ADVA Network synchronisation

Are you in sync?

Today's networks stand at a crossroads. The rapid migration to packet-based technologies has created a critical flaw, one that could limit application performance and jeopardize your business. This flaw is the need for highly accurate timing information and assurance. It's a vital ingredient for a growing number of applications and one that is often overlooked in a packet-based network. Without it, your network cannot achieve its full potential, will lose its competitive edge and ultimately impact your bottom line.

Timing in financial trading

Operating fair, secure and efficient financial markets relies on highly accurate timing of every transaction. In the EU, the European Security Market Authority (ESMA) has defined transparency requirements including precision of timestamping for reported events. The Markets in Financial Instrument Directive (MIFID II) requires time accuracy of 100μs synchronized to UTC for algorithmic and high-frequency trading. A similar ruling was defined by the US Security and Exchange Commission (SEC) with Rule 613.

These stringent synchronization requirements can’t be met by the commonly used Network Time Protocol (NTP). New methods are needed to either improve the timing accuracy of NTP in legacy IP networks or distribute timing in a new way. Precision Time Protocol (PTP) is a more powerful and precise method of disseminating time information over packet networks. It combines hardware-based processing with additional timestamping in the data network. Time is not just transported over a network, network nodes also compensate for delays or even recover time by means of local oscillators acting as boundary clocks.

Find out more about highly precise PTP timing for financial networks and about the value of improving resilience with rubidium or cesium oscillators for extended holdover.
