RE: Why don't ISPs peer with everyone?

Content providers (e.g. Netflix, Hulu, YouTube) will always try to get their content serviced for little to no cost. 
The low cost, web-only plan isn't sustainable, and the amount of Netflix traffic around the globe is a good example; 
There's a lot of traffic that they aren't paying for.  The free market only works if entities self-police. But as has 
been expertly stated, there's no money in that.

I had an idea, I'm sure it's been said before:

If we actually had solid "Tier 1 vs Tier 2 vs Tier 3" thresholds, and we could come up with an agreeable metric, we 
might be able to minimize the impact of bandwidth hogs (sorry Netflix, pointing at you).

So, if you are a Tier 1, you are required to have at least 10 piers in 10 locations, 5 of which must be Tier 1 
providers. If you are Tier 2, that number is halved. It could be a combination of having the "status" of being a Tier 1 
provider, but the major benefit is a reduction of the diameter of the Internet. Even done by continent, this could 
offer enough parallel paths to help address (potentially) the cost of doing business.

I think we would need to have something similar for content providers. To reach Tier 1 status, you are required to have 
10 piers in 10 locations, which should cover a set multiple of your total bandwidth (1 TB if it is 500 GB, etc....) For 
reaching different tiers, they could receive a price break on the cost of Internet circuits.

There would also need to be a middle ground somewhere. Circuits would either need to stop being unlimited or have 
service thresholds. For exceeding, the content provider would be liable to pay X amount per Gigabit of bandwidth. This 
would then force Content providers to scale their business rather than relying on the upstream providers' upstream 
provider to do so.

Not perfect by a great margin, but I think something like that could help.

Sincerely,

I'd like to foster a discussion here to better understand this, not rile anyone up.  That said, what I see so far is a 
representation of those who do not recall the halcyon days before a rabid profit motive was the driving force behind 
ISPs.

Peering in it's original sense is/was free. It was a swap of traffic. That profit motive has created the phrase 
"settlement free peering" to refer to the original definition so it seems like the free swap of traffic is the 
aberration. The big ISPs used to seek to balance content hosting and the customer load to avoid having to pay for any 
sort of transit. AOL was known to acquire companies which had huge downstream traffic for this purpose.

Now we see ISPs waging an economic war with content providers wanting to find a way to charge, say, Google for allowing 
them to to pass their YouTube content along to the ISP's subscribers. This is the result of letting non-technical, 
profit-driven managers run the show and not the usually eager to cooperate network engineers who actually understand 
how this stuff works.

The problem here is that the closer you are to the end user, the harder you're getting screwed, and not in a good way. 
The very large ISPs are doing real peering, and charging smaller, end-user focused ISPs high transit rates so that they 
can't possibly compete on price with the inferior, customer-service-impaired ISP end-user offerings. The US government 
has declined to enforce any sort of rule which might require the huge ISPs to grant wholesale-type access to their 
physical networks (for better or worse depending on your POV) or examine any of this cartel-type behavior under the 
light of monopoly rules.

So please, short of socialism, and in light of the rampant legislation-for-sale culture in our government (how many FCC 
commissioners get jobs with huge ISPs?) how do we fix this?

Please note: I'm not advocating socialism. I might advocate regulation a la public utilities. There is universal 
agreement that the internet is "critical infrastructure." deregulating other utilities hasn't been uniformly 
successful, especially when measured from the consumers' point of view. Thoughts?

Peering costs money.  The transit bandwidth saved by peering with another
network may not be sufficient to cover the cost of installing and
maintaining whatever connections are necessary to peer.  Then there's the
big networks who really don't want to peer with anyone other than
similarly sized big networks...everyone else should be their transit
customer.

I manage a network that's primarily a hosting network.  There's a similar
hosting network at the other end of the building.  We both have multiple
gigs of transit.  We don't peer with each other.  Perhaps we should,
because the cost of the connection would be negligible (I think we already
have multiple fiber pairs between our suites), but looking at my sampled
netflow data, I'm guessing we average about 100kbit/s or less traffic in
each direction between us.  At that low a level, is it even worth the time
and trouble to coordinate setting up a peering connection, much less
tying up a gigE port at each end?

Anyone from hostdime reading this?  :)
If so, what are your thoughts?
