Packet loss over network

Hi group,

We have a t1 through cavalier. Our blocks of ip address are in the 64.83.X.X network. The problem is that we are having a good amount of packet loss (10% at least) communicating between our office 64.83.X.11 (not real ip) and a server of ours at the hosting facility which is on the same subnet @ 64.83.X.59 (not real ip either.) A normal ping will only give about 2% or so packet loss, but a ping with a much larger packet size will result in greater packet loss. A trace route to the server shows that the packets that are routed stay in our network (64.83.X.X.) Does anybody have any suggestions on how to eliminate or decrease the packet loss?

Thanks!

Omg.. Packet loss within the network on a T1. And I thought cavalier couldnt get any worse. Have you read my thread on checking for packet loss and logging it? I am very intrested how this goes. Keep me up to date. Cavalier is trying to give me a T1 for the price of our current dsl to fix our packet loss problems. What they dont seem to understand is that the packet loss is within their own cheap ass network and misconfigured gateways so a T1 wont fix my problem. What has tech support said about your problem?

Mellow, I also followed your instructions on how to find out if you have packet loss, I downloaded pingplot and I have 10-24% packet loss. I'm also in the 64.83.XX.XX network. Edit: I dont have a dial tone. I'm thinking the cavalier servers got hit by that mydoom worm.

Edit: here's my packetloss test for today »/quali ··· /1293231

Do you have VoIP or POTS? If POTS, I don't know why DSL service should quash your dial tone.

pots is what I got, I can hear the dial tone as of today. This wasnt the case yesterday though. The thing that bothers me is that you never know when everything is going to mess up and if it does, and I'm in some kind of emergency, dialing 911 wouldnt work. Just a thought that went thru my mind.

You have just experienced what it would be like if your net/power went down with Voip.

Makes you wonder why is everyone in such a hurry to get rid of their pots line? Of course if your pots line is no better than that I would complain to the FCC.

I haven't spoken with tech support yet. Here are some links to my BBR linequality tests over the past few weeks.

Goto Cavalier with that info you have. Get them to run some tests on your loop. Im not sure about the SLA with cavaliers t1's but that kind of packet loss should not be happening on it.

Apparently the packet loss was being caused by me not having added the second subnet's ip to the fast ethernet nic on our cisco 1720. Now that I have 2 ips and 2 ip routes for the interface, the packet loss has seemed to clear up.
