UDP RequestThis plugin adds UDP protocol support to JMeter. With this plugin you can load test DNS, NTP, TFTP, Boot servers and many-many other systems. Since UDP may be used both in one-way and two-way communications, there is option to wait for response and corresponding timeout setting. "Close UDP Socket" - the flag to close socket after processing request. Otherwise, the socket will stay open for the next iteration. "Bind Local Address/Port" - the options to manually choose which local IP and port should be used to send the request. Encode/Decode ClassMost of UDP applications use binary packet data, which cannot be directly specified in JMeter GUI. UDP Request use encode/decode classe (like TCP Sampler do) to convert request data from GUI into UDP packet data and response data back from binary to GUI-visible text data. There is embedded encode/decode classes:
Anyone can write his own encoder/decoder, implementing kg.apc.jmeter.samplers.UDPTrafficDecoder interface. Read Buffer LengthUDP Request reads response using buffer with default length of 4KB. You may override this value by setting JMeter property kg.apc.jmeter.samplers.ReceiveBufferSize in bytes. Example |
