Embodiment 300

[0046] In order to more clearly illustrate the solution of the present application for detecting network topology, the method embodiment 300 is used for a detailed description below. Such as image 3 As shown, the method embodiment 300 includes:

[0047] Step S1: The detection server 202 learns the downlink address of the network device 201 through the Border Gateway Protocol (BGP).

[0048] In order to subsequently check the connectivity of the downlink addresses of the network devices 201 , the detection server 202 needs to obtain the downlink addresses of each network device 201 in advance. The detection server 202 in the embodiment of the present application obtains the downlink interconnection address of each network device 201 through BGP learning. The BGP protocol is an autonomous system (AS) routing protocol running on TCP, and its main function is to exchange network routing information. Of course, other methods may also be adopted in practical applications to enab...

Abstract

The invention discloses a network topology detection method and system and a storage medium. The method specifically comprises the steps that a detection server learns a downlink interconnection address of network equipment through a border gateway protocol (BGP), constructs a transmission control protocol (TCP) message for the downlink interconnection address of the network equipment, and carriesout the connectivity check; an in-band network telemetry technology (INT) message is constructed and forwarded according to the TCP message; when the network equipment receives the INT message, if the network equipment judges that the network equipment is the destination address of the INT message, metadata information is added to an INT message reporting and collecting server; the acquisition server determines the network topology according to the Metadata information so as to achieve the purpose of detecting the network topology. If any fault occurs in the network equipment, accurate faultanalysis can be performed according to the network topology, and therefore the maintenance and management of the network are enhanced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, system and storage medium for detecting network topology. Background technique [0002] In-band Network Telemetry (INT, In-band Network Telemetry) is a technology that can monitor network traffic. INT technology is configured on the network detection server, and the collection server collects Metadata data on the network devices on the packet forwarding path, and accurately monitors the network status through the analysis of Metadata data. The Metadata data described here generally includes information such as device information, inbound and outbound interface information, queue information, and time stamps. [0003] figure 1 It is a schematic diagram of an application scenario of the prior art. Such as figure 1 As shown, it is assumed that service server A, service server B, network device 1, network device 2, network device 3, and network devi...
