So you want to stream up all the data?

Is that 500kbps limit you set or ISP enforced? 

 

My ISP (LTE based) surprisingly prioritises most streaming traffic such as YouTube (and Netflix I think) during peak time.  My monthly limit is 750GB, however, that cap is strictly enforced.  Go over it and it is a eye popping €50 per GB, which I've heard people getting hit by.

 

To give an idea of traffic prioritisation, the following is a YouTube "Stats for Nerds" screen playing 4K, which should be impossible at the speed TestMy reports on the right:

Ah, was wondering. :D

 

I think there's just one ISP in Ireland that throttles to 1Mbps.  The rest either cut the connection (e.g. LTE and wireless ISPs) or charge for excessive usage. 

 

I checked the Windows Resource Monitor while playing a video forced in 4K mode:

I see that YouTube now streams over two simultaneous connections, as those two 74.125.97.18 connections were going steady until I stopped the video. 

 

The following is a trace route to this IP:

According to the TCPIPUTILS website, the last 4 ISPs shown belong to Google.  172.30.199.50 is a non Internet routable IP, so is within the ISP.  This indeed means that either Google has servers within the ISP or has peering with Google that is given high traffic priority.

Interesting.

I've since setup squid, not that this will help with streaming, but every little bit will, caching 500Gigs should do something over long term. Each user gets 750k .

 

I've yet to work out whether squid will do throttling if :80 / :443 are not explicitly blocked on the network, or if traffic shaper will continue to do it.

 

Here's a quick screen of streaming youtube @ 480p, (where 'thecave' is a local domain) also notice the same net as yours? I know what they are, but I don't know what other than SSL through google this will be accomplishing so...........
