IPMI communication system and dependable communication method

Abstract

The invention relates to an IPMI communication system and a reliable communication method, wherein the system comprises a physical layer (81), an intermediate layer (82) and an application layer (83), wherein the intermediate layer (82) works like this: adopting an IPMI message format and a request or response pattern and re-sending request message under the condition that an error response is obtained or a response is unavailable overtime, and the method adopts retransmission sending and blocking type receiving. The system and the method reliably realize a payload interface and finish the communication between the HOST side and the IPMC on an ATCA veneer accurately and high-effectively, and the operation conditions of various services on the veneer can be obtained through an IPMI communication channel which is realized, the IPMC can know the whole veneer more completely, which enables the control to the veneer to be more accurate and effective, simultaneously, the HOST side of the veneer also can obtain more information from the IPMC, which enables the system to operate more reliably on the whole veneer.

Description

technical field [0001] The invention relates to the field of advanced telecommunication computing architecture, and mainly relates to a communication subsystem between a HOST and an IPMC on a physical single board and a method for realizing reliable communication on a payload interface of the system. . Background technique [0002] With the continuous development of telecommunication technology, telecommunication network products are also becoming more and more mature, playing an increasingly important role in social production and life. Moreover, various applications have put forward higher requirements on the performance and operation and maintenance functions of telecommunication products. [0003] In order to better realize the maintenance and management of telecommunication products, each telecommunication manufacturer has its own maintenance and management system. Through these management systems, the daily management and maintenance of telecommunications products ar...
