[arin-ppml] New Policy Proposal

Close but confused because the info that John Curran sent, although related to the TPIA framework, is actually from another parallel proceeding.

I'm writing another email to explain it better.

Thanks John.

For clarity's sake, I'd like to restate the situation in my own words and ask someone more familiar with it (Bill Sandiford?) to confirm or correct my statements.

Canada's CRTC has determined that ISPs should have access to cable companies' infrastructure sort of like how unbundling and CLECs impact the telephone companies in the US. The cable TV company won't be the exclusive Internet provider via the cable TV infrastructure.

CRTC has specified that the cable companies provide this two different ways.

Way #1: Layer 2 tunnelling, e.g. PPOE through the cable infrastructure back to the ISP. Works the same as we've been doing for a decade plus.
No special support from ARIN requested or required.

Way #2: Layer 3 "managed routers." Essentially, the cable TV company builds a logical overlay on their TCP/IP infrastructure for each ISP that wants access. The hitch is: the ISP (not the cable company) must provide the IP addresses that get plugged in to the cable company's infrastructure. Everywhere in the cable company's infrastructure where there's an address pool to be filled, the ISP has to fill it in a manner which makes for efficient routing and aggregation. Not gonna be doing that /32 thing all the way across the system, even for the folks with static IPs.

Problem! The ISP has to pre-reserve address blocks for the various areas within the cable company's infrastructure. The ISP then grows chaotically like all ISPs, more customers here than there. When it's time to expand his largest area, most of his addresses are stuck "reserved" for areas where he has few or no customers. Thus he doesn't meet the utilization target set by ARIN for more addresses. And he can't just withdraw and redeploy the underutilized pools because that ain't the way CRTC's TPIA is rigged.

How close did I get?
