Application descriptive language for network gateways

An apparatus, comprising:

• a plurality of physical network interfaces;
• a processor coupled to the plurality of network interfaces and configured to execute a process;
• and
• a memory configured to store the process executable by the processor, the process when executed configured to:
• determine performance characteristics of the plurality of physical network interfaces;
• receive an application descriptive language-based description of performance requirements of a virtualized application for execution by the apparatus;
• select a particular one of the plurality of physical network interfaces for use by the virtualized application during execution, based on the performance requirements of the virtualized application and on the performance characteristics of the plurality of physical network interfaces;
• and
• cause the virtualized application to use the selected physical network interface during execution by the apparatus.

A tangible, non-transitory, computer-readable medium storing program instructions that, when executed by a device in a network, cause the device to perform a process comprising:

• determining, by the device, performance characteristics of a plurality of physical interfaces of the device;
• receiving, at the device, an application descriptive language-based description of performance requirements of a virtualized application for execution by the device;
• selecting, by the device, a particular one of the plurality of physical interfaces for use by the virtualized application during execution, based on the performance requirements of the virtualized application and on the performance characteristics of the plurality of physical interfaces;
• and
• causing, by the device, the virtualized application to use the selected physical interface during execution by the device.
