Sally Floyd - Questions about Round-trip Times (original) (raw)

• ROUND-TRIP TIMES (HOPS, NUMBER OF ASes) OF PACKETS?
  For packets on a particular link, each packet could be assigned an estimated round-trip time, a number of ASes for the end-to-end path, etc, based on the IP source and destination addresses for that packet. For packets on a particular link, what can we say about the distribution of round-trip times, or of the number of hops traversed, or the number of ASes traversed, or number of continents traversed, or (this is harder) the number of congested links traversed?
  [Example: For link X, can we say that most packets/bytes stay on that continent? Or that most packets have a minimum round-trip time of at least S seconds? Or that most packets on that link during this period of time traverse more than one congested link on their path from source to destination?]
