Abstract: This paper introduces an application-level load balancing model，it distributes the network traffic by the types of applications.The model divides the network traffic into two parts，the ordinary application traffic and the P2P application traffic，and distributes the ordinary application traffic by using static CRC16 algorithm.It divides the P2P application traffic into packet sets，and distributes the original traffic by using Hash mapping functions，and redistributes the flow bundles dynamically by the historical traffic based load balancing algorithm.The experimental results show that the model has an outstanding performance on feasibility and stability，and achieves the goal of application-level load balancing.
