Embodiment 1

[0026] see figure 2 , before the fault and Qos detection process starts, the user needs to configure the parameters needed for automatic detection of faults and Qos values. The parameters required to be configured are as follows: The parameters that must be configured for Qos detection include the source interface or IP IP address, the number of packets sent for each detection, the waiting response time of each Ping packet, the time interval of each detection and the threshold parameters of Qos; the optional specified parameters are optional parameters of the standard Ping command;

[0027] The threshold parameters of Qos include the threshold parameters of the packet loss percentage, the threshold parameters of the average delay time, and the threshold parameters of the average jitter time.

[0028] After the device is running normally, the detection of the network is started regularly, and the time of each detection is also determined. According to the configured parameters...

Abstract

The method comprises: according to the QoS parameters, automatically sending Ping request message at main and standby interfaces or at main interface on time, and receiving the Ping response message; making calculation for each parameters of QoS in the Ping request message in order to decide if there is failure in network and there is a parameter of QoS over the threshold; if there is a network failure or a parameter of QoS over the threshold, then making a changeover between the main and standby interfaces, and giving a alarm to the main interface.

Description

technical field [0001] The present invention relates to a method for Qos detection in a communication network, in particular to a method for Qos detection for communication between routers, three-layer switches or all NGN (next generation network) devices that can output IP interfaces in the field of IP bearer networks, belonging to data communication field. Background technique [0002] In the field of data communication, Qos refers to the quality of service (Quality Of Service), and generally uses indicators such as packet loss rate, jitter, delay, bit error, and disorder to measure the quality of an IP network. Qos is generally determined by the devices and links on the transmission path. Congestion of routing devices may cause packet loss, delay, and jitter (delay and jitter will occur without congestion); simultaneous transmission of the same session on multiple paths may cause Cause disorder; the transmission link will cause bit errors and packet loss due to interfere...
