Abstract

A network node that implements a distributed TCP/IP network communication protocol stack, with the protocol stack including a TCP layer and an IP layer. The TCP layer includes a TCP management unit and a TCP data path unit, and the IP layer includes an IP management unit and an IP data path unit. The network node comprises a network host configured with the TCP management unit and the IP management unit, and at least one I/O adapter coupled to the network host and configured with the TCP data path unit and the IP data path unit. In this manner, the TCP data path unit and the IP data path unit are distributed onto the I/O adapter.
