IDNet and latency

[Rik]

Hi guys

I've spoken to support about both your cases. Fozy, you're router can't be pinged, Kelevar yours is pinging from IDNet at 50ms. In both your cases, a modification order has been applied to remove interleaving from your lines.

Which ISPs did you migrate from?

[fozy994]

My router has been on all today :[

ADSL24

[Rik]

It's set not to respond to pings, ie it's in stealth mode.

stealth mode is a b*****d, you can never find the bloody thing to disable it!

[kelevra]

I also migrated from ADSL24 where interleaving was definitely off

[Steve]

My suspicion is that BT do it as a matter of course but that may be just paranoia.

Mine was off when I moved from Nildram, but it was on when I switched to IDnet. I had to ask for it to be turned off. I think it must be on by default.

[Gary]

Suddenly my latency has dropped, I did ask IDnet to make sure interleaving was not on as i have a 7150 profile with a 8128 sync on ADSL Max, with a 13.6 snr so a good line. Today my pings are much lower even though IDNet said interleaving was not on on my line at all. Yesterday it was 30ms these are todays results, bear in mind this is over wifi. my SNR has also dropped to 11.6 

Edit: Confirmed I have always been fast path, so maybe some Exchange work?

Ping has started…

[fozy994]

hm, be interesting to know what they did, your previous ping is similar to what we have with interleaving off...

[Rik]

Possibly a change of VP when migrating. It shouldn't have happened, but it can.

[Gary]

Well what ever has happened I'm not complaining 

[kelevra]

Will check mine when im home tonight and update you guys again. 

[Rik]

Toes crossed.

When I migrated (router was down 10 mins) the interleaving automagically got turned on.... damn you BT!

That said, my latency is pretty fine at the moment, far better than I remember it:

Code Select Expand

Ping statistics for 212.69.36.10:
    Packets: Sent = 20, Received = 20, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 8ms, Maximum = 9ms, Average = 8ms

Cripes. That is through two routers, a switch, and a server as well.

[kelevra]

This is why we are so confused as to why our latency has jumped so high

[esh]

Is this specific to anything? In my experience pinging your ISP or UBR or whatever is pretty much irrelevant to gaming pings unless your ISP ping is utterly dire with packet loss. Usually the packet size on the game server end is limited so you end up with much larger pings than you'd expect anyway, plus they are often in a different country.

Even with 8ms to idnet.net, my T2 pings are still 80-120 (packet size primarily) and GW and the likes generally hover around 200 (european servers).

[zappaDPJ]

Pings to European gaming servers completely baffle me. They seem to highlight major inconsistencies within the infrastructure. When Pipex were Pipex, pings through the French Telia network were consistently around 40ms for me. When I switched to Be they rose to around 120ms and with IDNet I'm getting around 180ms. However that said today my latency through the same network at peek time is currently 40-50ms which is extremely rare and very strange.

Pings to UK and even US based gaming servers are on the other hand superb. I rarely ping more than 35ms to any populated local server and usually it's half of that. Pings to US servers are usually 90-120ms. It seems somewhat odd that the World of Warcraft US realms ping lower than those in France.

I have no idea why the inconsistency, I do know that NTL users often have very low latency through Telia if they have a service at all   Perhaps it's something to do with network peering, I really don't know.

[Rik]

I would have thought it has to be peering or routing, Zap.

[zappaDPJ]

Forgive my ignorance, these are areas that I know nothing at all about, but who has control over these things? Is it something that's tweakable?

[Rik]

To some extent, the ISP chooses their peering points and routing, to some extent routing is also controlled by organisations like LINX, and also by the host servers. For example, Google (I think) was advertising its route on LINX when LINX had a problem, so people couldn't reach Google. Simon was able to route round LINX to get people up and running again.

[zappaDPJ]

Interesting, thanks Rik, I'm going to do some research on this

[fozy994]

Evening,

Came home from work today and got on the PC at 6pm, pings similar to what I've been experiencing in the past.. Just got back from the gym and jumped on the PC (10:30pm) and this is what I ping:

Much better!

Will report back tomorrow at peak times to see if it sustains, not sure what's happened here but it's good so far!

[Rik]

What are your speeds like, Fozy?

[esh]

While moving to DSL (from 56k) didn't always make my pings lower it did make them a lot more stable, and usually less packet loss. I've always had 100+ to anything in France when it comes to games. Also, don't play on servers in South America
