Accurate and precise time synchronisation is critical for numerous industries, especially financial trading, where even nanoseconds can make a significant difference. Distributing time accurately across wide area networks (WANs) presents substantial challenges, particularly in regions like Asia, where network links and local Global Navigation Satellite System (GNSS) sources of stable Coordinated Universal Time (UTC) may not be reliable enough. This is where the Lucky Packet filtering technique comes into play, offering a robust solution for achieving nanosecond accuracy in time distribution.
The Importance of Precise Time Synchronisation
The precision of time synchronisation can impact performance, security, and compliance in sectors such as financial trading, telecommunications, and data centres. Network Time Protocol (NTP) and Precision Time Protocol (PTP) are commonly used protocols for time synchronisation.
However, the inherent network latencies and packet delays over WANs can introduce unacceptable inaccuracies in high-stakes environments. This is particularly challenging in regions with less reliable infrastructure.
Challenges in Asia: The Need for Reliable UTC Sources
Asia's vast and varied network infrastructure often poses challenges for obtaining reliable UTC sources. The dependency on GNSS for accurate timing can be problematic due to signal obstruction, intentional jamming, or spoofing. Additionally, the extensive geographical spread can result in significant latencies and jitter, complicating the task of maintaining synchronised time across all nodes.
Introducing Lucky Packet Filtering Technique
Lucky Packet filtering is a novel technique designed to enhance the precision of time synchronisation over WANs by selectively choosing the most reliable timing packets from a stream. Here’s how it works:
Packet Selection: In a stream of timing packets, not all packets experience the same delay. Lucky Packet filtering involves monitoring the delays of incoming packets and selecting the ones with the least delay variability, termed as 'lucky packets'.
Statistical Analysis: The technique uses statistical analysis to identify these lucky packets. By filtering out packets that have experienced higher latency, it ensures that only the most accurate timing information is used for synchronisation.
Mitigating Network Jitter: Lucky Packet filtering significantly reduces the impact of network jitter. This is crucial for achieving nanosecond-level accuracy over WANs, as jitter can cause time deviations that are detrimental to critical operations.
Implementation in Asia's Financial Trading Sector
Implementing Lucky Packet filtering can be a game-changer for the financial trading sector in Asia, where microseconds and even nanoseconds can determine the success or failure of trades.
Trading systems can achieve greater precision, reliability, and competitive advantage by ensuring nanosecond accuracy in time synchronisation.
