A Dedicated Serialization Scheme in Homogeneous Cluster RPC Communication

RPC is a communication technology which has been widely used in distributed systems. It has been employed as an essential component of distributed systems. However, the performance of traditional RPC technology will be seriously decreased in high-speed network based cluster system. The main reason is that the network of cluster has many obvious features such as high bandwidth, low latency, and high reliability, etc, which are different from normal network environment. Therefore, how to improve the performance of RPC technology in cluster system has caught increasing attention.

In this paper, we have carefully studied the traditional RPC technology, which suggest that the decreasing of cluster network performance is mainly caused by the

serialization/deserialization

process of RPC technology. Thus we proposed a dedicated

serialization/deserialization

scheme which can run on homogeneous cluster system. This scheme can well improve the performance of cluster network by reducing the number of date copy operations of RPC protocol. We have evaluated our improved scheme in our real-world cluster system. And our evaluation results show that our scheme can significantly promote performance of bandwidth by up to 43% in our cluster system when the size of transmitted data block is large.
