用户层通讯工业标准VIA的设计思想与工作机制

摘要：

SAN(System Area Network)within cluster brings high bandwidths and low latencies to IPC(Inter-Process Communication). However,the communication performance has not been able to makefull use of these hardware improvements due to many software overheads. To address this problem,In-tel Corporation,Compaq Computer Corporation, and Microsoft Corporation jointly authored the VIA (Virtual Interface Architecture)specification.As an industrial standard of ULN(User-Level Networking),Ⅵ Architecture defines a set of data operations for message passing, to achieve high-bandwidth, low-latency communication between any couple nodes within cluster ,as well as minimize CPU cycles. VIA gives direct access to network inter-face,bypasses operating system in memory region protected mode ,avoid copies of data during message passing ,and avoid interrupts and context switches if possible.This article describes the principles and mechanism of the Ⅵ Architecture and THVIA.
