[SR-Users] Re: Sharing load between rtpengine servers

Hi, From the docs: "The balancing inside a set is done automatically by the module based on the weight of each RTPEngine from the set. The default weight is 1, if another RTPEngine should be used twice as often as the first one, one would specify the weight 2 for this server, for example." I am unsure as to what effect such large values as 99999999 might have on this arithmetic. It seems to me that if what you really want to accomplish is to evenly distribute calls between 22.22.22.22 and 33.33.33.33, with 11.11.11.11 only as a last-resort backup, then you should put the first two into one naive set without any weights, e.g. modparam("rtpengine_sock", "1 == udp:22.22.22.22:7724 udp:33.33.33.33:7724") Then put 11.11.11.11 into a set of its own: modparam("rtpengine_sock", "2 == udp:11.11.11.11:22724") By default, set 1 should be invoked: set_rtpengine_set("1"); rtpengine_{offer,manage}("..."); According to the docs, rtpengine_offer() will return a negative value if there is a failure of both: "The function will return true on success and false (-1) on various failures, like using rtp_engine_offer() on a SIP MESSAGE request or communication with rtpengine fails." Presumably, rtpengine_manage() does the same. Accordingly, you can do something like: set_rtpengine_set("1"); if(!rtpengine_offer("...")) { if($rc == -1) { set_rtpengine_set("2"); rtpengine_offer("..."); } } Exact details and your mileage may vary. -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800
