Abstract

Some embodiments provide a method that generates different network measurements data (e.g., network topology, bandwidth estimation of different paths, etc.) for a pair of endpoints upon receiving a network administrative request (e.g., an application programming interface (API) request) or by other means (e.g., automatically and without intervention of a user). In some embodiments, the method is implemented by a network measurement agent operating on each endpoint and a centralized service component (e.g., web service layer) executing on a network manager machine (e.g., a controller) that responds to measurement requests. The network measurement agent probes the network periodically (i.e., in certain time intervals) or upon an API request that it receives through the network manager machine to gather the measurement data of a particular network topology between a pair of endpoints.
