Problems solved by technology

But it only encapsulates a layer of graph logic on the NoSQL database, and cannot represent the real-time change information of the network
On the other hand, it is based on disk storage, and its access speed is limited by I / O bottlenecks, which cannot meet the rapid changes of real-time networks.

Embodiment Construction

[0073] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0074] In order to verify the effectiveness of the dynamic network graph database, a network simulation experiment environment based on Docker container technology is constructed in the experiment, and multiple switches are virtualized on a single physical host. The designed network topology is as Figure 4 shown. In the figure, the four dark-colored nodes are EGP core switches, and the light-colored nodes are IGP switches. The EGP switches are border switches in their respective autonomous domains, and each EGP switch is connected to the IGP switches in the form of a binary tree. There are three layers of IGP switches in each autonomous domain, and the last layer of IGP is connected to end devices such as common hosts.

[0075] The types and quantities of each node in this network topology are as follows:

[0076] node type Number of nodes (u...

Abstract

The invention discloses a construction method of a dynamic network atlas database reflecting network multi-dimensional resources. The method comprises the following steps: acquiring and storing real-time information of each node and link in a network view, wherein the real-time information comprises mode CPU utilization rate, node memory utilization rate, node name, node IP and link delay, link bandwidth and link packet loss rate; constructing a distributed graph database by using a memory database; adding a multistage storage mechanism and incremental index design; carrying out data aging; and storing historical data into a disk. Nodes in network topology are divided into three levels, namely a centralized management center, distributed agent measurement points and common end nodes, the centralized management center issues measurement instructions to the agent measurement points, the agent measurement points report measurement data to the management center, and updating of a dynamic network atlas database is achieved.

Description

technical field [0001] The invention belongs to the technical field of network measurement, and in particular relates to a construction method of a dynamic network map database reflecting network multi-dimensional resources. Background technique [0002] Network management tends to become more complex with computer networks. A computer network is a collection of devices and lines that provide a means of transmitting data between computers, enabling users at different locations to share resources. Network management requires the management device to have an overall and effective perception of network parameters from macroscopic flow control to detailed packet processing. In the process of measuring various multi-dimensional resources of the network, how to store various parameters of the network becomes the key to enable the network to be used and operated normally, safely, efficiently and reasonably. In order to ensure the robustness and reliability of the management metho...
