Scenario Pauses Considered Detrimental #26

Open vindir opened 11 years ago

vindir commented 11 years ago

Currently when sippy_cup is building a UAC scenario where the server side submits the BYE it inserts pauses into the compiled scenario to match the rtp pauses created. This is actually detrimental to runtime execution of the sipp scenario because at load variations in timing can cause the scenario to be in the middle of a forced pause when the BYE is received. Since we are simply waiting for a BYE as far as the SIP flow is concerned, this isn't the ideal behavior of sippy_cup.

At a glance, I'd assume we may want to either automatically strip the pauses generated for RTP actions in UAC scenarios during this time or even better make them switchable in case the desired behavior really is to force the pause.

Thoughts?

Part of the problem here is that the pauses break when you are expecting to receive a BYE. If you are expecting to send a BYE then it's critical to retain the pauses.

This depends on #53.
