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: Disclosed are methods, systems, and non-transitory computer-readable media for determining a trust score associated with a user, comprising detecting entities near a user device operated by the user; calculating the trust score for the user based on a policy that incorporates data about the entities near the user device, the trust score being a score that is indicative of a trust worthiness of data received from the user device, wherein trusted entities near the user device result in an increased trust score, and untrusted entities near the user device result in a decreased trust score; and permitting access to a resource when the trust score is above a threshold.

Abstract: Systems, methods, and devices are disclosed for personalizing quality of service for network traffic. A user priority is assigned to a specific user and an application priority is assigned to a type of application. A header including an identifier is added to a packet from a client device associated with the type of application and the specific user in order to generate a modified packet. The identifier is based on a combination of the user priority associated with the specific user and an application priority. The modified packet is forwarded end to end through a network that is personalized to the specific user and the type of application by mapping a treatment policy to the identifier.

Abstract: Application performance can be simulated based on captured application-specific traffic flows through a managed network. Traffic flows may be captured across the managed network and associated with a particular application. The captured flows can be used to generate trend lines and models. The generated trend lines and models may be used to simulate application performance responsive to changes in network characteristics and provided to a user through a graphical user interface as a graph. The user may then adjust simulated network characteristics through the graphical user interface to perform various hypothetical network simulations.

Abstract: In an implementation, a method is provided. The method may include: receiving a sensor application by a network platform, the network platform comprising a processing module and a plurality of ports, and wherein a first portion of the processing module is allocated to an operating system of the network platform; allocating a second portion of the processing module to the sensor application by the network platform; executing the sensor application by the second portion of the processing module; emulating a port of the plurality of ports by the second portion of the processing module; and allowing the executed sensor application to interact with the operating system through the emulated port.
