一种基于FC总线的三层组播通信功能设计和实现

Design and Implementation of a Three tier Multicast Communication Function Based on FC Bus

一般情况下,FC总线数据传输功能需要上层软件、底层硬件和操作系统一起配合才能进行,而数据的实时性传输、低误码率传输以及高可靠性传输对软件和硬件的要求都比较高,并且需要软件和硬件进行高效率配合。当整个FC总线网络设备关系极其复杂,但又对FC总线数据通信要求比较高时,就需要用到FC总线的组播通信功能。对此提出一种基于FC总线的三层组播通信功能设计和实现方法,介绍了现有的二层组播通信模式的概念以及弊端,提出了三层组播通信模式的概念以及其相对于二层组播模式的优势,在满足航电系统基础的使用要求之上,进一步提升了FC总线设备应用的灵活性,将应用和硬件设备解绑,提高了FC总线通信的稳定性和可靠性。

In general,the FC bus data transmission function requires the cooperation of upper software,underlying hardware and operating system,while real time data transmission,low bit error rate transmission and high reliabilite transmission require high software and hardware,and requires high efficiency cooperation between software and hardware.When the relationship between the entire FC bus network equipment is extremely complex,but the data communication requirements of the FC bus are relatively high,the multicast communication function of the FC bus is needed.In this regard,this paper proposes a three tier multicast communication function design and implementation method based on FC bus,introduces the concept and disadvantages of the existing two tier multicast communication mode,and puts forward the concept of three tier multicast communication mode and its advantages over the two tier multicast mode to meet the basic requirements of avionautical power systems.In this regard,it further improves the flexibility of FC bus equipment application,unbinds applications and hardware equipment,and improves the stability and reliability of FC bus communication.
