Abstract:
There is described a method for determining a play duration estimate of an adaptive bit rate (ABR) media presentation. The method comprises receiving at a network entity a media playlist manifest file of the media presentation, wherein the manifest file is transmitted from a content server to a client and comprises a plurality of entries, each entry linking to a respective different one of a plurality of media segments of the media presentation. The method further comprises determining a data size of the manifest file; and determining a play duration estimate of the media presentation based on the determined data size of the manifest file, a first value that represents a data size of each of the plurality of entries in the manifest file and a second value that represents a play duration of each media segment of the plurality of media segments of the media presentation.
Abstract:
A network device transparently intercepts HTTP transmissions between a user device and a web server. The network device stores user preference information, which allows the intermediate network device to apply the user preference information to retrieved content that is directed to the user's mobile device.
Abstract:
There is described an apparatus for a base station in a radio access network. The apparatus is configured to detect a change in a radio network congestion status associated with a cell or cell sector of the base station that is being used to serve a mobile device, the change being a change to a given one of a plurality of possible radio congestion levels. The apparatus starts a packet modification process to modify one or more packets in each of one or more uplink data flows from the mobile device to a core network of the radio access network, the one or more packets in each of the one or more uplink data flows being modified by the packet modification process to signal, to a server in the core network, the change in congestion status to the given one of the plurality of possible radio congestion levels.
Abstract:
A method, apparatus and computer program product for maintaining a connection cache at an intermediate server, wherein the connection cache relating to resource requests from a plurality of devices to a plurality of servers remote therefrom. The method comprises monitoring resource requests addressed to a plurality of said remote servers during a first time period; generating statistics data on the basis of the monitored resource requests; establishing a plurality of connections from the intermediate server to a subset of the plurality of remote servers, said subset being determined on the basis of the generated statistics data; and storing data indicative of the plurality of established connections in a connection cache. Caching of connections in this manner ensures efficient use of proxy server resources by only caching connections to “popular” remote servers.
Abstract:
There is described a system for adding content to a data container, the data container comprising one or more segments arranged in a sequence, each segment containing payload data and wherein at least one of the one or more segments is compressed. The system comprises parsing through at least a portion of the data container so as to determine at least one of a beginning and an end of the sequence of segments; and adding content to the data container at the at least one of the beginning and the end of the sequence of segments, while the at least one of the segments remains compressed.
Abstract:
A method, apparatus and non-transitory computer medium are provided for encoding data of a media file for playback by a user equipment in a communications network. A request for a range of encoded data is received from the user equipment, the encoded data to be generated by encoding data from an original media file. The request for a range of encoded data is converted into a request for a range of original data from the original media file. The range of original data is retrieved and the range of original data is encoded to generate encoded data. The requested range of encoded data, from the generated encoded data, is provided to the user equipment.
Abstract:
A method, apparatus and computer program are provided for controlling access to content in a network 400 comprising a user equipment (UE) 402 and servers 406, 434. The UE 402 comprises an application module configured to process executable code using data retrieved from a first server 406. A request message 436 comprising first data identifying the first server 406 associated with the application module and second data indicative of a request for content from a second server 434 received from the application module 428 is analysed so as to determine an access permission. The access permission is based on an attribute of the second server 434 satisfying a predetermined criterion with respect to the first server 406. An access control parameter is selectively included in a response message 442, 448 in dependence on the access permission to provide permission to access retrieved content included in the response message 442.

Abstract:
Provided herein is a method of managing connections in a communication network. A first and second packet are received from a third entity intermediate to a first and second entity in the communication network. The first packet and the second packet are used to establish a third transport protocol socket and a fourth transport protocol socket at a fourth entity. Header field re-valuing information is established based at least in part on first header field value information obtained from the first packet and/or second header field value information obtained from the second packet. Header field values in a subsequent received packet are re-valued based on the header field re-valuing information, either prior to the subsequent packet being input to the third transport protocol socket or the fourth transport protocol socket or subsequent to the subsequent packet being output from the third transport protocol socket or the fourth transport protocol socket.
Abstract:
A method for categorizing a downloading of a resource to a user device from a resource server in a data network is provided. Data of one or more Layer 7 protocol requests from the client device is received at an intermediate server in the data network. The intermediate server forwards the data of each of the one or more Layer 7 protocol requests to the resource server and receives data of one or more Layer 7 protocol responses from the resource server, each Layer 7 protocol response corresponding to a respective one of the Layer 7 protocol requests. The intermediate server categorizes the downloading of the resource to the client device as being one of one or more pre-defined download categories, based on a count of the one or more Layer 7 protocol responses and the determined sizes or estimated sizes of the one or more Layer 7 protocol responses.
