Abstract: Systems and methods are provided for a computing system. The method of the computing system may detect and resolve circular references in preparation for validating the file. The method may include receiving a request, from a client, to validate a file. The method may further include, detecting, using logic and grammar rules, declarations, definitions, and references of entities in the file and resolving circular references in the file. The resolving includes, determining, as second entities, one or more of the entities that have respective references that lack preceding definitions corresponding to the respective references, and for each second entity of the second entities, prepending a declaration of the second entity before a reference of the second entity to create an updated file.

Abstract: Modifying a priority for at least one flow class of an application includes registering flow classes for an application with a SDN controller, determining, with the SDN controller, a priority for each of the flow classes based on other installed applications and network services on the SDN controller, modifying, based on an event, the priority for at least one of the flow classes of the application by mapping a priority key associated with the priority to a new priority value, receiving, from the application, at least one flow modification rule using a priority key as the priority, and validating the at least one flow modification rule against registered parameters of at least one of the flow classes of the application to determine a flow of traffic based on the priority.

Abstract: Prioritizing at least one flow class for an application on a software defined networking (SDN) controller includes registering flow classes for an application with a SDN controller, determining, with the SDN controller, a priority for each of the flow classes based on other installed applications and network services on the SDN controller, receiving, from the application, at least one flow modification rule using a priority key as the priority, and validating the at least one flow modification rule against registered parameters of at least one of the flow classes of the application to determine a flow of traffic based on the priority.

Abstract: In an example, a method is disclosed for redirecting a print job. The method includes monitoring status of a plurality of printers on a network, determining that a first printer of the plurality of printers that is responsible for a print job is not suitable for processing the print job, and selecting a second printer of the plurality of printers to process the print job. The method further includes generating a flow table modification message for a network flow corresponding to the print job to redirect the network flow to the second printer and sending the flow table modification message to a network device on the network.
