30M : Le3 6 - network access denied?

[Chrysalis]

you got the same square patterns at 4am and just after 8am and again at 10.30am.

seems those for rest of day your utilisation is too high to show it. I think its only apparent if utilisation low enough.

fair enough i see. any idea what would cause that though?

Well I now know why vmng300's have better jitter. Its nothing to with processing power but rather that they have lower queue's for upstream packets, in affect they given higher priority than other modems for timeslots. This can be a downside tho because if there is enough congestion and the max delay isnt high enough then there will be packetloss. Delay is better than packet loss.

Its only my guess as to why this jumps up and down tho, it seems to jump downwards less when utilisation is higher on the port. Also if utilisation is high enough even when its down the jitter will be as high as when it jumps upwards anyway. My guess is the modem operates differently in how it queues packets when under enough load. I think another way of putting it I think the queue size is dynamic, it possibly switches between a low bandwidth mode with a small queue and a high bandwidth mode with a large queue (higher jitter).

on my tbb graph the modem gone into a low queue mode and can see its 50% higher max latency than last night at 10pm and its only 2pm.

seems also speedtest.net even with proxy is not close to 3mbit now either.

protocol shaping starts at 5pm so am curious if that rising blue hill drops off at 5pm.
