Re: Speed increase has also increased my ping

its very irritating that openreach wont allow a user to force fastpath on but they want to protect there network

 


Would you care to tell us why you come to that conclusion ? To put it another way How can the way that a connection is

 

configured have any affect on other users on the network ?

 

It cannot ,As for BT protecting their network,lol they don't care about their network, if they did then those who induce EMI and other types of interference into the network  could be disconnected from it,

 

the end user should be given the option of not having DLM run, and fastpath to be on for as long as the customer wishes, after we pay the bill, so should be given the choice, only problem with that would be support, most would be clueless and wouldn't know what you where asking them i'm unfortunately not making fun, hence why cheap deals

Re: Speed increase has also increased my ping

To put it another way How can the way that a connection is configured have any affect on other users on the network ?  I don't know the answer to that question; which is why I asked my question above.

 

I do know that there are many ways one misconfigured connection could affect other users of the network.  I can think of some, though I don't know if any of these actually applies, and if so how serious an issue it is.  Also, I know that there are likely to be many others I can't think of.

 

  1. Increasing sync and reducing interleaving increases the number of errors that need to be corrected on the upstream path.  This error correction adds burden to the processor in the cabinet.
  2. Increasing sync and reducing interleaving increases the number of uncorrectable errors.  This adds to the number of packets that has to be retransmitted.
  3. Risk of lots more disconnects/reconnects.  The cabinet may reasonably be built (hardware/firmware/software) assuming that connects and all the synchronization and other computation overheads it implies are quite rare.
  4. Wrong ip address.  Almost certainly doesn't apply here, but it is an example where one badly configured connection can have a huge impact on another user; and an example that most people wouldn't think of until they had once encountered it.
  5. ... all the other 500 possible reasons I don't know about.

 

So, as I said before, I think they are protecting service rather than the network; but I am not expert enough to know this, and I doubt that you are either.  I put the same question on the BE forum, as the level of expertise there (especially Tom/drsox) is much higher than on this forum, but have not yet had an expert reply.

 

p.s. Are you ricey66?

Re: Speed increase has also increased my ping

If you think about it in a logical way, the FFTC connection between your home and the FFTC cab , is on a 1:1 ratio, it is not shared in any way , so whatever the profile is set to is irrelevant to any one else on that FFTC cab exactly the same as DSL connections are to the termination point on the Dslam port , The only thing that could cause an issue is insufficient  fiber capacity from cab to exchange or the ISP's back haul /peering capacity

 

So the argument or suggestion that they are protecting their network  just isn't the reason for the way that they let DLM configure profiles, it saves them money  on having to provide properly trained support staff , and DLM usually works in the ISP's favor  customers will typically end up with a lower sync speed /IP profile and get switched on to interleave with sometimes a high degree of delay, and the customer isnt able to do much about it,

 

That would have to change before i would consider FTTC  Fiber on demand pending price per mtr may be an option though as that would  be free of dlm and interleave  as it would be FFTH,  i too play online FPS games and connect with people from all over the world so low latency and good peering is important to be ,more so than speed

Re: Speed increase has also increased my ping

I think you are probably right in your overall assessment: in fact I thought that from the start but wanted confimation.

 

However, you missed a step in your logical argument. If there were interaction issues, the most likely point of problem is the DSLAM itself.  That is doing a jugging act of multiplexing/demultiplexing a single fibre stream into lots of independent streams to/from the outgoing copper (hopefully).  If one (or a small number) of those streams is not behaving smoothly, it is quite possible that could impact DSLAM performance.

 

I'm not saying the DSLAM would be affected.  But I have seen analogous situations in routers, and in large back end servers, where one misbehaving client can seriously impact things for others beyond the normal effects of resourse contention.

Re: Speed increase has also increased my ping

Sadly still stuck with the higher ping, which is starting to annoy me now...

 

Just to make sure I am doing this right, do I need to completely power off the home hub to get a new session, or does clicking disconnect in the home hub settings work too?

 

Would it also be possible to replace both the home hub and the modem with a new router that included a VSDL modem, just so I can see what is going on under the hood and such?

Re: Speed increase has also increased my ping

yes disconnecting and reconnecting will work
yes you can get a new vdsl2 modem router like the draytek vigor 2750

Re: Speed increase has also increased my ping

I seem to be getting an unplayable ping now to a couple of game servers that I have been able to play on a couple of days ago...

 

Is this a network issue or just my line? I have tried pinging them from a couple of servers I own and it never reaches anything over 10ms.

I'm getting the same sort of thing. Looks like it's external to BT's network though:

Re: Speed increase has also increased my ping

Had an engineer at the house today to run various tests on my line, that apparently all came back perfectly fine. He still wasn't able to explain why the ping is higher now than it was.

 

He also left me with a Type A home hub to see if there was any difference coming from the Type B I was sent in the post.

 

Is there anything else I can try at all other than wait and hope it fixes itself? Given the choice I'd happily move back to my slower ADSL connection for the better ping...
