      SEL-5056

      Software-Defined Network Flow Controller

      The SEL-5056 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 is designed to work collectively with SEL SDN switches to provide a complete traffic-engineering solution for Ethernet-based 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. Provision circuits using network access control fields in Layer 1 through Layer 4 of the packet, giving you context-aware control of what conversations are allowed between any devices. 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—Proactively traffic-engineer your network, bringing more precision and predictability to critical infrastructure networks and improving failover times to less than 100 μs to support even the most demanding real-time control signals.

      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 automate commissioning and device discovery and create circuit provisioning. 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 guess work in testing scope by knowing exactly what communication circuits your network is configured to support and that all other conversations will be dropped with deny-by-default network access control. This results in a defined test scope and predictable and consistent network validation. You have confidence your network will perform exactly how you engineered it for as long as it is in service.

      Details

      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 through UDP or encrypted TCP Syslog.

      Change Management—Centrally manage your LAN as a single asset. Minimize disruptions when making network changes or when the system is scaled out.

      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 hosts.

      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.

      OS Support—Install the flow controller as an application on SEL Blueframe or as a service on Microsoft Windows Server 2016.

      Application Support—Interface with applications such as the SEL Flow Auditor.
