When should a Device-Watchdog-Request be sent?

RFC6733

Options:

  1. always by timeout
  2. when there is no messaging
  3. when there is an error from the diameter-server

It is not clear from the RFC.

Solution

  • Each peer should send WDR (both client and server) every X seconds. Usually there is a configuration to adjust how much time to wait between WDRs. (It does not have to be the same time in the client and in the server)
