ECN-Based MBAC algorithm for use over HAIPE

This work addresses the development of an ECN-based MBAC algorithm for use over HAIPE. The proposed MBAC resides at the red enclaves, but leverages the ECN, which is defined in RFC 3168 and can be activated at the existing black routers. With these MBAC capabilities, ad-mission control policies are generated at the red enclaves to react to the black core congestion without the need to pass information from the black core to the red enclave, which would violate HAIPE requirements. The presented technique adheres to HAIPE 3.1 specifications and creates no extra overhead traffic or breaks the red-black boundaries defined by the HAIPE standards. The advantages of the capability are demonstrated through a hardware test-bed.
