Hi, I recently bought a Chicago Virtual Machine and am having some peering issues with my ISP. One of their major peers is Cogent, which seems to have wild spikes within their network(Yay cheap bandwidth. :roll: ). I was wondering if it would be possible to use the Internap Flow Control Platform to route around the Cogent network. Below is the route I currently take.

Code:
  1    <1 ms    <1 ms    <1 ms  DD-WRT [192.168.1.1]
  2     6 ms     6 ms     7 ms  10.85.128.1
  3     8 ms     8 ms     9 ms  d226-8-41.home.cgocable.net [24.226.8.41]
  4    11 ms    10 ms    15 ms  d226-6-134.home.cgocable.net [24.226.6.134]
  5    84 ms   203 ms   198 ms  te7-3.ccr01.yhm01.atlas.cogentco.com [38.122.17.9]
  6   167 ms   327 ms   198 ms  te7-7.ccr01.buf02.atlas.cogentco.com [154.54.24.221]
  7   203 ms   198 ms   207 ms  te2-8.ccr02.cle04.atlas.cogentco.com [154.54.43.117]
  8    23 ms    23 ms    23 ms  te0-5-0-6.ccr22.ord01.atlas.cogentco.com [154.54.43.121]
  9    25 ms    24 ms    24 ms  te0-5-0-7.ccr22.ord03.atlas.cogentco.com [154.54.44.166]
 10    21 ms    21 ms    22 ms  38.104.102.102
 11    22 ms    23 ms    23 ms  border5.po1-bbnet1.chg.pnap.net [64.94.32.10]
 12    22 ms    21 ms    21 ms  v-74-91-115-240.unman-vds.internap-chicago.nfoservers.com [74.91.115.240]

Trace complete.


Thanks.

Have you been seeing high latencies at the endpoint itself? Nothing you see along the path in the trace actually has any bearing on performance if the endpoint is not experiencing problems: viewtopic.php?f=25&t=4706

In most games my latency will fluctuate very quickly, sometimes accompanied with packet loss. Also in certain games there seems to be a noticeable delay between events. I rarely see high latency at the endpoint, though sometimes there is. Any idea what could be the cause?

You know, it's funny that one of my users from Vancouver was having the same issues.
The problem was in Seattle cogentco for us.
It seemed like when things hit cogentco the pings were going up big time.

Cogentco = baddie.

John, is it possible to skip cogentco?
Also is it possible to get an update if Cogentco is having some issues from their end as of late?

Usually when there is a problem over an NSP, it's not with the NSP itself, but with the ISP overloading its connection. More and more ISPs are using Cogent nowadays because it's super-cheap (we're talking sub-$1 per megabit) and its quality has improved significantly since the old days. Cutting it out completely would be a very bad idea overall.

Please have anyone seeing significant fluctuations or packet loss send us (directly) an MTR: viewtopic.php?f=25&t=4272. This will show us more accurately where the problem begins.

I thought Internaps FCP actively looks for the best routing and finds ways to go around network congestions.

IcEWoLF, that's correct, it does. It is limited in terms of what it can do on the inbound, however, because fundamentally the other end makes that choice.

With purchased InterNAP bandwidth, they don't actually use an FCP device, but a different system called "MIRO" (combined with hands-on monitoring), which is a bit more advanced.
