and comparing the bandwidth information, the transmission delay jitter data and the packet loss data with preset thresholds respectively to determine a bandwidth network performance test result.
The following describes the method for testing and evaluating the performance of the broadband network specifically:
(1) testing the network performance: the network performance test comprises uplink and downlink bandwidth, delay jitter and packet loss tests, the bandwidth test is bidirectional, and the bandwidth test mainly comprises that after a client and a server establish three-way handshake by utilizing Tcp, the client sends data within a certain time and records the total data sent. The size of the bandwidth is equal to the total data sent divided by the total time sent. For the server, in the connection setup time, the total received data divided by the total time is the bandwidth measured by the server. The size of the MSS is obtained through TCP.
In the delay jitter and packet loss test, the client sends the UDP data stream in a speed mode specified by the client, and the delay between sending of the datagrams is calculated according to the speed provided by the client. The client may specify the size of the sending datagram in addition to that. Each transmitted datagram contains an ID number that uniquely identifies the packet. The server side determines the loss and disorder of the datagram according to the ID number. When the size of the UDP message is set to place the entire message in a packet of the IP layer, the message loss data measured by the UDP is the loss data of the IP layer packet. This provides an efficient way of testing for packet loss conditions. The testing of the datagram transmission delay jitter is completed by the server, the message data sent by the client contains a sending time stamp, and the server calculates the transmission delay jitter according to the time information and the time stamp of the received message. The transmission delay jitter reflects whether the transmission is smooth or not. Since it is a relative value, client and server side time synchronization is not required.
(2) The results are submitted to a database: and after the client side measures the result, storing the CPU peak value and the test result obtained in the test in a json format and sending the results to the database server. In order to ensure the safety of the database server, an intermediate layer is provided in the data server and the external interface of the database is closed. The middle layer is mainly used for receiving the test result sent by the client, recording the IP address and the current local time of the client, and inserting all the information into the database for background extraction and analysis.
(3) Background detection and analysis: the background server mainly acquires data from the database server periodically and analyzes the data. And comparing each index of the network layer through a threshold set in the early stage, finding the quality of the network performance of the user and sending an alarm. And performing Top statistics on the problems reflected by the user at the application level, finding whether the problems exist in the whole network or the exit, and early warning.
