Hi all, as I happened to discover recently, in at least two cases of fairly big ISPs IP addresses dynamically assigned to residential users are taken from pools regardless of the subscriber contracts. As a consequence, in such scenarios the same address could be quickly reassigned to users that, despite being topologically close, have very different provisioned bandwidth. So, while such reassignments are unlikely to happen to the peers participating in a swarm -- or at least are not going to have a significant statistical impact -- I can't figure any easy way to keep such information updated in relatively static maps some of the proposed solutions use (I can see how static maps AND dynamic queries can be used together though).
Now, we had several discussions about the usefulness of information regarding provisioned bandwidth in peer selection without reaching consensus, and honestly don't know how common such an address assignment policy is. Thus I would be very interested in hearing what people think about that, whether it should be something reflected in the requirements and addressed by the solution, or simply just ignored. -- Ciao, Enrico
