Problems solved by technology

[0005] Due to the many types of services, there is currently no general method that can detect the service quality of each service function of the network equipment. Therefore, it is necessary for the operation and maintenance personnel to be familiar with the service function characteristics of the network equipment, and then manually deploy the detection points, so as to give the operation and maintenance personnel It brings a burden and increases the difficulty and complexity of operation and maintenance

Embodiment 1

[0166] The deployment of a tenant's VxLAN GW service is as follows: Figure 5As shown, the deployment information of the tenant's service flow is: the IP packet with the destination IP address IP A entering from the vNIC2 port is converted to VxLAN, and the VxLAN packet with the VxLAN ID a is output from the vNIC1 port.

[0167] Assuming that the tenant's VxLAN GW service is unreachable, preliminary detection finds that the fault occurs in Figure 5 shown in the server (English: server). The server includes multiple components, such as NIC, Open Virtual Switch (English: Open VSwitch, OVS for short), VxLAN GW VM, etc. Failure of any component in the server may cause the tenant's VxLAN GW service to fail.

[0168] In order to locate the faulty components in the server, a detection point deployment method is as follows Image 6 As shown, the specific implementation steps are as follows:

[0169] In the first step, the controller obtains the service template of the VxLAN GW ser...

Embodiment approach

[0209] Possible implementation methods are:

[0210] 1) According to the serial numbers in the captured detection messages, the controller matches the detection messages with the same serial number in the order of flowing through each sniffing point to form a message chain, which can be seen from the message chain The message status of a certain serial number message flowing through different sniffing points.

[0211]2) The controller compares the actual message features of different sniffing points in the message chain with the theoretical message features of the corresponding sniffing points in the expected template. If the actual packet characteristics of a sniffing point do not match the expected template, it means that there is a fault in the processing module between the sniffing point and the previous adjacent sniffing point. If the packet chain is broken after a sniffing point If the subsequent sniffing point does not capture the corresponding detection packet, it mea...

Embodiment 2

[0219] The method for detecting service quality of a network device provided by an embodiment of the present invention is described below in combination with a video stream transmission scenario.

[0220] Figure 8 Shown is a system architecture diagram for transmitting video streams, Figure 8 Among them, the video stream flows from a video server (English: video server) to a home set-top box (English: set top box, referred to as: STB).

[0221] In the video transmission service, there are often multiple paths in the video transmission path, such as Figure 8 The broadband remote access server (English: broadband remote access server, referred to as: BRAS) may transfer the video stream to router (English: router) A for transmission, and may also transfer the video stream to router B for transmission, and each path often There are various network devices, such as core router (English: core router, CR for short), firewall, gateway, router, optical line terminal (optical line ...

Abstract

The invention provides a detection method and device for the service quality of network equipment. By solidifying service function characteristics of the network equipment into a fixed part in a service template, operation and maintenance personnel do not need to know the service function characteristics of all the network equipment and only need to provide information such as flow identities and deployment information of to-be-detected service flows, a controller dynamically deploys detection points according to the service flow identities and deployment information which are provided by the operation and maintenance personnel and the fixed part in the service template to automatically detect the service quality of the network equipment, and therefore the operation and maintenance complexity and difficulty are reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for detecting service quality of network equipment. Background technique [0002] Operation, Administration and Maintenance (English: Operation Administration and Maintenance, OAM for short) has always been an important aspect in the field of telecommunications, and can be used to monitor network performance and detect network failures. At present, there are various OAM standards and protocols for traditional network equipment, such as the ITU-T Y.1731 protocol for the Ethernet layer of network equipment, and the Internet packet explorer (English: : Packet Internet Groper, referred to as: ping) command and route tracking (English: traceroute) command, for the Label Switching Path (English: Label SwitchedPath, referred to as: LSP) of Multi-Protocol Label Switching (English: Multi-Protocol Label Switching, referred to as: MPLS) ) ping command and...
