  • Patent number: 11172054
    Abstract: This disclosure relates to offloading processing intensive tasks in communication protocol specific operations off the device, e.g. to another network node connected to the device via a network. Such tasks may for example include flow control, segmentation/desegmentation, and/or error control. As part of error control, protocols of the transport protocol layer of the OSI protocol stack may include checksum calculation to ensure reliability of the (payload) data. The calculation of checksums may be processing intensive. For this reason, example client nodes that realize the offloading of processing intensive tasks in communication protocol specific operations to another network node may not utilize any transport layer protocol at all, but rely on flow control and error control implemented in most modern data link layer protocols (Layer 2 of the OSI protocol stack). Accordingly, the processing intensive tasks can be “shifted” from the client device to another device.

  • Patent number: 10560572
    Abstract: A telecommunications addressing system/method allowing selection of a telephone instrument device (TID) using arbitrary identifiers is disclosed. The system/method allows a source TID (STD) to select a target TID (TTD) by the use of a Target Telephone Identifier (TTI) data string rather than a traditional numeric telephone identification (NTI). This TTI is then indexed within a TTI/NTI mapping server (TMS) that functions as a hierarchical repository of TTI/NTI mappings. STD/TTD communication is established by first performing a lookup of the STD-selected TTI within the TMS to identify the NTI of the TTD. Once the NTI of the STD has been identified by the TMS, communication between the STD and TTD is established using the NTI via the normal public switched telephone network (PSTN). TMS TTI lookup may be performed via STD TID web application and/or via PSTN infrastructure interface.

  • Patent number: 10348612
    Abstract: Embodiments relate to setting up direct mapped routers located across independently managed compute and storage networks for enabling multiple modes of communication over the cross-coupled links between the networks. An aspect includes identifying a characteristic of a local entity based on a unique location identifier assigned to the local entity and learning a characteristic of a remote entity based on a location identifier received over a cross-coupled link between the local entity and the remote entity. A port on a local entity router is then correlated with the received location identifier of the remote entity. A route is then built in the direct mapped router table at a location pointed to by the location identifier of the remote entity. An optimistic failover route is established from a storage entity to a compute entity when a cross-coupled link between the storage entity and the compute entity is broken.
