Hello,

I am trying to develop a simple but fast application/daemon to take SIP invites, convert them into ENUM queries, send those queries to an ENUM server (likely residing on the same hardware as the daemon), get back an ENUM response and convert that to a SIP 302 (or other 300 level) redirect response.

 

Before developing this type of daemon, I just want to make sure about the expected daemon related to performance. If anyone has already done this type of work, please give some comments regarding the following performance issues, whether the following challenges are possible or not in real scenario.

 

  1. Daemon responds to an ENUM query in 0.7 milliseconds and answer 16,000 queries per second.
  2. Daemon should add less than 1 millisecond to that roundtrip so a SIP invite should get a 300 redirect within 1.7 millisecond.

 

I would appreciate if anyone can help me with relevant information. If the above challenges are not possible in real scenario, then appreciate for any near numeric figure which are possible to maintain in daemon.

 

Thanks

Nahid
