  • Patent number: 11063878
    Abstract: A network and a communication method are described. The network comprises: source nodes, receiver nodes, and coding nodes. The coding nodes are connected with input links for communication of input signals to the coding nodes and output links for communication of output signals from the coding nodes. The output signals are a linear combination of the input signals. The coefficients of the linear combination are deterministically chosen based on local information available locally at the coding node.

  • Patent number: 10965538
    Abstract: 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.

  • Publication number: 20170134165
    Abstract: A network and related methods for transmitting processes in a network secretly and securely is described. The network use keys, through path-key establishment and a key pool bootstrapping, to ensure that packets are transmitted and received properly and secretly in the presence of one or more adversarial nodes.

  • Patent number: 9632829
    Abstract: Allocation of storage budget in a computer-based distributed storage system is described, where associated computer-based storage nodes have heterogeneous access probabilities. The problem is to allocate a given storage budget across the available computer-based nodes so as to store a unit-size data object (e.g. file) with a higher reliability (e.g. increased probability for the storage budget to be recovered). Efficient algorithms for optimizing over one or more classes of allocations are presented. A basic one-level symmetric allocation is presented, where the storage budget is spread evenly over an appropriately chosen subset of nodes. Furthermore, a two-level symmetric allocation is presented, where the budget is divided into two parts, each spread evenly over a different subset of computer-based storage nodes, such that the amount allocated to each node in the first subset is twice that of the second subset.
