Connection instability

Quote from: _CN_
Hi Maurice
you'll be back on when you disconnect and reconnect, thanks
Carl

Just done that.  Now having difficulty in keeping the session for more than 20 - 30 secs at a time.

Re: Aladdin being switched off 25/03

Connection seems to have stabilised again?  Seeing some odd times in tracert to plus.net.

I see from your RADIUS logs you seem to have had problems with keeping a connection prior to being put back onto the Aladdin trial, if this is going to 'muddy' the waters I'd suggest we remove you from the trial?

Re: Connection instability

The hop to your router initially had high pings too?
I got strange tracerts too. First try has large pings on hop 3. Repeat after a few seconds and again after a few minutes is normal.

When running traceroute at each hop the packet has to be punted to the CPU to be dealt with, the hop 84.92.5.98 is a Cisco 7609, at that time the router could have been doing large scale BGP convergence etc. (it also has transit and peering connections) however while its doing this the traffic through the box is not effected, which you would see by just running ping plotter.

Thanks for that explanation. I ran pingplotter for 5 minutes and saw the effect you describe; pings to hops 3 and 4 show large variations but values after that (throughput) changed by no more than 1ms.
