摘要:
Methods and apparatus are provided for performing byte caching using a chunk size based on the object type of the object being cached. Byte caching is performed by receiving at least one data packet from at least one network node; extracting at least one data object from the at least one data packet; identifying an object type associated with the at least one data packet; determining a chunk size associated with the object type; and storing at least a portion of the at least one data packet in a byte cache based on the determined chunk size. The chunk size of the object type can be determined, for example, by evaluating one or more additional criteria, such as network conditions and object size. The object type may be, for example, an image object type; an audio object type; a video object type; and a text object type.

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.

Various embodiments provide byte caching in wireless communication networks. In one embodiment, a plurality of data packets are received through an internet protocol (IP) data flow established between a wireless communication device and at least one server. Each of the plurality of data packets are combined into a packet bundle. A determination is made as to whether a second byte caching system is available. The packet bundle is transformed using one or more byte caching operations based on a second byte caching system being available. The transformed packet bundle is sent to the second byte caching system using an IP communication mechanism.

Various embodiments detecting wireless communication device mobility in a wireless communication network. In one embodiment, one or more Internet Protocol (IP) data packets associated with a wireless communication device are analyzed. The wireless communication device is coupled with the edge entity. A determination is made, based on the analyzing, that the wireless communication device is a newly coupled device at the edge entity. A central entity disposed within the wireless communication network is notified that the wireless communication device is currently coupled to the edge entity.

Systems and methods are provided for file searching on mobile devices. A system includes a user interface and a file query system. The user interface is for receiving a user-provided spatio-temporal query for use in searching for a particular file. The user-provided spatio-temporal query is provided by a user of a mobile device. The file query system is for determining information about the particular file responsive to the user-provided spatio-temporal query, and identifying from the information one or more files as a search result for the particular file.

The invention proposes a method for controlling a connection between a first network node and a second network node, wherein the connection is controlled by a packet filtering function filtering packets such that a packet is discarded in case a source address and/or a destination address do not comply with a filtering rule, wherein the packet filtering function is configured at a connection set up, and at least one of the first or second network node is adapted to change its address, the method comprising the steps of informing, the packet filtering function about the new address of the network node having changed its address, and updating the packet filter of the packet filtering function by using the new address of the network node having changed its address. The invention also proposes a corresponding network system comprising at least a network node and a packet filtering network element. Furthermore, the invention proposes a corresponding packet filtering network device.
