3. Path Energy Traffic Ratio API (PETRA)

This section describes an API to query a network about the Energy Traffic Ratio for a given path. It takes as input the source and destination of a path along with the traffic throughput between and returns the Energy Traffic Ratio in Watts per Gigabit. This is energy computed by the infrastructure that is dynamically part of the traffic path. This document only describes the API, the computation of the Watts per Gigabit to return is out of the scope of this document. The API is modeled following the OpenAPI Specification.¶
