Since the receiving device has not yet performed a forced cut, the receiving device should receive the CR instruction of the sending device as 0.

具体实施方式

需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
随着通讯设备的接口速度从10M带宽提高到100M、1G、10G，每隔几年业务速度就翻几倍，以适应网路上业务流量的需求。目前通讯设备商用光模块的速度已经达到100G，并开始大量商用。在光模块速度开始超越100G时，光模块研发技术上遇到的困难越来越大，光模块的生产成本急剧增加。在从100G向400G发展中，虽然已经研发出400G的光模块，但400G的光模块的价格昂贵，超过了4个100G光模块的价格，导致400G光模块缺少商用的经济价值。在不增加成本的情况下，为了解决400G业务的传递需求，能够在100G光模块上传递400G业务，国际标准组织定义了灵活以太(FlexE)协议。
根据FlexE协议标准，FlexE下记录了两种不同的通道信息，也叫日历(Calendar)信息，这两种通信息对应的通道分别定义为第一通道(Calendar A)和第二通道(Calendar B)，即通道A和通道B。FlexE的带宽在Calendar A和Calendar B中可以是相同的，也可以是不相同的，并通过开销帧进行本地与远端互通以实现切换。比如，FlexE的带宽总共有200M，则Calendar A可以分配100M、Calendar B分配100M，也可以是Calendar A分配50M、Calendar B分配150M。FlexE的带宽在通信过程中，一端定义为发送设备时，另一端则定义为接收设备。当发送设备和接收设备当前正在使用Calendar A互通时，则Calendar A为主用通道，Calendar B为备用通道；反之，当发送设备和接收设备当前正在使用Calendar B互通时，则Calendar B为主用通道，Calendar A为备用通道。
目前，FlexE的发送设备和接收设备在互通过程中，当需要进行第一通道和第二通道的切换时，例如，当前通道需要扩容或者当前通道故障等情况，发送设备通过开销帧向接收设备发送一个通道切换指令CR，接收设备在接收到该通道切换指令CR后，向发送设备返回一个应答指令CA，发送设备在接收到该应答指令CA后，将当前互通的通道从主用通道切换到备用通道。这种通道切换过程，依赖于稳定的FlexE，而实际工作过程中，存在许多影响通信稳定的因素，从而导致FlexE在通信过程中不定时的会出现丢包现象。当FlexE通信过程无法及时传输通道切换指令或应答指令时，通过双方应答来进行通道切换的方式，无法及时完成通道切换，从而增加通信过程的丢包率。
基于此，本申请实施例提供了灵活以太的时隙资源配置方法、终端及存储介质，通过在发送设备和接收设备配置通道切换模式，当通道切换模式为强切模式时，根据发送设备向接收设备发送通道切换指令的应答时长来判断是否执行强切模式，当应答时长大于开销帧协商周期时，发送设备执行强切模式，以将通道从第一通道切换到第二通道，同时接收设备在确定发送设备的当前时隙与自己的时隙不相同时，接收设备也从第一通道切换到第二通道，从而在FlexE不稳定的情况下，及时完成通道切换。
在本申请实施例提供的灵活以太的时隙资源配置方法中，灵活以太的转发通道FlexE Client包括第一通道和第二通道。在灵活以太的发送设备和接收设备需要进行通信时，灵活以太的转发通道FlexE Client根据带宽需求量向灵活以太的时隙资源池FlexE Group申请时隙，当时隙资源池FlexE Group内的可用时隙满足转发通道FlexE Client申请的时隙时，则转发通道FlexE Client对时隙资源池FlexE Group进行时隙绑定；当时隙资源池FlexE Group内的可用时隙不满足带宽需求量，将当前转发通道FlexE Client的时隙请求进行缓存，等待时隙资源池FlexE Group内的可用时隙满足转发通道FlexE Client申请的时隙。