Sriram, To quote from the page you reference: "The data has been gathered using a single eBGP peering with AS 131072." We've got over 450 peers with multiple interconnects in 70+ locations, with many prefixes asserting reachability from multiple eBGP paths, and *millions* of eBGP-learned paths on many routers today -- and we're not even an ISP. Unless I'm missing something, I think this has some material impact on your numbers... -danny > the current global BGP system produces > Average Prefixes per BGP Update: 2.24 > Average BGP Update Messages per second: 1.13 > Average Prefix Updates per second: 2.53 > From this we can compute: > Average Prefix Updates per day = 218696 > > Now if we consider a BGPSEC island of 100,000 participating prefixes > (multiple ISPs form a BGPSEC island and there is BGPSEC between > them and also in each ISP's entire customer cone): > With 24 hour beaconing interval, we would have: > Prefix Updates per Day = 100,000 (seen at each BGPSEC router) > BGPSEC Update Size = 420B (for ECDSA-256) > Average Bandwidth Required = 3.89 kbps (averaged over a day) > > Does this answer what you were asking for? > > Sriram > > > > _______________________________________________ > > _______________________________________________ > sidr mailing list > sidr@ietf.org > https://www.ietf.org/mailman/listinfo/sidr
