An Analysis and Design of the Redirection Schema in ForCES

The idea of Forwarding and Control Element Separation has widely accepted by next generation network researchers, the regain attention of IETF (The Internet Engineering Task Force) ForCES (Forwarding and Control Element Separation) is the best proof. An IP tunnel-based redirection schema was proposed to solve the problem of routing protocol messages interaction between ForCES router and the external merchant routers. The technology of network virtualization is introduced to map network interface from ForCES FE (Forwarding Element) to CE (Control Element) which collaborating with the redirect schema.
