When looking into the figures you presented, some questions came up. Could you please have a look at them? Thanks. Kind regards, Francis. ------------- 1) Growth of routes and prefixes (1). The text on slide 5 indicates that the growth of the number of routes is partially explained by the impact of policy. Questions: * Which policies do you have in mind? Policies where more and more routes are announced to just 1 (or a limited set of) neighboring ASs? * Why do policies impact the growth of the routing tables but not the growth of the number of prefixes? 2) Growth of routes and prefixes (2). The text on slide 5 refers to 'more unique paths' and 'the impact of policy'. Question: * Are the 'more unique paths' a result of policies where more and more routes are announced to only 1 (or a limited set of) neighbor(s)? Or are there also other reasons for having more unique paths? 3) Growth of routes and prefixes (3). The figure on slide 7 shows the growth of prefixes and routes respectively. The figure shows that the growth of the routes is much steeper than the growth of the prefixes. Where does this difference come from? I understand that this difference does not come from having more alternatives to reach the same destination, since slide 5 indicates 'more unique paths'? 4) Route updates. The figure on slide 11 of your presentation indicates that there are 200- 2000 BGP route updates per 15 minute time interval. Questions: * What are your expectations for the evolution of the number of IGP route updates? * Could you provide some figures / references on todays number of IGP route updates and its evolution towards the future?