比如，如图1所示，时隙资源池FlexE Group包含一定量的时隙资源，每个时隙资源池FlexE Group内的时隙资源 可以分配给多个转发通道FlexE Client，每个转发通道FlexE Client所占用的时隙大小可以相同，也可以不相同，从图1可知，转发通道FlexE Client1占用两格的时隙资源、转发通道FlexE Client2占用两格半的时隙资源、转发通道FlexE Client3和转发通道FlexE Client4均占用一格的时隙资源。
在一些实施例中，在一个时隙资源池FlexE Group中，当多个转发通道FlexE Client中的一个FlexE Client向时隙资源池FlexE Group申请时隙或者释放时隙，均会引起该时隙资源池FlexE Group中所有时隙的变化。因此，不管是转发通道FlexE Client向时隙资源池FlexE Group申请时隙，还是释放时隙，转发通道FlexE Client绑定的所有转发通道FlexE Client均需要进行调整，从而也就可能引起每个转发通道FlexE Client下的第一通道和第二通道的切换。
在一些实施例中，在一个时隙资源池FlexE Group中，当转发通道FlexE Client绑定的时隙从可用状态变更为不可用状态，则将转发通道FlexE Client绑定的时隙从转发通道FlexE Client中删除，并触发通道切换模式。例如，转发通道FlexE Client中Calendar A的时隙由于受到外界因素的影响导致不可用时，则Calendar A无法进行数据传输，此时，转发通道FlexE Client从Calendar A切换到Calendar B，从而将Calendar A占用的时隙释放出来，以给其他转发通道FlexE Client使用，提高时隙资源的有效利用率。
在一些实施例中，当灵活以太中以Calendar A作为转发通道FlexE Client1的主用通道进行通信时，则Calendar B作为转发通道FlexE Client1的备用通道。在通信过程中，若Calendar A的时隙大小无法满足通信两端的通信需求，则需要对Calendar A进行扩容，或者对Calendar A进行切换。若对Calendar A直接进行扩容，则在扩容准备过程中，会使当前通信延时或者通信内容丢失。因此，将Calendar A直接切换到更大时隙的通道上，能够有效减少通信延时。可以理解的是，当确定Calendar A的当前时隙无法满足当前通信需求时，通过对转发通道FlexE Client的Calendar B进行扩容，同时Calendar A继续执行通信过程。在Calendar B绑定到更大时隙后，发送设备向接收设备发送一个通道切换指令CR，接收设备在接收到该通道切换指令CR后，向发送设备返回一个应答指令CA，在发送设备接收到该应答指令CA后，发送设备和接收设备同步将转发通道FlexE Client从Calendar A切换到Calendar B，即将Calendar B变成主用通道，将Calendar A变成备用通道，从而有效减少通信时延，降低丢包率。在这个过程中，通道切换指令CR是通过开销帧发送到接收设备，开销帧是在一个很小带宽的开销通道上进行传输的，该开销通道的传输过程，不受第一通道和第二通道的影响。例如，转发通道FlexE Client总的带宽大小为200M，则可以分配2M给开销通道，剩余的198M可以均分或者不均分的配置给第一通道和第二通道。
在Calendar A和Calendar B的切换过程中，为了提高通信数据的传输效率和准确率，降 低通信不稳定导致通道切换指令或者应答指令传输不及时带来的影响，可以通过在通信之前配置通道两端的通道切换模式，例如标准协商模式或强切模式，在实际工作过程中，通道切换模式可以根据当前通道的稳定性进行选择。
参照图2，通道时隙资源配置方法的强切模式包括以下步骤：
