本申请要求于2021年4月22日提交的申请号为202110433557.4，发明名称为“FC交换机的控制方法、装置、FC交换机和存储介质”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域

背景技术
光纤通道(Fiber Channel，FC)是高速串行传输总线，由于其具备通道和网络的双重优势，具备高带宽、高可靠、抵抗电磁干扰等优点，能够提供非常稳定可靠的光纤连接，容易构建大型的数据传输和通信网络。FC-AE标准是一个应用到航空电子环境中的一组协议族，主要用于航空电子下各设备之间的数据通信，传输视频、指控、仪器仪表、传感器等数据，目前FC-AE网络得到了广泛的应用。
FC交换机作为FC网络中的核心设备，对整个FC网络的数据交换起着决定性的作用，因此对FC交换机交换数据进行监控与分析具有重大意义。但目前对交换机输入输出的数据进行监控的方法有：
1、采用光分路器进行监控。采用光分路器进行监控，实现方式简单且不需要交换机进行额外的设置，缺点在于只能够对一路端口进行监控，不能够对多路数据进行监控。
2、FC交换机增加额外的监控端口。采用增加监控端口的方式能够实现多路输入输出数据的监控，缺点是：该FC口只能作为监控端口，在不需要监控功能时该端口无作用；在监控超带宽时，会出现监控数据丢帧情况。

在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“连接”应做广义理解，例如，可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
下面结合图1-图2描述本申请的FC交换机的控制方法。
图1是本申请提供的FC交换机的控制方法的流程示意图。如图1所示，本申请提供的FC交换机的控制方法，包括：
S1：获取数据监控指令。
具体地，可以是用户终端向FC交换机发送数据监控指令，也可以是FC交换机根据系统策略，当满足预设FC交换机满足预设条件时，自动生成数据监控指令。示例性地，预设条件可以为当FC交换机超带宽。
S2：根据数据监控指令将FC交换机设置为数据监控模式。
S3：在数据监控模式下，将FC交换机的数据输出端口设置为监控端口，并通过轮询的方式从数据输入寄存器监控输入数据和从数据输出寄存器监控输出数据。其中，FC交换机的数据输出端口还用于在数据交换模式下进行数据交换。
在本申请的一个实施例中，步骤S3包括：
S3-1：从数据输入寄存器中获取输入数据，并将输入数据存入多个输入缓存。
图2是本申请一个示例中的数据监控的原理图。如图2所示，FC交换机设置有n个通道，n为大于1的整数。在监控模式下，数据输入寄存器可以对n个通道使能，从而监控n个通道的输入数据，然后将数据输入寄存器中的数据分别存入多个缓存中，本实施例采用多个先入先出缓存队列来缓存输入数据。
S3-2：从数据输出寄存器中获取输出数据，并将输出数据存入多个输出缓存。
请参考图2，在监控模式下，数据输出寄存器可以对n个通道使能，从而监控n个通道的输出数据，然后将数据输出寄存器中的数据分别存入多个缓存中，本实施例采用多个先入先出缓存队列来缓存输出数据。
需要说明的是，本实施例并不限定步骤S3-1和步骤S3-2的先后执行关系，即可以是先执行步骤S3-1，后执行步骤S3-2，也可以是先执行步骤S3-2，后执行步骤S3-1。
S3-3：获取轮询指令，根据轮询指令从多个输入缓存和多个输出缓存中轮询获取输入数据和输出数据。
在本申请的一个实施例中，步骤S3-3包括：根据轮询指令从多个输入缓存和多个输出缓存中确定第一目标缓存；检测第一目标缓存是否空数据；如果第一目标缓存空数据，则从多个输入缓存和多个输出缓存中确定第二目标缓存，从第二目标缓存中获取数据；从多个输入缓存和多个输出缓存中轮询获取数据，直至FC交换机退出数据监控模式。
