In a method for managing transmission of data files to users, a first file is divided into a plurality of first segments and a second file is divided into a plurality of second segments. A first segment is sent to a first user and a different first segment is sent to a second user. A second segment is sent to the first user and a different second segment is sent to the second user. At least part of a segment sent to the first user is combined with at least part of a segment sent to the second user to produce a combined segment which is of smaller size than the total size of the at least parts of segments before combining. The combined segment is transmitted to the first user and to the second user for each user to recover a segment using the combined segment and at least part of a segment.

A method and an apparatus for implementing a storage function in a passive optical network (PON) system. On the basis of a LINK ID held by the data, data requiring storage, e.g. data making exclusive use of a wide bandwidth such as audiovisual data and large-volume data packages, are determined among all the data sent to an optical network unit. These data requiring storage are stored in a storage device installed in the optical network unit. In case the user requests data stored in the storage device, the stored data are transferred directly to the user, without any need to request and send these data for the second time via an IPTV server and the core network. It is possible to avoid duplicate transfers of data, and in particular to avoid duplicate transfers of data making exclusive use of a comparatively wide bandwidth such as audiovisual data and large-volume data packages, to improve the utilization factor of the downlink bandwidth, and to reduce flow congestion and data delays.

A process for communicating utility-related data over at least one network is described. the process includes: collecting utility-related data at a hub device during a first predetermined period of time; securing the utility-related data at the hub device using digital envelopes during the first predetermined period of time; initiating by the hub device an autonomous wake up process during a second predetermined period of time; sending the secure utility-related data over a first network to a designated server via at least one User Datagram protocol (“UDP”) message during the second predetermined period of time; and receiving an acknowledgement of receipt message of the at least one UDP message from the designated server; wherein the first and second predetermined periods of time typically do not overlap, but may overlap.

A method for identification of popular content provided over a first portion of a network to a second portion of a network in the form of packets containing, the method comprises identifying a source of content in the first portion of a network. Deep-packet-inspection (DPI) is performed to determine if content in each packet related to the content is to be stored in a storage that is in a path between the content source and at least a user node in the second portion of the network. The content is stored. A request is received from the user node for a requested content. It is determined if the requested content or portions of the requested content is in the storage. if the requested content or portions of the requested content is missing in the storage, a request is sent to the content source for the requested content or missing portions of the requested content.

An application service includes a device interface manager, an acquisition manager, and a job manager. The device interface is configured to receive, from a device, a print instruction defining a context. The acquisition manager is configured to use the context to acquire context compatible content. The job manager is configured to communicate a reference to a print service for accessing cached context compatible print data for the print instruction if the context compatible print data is available in a cache, and to otherwise communicate to the print service, context compatible print data for context compatible content acquired by the acquisition manager.

A P2P based method for playing media is provided. The method includes logging in a network; selecting a live broadcasting service or a video-on-demand service, and receiving a judgment result on whether to buffer a data flow corresponding to the live broadcasting service or the video-on-demand service; obtaining the corresponding data flow according to a selection result, and buffering the data flow when the judgment result is yes; and providing the buffered corresponding data flow for a video-on-demand node or a live broadcasting node as a data source of the live broadcasting service or the video-on-demand service.

A teleconferencing system receives at least two streams that are parts of a live conference and individually records at least one of the streams. During the conference, a conferencing system receives a request from a communication device that is participating in the conference for at least a portion of at least one but not all of the recorded streams and in response sends the requested portion(s) of the stream to the communication device. The communication device can then play back the requested portion(s) of the recorded stream(s) to a participant in the conference. The streams may be audio and/or video streams.
摘要:
In an IPTV network, one or more caches may be provided at the network nodes for storing video content in order to reduce bandwidth requirements. Cache functions such as cache effectiveness and cacheability may be defined and optimized to determine optimal partitioning of cache memory for caching the unicast services of the IPTV network.

A method and apparatus for managing sessions by a load balancer using a session affinity cache to manage common session identifiers and resource node session identifiers. A session affinity manager within the load balancer utilizes a common session identifier to represent multiple sessions to a client. The session affinity manager provided generates a common session identifier for a set of resource node sessions for each client. The relationship between the resource node session identifiers and common session identifier is maintained in the session affinity cache by the session affinity manager. The session affinity manager translates client requests using the common session identifier into requests using the resource node session identifier retrieved from the session affinity cache. The session affinity manager rewrites resource node responses to use a common session identifier in place of resource node session identifiers.

The present invention provides a solution for sharing server generated output to satisfy requests for content originated by different clients. More specifically, a server side resource can analyze a content request and compare this request to a set of active request handling operations. When one of the active operations is capable of satisfying a discrete portion of the content request, an association can be established between the active operation and the content request. When the active operation produces results, these results are returned to satisfy a request of an original client as well as to satisfy a request of a client that issued the content request. The solution can be implemented in a variety of environments, including one where asynchronous server-side operations are conducted by different server-side resources for a single request context.
