HATI integration with Arista MetaWatch

White Rabbit is an ultra-accurate IEEE 1588 (PTP) implementation that achieves sub-nanosecond accuracy. Designed for use in avionics, telecommunications, space, defence and scientific facilities, White Rabbit has become the gold standard for time distribution within electronic trading networks. Leveraging the best of breed across two technology stacks with integration of the Seven Solutions HATI core (High Accuracy Timing IP) with Arista MetaWatch providing sub-nanosecond timestamping
in conjunction with accurate, precise and reliable timing.

Seven Solutions sets new record for long distance White Rabbit High Accuracy time over fiber link

The White Rabbit link covers an approximate distance of 1,350 km (840 miles) and was deployed in collaboration with Optiver US, a financial company, to connect Chicago and New Jersey trading locations. This link is formed by six long-distance White Rabbit hops using WR-Z16 and WR-ZEN TP devices connected by a combination of DWDM and SyncE-compliant transponders over a public telecommunication fiber network.

Inter-datacenter accurate time synchronization in a metro area using commercial telecommunication networks for the Spanish Stock Exchange.

The finance industry is being pushed by MIFIID II regulation to register most of its operations with timestamps legally traceable to a Coordinated Universal Time (UTC) reference with 1 microsecond granularity and 100 microseconds maximum divergence. This poses a challenge for the sector, since the most commonly used solutions to provide time in the industry do not comply with the requirements.
