on aggregating router keys and associated aggregation related instructions received from a key manager (400,700). Each aggregating router key represents a set of destinations. When a data packet (P) is received comprising an ingress tag derived from a sender key or router key, the ingress tag is matched with entries in the forwarding table. An outgoing port is selected for the packet according to a found matching table entry that further comprises an associated aggregation related instruction. An egress tag is then created according to the aggregation related instruction, and the packet with the created egress tag attached is sent from the selected outgoing port to a next hop router.

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 authorised to send packets to the second end-host. Thereby, the first end- host, if authorised, 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，如果被授权，则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。

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： A system a core (104), an edge node (102, 103) and a method are provided for congestion handling in a packet switched network domain. In case of congestion overload is measured, the data packets in proportion to the overload are marked and the signaled overload is stored. At least one egress node (103) receives marked and not marked packets, decodes and counts the overload from the marked packets in a counting interval. Congestion report messages are sent to ingress nodes (102) where flows are terminated. A core node (104) comprises a storage means (314) taking into account the previously signaled overload, which are already being handled in a congestion handling control loop. An edge node (103) comprises means for adding new flows to the set of affected flows, means for identifying affected flows to be terminated so that the number of identified affected flows should generate together traffic equal to the overload, and means for removing flows to be terminated from set of affected flows. In an advantageous embodiment the market module (315) applies a hysteresis algorithm with a higher bound used to detect congestion and to trigger the marking of user data packets in proportion to the measured overload, and a lower bound used as the reference to measure the overload ratio.

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： Method and apparatus for controlling the routing of data packets in an IP network (200). A DNS system (202) stores a packet admission policy configured for a first end- host (B) that dictates conditions for allowing other end- hosts to get across data packets to the first end-host or not. A routing voucher is defined which is required for routing data packets to the first end-host. The routing voucher is distributed to routers (R) in the IP network. When an address query is received at the DNS system (202) from a second end-host, the voucher is supplied to the second end-host if the configured policy allows the second end-host to convey data packets. Otherwise, the voucher is not supplied. If allowed, the second end-host will add the routing voucher to any data packets directed to the first end-host. When a valid routing voucher is present in a packet at a router (204) in the network, the packet will be forwarded to the next router in the IP network. The router will otherwise discard the packet.

摘要： There is provided a method for use by a router in a communications network. Forwarding information is maintained (S1) which specifies the next hop node for each of a plurality of possible destination nodes. Update information is maintained (S1) which specifies how, if at all, the next hop nodes specified in the forwarding information are to be updated for a plurality of possible network resource failures. Known failure information is maintained (S1) which relates to a known network resource failure or which specifies that there is no known network resource failure. A failure notification is received (S2) relating to a network resource failure. In response to receipt of the failure notification, it is determined (S3) from the failure notification how, if at all, the known failure information is to be updated, and the known failure information is updated, if required, based on the determination (S4). A communications packet is received (S5). Various steps (S6 to S10) are carried out in response to receipt of the communications packet. The destination node for the received packet is determined (S6). It is determined (S7) whether the next hop node specified by the forwarding information for the determined destination node is potentially invalid in view of the known failure information. If so, then the next hop node for the determined destination node is updated if necessary in the forwarding information using the update information and the known failure information (S8). The next hop node is determined for the received packet using the forwarding information and the determined destination node (S9). The received packet is forwarded towards the determined next hop node (S10).
