I would imagine some sort of Internet Authority on Routing. There are already quite a few authorities for other such things on the Net. But perhaps a better solution would be for everyone to register with a Routing Authority. We already require any one that wants to use a domain name to register, and if you want a block of IP space or a BGP number you have to register with ARIN. I realize there are registries like RADB and RIPE, but these don't seem to be used to their full potential. Some backbone providers still enter in route filters manually, which seems a little obsolete considering the number of routes being advertised. -- James Smith, CCNA Network/System Administrator DXSTORM.COM http://www.dxstorm.com/ DXSTORM Inc. 2140 Winston Park Drive, Suite 203 Oakville, ON, CA L6H 5V5 Tel: 905-829-3389 (email preferred) Fax: 905-829-5692 1-877-DXSTORM (1-877-397-8676) It's Unix or nothing!

Then, the lower tiers can do all the filtering they want, and still rely on default routing to send the packets to the backbone. It may not be the prettiest way to route traffic, but this would allow smaller ISPs to filter if they cannot afford buying bigger equipment to hold all the routes. Since the tier-1 guys are the glue of the Internet, they should be required to take everyone routes. -- James Smith, CCNA Network/System Administrator DXSTORM.COM http://www.dxstorm.com/ DXSTORM Inc. 2140 Winston Park Drive, Suite 203 Oakville, ON, CA L6H 5V5 Tel: 905-829-3389 (email preferred) Fax: 905-829-5692 1-877-DXSTORM (1-877-397-8676) It's Unix or nothing!

No need to go get a /19 if I can get my /23 globally advertised. : : The correlation with route flap should be re-examined. I suspectthat thisis no longer a driving force and is more than adequately compensatedfor byhaving flap damping parameters that scale geometrically with the prefix length.To state an obvious extension of these ideas: Without relief, space registrants are thus incented to (continue to)subvert thespirit of the allocation scheme in order to overcome its deficiencies.In doingso, a trend toward lower (shorter) "characteristic prefix length" iscreated bynetworks that would otherwise be suited by smaller allocations closerto theiractual occupancy. Metastability in interdomain routing is currently maintained by analgorithm [1]that suppresses oscillations to an acceptable level, deferring treatment of another "interesting problem" [2,3]. If distinctions between highlyaggregatednetworks and large, underoccupied ones are progressively obscured,strategiesthat inversely correlate prefix length with oscillatory period may be circumvented. Past experience [*] suggests that further detraction from the elusive"globalrouting stability" is more poignant and at greater issue to operatorsthan thecombined problems of address occupancy and table population. Indeed, it seems that a review of operational policy is in order. Regards, Andrew Bender Total Network Solutions, Inc. [1] C. Villamizar, R. Chandra, R. Govindan. RFC 2439. [2] K. Varadhan, R.
