Operationalization of Timekeeping

Ulrich Kohn - Technical Marketing

September 12, 2017

• Precise timing in other verticals

• … lessons learnt; finally creating a time-

as-a-service (TaaS) market

• Initial focus on regulator compliance

• … by optimizing financial appliances

• Hardening and preparing for more

stringent requirements

• … by resiliently combining multiple

delivery mechanisms with assurance

Overview

Synchronization is Key Evolution of Timing in Finance

Making best use of advanced technology and emerging services

• Base stations and small cells

• Transactional services in finance and other vertical markets

• Cable networks and emerging distributed access architectures

• Utilities, e.g., substations in power networks

• Precise synchronization for IoT and distributed processes

General Need for Precise Synchronization

Accurate Timing Is Mandatory

Increasing number of appliances require ultra-precise timing

Good Enough?

Trinity of Timing Excellence in Finance

PTP Delivery

Timing Assurance

Long Holdover Atomic

Clocks

GNSS as Reference

• Sync quality monitoring

• Packet delay performance

• Monitoring slave clocks

• Benefit from PTP performance

• Traceable to UTC

• Redundancy

• Ultra-stable clock

• Surviving PTP/GNSS outages

• Various holdover options

• Leverage PTP accuracy

• Protect investment with existing NTP clients

by using …

• NTP/PTP gateway

• Enhancing NTP with precise sync signal (1PPS)

• Upgrading legacy appliances with SFP GM

Until Jan 3rd: NTP to PTP Migration

Initial Approach

Benefit from better PTP synchronization performance in a cost efficient way
