摘要
针对移动代理的容错协议没有统一评价标准的现状,比较了移动代理的容错协议在实际系统中的应用,并根据协议所采用的容错机制对各种现有容错协议进行了分类,提出暂时复制、空间复制、管道线、中心控制点分类方法,提出了使用随机Petri网(SPN)作为容错性能评价标准,描述了暂时复制容错协议。
Aiming at the problem of there no unify evaluate criterion of performance of the mobile agent fault tolerance protocol,the practical applications of several FT protocols are compared,a new class method is put forwarded based on the mechanism of the FT and the protocols are classified according it,it's the TRB\SRB\Pipeline\Center manager.The SPN method is bring forward as the evaluate criterion of FT protocol performance and the TRB is described as an example.
