OpenFlow is a de-facto standard programming interface between controllers and switches. How to enable the existing switches to support OpenFlow without losing their original forwarding capability is a challenge in the migration from traditional network to software defined network (SDN). Take Broadcom Trident series application specific integrated circuit (ASIC) switch as an example, an algorithm to map OpenFlow forwarding table entries into ASIC's ternary content addressable memory (TCAM) as well as traditional L2/L3 tables to augment the OpenFlow table's capability, was proposed. The feasibility and scalability of our solution was demonstrated with design, implementation and evaluation in physical switch.