S110、当发送设备向接收设备通过开销帧发送通道切换指令，确定通道切换指令的应答时长。
可以理解的是，应答时长可以根据发送设备向接收设备发送通道切换指令的发送时间点和当前时间点进行计算确定。其中，当前时间点为未接收到接收设备返回应答指令的时间。例如，发送时间点为1点50分50秒，当前时间点为1点51分05秒，则应答时长为15秒。可以理解的是，应答时长也可以根据发送设备向接收设备发送通道切换指令的发送时间戳和当前时间戳进行计算确定。
S120、当应答时长大于开销帧协商周期，接收设备扫描发送设备发送的开销帧，并获取开销帧上对应发送设备的当前时隙，然后发送设备从第一通道切换到第二通道。
可以理解的是，开销帧协商周期是预先设置的一个时长，可以根据每个通道的正常握手时间来设置。例如，正常握手过程中，发送设备从发送通道切换指令CR的时间点到接收到该通道切换指令CR的应答指令CA的时间点为5秒，则开销帧协商周期可以设置为5秒。当应答时长大于5秒，则默认当前开销通道无法正常传输指令。此时，接收设备定时扫描开销通道上的开销帧，以根据开销帧上携带的时隙进行切换。其中，开销帧上携带的时隙与通道相关。例如，当前工作的通道为Calendar A，则发送设备发送的开销帧上的CR指令为0，接收设备接收到的开销帧上的CR指令也为0。若发送设备想要从Calendar A切换到Calendar B，则发送设备向接收设备发送的开销帧上的CR指令会变为1。也就是说，在通道切换过程中，开销帧上的CR指令是不相同的，因此，可根据该特征来获取开销帧上对应发送设备的当前时隙。在获取到发送设备的当前时隙后，发送设备对应的发送端从第一通道Calendar A强制切换到第二通道Calendar B上。
S130、当该当前时隙与接收设备的时隙不相同，接收设备从第一通道切换到第二通道。
可以理解的是，由于发送设备是执行强切过程，而发送设备在即将执行通道切换时，向接收设备发送的CR指令会发生变化。例如，发送设备在通道切换前，向接收设备发送的CR指令为0；发送设备在即将进行通道切换时，向接收设备发送的CR指令为1。而接收设备由于还没有进行强切，因此，接收设备接收该发送设备的CR指令应当为0，当接收到该发送设备的CR指令变成1，接收设备则可以确定发送设备执行了强切过程，因此，接收设备也执行强切过程，以从Calendar A切换到Calendar B，与发送设备保持在同一个时隙上，从而提高 数据传输的准确度。在这个过程中，发送设备向接收设备发送了变换后的通道切换指令CR后，再执行通道切换过程，以缩短发送设备和接收设备两端执行强切时的时间差，从而提高数据传输准确率。
在一些实施例中，在通道进行通信过程中，也会存在稳定的通信环境，因此，在环境稳定的情况下，可在通信两端配置标准协商模式作为通道切换模式。如图3所示，标准协商模式包括以下步骤：
S210、发送设备向接收设备发送通道切换指令，并等待接收该接收设备根据通道切换指令返回的应答指令。
S220、当发送设备接收到应答指令，发送设备和接收设备从第一通道切换到第二通道。
可以理解的是，在标准协商模式中，当通道需要切换时，发送设备通过改变开销帧上通道切换指令CR的值，将CR从0变成1。接收设备在接收到切换指令CR为1时，可确定发送设备想进行通道切换，因此，向发送设备返回一个应答指令CA，该应答指令CA也从0变成1，表示同意进行通道切换。发送设备在接收到应答指令CA为1时，发送一个控制指令C，控制指令C也从0变成1，以控制接收设备同步进行时隙切换，即从Calendar A切换到Calendar B。在完成通道切换后，开销帧上的CR、CA和C均恢复为0，以为下次通道切换做准备。
在一些实施例中，当通道切换模式配置为标准协商模式，如图4所示，标准协商模式下还包括以下步骤：
S230、当应答时长大于开销帧协商周期，恢复发送设备的通道切换指令。
