Network quality testing tool based on virtual extensible LAN

Abstract

The invention discloses a network quality testing tool based on a virtual extensible LAN; a client end and a server end build vxlan connection; the client end forms data packages according to the RFC 5357 standard; a first NTP server adds a series number for each transmitting data package in each time; a first VTP terminal uses a vxlan protocol to package the data package; a second VTP terminal checks vni fields in the data package, uses vni to distinguish the Lan and parse the data package, and sends the data package to a second NTP server in the Lan according to inner layer IP and MAC addresses; the server end turns and returns source object IP / MAC to the client end in an original path. The testing tool uses RFC5357 as exploitation and measure standards, can test network link conditions without using a fixed port, can simultaneously support physics and virtual link detection, can send data packages one by one without using link bandwidth, is high in data package transmission efficiency, high in measuring precision, uses bidirectional measurement, and a graphical operation interface is coupled.

Description

technical field [0001] The invention relates to the technical field of network link quality detection, in particular to a network quality testing tool based on a virtual scalable local area network. Background technique [0002] Network links are like real roads, and there will be unexpected situations such as congestion. Therefore, a network quality testing tool is needed to monitor and detect network links, that is, tools such as network probes. The network probe can detect the network very well, and feed back information such as network delay, packet loss, jitter rate, and bandwidth through a specific algorithm. [0003] At present, the existing network quality testing tool, that is, the network probe, has two schemes: 1. The condition of the network link is detected by sending data packets in batches at one time, and this scheme is prone to transmission when a large number of data packets are sent at one time. The problem that the data packet fails and the program itse...

Problems solved by technology

[0003] At present, the existing network quality testing tool, that is, the network probe, has two schemes: 1. The condition of the network link is detected by sending data packets in batches at one time, and this scheme is prone to transmission when a large number of data packets are sent at one time. The problem that the data packet fails and the program itself does not find it, and the problem that the packet sender has relatively high requirements for machine performance; when using the above method to measure the link status, you must bear the risk of the link being blocked by the probe tool; 2 , By sending data packets one by one to detect the status of the network link, although this sending method is more accurate, but the efficiency is relatively low

[0004] Moreover, the above two detection methods are calculated through the data packets constructed by themselves, and do not correspond to network standards such as RFC. There is no unified standard, which has a negative impact on the specification of detection technology.

Although the existing probe tools are relatively complete and can complete many different types of function detection after some slightly complicated configurations, there are generally still the following deficiencies: they can only be used for physical link detection, and cannot support a certain virtual link It can only send packets to a certain port of the machine for measurement. When the port that needs to be measured by the peer technology is occupied, the test will fail and the link will be unavailable, which will affect the judgment of network maintenance personnel. It is more complicated and easy to use. The network link is blocked; the packet sender uses the kernel state protocol stack to send packets, and the speed is slow; most of them only have a command line interface, which cannot match the operable graphical interface; most of them are one-way measurement, and the measurement accuracy is not enough
