The present disclosure pertains to systems and methods for automating the configuration of communication hosts in a software defined network (SDN) associated with an electric power transmission and distribution system. The systems and methods presented herein may utilize communication host profiles to specify various repeatable attributes and customizable attributes that may be utilized to configure the communication host and the SDN. In one embodiment, a system may comprise a communication host profile subsystem configured to select a communication host profile associated with a communication host. The host communication profile subsystem may configure the communication host based on one or more repeatable attributes and on one or more customizable attributes specified in the host communication profile. A traffic routing system may further configure a plurality of communication flows in the SDN based on the communication host based on the host communication profile.

Communication host profiles

The present disclosure pertains to systems and methods to identify high-priority traffic within a software defined network ('SDN') and to route such traffic through physically distinct communication paths. Such routing may help to reduce network congestion faced by high-priority traffic and increase the reliability of transmission of such data. Certain embodiments may further be configured to generate a failover communication path that is physically distinct from a primary communication path. Still further, certain embodiments may be configured to suggest enhancements to a network that may improve a reliability criterion.

Routing of traffic in network through automatically generated and physically distinct communication paths

The present disclosure pertains to systems and method for configuration of communication flows in a software defined network ('SDN'). In one embodiment, a system is operable to configure a communication flow between a first host and a second host. A mode selection subsystem is configured to cause a plurality of network devices in a network connecting the first communication host and the second communication host to transition between an open mode and an SDN operating mode. In the open mode, the network devices may discover a communication path between the first host and the second host. An analysis subsystem may receive information from the plurality of network devices information about the discovered path, and a topology discovery subsystem may be configured to create a communication flow corresponding to the discovered path. The communication flow may allow communication between the first host and the second host in the SDN operating mode.

Configuration of a software defined network

The present disclosure pertains to systems and methods for simulating data packet routing within a software defined network ('SDN'), visualizing the results of the simulation, and permitting a user to search the resulting simulation. In one specified embodiment, a system may receive from a user a simulation parameter associated with a packet to be simulated in the SDN. A packet based on the at least one simulation parameter may be generated. A response of the SDN to the packet may be simulated by identifying applicable traffic routing rules and identifying a subsequent destination based on the applicable traffic routing rules. A record of the subsequent destination may be added to the simulation result, and the process may continue until a terminating condition is satisfied.

Simulating, visualizing, and searching traffic in a software defined network

The present disclosure pertains to systems and methods for assessing reliability of communication links in a software defined network (SDN). In one embodiment, a system may include an SDN architecture subsystem configured to generate SDN architecture information and a bandwidth subsystem configured to generate bandwidth information. A latency subsystem may receive the bandwidth information from the bandwidth subsystem and may be configured to generate latency information using the bandwidth information. A failover subsystem may receive the SDN architecture information, the bandwidth information, and the latency information and generate a failover assessment and a failover route for the communication link. A reliability assessment subsystem may receive the SDN architecture information, the bandwidth information, and the latency information, and the failover assessment and generate a reliability assessment. A traffic routing subsystem may receive the reliability assessment and route data traffic to the failover route based on the reliability assessment.
