摘要： The system includes a mobile node (101) communicating with a correspondent node (102), a home agent node (131) managing the mobile node (101), a proxy node (121) being located closer to the mobile node (101) than the home agent node (131) and relaying the packets from the mobile node (101) to the home agent node (131), and a routing manager (141) managing a route of the packets. The proxy node (121) detects a trigger of a packet route optimization and notifies the routing manager (141). The proxy node (121) establishes the optimized routing path according to a command received from the routing manager (141) and routes the packets through the established routing path using a secure method.

摘要： There are provided a scalable method for mobility management applied to an IP-based network system including a plurality of routers and a plurality of servers, a part of which serve as a home routing manager (HRM), a part of which serve as local routing managers (LRM) for individual mobile nodes. The method at least comprises the steps of sending a first query about a routing address of a destination mobile node toward the HRM, based on an activation notification (AN) from an ingress access router (AR) of the plurality of routers, triggered by a source mobile mode, from an LRM receiving the activation notification; relaying the first query via one or more intermediate routing managers (IRM) closer to the HRM until the first query reaches the HRM; and in response to the first query, sending the routing address of the destination mobile node back to the ingress access router through the relay path from the HRM.

摘要： There are provided a method, a network system, and a router capable of decreasing the chance of VRM or VLM changes so as to reduce signaling, and consequently contributing to better scalability. The method is applied to mobility management used in an IP-based network system, which contains a plurality of access routers (AR), location managers (LM) and routing managers (RM), through which a mobile node (MN) transmits and receives information. According to the method, a visited routing manager (VRM) where the MN is currently located monitors the MN, an AR currently communicating with the MN discriminates whether or not the MN is moving out of its connectivity range, and the VRM discriminates whether or not the MN is moving out of its control range. Then, the method switches mobility management over from the current AR to a new AR in accordance with the discrimination results, and switches mobility management over from the current VRM to a new VRM in accordance with the discrimination result.

摘要： The present disclosure relates to forwarding of network traffic. In one of its aspects, the technology presented herein concerns a method for forwarding network traffic from multiple sources to multiple destinations on maximally disjoint paths by maximally redundant trees, M RTs. The method is implemented in a network clement implementing multipoint-to-multipoint functionalities in a path computation element, PCE, of a network, wherein the network comprise* a plurality of network elements. According to the method, an almost directed acyclic graph, A DAG, is computed for the network. Next hops along MRTs are computed by using the A DAG. One or more valid path pair(s) of the computed MRTs that is/are disjoint is/are determined and then, the network traffic is forwarded by using the valid path pair(s) of the MRT(s).
