Network programming framework system and method based on asynchronous IO model

Abstract

The invention provides a network programming framework system and method based on an asynchronous IO model, and the system comprises a channel layer which is used for receiving to-be-processed original data; a pipeline layer which is used for reading the original data from the channel layer and operating the original data through a plurality of stored processor nodes; wherein the plurality of processor nodes are connected end to end through forward pointers and backward pointers to form a chain type processing model in a responsibility chain form, and each processor node is bound with a workerthread, so that the method of the processor node is executed in the bound worker thread. According to the embodiment of the invention, a single-thread running environment is provided for the processor node through the design of the context of the processor on the pipeline layer and the processor node, so that the coding difficulty can be reduced by giving the single-thread running environment toeach processor node, and the running performance can be improved by giving the possibility of serialization running of an overall responsibility chain mode.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a network programming framework system and method based on an asynchronous IO model. Background technique [0002] In terms of network programming, the operating system provides several network models for upper-layer applications, namely: blocking IO model, non-blocking IO model, IO multiplexing model, signal-driven model, and asynchronous IO model. In terms of API at the language level, the Java language provided a Socket socket interface in JDK1.0, providing support for the blocking IO model. Support for the non-blocking IO model was provided in the JDK1.4 version. Support for the asynchronous IO model was provided in the JDK1.7 version. [0003] The blocking IO model is relatively simple to implement and apply, but when the amount of concurrency is high, the overall performance of the program is not high enough, and the overhead is relatively high. Because of the blocking...
