Abstract

This invention relates to a virtual interface structure user layer network communication system supported by hardware including network interface cards mounted on multiple computer hosts interacted with the host via PCI bus, cross switches connected with the network interface cards which are connected with the cross switches to form a communication network topological structure via physical links. The system also includes communication interface units composed of a user agent module and core agent module in each unit for realizing functions stipulated by VIA protocol and a drive module driving the cards to finish communication functions.

Description

technical field [0001] The invention belongs to the application technical field of user layer network and virtual interface structure protocol, and in particular relates to the realization technology of gigabit network communication system based on virtual interface structure. Background technique [0002] User Level Network (User Level Network-ULN) is proposed relative to the traditional key communication path must go through the core layer network (Kernel Level Network-KLN) of the operating system. With the rapid improvement of communication network hardware performance (communication bandwidth from 10M, 100M and even the current Gigabit, 10G network; the reliability of network communication has also been greatly improved), although the traditional core layer network can support long-message Application problems utilize the ever-increasing hardware network communication bandwidth to a certain extent, but for a large number of short message type application problems, the pe...
