Traditional Data Center Network (DCN) cannot satisfy large-scale networks and cloud-oriented infrastructure. Routing policies in traditional DCN complicate the forwarding elements and the topology management is inflexible in large-scale DCN. Protocol Oblivious Forwarding (POF) is a groundbreaking forwarding plane technology. In this study, we proposed two technologies of DCN. We designed extremely simple routing mechanism with POF. Forwarding elements of DCN can process packets easily using simple source routing protocol. Furthermore, we designed a cooperative topology management strategy to reduce redundancy of probe packets. We implemented our technologies in POF-based DCN and conduct some experiments. Results demonstrate that our routing mechanism can effectively simplify the forwarding elements and our topology management strategy can reduce the probe packets redundancy.
