Financial Sector Program

In a financial production network, time is not "as close as possible", but "must be consistent and traceable". When relying only on NTP, queuing jitter and path asymmetry across three layers and congestion can magnify deviations and tail risks to the millisecond-microsecond scale; PTP transforms source-to-end errors from uncontrollable fluctuations to budgetable, attributable, and manageable ones through hardware timestamps on the NIC/switching chip, boundary/transparent clocks, and (optionally) SyncE. PTP turns "source-network" errors from uncontrollable fluctuations into budgetable, attributable, and auditable quantities of work through hardware timestamps on NICs/switch chipsets and (optional) SyncE.
