Abstract: This article introduces the procedure tin which the authors develop MPLS system based on the ripe real-time operating system, and summarizes the experience in the procedure. It also discusses on how to develop MPLS and realize MPLS in hardware in the future. MPLS system has the functions of label forwarding, LSP hierarchy and penultimate hop popping.
