Abstract: A method comprises associating at least one cache replacement granularity value with a given one of a plurality of content streams comprising a number of segments, receiving a request for a given segment of the given content stream in a network element, identifying a given portion of the given content stream which contains the given segment, updating a value corresponding to the given portion of the given content stream, and determining whether to store the given portion of the given content stream in a memory of the network element based at least in part on the updated value corresponding to the given portion. The at least one cache replacement granularity value represents a given number of segments, the given content stream being separable into one or more portions based at least in part on the at least one cache replacement granularity value.

Abstract: A method of allocating resources for transmitting content from a network element in a communications network to one or more mobile devices each in communication with the network element may include receiving, at the network element, characteristic information corresponding to each of the one or more mobile devices; and generating one or more adaptive guaranteed bit rate (AGBR) values at the network element corresponding to each of the one or more mobile devices, respectively. The AGBR values may be GBR values generated for each of the one or more mobile devices based on the corresponding characteristic information. A first scheduling algorithm may be executed at the network element based on the one or more AGBR values; and resources may be allocated to the one or more mobile devices based on an output of the scheduling algorithm.

Abstract: A method include receiving, at a first cache device, a request to send a first asset to a second device; determining whether the first asset is stored at the first cache device; when the determining whether the first asset is stored at the first cache device indicates that first asset is not stored at the first cache device, obtaining, at the first cache device, the first asset, performing a comparison operation based on an average inter-arrival time of the first asset with respect to the first cache device and a characteristic time of the first cache device, the characteristic time of the first cache device being an average period of time assets cached at the first cache device are cached before being evicted from the first cache device, and determining whether or not to cache the obtained first asset at the first cache device based on the comparison; and sending the obtained first asset to the second device.

Abstract: The present invention supports services that span multiple service domains. In one embodiment, the present invention provides service-level interaction between an enterprise network and a non-enterprise network (or networks), thereby enabling enterprise users at remote locations (i.e., at home, on vacation, or at other locations remote from the enterprise location) to use services typically only available to the enterprise users while at the enterprise location (e.g., while in the office). The present invention provides a calendar notification service, whereby a calendar notification originating in an enterprise network is provided to a remote enterprise user via a non-enterprise network. The present invention provides an enterprise dialing plan service, whereby a remote enterprise user may register a remote user device to be able to use an enterprise dialing plan.

Abstract: The method includes retrieving subscriber and device information based on an application identifier and a GBR request indication, sending a message to a network entity, the message including a Quality of Service (QoS) Class Identifier (QCI), the QCI indicating an AGBR bearer is to be used for delivering content to a mobile unit, generating an AGBR bearer based on the QCI and a GBR setting and associating the content with the AGBR bearer. The method includes sending a message and the content to a network entity, the message including the QCI, scheduling the mobile unit on the AGBR bearer based on the QCI and communicating the content to the mobile unit based on the schedule.

Abstract: A method comprises receiving a first request for a first segment of a content stream in a network element from a given one of a plurality of clients, determining in the network element whether the first segment is stored in a memory of the network element, sending a second request for the first segment from the network element to a server responsive to the determining step, receiving a response comprising the first segment in the network element from the server responsive to the second request, and sending the first segment from the network element to the given one of the plurality of clients. The first segment is related to a second segment of the content stream, the relationship being transparent to the network element but being inferable based at least in part on at least one of the first request, the response and one or more prior requests.

Abstract: A chunk request scheduler is provided for HTTP adaptive streaming. Requests for media chunks are scheduled over a network by requesting the media chunks over at least one connection; storing the media chunks in at least one buffer; monitoring a level of the at least one buffer; and selectively switching between at least two predefined download strategies for the request based on the buffer level. Requests for media chunks can also be scheduled over a network by obtaining an ordering of the connections based on a rate of each connection; storing the media chunks in at least one buffer; and requesting the media chunks over the ordered plurality of connections based on a size of the media chunks. For example, audio chunk requests can be scheduled over TCP connections having a lower rate order and video chunk requests can be scheduled over TCP connections having a higher rate order.

Abstract: A content distribution network (CDN) comprising a hierarchy of content storage nodes (CSNs) or caches having storage space that is allocated between local space for storing locally popular content objects and federated space for storing a portion of the less popular content objects. Local space and federated space based upon changes in content object popularity and/or other utility factors. Optionally, parent/child (upstream/downstream) communication paths are used to migrate content between CSNs or caches of the same or different hierarchical levels to avoid utilizing higher price top hierarchical level communications channels.

Abstract: A method and communication network for providing a subscriber with a blend of services of the communication network delivered to the subscriber through a telephone and services delivered to the subscriber through a TV delivery system in communication with the network. Upon receipt of a message from a calling party, a service broker function may be configured to execute service package information associated with services of the TV delivery system subscription to include obtaining and delivering caller ID information of the calling party. The service broker function may be configured to alter the message request to generate a modified message request in respect to information affecting alerting of the subscriber's phone. The modified message is sent to the subscriber's phone so that, while information of the calling party is displayed on the TV delivery system, alerting of the phone is modified.

Abstract: When an intelligent VoIP endpoint terminal on a VoIP network becomes inoperative for any reason and can't respond to a service request that it had been programmed for, rather than leaving that service request unfulfilled, a VoIP network-hosted instance of that primarily endpoint terminal-provided service is invoked to handle that request and provide the service that would have otherwise been provided by the endpoint terminal. The network-hosted instance thus executes the requested service on behalf of the unavailable endpoint terminal.
