Tech info Time Direct & Remote
The Netnod Time Direct and Remote services provide a certified precise time signal generated by redundant time nodes using caesium atomic clocks, delivered over cross connect or MPLS VPN, and accurate to within 30 microseconds (Netnod Time Direct) or 1 millisecond (Netnod Time Remote) of UTC(SP).
These time services are the most cost-effective way to ensure your network time is accurate, robust and avoids the significant risks associated with using only GNSS.
The Netnod Time Direct and Remote services use state-of-the-art technology to guarantee accurate, secure and robust time. Our time services, designed to be easy to set up and use, provide:
- Redundant time nodes with caesium clocks
- SLA guaranteeing 30µs accuracy from UTC (Netnod Time Direct), 1ms from UTC (Netnod Time Remote)
- Secure connectivity over data centre cross connect or a Netnod IX Port (Netnod Time Direct) or over MPLS VPN (Netnod Time Remote)
- Customer Premises Equipment (CPE) with in-built oscillator to ensure stable, accurate time even if connectivity is disrupted (Netnod Time Remote)
- 24/7 Helpdesk/NOC
Redundant time nodes with caesium clocks
Netnod works with RISE, the national laboratory responsible for the Swedish national timescale: UTC (SP). We are trusted by PTS and RISE to distribute Swedish national time. Our time service is constantly monitored and checked both internally and by PTS and RISE so we can guarantee that Netnod Time is never more than a matter of nanoseconds away from Swedish national time. Our state-of-the-art time nodes use caesium clocks distributed in redundant pairs throughout Sweden to ensure redundancy.
Service Level Agreement (SLA)
Netnod Time Direct guarantees an accuracy of 30 microseconds.
Netnod Time Remote guarantees an accuracy of 1 millisecond.
Accuracy is measured as the maximum divergence between the time delivered by the service and Coordinated Universal Time - UTC(SP).
Secure connectivity
Netnod Time Direct
You can connect to Netnod Time Direct using a data centre cross-connect. This provides a direct connection to the Netnod switch over a physical port. If you are a Netnod IX customer, you can also connect over a separate VLAN on an existing IX port.
Netnod Time Remote
We deliver time direct to a Netnod CPE at your site using MPLS VPN. This is a fully managed service which guarantees accuracy within 1 ms of UTC. The CPE has an in-built oscillator to ensure stable, accurate time even if connectivity is disrupted.
