摘要： 现有的SNMP为保证对外提供一个更为开放、统一的接口,并没有限制变量绑定,协议栈大都按PDU中的变量顺序依次调用底层函数,这种调用往往是重复低效的。该文在不破坏协议的前提下,提出了一个基于MIB-interface的健康映射的设计方案,将Agent和底层间的接口透明化,并以接口函数列表为主处理流程,可以避免无谓的重复调用,实现了一个高效的SNMP Agent。

Abstract: In order to provide an open and uniform interface, current SNMP does not restrict the combination and sequence of variables. Many stacks resort to repeated calling interface functions according to variables’ sequence in PDU, which is obviously inefficient. Under the condition of not breaching protocol itself, a novel design of efficient SNMP agent based on MIB-interface healthy mapping is given. It makes the interfaces between agent and other modules transparent with equipment annotation, and employs the interface list as the main process, which can avoid unnecessary iteration of interface functions.
