In recent years, RDMA over Converged Ethernet (RoCE) provides high performance data transmission for Data center (DC). RoCE has excellent performance in lossless network, but when the network environment is unstable, the transmission performance of RoCE will decline rapidly. This paper proposes a DC network transmission technology based on network awareness. By monitoring the network status, the network status can be updated in real time. The transmission mechanism can be adjusted dynamically. In order to support the transmission in harsh environment, this paper constructs DC-TCP transmission based on Data Plane Development Kit (DPDK) TCP and DC-RoCE transmission based on RoCE, and designs a high-performance DC-TCP / DC-RoCE fusion technology framework. The simulation results show that the DC network transmission technology based on network awareness significantly improves the transmission capacity of the DC in complex environment.
