Hi,
I wonder whether anyone can answer either of these questions.
Firstly on 4G our data rates both up and down vary from time to time. So for the upload directing in particular I was wondering whether this rate is actually visible to the router, for example if the rate is 9 meg does that mean the router is actually transmitting at no more than 9 meg, or could it be transmitting at a higher rate with the limit applying somewhere with the network. The reason for asking is that I want to apply some upstream QoS which would obviously be easy if the router is the bottleneck. Otherwise I need to shape down to the slowest speed I expect to get.
Second question was with regard to carrier traffic management. I've seen speculation that the mobile operators lower the priority of what they call "tethered" traffic, and I've seen this blamed for poor performance using a 4G router. I wonder whether anyone had any factual knowledge of this, and if so whether there are workarounds. Personally I don't really think I'd call our performance on Smarty as "poor", but I wouldn't say no to any improvement. I've stuck a line into the LTE router config to re-write TTL, as that is something it's been suggested they look at to distinguish tethered traffic. I couldn't swear it's helped but it hasn't had any downside apart from making traceroute look a little odd.
Thanks, Tony S
