1. A path computation element (PCE) comprising:
a network interface for enabling communications over a network;
memory for storing executable instructions;
a processor configured to execute the executable instructions to:
establish communication between the PCE and at least one first child PCE, wherein the PCE is configured as a parent PCE to a first set of child PCEs comprising the at least one first child PCE, wherein each of the at least one first child PCE is responsible for a first domain in a set of first domains, and wherein the at least one first child PCE is configured as a second parent PCE to a second set of child PCEs comprising at least one second child PCE, wherein each of the at least one second child PCE is responsible for a second domain in a set of second domains;
receive domain connection information from the at least one first child PCE, wherein the domain connection information comprises a first set of domain connection information corresponding to the set of first domains; and
construct an abstract domain topology based on the domain connection information.
