Nothing at all if you squint and look at the left half.

Cheer Carl, Yet again I'm obliged and indebted for your patient elaboration (albeit I was personally reasonably familiar with the concept) and eagerly await your concise explanation when someone (other than me) asks "What about dual token bucket rate shaping"? ;)

Sort of reminds you of some Technical Support Forums doesn't it? :p

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Do VM use ERBA and hence require dual token buckets on downstream? Pretty sure they don't on that score, just yet!

I guess you're referring to dual token on upstream. Easy enough - I defer to this Google site:

https://sites.google.com/site/amitsc...affic-policing

Though of course the CIR on VM's tiers is zero - dual token is more built with services like VoIP in mind where the cable modem has to implement DTB to ensure it behaves well with a UGS VoIP service flow rather than allowing buffers to be overwhelmed by high bandwidth BE service flow traffic :)

Though at a high level I work in technical support. Don't give me any more incentive to be yet more jaded :)

I am suffering from high utilisation in the evening when my download speed drops from 100mbit to 28mbit, when this happens i notice that part of my upstream power levels are different on each channel when i believe they're normally the same.

For example my current power levels are 39.75, 39.75 after a reboot which i think looks normal but last night they were reading 40.25, 41.75.

What is the significance of the numbers being different after the decimal point as i thought the reason was mentioned here by someone but i can't find the post?

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

There is no significance. Having slightly differing power levels on any channel is normal. Different frequencies experience different levels of attenuation and interference.

I have noticed over the last few days I am getting a little bit of packet loss it appears

It seems our long lost friend is back. I notice a hump across my graph that perfectly coincides with midnight and appears on a few local CMTS graphs also:

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Got a hump starting as well.

I have the same hump, still ongoing:

This one starts at 11pm though.

If I had to hazard a guess, I would say Virgin Media are carrying out network maintenance… If indeed it is happening within the Virgin Media network, it could be a transit provider sitting between Virgin Media and Think Broadband.

This isn’t what we have seen previously, this isn’t a link becoming congested… Instead it looks like Virgin Media or a third party are shutting down a link, traffic is then taking an alternative route, which happens to have a higher latency.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

There isn't a transit provider sitting between Virgin Media and Think Broadband. Not as far as I know anyway.

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

No hump in Abingdon

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Presumably because NetConnex is peering directly with a number of global Tier 1 providers including LINX,LONAP, AboveNet etc :p

Re: Think Broadband Ping Monitor Results (POST YOURS)
 

Well, whoever else NetConnex peer with is rather irrelevant given they have public peering directly with VM anyway.

And technically LINX is not a global tier 1 provider, it's an exchange that providers interconnect at. Neither is LONAP.

Getting really annoying witt this crap now.
