远程过程调用RPC机制是分布系统和计算机网络中进程间通信的新型机制,在分布应用设计中得到了广泛应用。但是,现有的RPC系统在并行性、可靠性和透明性等方面都有或多或少的缺陷。为此,我们将进程级概念引入到RPC系统中,提出了支持分布系统分布实体间相互协作的新型通信合作机制——成组远程过程调用GRPC制。实践证明,GRPC机制不仅可以改善RPC系统的并行性、可靠性和透明性,而且可以使得RPC系统支持组通信。
Remote procedure call RPC mechanism is a new mechanism of communication between processes in distributed system and computer network. It has been widely used in distributed application design. However, existing RPC systems have more or less defects in terms of parallelism, reliability and transparency. To this end, we introduce the process-level concept into the RPC system and propose a new type of communication cooperation mechanism-Group Remote Procedure-Invocation (GRPC) -which supports distributed system distributed entities to cooperate with each other. Practice has proved that, GRPC mechanism can not only improve the parallelism, reliability and transparency of RPC system, but also make RPC system support group communication.
