System and method for implementing RapidIO network universal socket

Abstract

The invention provides a system and method for implementing a RapidIO network universal socket. The system comprises a universal interface layer, a command line and a BSD interface layer, wherein an application layer uses a socket interface for carrying out RapidIO network communication; a user views and configures equipment, a topological relationship and protocol stack parameters of a RapidIO network; and a new RapidIO network protocol stack is created by utilizing a kernel function provided by the BSD interface layer. According to the system and the method which are provided by the invention, a set of TCP / UDP-like programming interfaces is provided for a user, an application protocol based on data streaming and a datagram is implemented, direct I / O communication and message transmission are used as network drivers, and high-speed communication is implemented.

Description

technical field [0001] The present invention relates to a system and method for realizing a general socket, in particular to a system and method for realizing a RapidIO network general socket. Background technique [0002] RapidIO is an open standard for system interconnection and switching fabric, which meets the extensive application requirements of embedded infrastructure. Feasible applications include connecting multiple processors, serial backplane interconnects, DSP array groups, storage subsystems, wireless base stations, fault-tolerant systems and other fields. This technology will mainly be used as the internal interconnection of the system, supporting chip-to-chip and board-to-board communication, and can achieve performance levels from 1Gbps to 10Gbps. [0003] However, it must be seen that even with the support of high-speed hardware interconnection protocols, it is still very difficult to provide end users with high-speed communication interfaces. Redundant me...

[0003] However, it must be seen that even with the support of high-speed hardware interconnection protocols, it is still very difficult to provide end users with high-speed communication interfaces

Redundant memory copy and heavy communication overhead are increasingly becoming the bottleneck affecting the communication performance between multiprocessors. For example, the RapidIO communication interface implemented by the Ethernet emulator under the Linux kernel only plays 10% of the RapidIO communication performance. Left and right, mainly because the overhead of the upper layer TCP / IP software protocol is too large

In addition, at present, there is no unified standard for the bare driver interfaces independently developed by various manufacturers, and they are often inconsistent. It is inconvenient for existing Ethernet-based application software to use RapidIO network communication, and users are also worried about the binding of product software and hardware manufacturers.
