Abstract: Systems and methods of storing previously transmitted data and using it to reduce bandwidth usage and accelerate future communications are described. By using algorithms to identify long compression history matches, a network device may improve compression efficiently and speed. A network device may also use application specific parsing to improve the length and number of compression history matches. Further, by sharing compression histories, compression history indexes and caches across multiple devices, devices can utilize data previously transmitted to other devices to compress network traffic. Any combination of the systems and methods may be used to efficiently find long matches to stored data, synchronize the storage of previously sent data, and share previously sent data among one or more other devices.

Abstract: A method an apparatus is provided to generate a gray code sequence from a sequence of binary values having a length “L”. Accordingly, one aspect of the present invention provides a circuit comprising a cycle flag toggle circuit configured to toggle a cycle flag between a first value and a second value, an intermediate value generator coupled to an output of the cycle flag toggle circuit configured to receive the binary value, and configured to generate an intermediate value from the cycle flag and the binary value, and a binary to gray converter coupled to an output of the intermediate value generator, configured to convert the intermediate value to a gray code.

Abstract: A method and system allows for fast compression and decompressing of data using existing repetitive interleaved patterns within scientific data (floating point, integer, and image). An advantage of the method and system is that it is so fast that it can be used to save time due to a lower amount of data transferred/stored in scenarios like network transfer, disk or memory storage, cache storage or any other real-time applications where time plays a crucial role.
