摘要： A method forward Ethernet frames at a node in a network supporting an implementation of shortest path bridging (SPB) protocol is disclosed. The method starts with a shortest path computation for the node (referred to as the computing node). The shortest path computation selects at least a shortest path to each destination node in the network, where a neighboring node on the shortest path to reach each node is recorded. Then it computes a downstream loop-free alternate (LFA) node for a destination node, where the LFA node is downstream of the computing node but not on the selected shortest path to the destination node from the computing node. Then when connectivity to the neighboring node on the computed shortest path is detected to be abnormal, the node forwards an Ethernet frame with a destination media access control (MAC) address corresponding to the destination node through the LFA node.

摘要： A method, a mobility node 211 and a new mobility anchor 214b configured to operatively relocate the mobility anchor 214a for a mobile terminal 215a in a wireless communication system 200. The relocation is achieved by a request for redirecting an old bearer B-old configured to communicate user-data between the mobile terminal 215a and an old mobility anchor 214a, and by setting up a new standby bearer B-new configured to operatively communicate user-data between the Mobile Terminal 215a and the new mobility anchor 214b. The standby bearer B-old is ready to be activated once the old bearer B-old is deleted.

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 forthe VPN and populated with local routes for the VPN. A VRF IP loopback address is assigned for the VRF, and a PE IP loopback address is assigned for the ingress PE router. A local route with the VRF and PE IP loopback addresses is then advertised to other PE routers in the backbone network.

摘要： A system and a method are described herein which provide for congestion handling in a packet switched network domain. In case of congestion, overload is measured by a core node, the data packets in proportion to the overload are marked and the signaled overload is stored. At least one egress node 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 where flows are terminated.

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： 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 method is provided of enabling access for a terminal (12-1 ) to a remote network (60) via a mobile network (40). A first connectivity service function (30) is provided as part of the mobile network (40). A second connectivity service function (20) is provided as part of the remote network (60). A third connectivity service function (10) is provided associated with the terminal (12-1). The first connectivity service function (30) is adapted to cooperate in establishing a first layer 2 tunnel (25) between itself (30) and the second connectivity service function (20). The first connectivity service function (30) is also adapted to cooperate in establishing a second layer 2 tunnel (15) between itself (30) and the third connectivity service function (10). The terminal (12-1) thereby has layer 2 access into the remote network (60) through the first and second tunnels (25, 15) using the first, second and third connectivity service functions (30, 20, 10).
