Problems solved by technology

Although these tasks are initiated by different users, they may be the same task, which will cause repeated measurements
In addition, for different measurement tasks, the process of collecting data may be partly the same, which will also cause repeated measurement.
Therefore, in a large network, there are a large number of different measurement requirements from different users (such as network administrators, application developers, end users) and different analysis applications (such as attack detection, attack and defense effectiveness evaluation, network performance analysis, etc.) , performing data acquisition independently for each measurement requirement will cause the measurement cost to increase linearly with the number of measurement tasks, affecting the scalability of the measurement system

Embodiment Construction

[0041] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] In the prior art, the Top-Down network measurement system architecture is as follows

[0043] figure 1 As shown, the working process is: different measurement intentions from users or applications are expressed as three measurement tasks: measurement task 1, measurement task 2, and measurement task 3, and the three measurement tasks are expressed as three queries through the declarative interface: Query 1, Query 2, and Query 3, compile the three queries into executable rules through the compilation module, and then deploy them to network devices such as switches and routers for data collection. Among them, the declarative interface is the query interface provided by the Top-Down network measur...

Abstract

The invention provides a method and a system for optimizing a parallel measurement task for a TopDown network measurement system, provides an optimization technology of a reuse query result aiming atthe expansibility problem of the TopDown network measurement system during execution of the parallel measurement task, and provides a method and a system for optimizing the parallel measurement task for the TopDown network measurement system; by expanding a declaration type interface and a compiling module of the TopDown network measurement system, the expenditure of the system when executing theparallel measurement task is reduced, and the expansibility of the system is ensured.

Description

technical field [0001] The invention belongs to the technical field of computer network measurement, and in particular relates to an optimization method and system for a parallel measurement task oriented to a Top-Down network measurement system. Background technique [0002] Many network management tasks such as traffic engineering and network security need to analyze the statistical information of network traffic, so they rely on network measurement to provide real-time and accurate collection of network traffic statistics. [0003] Existing network measurement systems can be divided into two categories: [0004] One is the bottom-up network measurement system. This type of network measurement system configures measurement rules to collect data according to the measurement functions (such as port mirroring) supported by each network device. The measurement and analysis tasks of the upper layer can only be performed according to the measurement rules. The provided data is ...
