The SEL Software-Defined Networking (SDN) solution is Ethernet-based with better security, control, and performance than traditional networking. Break free and make a bold improvement in your substation local-area network.
Traditional networks use features like MAC tables, RSTP protocols, and cast types for many conveniences, including plug-and-play functionality. However, these features also make traditional networking vulnerable to cybersecurity threats, including MAC flooding and table poisoning, ARP spoofing, BDPU attacks, and more.
With SEL SDN, all network flows and backup paths are specifically defined in the controller, so there is no need for MAC tables or RSTP protocols. In addition, SDN uses traffic engineering to process forwarding behavior, rather than relying on “cast types,” which pose security risks.
Mission-critical processes demand mission-critical performance. The SEL-2740S fails over in less than 100 μs, compared to 10 ms for traditional networks. Because of our innovative approach to SDN technology, you get the proactive advantage of engineering all primary and failover circuit paths prior to commissioning. No more waiting for discovery or convergence times—your network already knows the next path.
With SDN, it’s easier to manage large amounts of network traffic than it is with traditional networking. The difference is that SDN eliminates unnecessary traffic on your network. Instead of a node broadcasting to all other nodes on the LAN, you can engineer specific paths and remove the extraneous. This capability ensures bandwidth availability and high performance in critical applications for anyone transitioning to the IEC 61850 standard.
Don’t wait until deployment to validate your design. Instead, use the SEL‑5056 Flow Controller to programmatically test the network implementation and validate all configurations and contingencies during factory acceptance testing. That way, you eliminate errors before going live and reduce commissioning timelines.
