Nokia announced that it has delivered state-of-the-art IP/MPLS (Internet Protocol/Multiprotocol Label Switching) and optical technology and services to Swiss electricity transmission system operator Swissgrid for the management of its electrical grid. Swissgrid's transmission grid has a length of 6,700 km covering 140 substations.
The new "Grid Control Network" which became operational earlier this year, provides monitoring and switching for the electricity transmission grid, resulting in better alignment of power supply and demand, enhanced security and an exceptional level of reliability.
The solution is supporting mission-critical operational services such as Supervisory Control and Data Acquisition (SCADA) systems, Teleprotection, video surveillance via closed-circuit TV (CCTV), site access control and intrusion detection. This will allow Swissgrid to maintain the highest level of reliability, safety and security across the entire grid.
The network is also enabling business communications between electricity substations and Swissgrid locations for tasks such as office local area network (LAN) and voice over IP (VoIP) in a highly secure way.
In the turnkey project, Nokia implemented two IP/MPLS -based networks, one an operational network and the other a business communications network. They are both overlaid on an encrypted Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength Division Multiplex (CWDM) network, also from Nokia.
The IP/MPLS network features Nokia's 7705 Service Aggregation Router portfolio, with features tailored to support critical applications required by utilities as well as the7750 Service Router portfolio.The xWDM network layer, based on the Nokia 1830 Photonic Service Switch provides optical intrusion detection and on-the-fly low latency wavelength encryption for the operational and business communications network.
Patrick Langelaan, Head of Global Enterprise & Public Sector, Central Europe, Nokia
Our leadership in IP/MPLS and in agile optical networking allows us to deliver a robust, resilient and intelligent network for Swissgrid that will drive new efficiencies in their transmission network and meet the highest level of availability and security, which is essential in supporting smart grid applications.