可以理解的是，应答时长可以根据发送设备向接收设备发送通道切换指令的发送时间点和当前时间点进行计算确定。其中，当前时间点为未接收到接收设备返回应答指令的时间。在灵活以太的通信过程中，涉及两端的数据交互，当一端请求切换通道，另一端不同意切换通道时，在标准协商模式下，维持原来的通道，能有效提高数据传输的准确率。因此，在本实施例中，当发送设备向接收设备发送通道切换指令后，接收设备可以不返回应答指令。例如，发送设备向接收设备发送CR为1的通道切换指令，接收设备若不返回应答指令，则发送设备在一个开销帧协商周期后，若未接收到应答指令CA，则恢复通道切换指令CR的值，即将CR从1变回0，以提高下次通道切换过程的准确度。
在一些实施例中，当灵活以太的时隙资源池FlexE Group两端的物理端口的状态设置为一种状态时，即仅仅设置为物理状态时，当FlexE Group两端的设备连接时，时隙资源池FlexE Group是随机分配时隙给当前设备之间的通道。但是，此时两个设备的端口是处于UP状态，例如，两个设备通过网线连接，则两个设备此时处于UP状态。在这种UP状态下对用户端来说，用户是默认两个设备的端口是处于正常连接状态。若此时时隙资源池FlexE Group分配 给该设备通道的时隙是不可用的时隙，则即使两个设备的端口是处于UP状态，两个处于UP状态的设备也无法进行正常的通信。基于此，本实施例通过将时隙资源池FlexE Group两端的物理端口的状态设置为物理状态和时隙可用状态。其中，物理状态为开销通道状态，即用于进行数据传输；时隙可用状态为用于给物理状态配置可用时隙的状态，即在两个设备的端口处于UP状态时，从时隙资源池FlexE Group中选取可用的时隙分配给该设备通道，从而使得用户只需关注设备的状态，而无需关注通道的时隙状态，据此判断出设备是否能够正常通信，简化用户配置过程，提升用户网络规划量。
在一些实施例中，当时隙资源池FlexE Group的物理端口从不可用状态变更为可用状态，触发绑定时隙资源池FlexE Group的转发通道FlexE Client进行时隙补充，并触发通道切换模式。可用理解的是，在物理端口从不可用状态变更为可用状态时，可以确定当前物理端口的时隙可能不足，因此，通过时隙资源池FlexE Group对该物理端口进行时隙补充。在进行时隙补充时，若时隙资源池FlexE Group内的时隙不足，则将该补充过程放入缓存，以等待时隙资源池FlexE Group内的时隙足够补充时，再执行该时隙补充过程。
在一些实施例中，在转发通道FlexE Client两端的设备发生变化时，例如卡拔插、归属板拔插等，均会引起转发通道FlexE Client上对应通道的时隙删除。当对应通道发生时隙删除后，则将该转发通道FlexE Client切换到第二通道上，利用第二通道的时隙，完成接下来的数据传输过程。
在一些实施例中，在灵活以太的应用过程中，包括以下步骤：
步骤一、FlexE Client根据带宽需求量向FlexE Group申请与释放时隙。如图1所示，多个FlexE Client均可以根据自身的带宽需求量向时隙资源池FlexE Group申请申请时隙；或在自身不需要时隙时，向时隙资源池FlexE Group释放时隙，以使其他FlexE Client能够利用该释放的时隙。在申请时隙时，若时隙资源池FlexE Group内的时隙不足，则等待时隙资源池FlexE Group内可用时隙增加后，再进行FlexE Client时隙的补充。
步骤二、在时隙资源池FlexE Group对FlexE Client完成时隙分配后，FlexE Client对时隙资源池FlexE Group进行时隙绑定，从而在FlexE Client绑定期间，只有FlexE Client能够利用该时隙。
步骤三、在FlexE Client的时隙正常工作过程中，判断实时FlexE Client是否需要进行Calendar切换，若需要，则检查FlexE Client绑定的FlexE Group是否存在未接收到CA应答的CR动作，若存在，则将当前FlexE Client的更新操作放至缓存中，待未接收到CA应答的CR动作对应的FlexE Group接收到CA应答后，完成上一次的FlexE Group的Calendar切换，然后进行其他所有待切换的FlexE Client的Calendar对应的通道切换指令CR请求。