erratic latencey
« on: July 09, 2008, 08:29:00 PM »

Hi guys first post nice site btw

Having trouble with my orange connection, the ping has more then trebled  since they have installed ADSL 2 .

Not sure if this is a co-incidence because the only responce I get is that the problem is my end  :(

If I run a xp tracert the results are faverable, but if I monitor the connection with ping plotter all of the hops take it in turn to spike massively..

as you can see different hop big spike

From the traces youve provided, there doesnt appear to be any problems at your end.

Whilst I dont know for certain, it looks like Interleaving may have been applied to your line.
Your ISP may switch this off for you (I dont know if Orange do or not).  Getting interleaving turned off will possibly lop around 20ms off your time... certainly worth asking.

Theres no particular problem with the *'s.  It looks like that particular router is set not to respond to pings.  This could through up some weird problems with ping plotter.

However, the biggest problem appears to be at the peer point between Level 3 and the server you are trying to ping, this depends upon your ISP routing, but that particular point is outside your ISP control.

I'm way up in the northwest and Im able to ping that router in 15ms

Its L3. As usual.

Any gamer should shudder if they see L3 traces.

As its Orange (AKA France Telecom) you are stuffed because they're not going to use anything other than opentransit.net which with inexorable logic leads to them peering with L3 to get to Rackage (which is in Manchester - MANAP IIRC).

Only hope is that L3 break something, which isn't entirely unheard of.

Put your details in the adsl checker and let us know what LLU ISPs come back on the right hand side.  Most other ISP will use BTw IPStream, but we need to know what LLU ISPs are available before advising further.

Ok spoke to Orange tech support, they know less about interleaving than me  ;D (how is this poss  :-\)

Anyway gave up with them and went for the MAC code. There I found the most helpful lady I have yet spoken to from orange  :D She got a engineer there and then to look at my connection and agreed to get interleaving switched off at the cost of being put back to 4meg (Happy Days)..

Thanks for all your help guys hopefully my next post will just be a update, but nothing seems to ever be that easy for me  :D

Would like to know your isp recomendations just in case though .. ;)

From the choice of LLU providers available to you , then theres only really UKO that would look at turning interleaving off - and even thats a fairly recent development - link.
Rizla is with UKO so perhaps he's best commenting on what theyre like with Interleaving.

Well.. ok Tiscali would... but you did ask for a decent gaming ISP right? ;)

>> Was it the move to that LLU thing

yep - "Orange Available 30.05.08".  That looks like whats happened and your line is now LLU'd (ADSL2)

>> dsl Max enabled:  March 31, 2006

Means that you can go with any ISP that uses maxdsl ie Zen, Plusnet, Enta, etc etc

>> Distance:- Direct:    473 metres

Youre on a short line - you should get very good speeds.
Without seeing your linestats.. that indicates that you should get near full speeds with whichever ISP you choose to go with.  ( < 16Mb with Sky/UKo)


>> agreed to get interleaving switched off at the cost of being put back to 4meg (Happy Days)..

Ermm  if youre only 473 meters (direct) to the exchange you should get more than that?  You should get the full 8Mb.
Can I see your line stats please.

With UKO interleaving is turned ON on all ADSL2+ connections. No exceptions to the rule and they will not remove interleaving under any circumstances. Or so they said anyway :D

Routing with UKO (Easynet really) is frankly superb. They are far and away the best "connected" ISP I have used since the days that Adrian Mardlin ran Nildram's network and that is saying something!

Interleaving adds 15-20ms latency to my connection but that's a stable 15-20ms which isn't like network latency which is traffic dependent. I'd rather have that than Level3 any day of the week - which was a factor in me leaving Be too.

You should get up to the full 16Mb down 1Mb up sync with UKO (If thats the package that you go for).

>> Type : Fast

Looks like interleaving has already been removed.

>> Are you near to Rackage (manchester ) Im way dwn south

From the tracert rizla provided it all goes through telehouse-east in Docklands anyhow, so you should see similar to Rizlas.

YW.

There's a couple of other ISPs that could have been worth looking at too.. but obviously it depends what's available at your exchange - Hence why we got you to check 1st what is available, as it does vary from different locations.
There's also some good IPStream ISPs..  and the other consideration is what speeds your line is capable of.

You're lucky that you're not on a reasonable length line so should get good speeds.  This isnt the case for long lines and therefore for those users its not worth looking at the higher speeds.  Each line has to be judged by its own merits and what the user wants from the line.
