I've been having an offline debate and wanted to take a quick
lithmus test...Mostly aimed at the folks who don't currently
peer at any of the 'nationally recognized peering points', but I'll
take answers from anyone...Ya'll are always so short on opinions. :-}
And we're always so fast to leap in with them, even when
we're still 200 messages behind, and not likely to catch
up before responding.
If someone presented you with the following options:
1) $X connect to a local peering point and peer with other
local/regional ISPs (MLPA) You retain current transit.
2) $X+$Y connect to a local peering point and peer with other
local/regional ISPs plus the host (a decent sized national
carrier) You retain current transit.
3) $X+$Y+$Z Purchase transit from the host, not including access
to the local peering points
Would purchasing #3 prevent or discourage you from purchasing #1 and
would purchasing #1 or #2 prevent or discourage you from purchasing
#3? How do folks feel about the concept of local peering points?
Much of this depends on the relative orders of magnitude for
X, Y, and Z. If X is relatively small compared to Z, I don't
think many people would even have to think once before purchasing
both #3 and #1, so long as there was no contractual limitation
on what other peering could be obtained when purchasing option #3.
Assuming a reasonable transit carrier already, #2 would definitely
preclude #3. There's greater benefit (IF you already have a good
transit carrier) in the redundancy afforded by hearing routes
from multiple sources, and having multiple outbound announcements.
If a peering session drops in #2, only that peer loses your
announcements. Case #3, peer drops, you lose everything at that
Local peering points are best used for just that. Exchange
traffic with others in your area. I don't think LOCAL exchange
points should be used as places to try to offload traffic destined
for far-reaching endpoints multiple hops away. That's what transit
carriers are for, and I think transit carriage of traffic out of
local regions is only going to increase, as the major players
stop seeing value at the local exchange points. It's a great
market for a company that wants to stop selling to end-users,
and who simply wants to provide transit pipes to regional and
local exchange points.
Of course, it's past 1am, and I'm just babbling, so feel free
to totally ignore this.
Comments, public or private, are, of course, welcome.
