Abstract:
Systems, methods, and instrumentalities are disclosed for defining a network specialization mechanism that enables a better alignment between end users' usage profiles and their access networks. Conteni specialization of networks may be implemented as a preference o a particular SCN or network in terms of content. Such a network may, for example, cache in priority preferred content, provide preferential quality of service (QoS), or limit access to non-preferred content. A network may advertise its preference or content specialization to end users (e.g., so that end users can decide to attach to SCNs or networks with compatible preferences) and to other content networks (e.g., to influence content routing decisions or to negotiate partitioning of the specialization space). Such content specialization may apply to physical or virtual networks.
Abstract:
Methods and apparatus are described for synchronizing a media presentation on a plurality of wireless transmit/receive units (WTRUs). A media session may be synchronized by a first wireless transmit/receive unit (WTRU) creating a networked bookmark for a media program at a bookmark-created time; the first WTRU presenting the media program at a bookmark-presentation time, wherein the first WTRU includes in the networked bookmark a suggested presentation offset that indicates an offset in time from the bookmark-created time to the bookmark-presentation time; and the first WTRU transmitting the networked bookmark, including the suggested presentation offset, to an Internet Protocol (IP) Multimedia Subsystem (IMS) network for use by a second WTRU in replicating, at the second WTRU, the presentation of the media program at the first WTRU.
Abstract:
The disclosure pertains to CDNI interconnection at a global level. CDNXs are enhanced to provide logging services associated with bilateral or multilateral agreement with CDNs, where these CDNs are interconnected with other CDNs not using the same CDNX. Moreover, additional functions are added in CDNXs and CDN Interconnection protocols to support CDN capability advertisement, CDN peer discovery, and to bootstrap CDN Interconnection.
Abstract:
A method and apparatus for content identification, retrieval, and routing in the Internet are provided. In the method and apparatus, content is uniquely identified using an object identifier (OID), and the OID is used for routing and retrieving content in an Internet network. Further, in the method and apparatus, OID summarization based on one or more OIDs may be performed, in which Bloom filters are applied to a portion of the one or more OIDs. Furthermore, hash functions may be applied to network node identities to determine location resolver nodes associated with content.
Abstract:
Methods and apparatus are described for synchronizing a media presentation on a plurality of wireless transmit/receive units (WTRUs). A media session may be replicated from a first WTRU onto a second WTRU. The first WTRU may initiate a bookmark procedure to create a bookmark to obtain synchronized playout with the second WTRU. A suggested presentation offset in the bookmark may specify an offset in time from a bookmark created time to a bookmark presentation time at the first WTRU. The first WTRU may establish an Internet protocol (IP) multimedia subsystem (IMS) session with a packet switch stream (PSS) server. The media session may be replicated onto the second WTRU at a wall-clock time T, and the second WTRU may present an offset equal to T−bookmarkcreatedtime+bookmark offset−suggestedPresentationOffset from the beginning of a program in order to obtain synchronized media playout with the first WTRU.
Abstract:
A method and apparatus are described for forwarding content delivery network interconnection (CDNI) signaling. A CDNI router content delivery network (CDN) may establish CDNIs with upstream and downstream CDNs. The CDNI router CDN may receive a CDNI route advertisement message from at least one of the upstream and downstream CDNs. The CDNI router CDN may update at least one end-user-based CDNI routing table based on Internet protocol (IP) address blocks in the CDNI route advertisement message. The CDNI router CDN may transmit an updated CDNI route advertisement message to at least one of the upstream and downstream CDNs. At least one of the upstream and downstream CDNs may update at least one end-user-based CDNI routing table based on the end user IP address blocks in the updated CDNI route advertisement message.
Abstract:
A multi-hypothesis rate adaptation technique may be performed for one or more wireless multimedia streaming scenarios. Managing a multimedia streaming session may involve sending, by a client, a request for a first portion of content to a server. A response may be received from a proxy. The response may comprise the first portion of content and information associated with a second portion of content available via the proxy. A request may be sent to the proxy for the proxy to deliver the second portion of content to the client. A change in a parameter associated with the multimedia streaming session may be determined based on data received from the proxy. It may be determined to change a rate adaptation. A Wireless Transmit/Receive Unit (WTRU) may be configured to perform the rate adaptation.
Abstract:
Disclosed herein are methods and systems for integrating peer-to-peer (P2P) networks with content delivery networks (CDNs). In an embodiment, a method for use in a network storage control peer (NSCP) supporting P2P operation includes receiving swarm stats from a tracker; determining, based on the received swarm stats, a P2P rarity associated with a content piece; and responsive to the determined P2P rarity, transmitting an upload request message to an ingestion gateway, wherein the upload request message indicates that the content piece is to be uploaded to a CDN.
Abstract:
An apparatus and method are described for sponsoring service and preferential traffic handling, (i.e., data connectivity) by wireless transmit/receive units (WTRUs). A first WTRU may initiate user sponsoring of a second WTRU via an application server (AS). The first WTRU may receive a service trigger from the AS and forward the service trigger to the second WTRU. The second WTRU may then initiate a sponsored session with the AS using the service trigger in order to receive a service from the AS. The first WTRU may also request the AS to transfer a credit to the second WTRU. The AS may establish a direct communication link with a charging system including an online charging function (OCF) and a charging data function (CDF). The AS may send a request to a network to provide preferential traffic handling needed to deliver content to the second WTRU.
Abstract:
Techniques for inter-user equipment (UE) transfer (IUT) are disclosed. An application server may receive an IUT request for transfer of a media session toward at least one initial UE such that the media session is to be played by at least two target UEs. The server may determine eligibility for IUT with group synchronization based on the request. The server may send a message to the initial UE that IUT with group synchronization is not allowed on a condition that IUT with group synchronization is not allowed. Further, the server may trigger inter-destination media synchronization (IDMS) for group synchronization of media sessions among the UEs on a condition that IUT with group synchronization is allowed. The media sessions may include a first media session and second media session. The media stream may be played by at least two UEs that are geographically separated after the transfer.
