Techniques are disclosed for using arbitrary criteria to define events occurring within a network infrastructure, as well and techniques for detecting and responding to the occurrence of such custom events. Doing so allows a collection of networking elements (switches, routers, etc.) to perform a variety of distributed functions from within the network itself to respond to custom events. Further, because custom events are published across the network, multiple network elements can communicate and respond to the same event. Thus, unlike currently available event management systems, custom events (and responding applications) can be used to create and coordinate software defined networking within a common network infrastructure.

Supporting programmability for arbitrary events in a software defined networking environment

System, method, and computer program product to route data communications based on non-routing criteria, by receiving, by a network element, a data packet, identifying, in a routing table of the network element, a first route for routing the data packet, computing, by an application executing on the network element, a routing score for the first route based on one or more non-routing criteria, computing, by the application, a routing score for a second route for routing the data packet based on the one or more non-routing criteria, and upon determining that the routing score for the second route is less than the routing score of the first route, updating the routing table to cause the network element to route the data packet according to the second route.

Supporting arbitrary routing criteria in software defined networks

Methods and systems for providing customizable network device management are disclosed. In one such method, a user-created policy is received and registered on a network device, such as a router. An event identified by the policy is detected at the network device. In response, the policy runs on the network device and an action specified by the policy is performed. The policy can be prepared by a user of a remote computing device, uploaded to the network device, and registered on the network device. In various implementations, the policy can be provided in the form of a script or applet executable by the network device.