若FlexE  Client绑定的FlexE Group不存在未接收到CA应答的CR动作，则更新该FlexE Client的备用Calendar，并发送该FlexE Group的时隙切换CR请求。在Calendar A和Calendar B之间进行切换的过程中，通过开销通道内嵌的请求-确认机制(Request-Acknowledge机制)实现。在开销通道内传输的开销帧中，包括以下三个指令：日历切换请求、日历切换应答和生效日历，即通道切换指令CR、应答指令CA和控制指令C。可用理解的时，在生效日历中，Calendar A由编码0表示，Calendar B由编码1表示。
步骤四、如图5所示，在接收到接收设备CA应答后，首先更新FlexE Client对应的硬件的Calendar控制，当前备用Calendar变更为主用Calendar，当前主用Calendar变更为备用Calendar，使主用时隙更新为备用时隙，并更新C比特值为当前Calendar控制值。当接收到接收设备CA应答超时，则进行发送设备的CR比特值恢复，即还是使用当前主用Calendar。
步骤五、对于FlexE Client的接收设备方向，定时扫描物理端口(PHY)的开销帧，在获取到发送设备当前发送方向的当前时隙后，更新FlexE Client的接收设备的主用Calendar时隙值，即将FlexE Client的接收设备的时隙更新为发送设备的当前时隙。如图6所示，在Calendar A和Calendar B之间的切换过程中，Calendar A和Calendar B在动态过程中切换，即经过一定的动态切换周期后，FlexE Client上的主用Calendar就变成了备用Calendar，而备用Calendar则变成主用Calendar。
步骤六、在FlexE Group绑定的物理端口的时隙从可用状态变更为不可用状态，或者物理端口发生子卡拔插、归属板拔插等现象时，将引起该物理端口的FlexE Client时隙删除，并发起步骤三的Calendar切换动作；若FlexE Group绑定的物理端口状态发生从不可用状态变更为可用状态时，则会触发所绑定的FlexE Group下的FlexE Client进行时隙分配，以进行带宽不足的FlexE Client时隙补充，同时发起步骤三的切换动作。其中，物理端口状态定义实现包括但不限于以下方面：第一、发送设备为FlexE端口，接收设备为以太端口，例如，发送设备的设备为UP状态，但是接收不到开销帧，则为线路接收侧信号丢失警告(LOF警告)，即链路状态UP，但时隙为不可用状态；第二、发送设备配置为FlexE端口，接收设备配置为FlexE端口，例如，发送设备的设备为UP状态，能接收到开销帧，若接收设备物理端口错误警告(RPF警告)，则链路状态UP，但时隙为不可用状态。在本实施例中，发送设备和接收设备均为相对而言，即本端为发送设备，则对端为接收设备；本端为接收设备，则对端为发送设备。
在步骤一至步骤六的Calendar A和Calendar B的切换过程中，虽然能够完成无损切换，但是，切换的前提均是接收设备和发送设备能够完成正常握手过程。但是，网络链路如果出现震荡，则会导致发送设备和接收设备无法正常握手。
基于此，考虑网络通信不稳定的情况，对FlexE Group增加发送设备和接收设备的配置参数约束，即在发送设备和接收设备配置通道切换模式，其中，通道切换模式包括标准协商模式和强切模式。标准协商模式仅根据CR标记来变更开销帧，即接收设备根据CR标记通告FlexE Client进行时隙变更；强切模式是在标准协商模式下增加定时扫描开销帧，获取发送设备当前发送方向的时隙值，并根据发送设备发送的当前时隙值更新接收设备的主用Calendar时隙。
对于发送设备进行Calendar切换模式选择时，当选择标准协商模式，则如步骤三和步骤四所示，该模式在能正常握手的情况下，可实现无损切换；当选择强切模式，则在步骤四接收应答超时时，FlexE Client的发送设备进行强制切换，接收设备根据扫描到的开销帧进行强制切换，从而使得通信正常执行，提高通道切换过程的可靠性。
