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.
