Embedded OpenFlow MPLS - Based Advance OpenFlow Inter-Domain Communication Proposal

As one of most promising and exciting future internet technology OpenFlow is attracting more and more researchers. However the methods and proposal of the inter-domain communication is still a key problem. In this paper, a EOF-MPLS methods is proposed to solve this problem. In this new technology, OpenFlow controller is responsible for the generation of the FEC and label binding algorithm. Users can use the operation system API provided by the OpenFlow controller to customize the details about the FEC and LDP, thus generate the FEC combined with labels. Considering the message reaching the boundary, Boundary OpenFlow Switch is responsible for identifying and forwarding packets to the other AS and it will complete the label replacement. The boundary OpenFlow is quite important that it should identify multiple protocols from different ASs, even some AS that has different internet structure such as NDN network structure. RSVP and traffic engineering can also be added to the process of FEC generation operated by the OpenFlow Controller. As a consequence, an entropy is used to evaluate the various affecting factors about the EOF-MPLS to the OpenFlow. Calculate the B-indicator to the A-indicator and the A-indicator to the total target one. The result shows that the most complicated A-indicator is the FEC and label combining while the most complicated B-indicator is the label number and TOS.
