A Processing Method of Grain Depot Monitoring Network System Based on Cooperation Between ASs

Abstract

The invention discloses a grain depot monitoring network system processing method based on inter-AS cooperation. A plurality of dependency processing nodes are set in each AS, and the processing nodes in the AS elect a master node and a slave node through an election algorithm according to priorities, and the master node Responsible for receiving and assigning dependency tasks, slave nodes are responsible for processing specific dependency processing tasks, constructing local dependency information based on program access paths and explicit dependencies; multiple AS processing nodes between ASs through task decomposition and collaboration After obtaining the partial dependency information, the source processing node synthesizes the partial dependencies of multiple ASs to generate overall dependency information and returns it to the user. The invention provides users with deterministic dependency relationships among grain depot monitoring networks, expands the processing range of the dependency relationships, and improves the integrity of the dependency relationship processing results.

Description

[0001] technical field [0002] The invention relates to a network relationship processing method, in particular to a grain depot monitoring network system processing method based on inter-AS cooperation. Background technique [0003] In order to build and maintain the grain depot monitoring network system, it can be mainly divided into three aspects: the first is to discover the mutual relationship between the networks through active measurement, including X-trace discovering by adding identification data in the data packet Dependencies between network programs; the second is to discover the interrelationships between networks by passive measurement. Orion discovers the dependencies between them by analyzing the delay distribution between target programs, and Constellation analyzes the time of incoming and outgoing data packets. The relationship between stamps is used to discover the dependencies between data streams; the third is to discover implicit dependencies by ana...

Problems solved by technology

[0004] The traditional way of building and maintaining the grain depot monitoring network system has the following problems: (1) The traditional processing method measures the performance parameters in the network through the network measurement method, and then infers the relationship between network programs through these performance parameters. The accuracy of the relationship obtained by this method is not high, and it needs to consume a lot of network measurement resources; (2) The traditional processing method has a small coverage and is often limited to a specific AS. Because the relationship between network programs often involves network The range is relatively large, the coverage of the traditional method is not enough, and the processing results obtained are not complete; (3) With the expansion of the network scale, the processing difficulty of the traditional processing method will become very high, and it does not have good scalability
