    摘要: Methods and apparatus are provided for recovering from packet loss in an end-to-end network connection having at least one wireless segment. A packet on a wireless segment of an end-to-end network connection is processed by determining whether the packet comprises one or more of a lost packet and a malformed packet; and generating a modified packet for an application associated with the packet to replace one or more of the lost packet and the malformed packet if the application is substantially tolerant to one or more of lost and malformed data. The modified packet comprises, for example, a non-original packet and/or a corrected packet. Link layer information or information from a deep packet inspection can be used to determine whether the packet comprises a lost packet or a malformed packet.

    摘要: One or more embodiments perform byte caching. At least one data packet is received from at least one network node. At least one data object is received from the at least one data packet. An object type associated with the at least one data object is identified. The at least one data object is divided into a plurality of byte sequences based on the object type that is associated with the at least one data object. At least one byte sequence in the plurality of byte sequences is stored into a byte cache.

    摘要: A method, system and computer program product for creating a customized message in a video-on-demand service, in which a user accesses the service using a communications device. In an embodiment, the method comprises using a video-on-demand server to intercept the access by the user of the video-on-demand service, obtain information about video content of a local cache of the video-on-demand service, obtain a profile of the user, and identify a context of the user. A customized message is constructed for the communications device based on the information about the local cache, the profile of the user, and the context of the user. The video-on-demand server sends the customized message to the communications device. In one embodiment, the user accesses the video-on-demand service through an edge base station of a core network, and the video-on-demand server is in this base station of the core network.
