In the real world (or at least in my world) we use undersubscribed internet connections that come with a service level agreement (SLA) that guarantees that the jitter, delay, and packet loss with be within defined parameters in the service agreement. With most DSL and Cable you will not get a SLA, with the cheapest T1s you might get one, but the only penalty to the ISP if they do not meet is a

That "program" will be detected by your ISP within a day or so, determined to be a virus, and your service will get disconnected...which n turn will not help your latency or jitter at all. VoIP can tolerate a fair amount of latency; latency over about 100ms is heard as a perceptible delay resulting in a connection that appears to be half duplex. Jitter, on the other had, is the real

Hi Brian, The Atom1-buildbot buildslave has been failing for a few days but I don't think the problem lies in the LLVM/Clang source. From the logs at http://lab.llvm.org:8011/builders/clang-atom-d2700-ubuntu-rel/builds/13632 (and newer builds): ******************** TEST 'Clang :: Driver/x86_features.s' FAILED ******************** Test has no run line!

All, Thank you for the prompt and useful answers to my questions. I had missed references in 5.7.6 which would have answered some of the points. As Bill pointed out a newer version of acrobat would help, but the Sun system here is still running 5.0. (An oversubscribed sysadmin). Then I could have searched and at at least avoided the most trivial. All three comments were different,

Hi all, I am having some fun with traffic shaping, and have run into an interesting situation. Here is South Africa, most internet links are heavily oversubscribed, which means that in most cases the local link is _not_ the bottleneck, and shaping on the local link does not help that much... Does anybody have some tips on shaping such links? How can you get interractive traffic if you

I''ve been recently testing the Xendemo CD and I can say that Xen is awesome. I''d like to start deploying it initially in some development/testing servers. However the limitation of the max memory of 800MB or so per virtual machine is a show stopper for many applications. Are there plans to raise the limit to something higher (like 2GB or so)? How difficult would it be?

Seeing as IPV4 is near it's end of life (http://www.internetnews.com/infra/article.php/3915471/IPv4+Nearing+Final+Days.htm), I'm curios as who know whether everyone is ready for the changeover to IPV6? Is anyone using it in production already, and what are your experiences with it? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog:

Hi All, I started a 501c3 (not-for-profit) organization back in February 2011 to deal with information archival. A long vision here, I wont bore you with the details (if you really want to know, e-mail me privately) but the gist is I need to build an infrastructure to accommodate about 2PB of data that is database stuff, stored video, crawl data, static data sets, etc. Right now in my testing of

Hello guys, Does anyone has an Asterisk server hosted off-site ? Like in those data centers that do web hosting in dedicated servers ? Is there a hosting company that has a special plan to host voip services like this, or usually is hosted in those dedicated servers like the ones I asked above ? What about QoS ? I know that most (if not all) are connected to their switch through a
