Because they have not charged you, the user .. they are paying for a finite amount of bandwidth .. and allowing a port to run hot is perfectly legal, BTW ..
I don't often quote myself, but when I do ..
There is a behind the scenes battle going on to control the Web .. and the telcos and CATV providers need to protect their profit margins ..
Instead of banning NF or YouTube or ______ (fill in the blank) .. ISP's would like to charge the content providers by paying for each additional port that needs to be opened when traffic starts filling them up .. and running a speed test with most widely available apps will not show you what your NF or other content is being delivered at unless it's using the exact same port .. but it will support the ISP's contention that "there is nothing wrong with your set" ..
Peering is the way this is being done .. essentially an arrangement between two bandwidth providers .. the companies that control the physical backbone of the internet .. in which they send and receive traffic from each other for free. .. traffic sent from one network to another is reciprocated without adding extra costs and hurdles. This makes the web more efficient and redundant because companies don’t need to build out a network to connect every single service to every person who wants to consume that service.
Think of a port as being the same as adding another lane to the freeway ..
If an ISP allows it's traffic to run hot .. or IOW, crammed with traffic and refuses to open another port, the end user will see a slowdown .. it has absolutely nothing to do with the content provider ..
Open Connect is essentially a cache .. which brings content closer to the ISP where it meets the Tier 1 provider .. and that's why Open Connect ISP's all seem to get general praise ..
This is no different than the fairly well known (on AVS anyway) tussle that took place with Verizon/Cogent back in 2010 ..
The Web is based on physical, real equipment .. when a port gets crammed, packets will drop .. that's just the way it is ..
