The SEL-5056 Software-Defined Network Flow Controller is Microsoft Windows Server-based enterprise software designed to optimize software-defined networking (SDN) configuration and management for critical infrastructure. The SEL-5056 Flow Controller is designed to work collectively with the SEL-2740S Software-Defined Network Switch to provide a complete traffic engineering solution for Ethernet-based local-area networks (LANs). Traffic engineering with the SEL-5056 Flow Controller enables flexible configuration of each communications flow path and the ability to proactively engineer fault-tolerant networks, resulting in greater performance, improved reliability, and more deterministic packet delivery.
Create Stronger Network Security—Control exactly what is allowed on your network with deny-by-default architecture. The flow table configuration allows matching rules on fields in Layer 1 through Layer 4 of the packet, giving the system owner control of what is allowed at every layer of the network. Only configured flows are forwarded. SDN makes systems more cyber-secure by eliminating attack-prone networking features, like MAC tables, the Rapid Spanning Tree Protocol (RSTP), and cast types.
Improve Failover Performance—Predefine every network path, bringing more precision to critical infrastructure networks and improving failover times to less than 100 μs, two orders of magnitude better than those achieved with traditional networking technology.
Streamline NERC CIP Data Collection—Use the SEL-5056 Flow Controller with SEL Flow Auditor software to automate reporting of NERC CIP-007-6 R1.1—Systems Security Management, Ports and Services.
Reduce Downtime for Configuration—Configure the SEL-5056 Flow Controller in the field with all IEDs connected or configure it offline in a lab. Offline configuration provides flexibility and can reduce the downtime required for field installations.
Automate Configuration—Use Learn & Lock functionality to discover devices on the LAN and create a set of flows for current traffic. Learn & Lock enables supervised automation of network flow provisioning.
Manage Network Scalability and Change Management—Manage all network changes without affecting existing services and applications. All network additions and changes can be configured centrally and pushed out to configure the network of SEL-2740S switches.
Programmatically Test and Validate Your Network—Reduce deployment timelines and eliminate errors by using the SEL-5056 Flow Controller to programmatically test the network implementation and validate all configurations and contingencies prior to commissioning.
Secure Configuration—Provide situational awareness and strong cybersecurity through user-based access controls, encrypted communications, and detailed audit logging.
X.509 Certificate—Support secure, mutually authenticated communications between the switch and the flow controller.
Syslog—Enable log management for centralized automated collection of network events.
Change Management—Manage all network changes without affecting existing services and applications.
Holistic Network Visibility—View and manage your SDN switches as a single asset with near-real-time situational awareness.
Flexible Configuration—Configure network flows with or without network connections to IEDs.
Simplified Configuration—Automate the configuration of network flows with Learn & Lock.
Low-Latency Flow Setup—Establish new flows rapidly with low-latency flow setup times.
Interoperability—Work with an OpenFlow 1.3-compliant configuration interface.
Windows OS Support—Take advantage of high-quality, service-focused performance with Windows Server 2016.
Application Support—Interface with applications such as the SEL Flow Auditor.
