Abstract: For logical multicasting in overlay networks, at a data processing system, an original unicast packet is received from a first component in a first computing node in an overlay network. To cause multicasting in the overlay network the received original unicast packet was unicast by the first computing node only to the data processing system, and a multicast data structure for the overlay network is maintained only by the data processing system, the multicast data structure containing information of each receiver that is configured to receive unicast packets during logical multicasting in the overlay network. From a set of subscriber receivers in the multicast data structure, a subset of the subscriber receivers is selected. A copy of the original unicast packet is unicast to each subscriber receiver in the subset.

Abstract: Disclosed is a novel system and method for maintaining computing functionality when a client device must be used in a low-power state. More particularly, when a client device is placed in a low-power state, sleep mode, or even shut-down, this method transfers aspects of the machine state onto a virtual machine in the cloud. This virtual machine may then function as a partial or full emulator of the user's client machine and thus can be: 1) accessed; and 2) communicated with by the machine's owner or others who use the machine. As long as the client device is shutdown, the cloud continues to temporarily function as the user's machine. Numerous embodiments are disclosed including a “hybrid decomposition feature” in which the data on the client machine is prioritized and then transfer to a server, typically a virtual emulator, component by component or piecemeal manner or manner.

Abstract: Embodiments include generating an error correction code by identifying two error-correcting codes of length n with minimum distances d and 2d, such that the second code is contained into the first code. Data is then encoded into t?1 blocks using the first code, and into the t-th block using the second block. The first t?1 encoded blocks are stored into t?1 blocks of memory locations, while the exclusive-OR (XOR) of such t?1 encoded blocks and the t-th encoded block is stored into a t-th block of memory location. The final encoded vector of length to is identified as belonging in a code with minimum distance 2d. Rotations of an encoded vector jn times are identified as belonging to the same equivalence class. A received vector or its rotations jn times can be successfully identified in the presence of up to d?1 errors, while d errors are identified as uncorrectable errors.
