Summary:
|
This Supplement describes the mathematical modelling and simulation analyses to support the development of ITU-T Recommendations on the transport of time over packet networks. The main purpose of this Supplement is to document this work, as it forms the basis for the requirements in the relevant Recommendations.
Both time-domain and frequency domain models and analyses are described.
Since SyncE noise accumulation results are needed as input to the simulation of time error accumulation, models and simulation analyses for SyncE noise generation and accumulation are also described. The modelling and simulation work described here is limited to steady-state behaviour, non-enhanced clocks, full-timing support from the network, and frequency provided by the physical layer by SyncE. Simulation cases that do not have these limitations are for further study.
