Okay, i've updated my version up to CVS and it's fine. I am making SER wroking for CDRTool evaluation version thus i had to have the RADIUS accounting compiled in. SER is a great peace of software. I have another question regarding to Your experience with billing. I've connected radius with mysql and SER. I have good accounting that gives me call duration, callee number, caller number and almost everything i want. cdrtool makes it readable for humans :) My question is - what rating (not … [View More]

LVS, load balancing, and stickness was ==> Re: [Serusers] more usrloc synchronization
by Greger V. Teigre 29 Apr '05

29 Apr '05

After my last email, I looked at ktcpvs and realized I ignored a couple of things: ktcpvs only supports tcp (http is obviously tcp-based, but I thought it supported udp for other protocols). I don't know how much work implementing udp would be. Here is a discussion of SIP and LVS that I found useful (though not encouraging). http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.services_that_dont_w… Paul: I'm starting to get really curious on the standard LVS components used for your … [View More]stickiness! I'm not aware (also after searching now) of an LVS balancing mechanism that allows correct stickness on SIP udp...! And I found other too who are looking for it: http://archive.linuxvirtualserver.org/html/lvs-users/2005-02/msg00251.html My understanding is that ipvs must be extended (according to the developer) with a call-id based scheduler and that this work has several people willing to fund development, but that this has not(?) started yet. The problem is that ipvs is based on ip header analysis and extending the hashing algorithms to also include payload-based analysis is not straight-forward. g-) > With regards to stickiness: Have you looked at ktcpvs?

Is the vm module deprecated? I noticed it's not in 091. If so is there an alternative? Searching the mailing list and not finding much regarding rhis. Maybe I'm crazy? :-)
