Synchronize two production sites as if they were on the same local network

Context

Une entreprise disposant de deux sites de production devait synchroniser ses environnements IT en temps réel : applications métiers, données opérationnelles, outils de pilotage et systèmes de supervision. Les solutions IP classiques ne permettaient ni la latence attendue, ni la stabilité nécessaire pour garantir une exploitation fluide entre les sites.

A company with two production sites needed to synchronize its IT environments in real time: business applications, operational data, management tools, and monitoring systems. Traditional IP solutions did not provide the required low latency or the stability necessary to ensure smooth operations between sites.

Need

• Interconnect sites as if they were on the same extended local network
• Ensure low and stable latency, free from Internet routing fluctuations
• Provide a secure link suitable for critical traffic
• Simplify the network architecture between sites without multiplying tunnels or overlays

Solution Deployed

ielo implemented a LAN-to-LAN (E-Line) interconnection between the production sites over its fiber network.

The solution provides:

• End-to-end Ethernet transport, transparent for IT teams
• Controlled latency, optimized for real-time exchanges
• Simple integration into the existing architecture (VLANs, addressing, segmentation)

Result

The sites now operate as a unified environment with smooth, synchronized exchanges. IT teams benefit from stable, easy-to-manage connectivity without compromising performance or availability.

A LAN-to-LAN designed as a true extension of the local network, supporting seamless production continuity.
