NkSIP Load Tester Sample Application

This Erlang application is a SipApp implementing a very simple SIP load tester.

Its purpose is to test NkSIP under heavy load, using transports udp, tcp and tls, and testing OPTION requests, REGISTER requests and INVITE + ACK + BYE call setups.

If offers two different test modes:

  • In the standard mode, it generates and sends the requests using NkSIP request generation functions.
  • In raw mode, it sends locally generated raw packets. This mode is useful to test a NkSIP in the same machine as an UAS server, without the UAC processing overhead.

Full test suites are available in nksip_loadtest:full/0 and nksip_loadtest:full/1. More fine-grained tests can be started with nksip_loadtest:launch/1.

The test is directed to a started NkSIP in the same host by default, but you can start this application and a listening server (using nksip_loadtest_lib:start_server/0) on another node and use the option host to send the requests to the remote node.
