Synchronisation for Financial Networks - 1

Synchronisation for Financial Networks Timing Solutions for Financial Networks In today’s financial networks, one critical challenge is the need for time synchronisation accuracy for all connected elements. IT organisations in financial institutions are becoming mandated to keep accurate records of all transitions such as when a transaction was initiated and completed along with the real-time date and time stamps for each transaction. Packet based timing and synchronisation techniques are used to achieve accurate time at each connected key part of financial networks. Rakon offers a unique range of OCXOs ideal for time synchronisation in financial networks. Precision Time Protocol (PTP) for Synchronisation The price and trade related data for a reported financial instrument is exceeding many million per second on global stock exchanges. Therefore, the precision required to correctly identify the messages is in the order of 100s of nano seconds. The order of processing of the incoming records is maintained and trading decisions are taken based on time stamps. The multi-cast market data messages are time stamped when leaving the exchanges to make sure every one gets the same time stamp. Packet based timing technologies are becoming popular in financial networks for accurate time stamping. Traditionally GPS Oscillators for PTP Solutions in Financial Networks PTP Grand Master solutions translate clocks traceable to primary references to timing packets. These systems use stable reference clock sources to protect themselves from network synchronisation failures using holdover mechanisms. with IRIG-B solutions which provided high accuracy solutions required expensive and dedicated hardware. First generation packet based synchronisation solutions such as Network Time Protocol (NTP) offered lower precision. Precision Time Protocol (PTP) is fast being adapted for time synchronisation in financial networks because of its ease of deployment and management over existing infrastructure. For time synchronisation in financial networks, Rakon offers OCXOs to support the frequency control and time synchronisation networks at the core, edge and metro level. on packet base networks. The packet based implementations introduce varying loop bandwidths depending on the network scenario and short and medium term stability of the oscillator at each such loop bandwidth becomes important.

Rakon’s OCXO Performance Rakon has characterised various types of oscillators under changing environmental conditions for the loop time periods relevant to Packet Networks MTIE and TDEV performance at various loop bandwidths. Rakon performs extended tests on the holdover phase movement performance of its OCXOs and offers devices that have holdover performance of a few ^s across the temperature range over 24 hours. Rakon has a wide range of OCXOs that economically fit holdover requirements of 1 to 10 ^s across 8 to 24 hours. The graphs below show examples of OCXO MTIE and holdover...
