NEWS: The White Rabbit (WR) technology-based Indian Standard Time (IST) Distribution Demonstration Network was inaugurated at the Regional Reference Standards Laboratory, Jakkur (Bengaluru).

ABOUT

• White Rabbit (WR) is an open-source, Ethernet-based network protocol that enables sub-nanosecond time synchronisation and picosecond precision while supporting gigabit-speed data transfer.
• It is used to distribute highly accurate and synchronized time across large distributed networks.

OBJECTIVE

• Establish an indigenous, secure Indian Standard Time (IST) distribution network.
• Reduce dependence on foreign satellite-based time sources (e.g., GPS).
• Support the "One Nation, One Time" vision.
• Nodal ministryà Legal Metrology Division, Ministry of Consumer Affairs, Food & Public Distribution.

KEY FEATURES

• Uses ground-based fibre-optic networks for secure time distribution.
• Provides sub-nanosecond synchronisation and picosecond accuracy.
• Supports gigabit-rate data transmission alongside precise timing.
• Protects critical infrastructure from GPS spoofing and foreign signal manipulation.

SIGNIFICANCE

• Enhances the security and reliability of financial systems, telecom networks, power grids, defence, and scientific research.

Strengthens India's strategic and technological self-reliance in national timekeeping.
