I didn't think your pingbox could do LCP ECHO as you weren't the ISP handling the L2TP session? Surely you're doing standard ICMP ECHO ?

I've been getting little tiny packet loss spikes on my graph for a while now (at least over a week) if you look above. they are tiny but consistent throughout the whole day but I haven't noticed any effect from them.

Ignore the spikes about 3pm and 1am, that was me restarting my modem.

My bad

AAISP don't use normal ICMP pings for this, they use LCP echo between their gateway FireBrick and the end user router: http://aaisp.net.uk/kb-broadband-cqm.html

I'm sure that must imply something relevant to the OP's problem but I'm out of my depth, so I'll leave it to those who know what they're talking about!

Bear this in mind: A packet loss is where the time to respond is greater than a defined parameter; A delayed packet is one where the response time is a lot greater than normal. There has to be a limit where a delayed packet becomes a lost packet.

I had a 40/2 connection for around 18 months and for ALL of that time I had a latency spike, from my normal average of 15ms to 150ms, every 45 minutes. Remember, the point plotted is the average of 100 pings.

My 40/2 Broadband Ping

Tried various suggestions from here and had BTs second line support working on it too - they could not find the reason or how to resolve it. We tried different modems (Huawei and ECI), various routers and more but it remained. Had the latency been a little greater I would have seen packet losses.

I moved from 40/2 to 80/20 and it just disappeared ... same modem, same router ...

My 80/20 Broadband Ping

Ultimately, does it cause you any problems? If not, it is one of those strange quirks you will have to live with.

I'm hardly an expert, but I understand that LCP is link control protocol, and your router and ISP communicate using this protocol and the PPPoA session is within this. Your TCP/IP communications (including ping) are then encapsulated within the PPP (point-to-point protocol).

So an LCP ECHO is well outside the TCP/IP network and only something an ISP can do, and definately not something ThinkBroadband as a third party website can do.
