Clock Synchronization in DCE
DCE’s Time model:
- Time in DCE is actually an interval.
- comparing 2 times may yield 3 answers:
- t1 < t2
- t2 < t1
- not determined.
Each machine is either a time server or a clerk.
- Periodically, a clerk contacts ALL the time servers on its LAN
- Based on their answers it computes a new time and GRADUALLY converges to it.
