So there's even less of a notion of "connection". > And in fact the point of the paper is using PTP with the end result that > the intra-farm "errors" should (it's four years later maybe they are) be > in the nano-seconds. Yes, that's true. The OP wanted to know about NTP clusters, so I guess there are two lessons here: - either do what NIST did and ensure that your NTP cluster servers are so closely synced with each other that they are indistinguishable by clients; - or ensure that your load balancer ensures an association between clients and servers which persists for long enough (given the poll interval, probably to be multiplied by a safe factor, e.g. 3).
