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.
Traffic-Engineer Each Communications Flow—Take control of how the network performs by configuring physical and logical circuits, or flows, for each application. Network administration focuses on the application requirements instead of network limitations. Traffic engineering enables the system owner to decide how packets are forwarded by the deny-by-default architecture, regardless of the Ethernet type. This enables the system owner to have control of every Ethernet frame allowed on the network and how it is transported. The SEL SDN solution includes the SEL-2740S Network Switch and the SEL-5056 Flow Controller.
Create Stronger Network Security—Control exactly what is allowed on your network with the deny-by-default architecture of the SEL-2740S. The flow table configuration allows matching rules on fields in Layer 1 through Layer 4 of the packet. This gives the system owner control of what is allowed on the network at every layer of the network. Only configured flows are forwarded. These rules are proactively engineered using the SEL-5056 Flow Controller.
Ensure Critical Applications Operate and Perform to Specification—Predetermine how the network will respond to failure states by proactively configuring primary and failover communications flows for each application. With network convergence times of less than 100 μs, failover times are two orders of magnitude less than those achieved with traditional networking technology.
Simplify Network Design With Topology-Independent Traffic Engineering— Design topologies and communications flows based on the application requirements instead of optimizing for dynamic control plane administrative protocols, such as the Rapid Spanning Tree Protocol (RSTP). Simply configure the communications attributes of a specific protocol session and the forwarding path instead of requiring MAC addresses and virtual local-area networks (VLANs) within the constraints of RSTP. This eliminates the additional network-required tags or labels and simplifies operations. With the removal of RSTP, the network bandwidth is free for operational data and removal of RSTP topology design restrictions. Traffic engineering identifies the key attributes that make a unique communications flow, configures the specific circuit that flow should be forwarded through, and assigns any change action set along the way.
Centrally Manage and Monitor Networks in Near-Real Time—Enhance system awareness using centralized network monitoring, and extend network visibility to the substation. The SEL-5056 Flow Controller provides comprehensive monitoring of all path- and packet-level network statistics of each communications flow, giving increased awareness of network health and status.
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 during factory acceptance testing.
