Re: [SR-Users] Kamailio multihoming

Alex, thank you for you hints. Load distribution is more of priority to me. I think low TTL might be a solution. But what can be done to keep Kamailio in sync on geographically dispersed servers?

Which is the big priority for you? Redundancy can be done in many ways, from simply having two servers (perhaps with database replication if extensively DB-backed) that the callers roll over on transaction timeout, to SRV records, to HA setups with Heartbeat/Pacemaker/OCF/etc. Sometimes disk-level replication with DRBD is also a part of that, depending on the requirements. Geographical load distribution is generally done using some sort of selective DNS query answers + low TTLs, or by using a stateless load balancer (less resource utilisation than stateful) to distribute calls across multiple stateful proxies in various places, or by statically assigning customers to chicago.us.sip.myprovider.com. -- Alex -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/ _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
