Problems solved by technology

All message transmission processes in the storage software built on the basis of RDMA-based network modules will go through the process of copying from NM to MR. Each memory copy will consume a considerable amount of CPU cycles. Canceling this memory copy process will improve the system to a certain extent. performance

Abstract

The invention discloses a method and system for optimizing network application performance based on remote direct data access, and the method comprises the steps: generating a memory space which comprises a preset number of memory segments; triggering a message creation request in response to the business process, receiving the message creation request through the weight-based priority queue, and enqueueing the message creation request into the weight-based priority queue; dequeueing the message creating requests from all the enqueued message creating requests of the weight-based priority queue, and allocating memory segments in the memory space for the dequeued message creating requests; generating a to-be-transmitted message based on the allocated memory segment; and transmitting the to-be-transmitted message based on the remote direct data access, and releasing the allocated memory segment after the transmission of the to-be-transmitted message is completed. Through the scheme of the invention, the opportunity and the response time of obtaining the memory by different types of messages are effectively controlled, the memory copy overhead and the demand of the system for the total memory amount are reduced, and the system performance and the message transmission efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of storage systems, in particular to a method and system for optimizing network application performance based on remote direct data access. Background technique [0002] The combination of TCP / IP protocol and Ethernet has become the current mainstream network solution. Hardware manufacturers and operating system developers work together to provide continuous performance improvement in order to meet the needs of various business scenarios and explosive data growth. In Linux, the kernel interacts with the hardware through interrupts; the TCP / IP protocol stack, as an indispensable part of the kernel, runs in the kernel space, is responsible for the analysis and control of data flow, and submits user data to the application layer. Before the TCP / IP protocol stack processes the message stream, any message stream from the hardware is first buffered into memory belonging to the kernel space. After any message flow...
