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.

Split data path distributed network protocol

A high speed data communications method and system is provided whereby multiple groups of software interfaces are used to link a Distributed Systems Services Unit to a Network Provider which connects to an Input/Output Interface Module which relates to external interfaces of a Network. The interfaces permit the capability of buffer sharing and lock pool sharing, in addition to improved Connection Library Element Interfaces which reduce the overhead that was previously required and further enables faster data transfer operations with reduced latency.

Multiple interface data communication system and method utilizing

An improved high-speed data communications system is provided having software functions which permit a Network Data Path Interface to work in conjunction with a Distributed System Service application and a Network Provider application for enhancing data transfers to a Input/Output module and Network Processor. The improved Network Data Path Interface functions involve transmitting data outward to Channel Adapters via the use of shared buffers which can be re-used after utilization, and also receiving data by the sharing of buffers between a Distributed System Service application software unit, a Network Provider unit, and the Network Data Path Interface, enabling data to be received by the Network Provider for transferral to the Distributed System Service application unit.
