Programmable path computation engine

A Path Computation Engine (PCE) comprising a processing system and memory configured for storing computer logic having instructions that, when executed, cause one or more processing devices to:

• store and manage a first set of objects including one or more Segment Routing (SR) policies and Traffic Engineering (TE) tunnels, the first set of objects representing custom behavior received from a network operator for defining intended characteristics of traffic flowing through a network;
• and
• store and manage a second set of objects representing one or more managed paths through the network, the one or more managed paths calculated by a TE technique using the one or more SR policies and TE tunnels.

A method comprising the steps of:

• storing and managing a first set of objects including one or more Segment Routing (SR) policies and Traffic Engineering (TE) tunnels, the first set of objects representing custom behavior received from a network operator for defining intended characteristics of traffic flowing through a network;
• and
• storing and managing a second set of objects representing one or more managed paths through the network, the one or more managed paths calculated by a TE technique using the one or more SR policies and TE tunnels.
