Context
The Union Minister inaugurated India’s first White Rabbit Technology-based Indian Standard Time (IST) Distribution Demonstration Network at the Regional Reference Standards Laboratory (RRSL), Jakkur, Bengaluru.
About White Rabbit Technology Demonstration Network
What is it?
- India’s first high-precision network for distributing Indian Standard Time (IST) through fibre-optic/Ethernet networks.
- Ensures highly accurate and synchronized time across critical sectors.
Developed By
- Legal Metrology Division, Ministry of Consumer Affairs
- In collaboration with:
- National Physical Laboratory (NPL)
- ISRO
- BSNL
- SEBI
How It Works
- Atomic Clock: NPL and ISRO generate the official Indian Standard Time (IST).
- Precision Time Protocol (IEEE 1588): Transfers time through fibre-optic/Ethernet networks.
- Automatic Synchronization: Devices continuously correct clock errors for precise timing.
Key Features
- Ultra-high precision: Synchronization accuracy below 1 nanosecond.
- Deterministic communication: Fixed and predictable data transmission delay.
- Highly scalable: Can connect thousands of devices over 1,000+ km.
- Open-source technology: Based on CERN’s White Rabbit Technology.
Applications
- Defence & National Security: Reduces dependence on GPS and protects against spoofing attacks.
- Financial Sector: Accurate timestamping for stock exchanges and digital payments.
- Telecommunications: Supports 5G/6G networks.
- Space & Quantum Technologies: Enables precise synchronization for advanced scientific applications.
- Power & Nuclear Infrastructure: Improves coordination of critical infrastructure.
