Growth of Exchange Points by Number of Participants Version 1. 0 December, 2001 Bill Woodcock Packet Clearing House
Research Spinoff from Peering. Coordinator Toolset Principal goal of the toolset is to assist peering coordinators with routine tasks while simultaneously… …gradually scrubbing the EP in-addr zones and RADB aut-nums and… …building a more complete, but anonymizable, database of peerings than can be published in aut-nums.
Dataset Monitoring several sources, notably in-addr zone updates and reachability. Updating the database once a day. email and since-last-login add/delete/change notification. Zone files contained non-uniform data (dates in more than fifty formats, for example) Pushing scrubbed zone files back to ISI. Input to World. Com for Peer. Maker.
Popular Wisdom 1 - Initial burst of founding members 2 - slow linear growth to “critical mass” 3 - exponential growth to capacity 3 1 2
Graph of Historical Data Following slide shows growth by number of peers for the eleven exchange points which currently have more than 25 peers and are utilizing the exchange point address space. . .
MAE-West ME ATM PAIX MW ATM Pac Bell New York Seattle Dallas Brisbane AADS Perth
No Exponential Growth Here With a few interesting exceptions, growth fits pretty well to straight lines. Clusters at 5/year and 12/year.
MAE-West ME ATM PAIX MW ATM Pac Bell New York Seattle Dallas Brisbane AADS Perth
Exceptions World. Com’s announcement of their intention to deprecate MAE-West and the opening of MAE-West-ATM show clear interaction, and a beneficial effect on the PAIX’s growth rate as well:

Requests from the Research Community? Currently supported queries: Total peers by month at exchanges which are above <threshold> from <date> to present Total exchanges by month for all ISPs which are above <threshold> from <date> to present Contemplating support for: Specific peer/date adds for selected exchange Specific exchange/date adds for selected ISP (? ) Currently returning results as HTML table or CSV, should soon have graphs as well.
