<DIV>Thanks Gordon for your response,</DIV>
<DIV>It helped me a lot ...</DIV>
<DIV> </DIV>
<DIV>I should have done this already, but the QoS issue was holding me back ... Actually, for now ... I'll start with just a backup box and test how it goes ...</DIV>
<DIV>I was looking for a kind of dedicated server hosting with a MPLS network that could give me a good level of QoS, but I didn't find it ...</DIV>
<DIV> </DIV>
<DIV>Thanks again,</DIV>
<DIV> </DIV>
<DIV>Marcelo</DIV>
<DIV> </DIV>
<DIV>P.S: If anyone has another point ... I would be grateful in reading your opinions</DIV>
<DIV> </DIV>

> points that exist in the UK (LINX, MaNAP, etc.) I'm not big enough for <BR>> that ... yet ;-) <BR>> <BR>> So I have routers and switches and connect into the ISP via a redundant <BR>> mechanism (VRRP). I can apply QoS in my own routers, so that traffic from <BR>> the Asterisk servers can be prioritised over the traffic from the LAMPy <BR>> type servers, however, without the co-operation of the upstream ISP(s), <BR>> you can't effectively apply QoS to the incoming traffic. (Fortunately in <BR>> my instance, incoming is so much lighter than outgoing, and their network <BR>> in not oversubscribed, so it's not really an issue) <BR>> <BR>> The easiest way to start, would be to simply place hosts inside another <BR>> ISPs network, and rely on them for "quality" transit - ie. make sure they <BR>> have multiple transit providers themselves, good power supplies, UPS, <BR>> generators, etc. and if they are good and don't oversell their bandwidth
<BR>> then for the most part you'll be just fine. Once you have several hosts <BR>> you might want to look at having your own router(s) and switch(es), but <BR>> this will depend on how the hosting company operates (and your budget!) <BR>> <BR>> Finding that hosting company where you live is the challenge though! You <BR>> need to ask lots of questions - can you get physical access to the <BR>> servers? is it within driving distance? do you have remote screen & <BR>> keyboard facilities? (or if they offer "remote hands" and if so, how much <BR>> do they charge?) How well do they connect to the world in general, and do <BR>> they charge separate for power or bandwidth (and is bandwidth in terms of <BR>> speed, or is it per bit pricing, or some combination of the 2?) <BR>> <BR>> Start phoning & emailling - how fast do they answer the phone, or return <BR>> email will be a good metric too... <BR>> <BR>> In the UK, London appears
to be power starved right now - it would appear <BR>> that bandwidth is virtually free, but you'll get charged per amp used! <BR>> Outside London you rarely have this restriction, but then bandwidth is <BR>> costly as it's got to be back-hauled to London (or Manchester), so "local <BR>> knowledge" is something you'll need to find out about. <BR>> <BR>> Good luck! <BR>> <BR>> Gordon <BR>> <BR>> _______________________________________________ <BR>> --Bandwidth and Colocation Provided by http://www.api-digital.com-- <BR>> <BR>> asterisk-users mailing list <BR>> To UNSUBSCRIBE or update options visit: <BR>> http://lists.digium.com/mailman/listinfo/asterisk-users </BLOCKQUOTE></body></html>
