End-to-end circuit stitching

A system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable storage media configured to store instructions that, in response to being executed by the one or more processors, cause the system to perform operations, the operations comprising:
• obtaining lists of inter-Network-Element connections (inter-NE connections) between connection points of different network elements included in a network;
• obtaining lists of internal connections of the network elements included in the list of inter-NE connections, each list of internal connections corresponding to a respective network element and indicating connections within the respective network element, the obtaining of the lists of internal connections including populating missing entries of one or more lists of internal connections;
• generating, based on the lists of inter-NE connections and the lists of internal connections, a global list of connection points that correspond to the inter-NE connections and the internal connections, the global list including indications with respect to each respective connection point, the indications including:
• to which network element the respective connection point corresponds;
• whether the respective connection point is an input connection point or an output connection point;
• and
• a set of associated connections that correspond to the respective connection point;
• generating, based on the global list of connection points, a plurality of upstream connection chains in which each upstream connection chain is determined for a respective internal connection that has at least one upstream connection;
• generating, based on the global list of connection points, a plurality of downstream connection chains in which each downstream connection chain is determined for a respective internal connection that has at least one downstream connection;
• and
• generating a list of end-to-end circuits by combining the respective upstream connection chains and the respective downstream connection chains of each respective internal connection, each end-to-end circuit of the list indicating a respective chain of inter-NE and internal connections from a respective first terminal connection point to a respective second terminal connection point.
