Abstract: A method relates to providing arbitrary and custom application traffic generation on network devices. The method includes identifying, via a network controller, an application associated with a network to yield an identified application, spinning up, by the network controller, a traffic generator in a container on a network device, wherein the traffic generator is configured to emulate traffic associated with the network device and the identified application and monitoring performance of at least one of the identified application in the network and the traffic generator on the network device.

Abstract: A system, computer-readable media, and methods are disclosed for searching a data stream for one or more regular expressions. The method can include receiving a data stream and a regular expression and parsing the regular expression to create a prefix portion and a suffix portion. The method can also include executing a first search of at least a portion of the data stream for the prefix portion using a first search algorithm, the first search algorithm being stored in a computer readable medium and executed by a processor. The method also include executing a second search of at least a portion of the data stream for the suffix portion using a second search algorithm, the second search algorithm being stored in a computer readable medium and executed by a processor. Further, the method includes determining whether the data stream contains the regular expression based on the first search and the second search.