具体地，本实施例采用分布式轮询算法，FC交换机根据分布式轮询算法依次循环调度各个输入缓存队列和输出缓存队列，如果遇到下一个空的缓存队列，会跳过该空的输出缓存队列，找到下一个非空的缓存队列。通过轮询方式，每个缓存队列公平的占用输出带宽，并且可以避免队列长时间得不到响应的情况。
在本申请的一个实施例中，FC交换机的控制方法还包括：获取数据交换指令；根据数据交换指令将FC交换机设置为数据交换模式；在数据 交换模式下，将FC交换机的数据输入端口和数据输出端口设置为数据交换端口。
具体地，当需要FC交换机进行数据交换时，可以给FC交换机发送数据交换指令，或者由FC交换机根据预设策略，在满足预设条件时自动生成数据交换指令，FC交换机根据数据交换指令进入数据交换模式，在数据交换模式下，将FC交换机的数据输入端口和数据输出端口设置为数据交换端口，从而进行数据交换。
在本申请的一个实施例中，FC交换机的控制方法还包括：从监控指令中提取数据筛选条件；根据数据筛选条件监控输入数据和所述输出数据。其中，数据筛选条件包括DID、SID、TYPE、R_CTRL、ASM_ID等等。
本申请提供的FC交换机的控制方法，采用FC交换端口逻辑与FC监控逻辑一体化设计，根据数据监控指令控制FC交换机进入数据监控模式，在数据监控模式下可以监控输入数据和输出数据，并可以对监控数据进行选择过滤，实现对FC交换机的数据监控，尤其是在超带宽时选择多路FC端口配置为监控端口；或者配置为普通交换端口，进行数据交换，增加了FC交换机的灵活性，提高了FC交换机端口数据的记录与分析能力，有利于问题的排查。
下面对本申请提供的FC交换机的控制装置进行描述，下文描述的FC交换机的控制装置与上文描述的FC交换机的控制方法可相互对应参照。
图3是本申请提供的FC交换机的控制装置的结构框图。如图3所示，本申请实施例的FC交换机的控制装置，包括：获取模块310和控制处理模块320。
其中，获取模块310用于获取数据监控指令。控制处理模块320用于根据数据监控指令将光纤通道FC交换机设置为数据监控模式。控制处理模块320还用于在数据监控模式下，将FC交换机的数据输出端口设置为监控端口，并通过轮询的方式从数据输入寄存器监控输入数据和从数据输出寄存器监控输出数据。其中，FC交换机的数据输出端口还用于在数据交换模式下进行数据交换。
在本申请的一个实施例中，控制处理模块320用于从监控指令中提取 数据筛选条件，并根据数据筛选条件监控输入数据和输出数据。
在本申请的一个实施例中，控制处理模块320用于从数据输入寄存器中获取输入数据，将输入数据存入多个输入缓存。控制处理模块320用于从数据输出寄存器中获取输出数据，并将输出数据存入多个输出缓存。控制处理模块320还用于获取轮询指令，根据轮询指令从多个输入缓存和多个输出缓存中轮询获取输入数据和输出数据。
在本申请的一个实施例中，控制处理模块320用于根据轮询指令从多个输入缓存和多个输出缓存中确定第一目标缓存，并检测第一目标缓存是否空数据；如果第一目标缓存空数据，则控制处理模块320从多个输入缓存和多个输出缓存中确定第二目标缓存，并从第二目标缓存中获取数据。控制处理模块320还用于从多个输入缓存和多个输出缓存中轮询获取数据，直至FC交换机退出数据监控模式。
在本申请的一个实施例中，多个数据输入缓存为多个先入先出缓存队列，多个数据输出缓存为多个先入先出缓存队列。
在本申请的一个实施例中，获取模块310还用于获取数据交换指令。控制处理模块320用于根据数据交换指令将FC交换机设置为数据交换模式。控制处理模块320用于在数据交换模式下，将FC交换机的数据输入端口和数据输出端口设置为数据交换端口。
