Method and device of RPC (Remote Procedure Call) data transmission under homogeneous environment

Abstract

The invention discloses a method of RPC (Remote Procedure Call) data transmission under a homogeneous environment. The method comprises the following steps that: a plurality of small data blocks in data to be transmitted are copied to a sending cache by a sending end, and then the data in the sending cache are integrally sent to a receiving end, big data blocks in the data to be transmitted are directly sent to the receiving end, the big data blocks and the small data blocks are processed distinctively, and the big data are not copied, so that the copy expenditure is reduced, but the small data blocks are aggregated and sent, so that the sending expenditure is reduced; the receiving end receives the data from the sending end, and an address of each data block in a data receiving cache is computed and recorded, so that an upper program directly visits the data in the data receiving cache according to the address, and the data are no longer needed to be copied to the own cache from the data receiving cache, thus one-time copy expenditure is reduced. The invention further provides a system of implementing the method. According to the method and the system, the data copy operation of the sending end and the receiving end is effectively reduced, and the RPC transmission bandwidth between homogeneous machines is improved.

Description

technical field [0001] The invention relates to the technical field of cluster network communication, in particular to a remote procedure call (RPC) data transmission method and system in an isomorphic environment, which improves transmission performance when transmitting large blocks of data. Background technique [0002] RPC protocol (Remote Procedure Call Protocol) - remote procedure call protocol, which is a protocol that requests services from remote computer programs through the network without understanding the underlying network technology. The RPC protocol is widely used in distributed systems, and the performance of the RPC protocol is of great significance to improving the efficiency of data exchange in distributed systems. [0003] RPC provides a mechanism for transmitting data structures between different machines through the network, ensuring that calling programs on remote machines is transparent to upper-layer applications. When performing a remote procedure...

AI Technical Summary

Problems solved by technology

In some distributed systems, such as distributed file systems, a large amount of data migration operations are often required, which requires the system to be able to perform efficient data transmission, and the existing RPC protocol needs to encode and decode data during the calling process The operation involves the two data copy operations mentioned above, which has a great impact on the data transmission efficiency

[0005] For the above situation, the reason is that due to the consideration of data transmission between heterogeneous machines, it is inevitable to perform data copy operations in the process of encoding and decoding data.
