Design method for improving memory usage rate of buffer area in network programming

Abstract

The invention provides a design method for improving a memory usage rate of a buffer area in network programming, and relates to the field of network communication. A network layer processing message packet initializes a chain table of a buffer, and the chain table of the buffer area is only provided with one node of the buffer area and a distributed space for the node of the buffer area is 8KB. According to a service layer providing the source of the message packet, when the message packet is transmitted to the network layer to be processed, if the content of a message is smaller than 8KB, the message is placed on a first node of the buffer area of the chain table of the buffer area. A reading side taking out the data of the buffer area takes the data from the chain table of the buffer area of the network layer, and whenever reading of a buffer area is finished, the node of the buffer area is released from the chain table of the buffer area until the last buffer area. The design method for improving the memory usage rate of the buffer area in the network programming solves the problem that a usage rate is low due to the fact that an integrated continuous buffer area cannot retrieve part of internal memory.

Description

Technical field: [0001] The invention relates to the field of network communication, in particular to a design method for improving the utilization rate of buffer memory in network programming. Background technique: [0002] At present, many network communication libraries use a buffer that can automatically expand in the design of message buffers. The basic strategy is as follows: [0003] 1. When the buffer is not enough to store new messages, it will organize the memory internally to see if it can free up enough space. [0004] 2. If there is not enough space to store, then expand the buffer to double the original size, and the expanded buffer will not shrink. [0005] There will be no problem in doing ordinary stable transmission, but if the business layer puts a large piece of message packet (more than 2MB) into the buffer, or the business layer quickly puts small pieces of data into the buffer , and the underlying IO multiplexed thread does not have time to respond d...

Problems solved by technology

[0006] The purpose of the present invention is to provide a design method for improving buffer memory usage in network programming, which can connect buffer nodes one by one to form a buffer linked list, thus satisfying data of any size Stored in; and the structure of the linked list is very strong in addition and deletion, and each node is independent and can be recycled individually, which solves the problem that the entire continuous buffer cannot reclaim part of the memory, resulting in low usage
