    摘要： Embodiments contemplate the movement of mobile node (MN) from a first access network to a second access network, while in communication with a CDN server (e.g. a surrogate providing a multimedia streaming session). The server selection may become sub- optimal as a result of this movement. A first CDN may learn about MN mobility event via the MN, an access network node, the server, or another node. The first CDN may trigger reselection by upstream CDN by sending a CDNI reselection request message, including information for the upstream CDN to perform request routing for the MN with the specified content, at a different location. The upstream CDN may perform the request routing procedure. The upstream CDN may return the request routing result to first CDN. The initial server may send a redirection message back to the application, which may interpret the message and continue streaming from a different server.

    摘要： Methods, apparatus, systems, devices, and computer program products directed to enabling federation 200 of multiple independent networks 204A, 204B, 204C, 204D through hash-routing based peering (HRP) and/or summary-routing based peering (SRP) are provided. Pursuant to new methodologies and/or technologies provided herein the multiple independent networks self-organize, or otherwise assemble, as a federation of network peers. The network peers 204A, 204B, 204C, 204D cooperate to pool and/or merge resources to make available for the federation 200 a population of content objects. As members of the federation, each of the network peers undertakes responsibility for making available to other network peers a share of the population. The multiple independent networks establish connectivity and federate using an HRP protocol. Pursuant to the HRP protocol, the network peers allocate amongst themselves respective key ranges within a hash-value space of a hash function. The network peers employ an allocation strategy to guide allocation of the hash-value space. When one of the network peers 204C receives a content request 201 from a local end user 202, local router or another network, the network peer routes and/or forwards the content request over a backhaul or transit network 216C or any link not part of the peering network if the content request falls into the content-object population allocated to this peer. Alternatively, the network peer routes and/or forwards the content request 201 through another network peer for processing if a hash value calculated from the content request falls within a key range of a hash value space allocated to such network peer. Logically merging the multiple individual networks as a federation with the logically combined backhaul and/or caching resources of the network peers 204A, 204B, 204C, 204D, should result in an efficiency gain because of a higher cache-hit ratio, since the merged caching resources supports a larger population. Federating the multiple individual networks using the HRP protocol enables such logical merging of caching storage capacity and transit (or backhaul) transfer capacity of the multiple individual networks.

    摘要： A method and apparatus are described for synchronizing mobile station (i.e., wireless transmit/receive unit (WTRU)) media flows during a collaboration session. Inter-WTRU transfer request messages, flow addition request messages and session update request messages may be exchanged between a plurality of WTRUs and a session continuity control application server (SCC-AS). Each of the messages may include a session description protocol (SDP) attribute line containing time synchronization information (e.g., a presentation time offset (PTO) information element (IE), a media flow group identity (ID) and a synchronization tolerance IE). The SCC-AS may update the time synchronization information and include the updated information in messages it sends to the WTRUs, which may re-synchronize their respective media flows based on the updated time synchronization information.
