RPC data transmission method and system in a homogeneous environment

Abstract

The invention discloses an RPC data transmission method in an isomorphic environment. The sending end copies a plurality of small data blocks in the data to be sent to the sending buffer, and then sends the data in the sending buffer to the receiving end as a whole, and transfers the data to be sent to the receiving end. The large data blocks in the sent data are directly sent to the receiving end, which makes a distinction between large and small data blocks, large data is no longer copied, reducing copying overhead, and small data blocks are aggregated and sent, reducing sending overhead; the receiving end Receive data from the sender, and calculate and record the address of each data block in the data receiving cache, so that the upper layer program can directly access the data in the data receiving cache according to the address, and no longer need to copy data from the data receiving cache to its own cache , saving one copy overhead. The present invention also provides a system for realizing the above method. The invention effectively reduces the data copy operation of the sending end and the receiving end, and improves the RPC transmission bandwidth between homogeneous machines.

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.
