摘要： According to a first aspect of the present invention there is provided a method of selecting a data source node from a plurality of data source nodes, the selected data source node being used to send data to a data requesting node over a packet data network. The method comprises, at an intermediate node of the network, intercepting at least one message sent to or from said data requesting node (S1), the message(s) relating to data source node suitability, determining a cost of communication between said data requesting node and the or each data source node to which said message(s) relate (S4, S7), and influencing data source node suitability information sent to said data requesting node (S5, S8) to take account of said cost(s) to enable said data requesting node to use the information to select a data source node.

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).

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： 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： There is provided a method for use by a first processing unit in or to be installed in a router. The first processing unit is configured or responsible for routing (or forwarding) packets to and from other routers. There may be other such first processing units in or installed in the router. In a first step (S1), information is received at the first processing unit which requires dissemination to other routers. The information also requires processing to determine what, if any, reconfiguration of the routing (forwarding) performed by the first processing unit is required. I n a second step (S2 b) the information is forwarded in a packet to other routers as required according to the routing (forwarding) configuration for the first processing unit. In a third step (S2c) the information is forwarded to at least one other first processing unit in the router (if there are any other first processing units in the router) not already in receipt of the information. If an expedited dissemination procedure is required, the second and third steps (S2b, S2c) are performed before the processing (to determine what if any reconfiguration is required) has been performed (completed) and/or before the first processing unit has been informed of the result of such processing and/or before any reconfiguration required in the first processing unit has been requested, arranged or performed (completed).

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.
