Multi-domain software defined network controller

Abstract

A method and system for diagnosing a fault in a system. Operational state and configuration information is obtained from a plurality of components residing in a plurality of domains, the status and configuration information being based on a plurality of layers of a communication model. The operational state and configuration information are correlated and reformatted to create an end-to-end view of a network-based application; and a user interface configured to visualize the correlated and reformatted operational state and configuration information across the plurality of domains is generated, the user interface configured to present the visualized status and configuration information at each of the plurality of layers.

What is claimed is: 
     
         1 . A method for diagnosing a fault in a system, the method comprising:
 obtaining operational state and configuration information from a plurality of components residing in a plurality of domains, the status and configuration information based on a plurality of layers of a communication model;   correlating and reformatting the operational state and configuration information to create an end-to-end view of a network-based application;   categorizing one or more network flows based on a first network layer of the plurality of layers using application flow information collected from one or more network-based devices;   generating one or more level 2 graphical user interface (GUI) views based on the categorized one or more network flows;   correlating, for each network flow with source and destination information in the level 2 graphical user interface (GUI) views, topology for each network flow using protocol configuration information and route table information;   generating one or more additional graphical user interface (GUI) views based on the correlated topology; and   generating a user interface configured to visualize the correlated and reformatted operational state and configuration information across the plurality of domains.
