I have a question about how to use ntp in a long linear network. Assume there are 50 nodes with the one most in the West having GPS, and every node running ntpd: node1 --- node2 --- node3 --- ... --- node50 GPS
Which approach to synchronization would be better in terms of the time accuracy in nodes: 1. configure 'server node1 ...' in nodes 2, 3, ..., 50; or 2. use manycast for automatic client / server self-organization? Approach 1 seems to me to lead to inferior accuracy due to increasing distance between a client in nodex and server in node1, where routing in nodes node2, node3, ..., node(x-1) would add to jitter. Yet we would have one node stratum1 and all others stratum2, it would seem... I would think approach 2 with manycast would end up in smaller offsets (if any) between clocks, but would lead to clocks of stratum 16, 17, ..., 50, and I am not sure how ntpd would react in node16, node17, ..., node50. Could an expert please offer a comment on which approach would be preferable? Sincerely, Jerzy. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
