Embodiment Construction

[0032] The present invention provides a distributed computer system comprising end nodes, switches, routers and links interconnecting these components. End nodes can be Internet Protocol Set offload engines or Internet Protocol Set-based legacy host software. End nodes use send and receive queue pairs to receive and send messages. End nodes divide the message into frames and transmit the frames over the link. Switches and routers interconnect the end nodes and route the frames to the appropriate end nodes. End nodes reassemble these segments into messages at the destination.

[0033] Referring now to the drawings and in particular to FIG. 1, there is shown a diagram of a distributed computer system in accordance with a preferred embodiment of the present invention. The distributed computer system shown in FIG. 1 takes the form of an Internet Protocol network (IP network) such as IP network 100, and is provided for illustrative purposes only, and embodiments of the present i...

Abstract

A method, computer program product, and distributed data processing system for memory management. Memory regions are registered and have access rights and protection domains associated with them in response to receiving a request for a memory operation including a virtual address, which is used to address into a data structure. A second data structure is then used to translate the virtual address into physical addresses for the operation. A third data structure is used to allow an incoming request responsive to a remote operation being initiated.

Description

technical field [0001] The present invention generally relates to communication protocols between a host computer and input / output (I / O) devices. More specifically, the present invention provides a method for memory management in the context of communication between a host and an I / O device. Background technique [0002] In an Internet Protocol (IP) network, software provides a messaging mechanism that can be used to communicate with input / output devices, general-purpose computers (hosts), and special-purpose computers. Messaging mechanisms include transport protocols, high-level protocols, and application programming interfaces. The key standard transport protocols currently used on IP networks are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP provides reliable service while UDP provides unreliable service. In the future, the Stream Control Transmission Protocol (SCTP) will also be used to provide reliable services. Processes executing on a d...
