Abstract: Technologies are disclosed for performing context-aware routing of traffic based on an application of a series of filters and/or selectors to determine an optimal group of interfaces for servicing traffic relating to a prefix. A traffic management control plane processes input data corresponding to aggregated telemetry data for a network by determining candidate groups of interfaces to service a network prefix and applies tunable filters and/or selectors to the candidate groups to determine a targeted group to use for servicing traffic corresponding to the prefix. The determined targeted group is mapped to the prefix in a mapping result, which is then provided to an actuator interface to control network devices to inject the new mapping into the network to control traffic according to the mapping.

Abstract: A system can determine by which path/tunnel an Internet destination can be best reached for a user with an IP address from a static BGP range. The system looks up the destination address in an egress map. This map can either specify a tunnel that should be used for encapsulation for static BGP, or (when tunnel is not present) cause the system to send out unencapsulated traffic, in which the traffic follows normal BGP routing on a border network.
