摘要： A network and a method for transmitting processes in a network are disclosed, where a randomized coding approach is provided. Network nodes transmit on each outgoing link a linear combination of incoming signals, specified by independently and randomly chosen code coefficients from a finite field. The approach allows robust, distributed transmission and compression of information in networks and is advantageous over routing-based approaches.

摘要： Systems and methods for characterizing networks are disclosed. In several embodiments, a network analyzer applies a network analysis to a network that replaces components of the network in a model of the network with equivalent or bounding models. The network analyzer can then characterize the simplified model of the network and an assessment can be made concerning the accuracy of the characterization of the network.

摘要： A method, apparatus and computer program product providing improved communication performance through network coding is presented. Coded packets are formed at a source node, the coded packets comprising a combination of original packets at the source node. The coded packets are transmitted to at least one destination node using an unreliable protocol. A reconstruction is formed based on received coded packets at the destination node, wherein when a number of received coded packets are equal to the number of transmitted coded packets the forming a reconstruction comprises forming a complete reconstruction and wherein when the number of received coded packets is less than the number of transmitted coded packets the reconstruction comprises forming a best attempt at reconstruction.

摘要： Embodiments of the invention present implementations for multiple access source coding (MASC). One embodiment presents an implementation directed at the lossless side-information case of MASC. Another embodiment gives an implementation of the general case MASC. One embodiment is a near-lossless implementation of MASC. In a two dimensional example, the invention provides a way to decode data pairs (x,y) from encoded individual data streams x and y. The present invention provides a solution that partitions the source code into optimal partitions and then finds a matched code that is optimal for the given partition. Embodiments of the present invention use Optimal Shannon, Huffman and Arithmetic Codes for the matched codes. Another embodiment of the present invention gives a method of finding near-lossless multiple access source coding.
