Forwarding Commitment（FC）is a cryptographically signed code to certify an AS's routing intent on its directly connected hops. Based on FC, the goal of FC-BGP is to build a secure inter-domain system that can simultaneously authenticate AS_PATH attribute in BGP-UPDATE and validate network forwarding on the dataplane.
