RE: Peering - Benefits?

Hey Patrick...

Thanks for playing devil's advocate...  I am truly trying to cover both
sides of the discussion - technically it's what we want for sure but the
top of the food chain looks beyond just what a technical team wants to
do as I'm sure we're all plagued by sometimes ...

In our specific case, after factoring in ALL costs in an extensive
analysis - transit and peering end up very close .. peering being a very
slight amount above transit in our case.  At the end of the day it's
almost a moot point from a cost perspective (you can tell I'm not a bean
counter lol)

I would argue though that even with 4 transit providers (which we have
now), that peering is an excellent venue to take on - even for the
time/management involved.  Of course that opinion I can only speak for
our situation in that regard..;)

Appreciate your input - and I agree though that peering isn't for
everyone... definitely...

Take care,

Almost certainly.

But I'm sure the OP has a nice list to at least get him started of
peering benefits.  Interestingly, no one has mentioned the downside of
peering.  Just to play devil's advocate, allow me to mention some
"cons" about peering: If you drop all peering and push traffic to
transit providers, you can frequently get lower price per bit.
Picking 2/3/4 transit providers and committing large amounts to them
gives you flexibility, control, reliability, lowers your CapEx, and
lowers your network complexity which can (should) lower your OpEx.
There are others, but you get the point.

Just be sure to consider everything when deciding whether to peer.


P.S. Obviously, I think peering is better for the "network" I run, but
that cannot and should not be generalized to every network on the
