Fat-tree structure is widely adopted in data center network for its high bisection. There have been lots of researches of load balancing in fat-tree topology network. Static ECMP is easily trapped in local optimum and centralized scheduler causes large overheads. In this paper, we proposed a ProAcive Pod-Based (PAPB) load balancing scheme. PAPB is based on SDN architecture, thus gets a global congestion aware of network. Proactive and pod based flow instantiation reduce the number of flow entries in an OpenFlow switch and decrease the overheads between control plane and data plane. Simulation shows that our PAPB scheme greatly reducing the packet loss rate and the queue length compared to ECMP and RR.
