In collaboration with Westdeutscher Rundfunk (WDR), Germany, LOGIC media solutions has successfully completed a demanding routing and orchestration project within WDR's RegioNet. This initiative marks a milestone for WDR as RegioNet has evolved from a traditional IP-based network into a Software-Defined Networking (SDN) environment. In this new configuration, RegioNet is not only more stable but also gains operational flexibility. Furthermore, it takes a significant step toward preparing this critical WDR infrastructure for the future.

WDR RegioNet connects 16 of the broadcaster's locations for contribution and distribution, integrating not only production lines, for exchange and network interconnection, but also the delivery to broadcasters and various distribution channels such as streaming, DAB+, FM, DVB-S2 and DVB-T2.

With the project's completion, WDR RegioNet's IP-based network is now orchestrated and monitored using Nevion VideoIPath. The VideoIPath orchestration platform for media is developed to combine network orchestration with broadcast control functionality. The system is vendor-agnostic and scalable, and supports hybrid SDI and IP workflows.

As well as orchestrating RegioNet's Arista switches, VideoIPath also controls the Lawo PowerCores, which act as routing devices and gateways for the audio signals of WDR radio stations. VideoIPath can access the PowerCores via Lawo’s Ember+ interface for smooth, direct control over their functions.

To guarantee a high level of fail-safety, LOGIC has installed the VideoIPath software in a Docker cluster, as a way of orchestrating workloads – containers are scheduled across various nodes, and networking is configured from there. This use of containerization and virtual instances makes the VideoIPath installation hardware-independent and also allows enough redundancy for reliable operation.

LOGIC has closely supported WDR as a service and consulting partner throughout each project phase. From the initial consultation through the network setup and implementation to migration, the focus was on ensuring that the WAN team of ‘WDR Programme Distribution and Networks’ could operate RegioNet securely and independently and implement transmission requirements and adjustments flexibly. This comprehensive support enables WDR to operate its RegioNet efficiently, but with a focus on the future. www.logic.tv
