Hi all.
Everything went very quiet after the VLan segmentation implementation(s) went ahead on Telstra's cable network.
I would mention that to the best of my understanding, it was a multistep and on-going upgrade, involving hardware and software -with the nodes under most pressure being upgraded first.
annectodally, I have to say that at some point there was a definate improvement (here in Wellington; Wainui) and as most people observed, the activity light on their cable modem stopped "strobing" which seemed a likely indication that ARP traffic had indeed been significantly reduced (over the network).
I definately noticed better stability, with less dropped games -but lately I've started dropping out again.
After a week or so of this, I ran some Ping tests against the default gateway (again) and it confirmed my suspicions. Every few minutes or so, I'd get a delay that was long enough that the Ping command would actually timeout. This was very typical of what was happening originally, and these intermittent timeouts definately correlate into being dropped from any online games I might try to play while the newtowrk is behaving this way.
Quite honestly, I pretty much just accept it these days, and go watch a movie, or do something productive.
But I'm just putting it out there -on my node at least, service has definately started to go down-hill again.
