Methods and apparatus for supporting a Mobile IP mobile router are disclosed. A method of establishing a multicast session, thereby enabling multicast IP data packets to be transmitted to the multicast mobile router, include registering the mobile router with its Home Agent. Upon receipt of a registration reply from the Home Agent, the mobile router sends a join host group message.

An object is, when a mobile terminal performs a handover, to more quickly reset a path after the handover and reduce interrupt time (particularly interrupt time of a QoS path) of packet communication. For example, in a state in which a MN 101 has not acquired an address (NCoA) of a new connection destination (AR 109), the MN 101 requests that a QNE (proxy) 123 start a process of establishing a QoS path used when the MN 101 is connected to a new connection destination. The QNE (proxy) makes a resource reservation between the ONE (proxy) itself and a CN 121. As a result, in an upper stream above a QNE (CRN 115), new path information (filter B) is correlated with path information (filter A) used when the MN is connected to an AR 105. Until when the MN uses the actual new CoA and updates the QoS path after movement, the data packet is encapsulated by a proxy node and transmitted based on the path information (filter B).

A technique computes a traffic engineering (TE) label switched path (LSP) that spans multiple domains of a computer network from a head-end node of a local domain to a tail-end node of a remote domain. The novel inter-domain TE-LSP computation technique comprises a computation algorithm executed by the head-end node, which utilizes Path Computation Elements (PCEs) located within the remote domains (i.e., other than the local domain). Specifically, the head-end node requests path segments from a PCE in each of the remote domains, in which the path segments represent paths between all entry border routers to either all exit border routers of the particular remote domain (i.e., through the domain), or to the tail-end node. Upon receiving path segments from each remote domain, the head-end node combines the path segments with local domain information, and performs a forward path computation from the head-end node to the tail-end node to find the best (i.e., “shortest”) path.
