基于FC-AE-ASM的IP业务传输方法的设计实现

随着FC-AE网络在高可靠性网络中的应用越来越广泛,在FC-AE网络上传输IP业务不仅拓宽了FC-AE网络的应用范围,而且能够实现FC-AE网络与以太网网络的融合.提出了基于FC-AE-ASM协议的IP业务传输方案,在支持FC-AE-ASM协议的HBA卡物理设备上,构建了一个虚拟网卡内核模块.本方案扩展了TCP/IP协议栈,在网络接入层下扩展了一个FC接口层,实现了FC-AE-ASM帧对以太网帧的封装和解封装.同时,利用FC网络底层流控机制,实现了IP业务在FC-AE网络上的高可靠性传输.通过实验组网测试可知,本方案在延时、带宽、抖动、丢包率等方面相对于商用千兆网卡都有较多的优势,在航空航天等应用场景具有重要的应用价值.

Design and Implementation of IP Service Transmission Method Based on FC-AE-ASM

With the increasing application of FC-AE network in high reliable network,the transmission of IP service over FC-AE network not only extends the application range of FC-AE network,but also can realize the convergence of FC-AE network and Ethernet network.An IP service transmission scheme based on FC-AE-ASM protocol was proposed,in which a virtual Ethernet card driver module was constructed on the FC-AE HBA card physical device.The scheme extends the TCP/IP protocol stack by adding a FC access layer under the network access layer.It implements encapsulation and de-encapsulation of Ethernet frames to/from FC-AE-ASM frames.At the same time,the flow control mechanism of FC network is used to ensure high reliable transmission of IP service.The experimental network test shows that this scheme has more advantages inerms of delay,bandwidth,jitter,and packet loss rate of IP services(UDP and TCP) than commercial Gigabit Ethernet card,and has important application value in many scenarios such as aerospace field.
