RE: [Asterisk-Users] Optimum online-upload throttling confirmed.
Been there, done that... I was talking to a high level tech for an hour... Basically, they calculate the need for throttle based on the length of time a modem is busy, not the amount of data that is transferred. So for example, asterisk not involved, If I view an axis camera feed remotely, after about 2 minutes the entire network lags. Even though it's only going 10-20k/second, it's the constant traffic that does it. It's a cable thing, probably since they have so many modems up on their nodes now... A year ago the node was nice and empty...

Hello All, I was recently fighting with an optimum online connection in NY. I finally got in touch with someone that confirmed they are throttling my upload connection. I just wanted to make everyone aware of it, so if you have problems if your ping times jump erratically, this could be the cause. Their suggestions were, although you can upload a lot, do not do it constantly. They do not want any constant outgoing connections. Even on business class, they do throttle. All business class primarily does is allow port 25 to pass. Now I am going to look and see if I can get a decent upload speed dsl or something to correct this problem. You might try traffic shaping before going to your ISP. Being that ping is erratic though, is evidence that it may not help. I believe LARTC has some information for you there. -Brendon ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I know they watch for people doing peer to peer file sharing and throttle those connections quite severely, but I wasn't aware that they do general throttling.

I have a friend who uses Vonage (on a ComCast cable modem, not Cablevision) and many times when I talk to him, the voice quality is bad. The reason is the way that _all_ cable companies deploy their data services (it's a CableLabs DOCSIS standard that they all use). Remember that cable modem networks are shared media. The downstream to the cable modem is a broadcast and each cable modem listens for traffic to it. No latency problems here. However, on the upstream, each cable modem requests permission to send and then the cable modem termination system (CMTS) grants it a token to send. Very significant latency and jitter problems here for VoIP. For their own service offerings, the cable companies solve the problem by identifying the VoIP call flows during the call setup and scheduling the media packet stream (RTP packets) grants in advance. Therefore, when I use my Cablevision optimum voice line, my RTP packets are given special priority and the latency and jitter problem is solved. But if you are using Vonage or your own Asterisk box, your RTP packets are treated the same as any other data packet. Not good for VoIP quality. And the problem becomes very bad when the network gets busy. The bottom line is that I wouldn't try to use any cable modem service (ComCast, Cox, Time Warner, Cablevision, doesn't matter) for a VoIP service where voice quality really matters a lot.
