摘　　要：为提高应用交换系统的吞吐量和数据转发性能,提出一种基于计算芯片和交换芯片三线互连的应用交换系统。通过计算与交换芯片板级直连的方式,避免数据信号的多次转换,降低网络交换延迟;通过将二三层网络交换卸载的方式,增加四七层应用交换的带宽利用率;通过跨内核数据直取的方式,提升应用数据的转发处理能力。压力测试结果表明,该系统具有较高的吞吐量和数据转发能力。To improve the throughput and data forwarding performance of application switching system,an application switching system based on the three-wire interconnection of computing chip and switching chip was proposed.Through the way of direct connection between the computing chip and the switching chip,the multiple conversion of data signals was avoided,and the network switching delay was reduced.Through the way of unloading the calculation of the two-layer and three-layer networks,the bandwidth utilization of the application switching of the four and seven layers was increased.Through the way of data direct accessing across the kernel,the data forwarding processing ability was improved.The load stress test results show that the proposed system has high throughput and data forwarding ability.
