Abstract :
A PCE-based strategy for LSP re-optimization in flexgrid optical networks is experimentally validated. A front- and back-end stateful PCE architecture is deployed, wherein automatic and coordinated operations (e.g., computation delegation, database synchronization, etc.) are demonstrated using PCEP and BGP-LS protocols.
