Unlike commercial telecom networks based on internet protocol (IP), mission-critical communication networks rely on the synchronous digital hierarchy (SDH) standard. “The technologies used so far were very reliable, stable, durable, and also backward compatible and for a long time, IP technology was unable to meet these high technical standards, especially with regard to stability and security," explained OPW team leader Claus Kugler.
In 2020, NetCom BW embarked on a project to upgrade the existing network to the IP standard, in support of EnBW’s mission to diversify operations and provide new customer-centric solutions. The project envisioned a shift to the Multiprotocol Label Switching-Transport Profile (MPLS-TP) standard, which is a reliable packet-based technology to support IP networks and aligns with the modern communication needs of organizations today.
After a Europe-wide call for tenders and a comprehensive evaluation of eight offers, NetCom BW selected Hitachi Energy for this major network modernization project.
The evaluation included the setting up of a test laboratory at Biberach, with extensive engagement and involvement between the teams from NetCom BW and Hitachi Energy. This process helped validate the proof-of-concept and confirm Hitachi Energy’s technical proposal as the best suited for the project. The evaluation culminated in the signing of an eight-year framework agreement in January 2022.
