Hi Tibo,

what HB mechnism are you talking about? We use SCTP as the transport
layer protocol. It has Heartbeats. The Heartbeat timer is a
parameter of the SCTP implementation.

There is no notion of Heartbeat Message in ASAP or ENRP.

Best regards
Michael

Hi,

I am wondering how you implemented the heartbeat mechanism in your RSerPool
version. Here are some points I have in mind :
- on which principles (push, pull) have you based the implementation of this
feature,
- is there a heartbeat mechanism only between the PUs and the PEs,
- is this implemented only at the SCTP layer,
- what is the frequency of the messages sent and what is the overhead
introduced,
- what do you think about the efficiency of the heartbeat mechanism(s)
implemented, could an implementation of an heartbeat mechanism at the SIP
layer (running on top of RSerPool) be a solution to potential problems when
implemented at the RSerPool (SCTP) layer ?

Thank you.

Regards
Tibo
