Abstract: A method of performing a compression operation on data in a mobile communication network. An intermediate node located between a mobile terminal and a mobility anchor point node, receives a data payload. If the intermediate node has access to compression information required to perform the compression operation, it performs the compression operation to generate a modified data payload and sends the modified data payload to a next node. If the intermediate node does not have access to compression information required to perform the compression operation, it sends the data payload to the next node. The compression operation may be data compression or de-compression.

Abstract: An approach for multi-stream data compression comprises receiving packets of a data stream, wherein the packets comprise respective packets of source data streams compressed on an aggregate basis and in a successive order. A one of the packets is decompressed, and a determination is made whether the packet has been received in a proper order of succession compared to the successive order of compression. When it is determined that the packet has been received in the proper order, the packet is stored at a next location in a decompressor cache. When it is determined that the packet has not been received in the proper order, the packet is stored at a location in the decompressor cache, allowing for subsequent storage of one or more further packets in the proper order of succession, wherein the further packets were processed via the compression process before, but were received after, the one packet.

The packet routing component can then update, or otherwise modify, packet routing information used by one or more of the POPs. Accordingly, the packet routing management component can then selectively distribute the updated or modified packet routing information, including the distribution to all POPs, the targeted distribution to specific POPs and the creation of centrally accessible routing information.

Abstract: In a method for coding a packet of information words into a frame for transmission, blocks of input data are received, the input data including control words and the packet of information words, the packet having (a) a start preceded by ones of the control words and (b) an ending followed by others of the control words, the blocks being smaller than the packet.

When the block does not consist exclusively of information words: the block is condensed to accommodate a TYPE word, the TYPE word is inserted into the block, and a one bit block header having a second sense, opposite to the first sense, is appended to the block to form the frame.

Abstract: Methods and apparatus teach a digital spectrum of a file. The digital spectrum is used to map a file's position in a multi-dimensional space. This position relative to another file's position reveals distances between the files. Closest files can be grouped together. When contemplating voluminous numbers of files for digital spectrums, various methods include: concatenating all such files together to get a single key useful for creating a file's spectrum; or compressing files individually and combining their collective dictionaries into a single dictionary with or without the use of tree mechanisms that defines the digital spectrum. Each provides advantage over the other. The latter consumes considerably less run time because each compression event can be distributed to a separate processor. Method two provides better spectrums because it is more “informationally” valid than is method one.

Abstract: System and method embodiments are provided for adaptive bandwidth management for transporting rendered graphics in a virtual desktop infrastructure. The embodiments include a video detection algorithm that enables a driver for a graphics processor at the server's end to identify displayed video data at the user'send. The driver identifies video traffic that is sent to the user device by tracking repeated bitmap operations at the same display area or block of an application displayed window at the user device. When the number of bitmap operations reaches a pre-determined threshold, then the corresponding area is considered a video display area. When detecting that a bandwidth threshold for transporting graphics data from the server to the device is reached, the data corresponding to the detected video area is compressed using a higher compression rate, thus increasing the loss rate of transferred video data to improve playback experience for the user.

Abstract: Systems and methods are described for avoiding redundant data transfers using delta coding techniques when reliably and opportunistically communicating data to multiple user systems. According to embodiments, user systems track received block sequences for locally stored content blocks. An intermediate server intercepts content requests between user systems and target hosts, and deterministically chucks and fingerprints content data received in response to those requests. A fingerprint of a received content block is communicated to the requesting user system, and the user system determines based on the fingerprint whether the corresponding content block matches a content block that is already locally stored. If so, the user system returns a set of fingerprints representing a sequence of next content blocks that were previously stored after the matching content block.

Abstract: A method and apparatus of providing high performance and highly scalable storage acceleration includes a cluster node-spanning RAM disk (CRD) interposed in the data path between a storage server and a computer server. The CRD addresses performance problems with applications that need to access large amounts of data and are negatively impacted by the latency of classic disk-based storage systems. It solves this problem by placing the data the application needs into a large (with respect to the server's main memory) RAM-based cache where it can be accessed with extremely low latency, hence improving the performance of the application significantly. The CRD is implemented using a novel architecture which has very significant cost and performance advantages over existing or alternative solutions.

Abstract: A communication channel in a network maintains client-server transparency while providing reduced bandwidth in the channel. A first and second node can communicate a compressed form of the object data between themselves in the channel. One of the first or second nodes hosts a cache database that can store, transparently to the client, the requested object data.

One of the nodes can provide control signals to the other node to indicate whether the requested object data is stored in the cache database. This configuration preserves transparency between the client and the server while permitting reduced bandwidth usage between the first and second nodes via the compressed object data.

Abstract: Detection of errors in a video stream occurs by calculating an error detection code, such as a Cyclic Redundancy Check (CRC) code over a group of not more than N macroblocks in a slice of the stream prior and after transmission, where N is an integer greater than zero but less than the total number of macroblocks in the slice. A comparison of the error detection codes reveals whether any errors exist in the group of macroblocks. If the group has no errors, normal decoding occurs. If the macroblock group has an error, then the macroblock group, and the remaining blocks in the slice undergo error concealment.
