Network router having service card

Abstract:

In general, techniques are disclosed to facilitate communicating within computer networks. For example, a layer three (L3) router including a service card and an interface card may be configured to perform the techniques. The interface card receives a query from a network that sources communications in accordance with a plurality of models. The query may specify a customer device and one of the sourced communications, and request that the service card select one of the models for the specified sourced communication and the specified customer device. The service card further stores data defining a profile for the one of the customer devices. The service card may also, in response to the query, analyze the profile data for the specified customer device to determine the selected one of the models for the specified sourced communication with respect to the specified customer device.
