ABSTRACT:
A system for a global concurrent path computation in a communication network is disclosed. The system includes a path computation element communication protocol, wherein the protocol includes an indicator field indicating the global concurrent path computation, a global objective function field providing an overarching objective function, a global constraint field specifying at least one global constraint, a global concurrent vector field specifying at least one path computation request, and another indicator field indicating an outcome of a path computation request.
