Sorry for the confusion. Let me clarify. We are interested in a number of questions: 1. Can we assume loosely synchronized router clocks in the Internet, or we have to make absolutely no assumption about router clocks at all? 2. If the router clocks are indeed loosely synchronized, what is the granularity we can assume? Particularly, we are interested in whether we can assume router clocks are synchronized within 10 minutes. 3. It's always possible that a router's clock goes wrong. In practice, how often does this happen? Thank you for all the replies. Best Regards, Xin Liu On 9/17/07, Randy Bush <randy () psg com> wrote:
