Yangyang, Just to elaborate on this, although Bono is a P-CSCF, it's probably not suitable for production deployment - it implements the required flows but has limited HA support, and also lacks SBC-style function (such as denial-of-service protection) that you might expect from a P-CSCF.
Clearwater's Sprout, Homestead and Ralf components _do_ have comprehensive HA support and _are_ suitable for use in production. Our experience is that production IMS networks make a separate selection for (or already have) commercial-grade P-CSCFs with more advanced redundancy support than Bono provides. In particular, we have tested extensively with Perimeta (http://www.metaswitch.com/products/sip-infrastructure/perimeta), and most of the production deployments of Sprout, Homestead and Ralf use it. I hope that helps - please let me know if you have any questions.

The registered client will typically notice this, and re-register itself. It can notice the registration loss in a number of different ways, e.g. it could be polling the Bono, it could notice that their TCP connection to Bono has gone down, or it could try to make a call and so notice that it needs to re-register. Any existing calls using the downed Bono are lost.

We are preparing to have 2 bonos, a Sprout cluster within one site for redundancy. We found the answer - "The failure of a Sprout node will affect any calls that are being set up, but will not impact any existing calls and registrations." at http://www.mail-archive.com/clearwater%40lists.projectclearwater.org/msg00974.html Can you tell us whether the failure of a Bono node will affect any existing calls and registrations ? Thank you and best regards, Yangyang _______________________________________________ Clearwater mailing list [email protected] http://lists.projectclearwater.org/listinfo/clearwater _______________________________________________ Clearwater mailing list [email protected] http://lists.projectclearwater.org/listinfo/clearwater _______________________________________________ Clearwater mailing list [email protected] http://lists.projectclearwater.org/listinfo/clearwater
