ABSTRACT:
A method, system, and computer program product for delivering data, received from a network on a network adapter to a pre-assigned port, to a storage buffer assigned to an application are disclosed. An application designates an application-specific buffer within a local data processing system for buffering data communicated with the application. The local data processing system reports to a network interface of the local data processing system a memory address of the designated application-specific buffer, and the data processing system designates a port on which to receive packets addressed to the memory address. The data processing system then sends a port registration message to the local network interface, enabling the network interface to compare the port number of incoming traffic to a registered port number and route incoming traffic from a remote data processing system directly to the designated application-specific buffers in the event of a match. In one embodiment, the present invention includes receiving in the network interface a packet addressed to the specific port and delivering data from the packet to said application-specific buffer.
