Description

成员动态处理方法、系统、接收端、管理实体及存储介质 技术领域
本发明涉及数据通信领域，尤其涉及一种灵活以太网FlexE中的成员动态处理方法、系统、接收端、管理实体及存储介质。
背景技术
随着互联网的快速发展，传统标准以太网络传输不能够满足大速率业务传输的需求。以太灵活网(Flex Ethernet，简称为FLexE)是一种新的弹性以太网客户端接口，它是在介质访问控制子层(媒体接入控制(Media Access Control，简称为MAC)与实体编码子层(Physical Coding Sublayer，简称为PCS)之间的一种介质，用于对客户端业务的分配。FlexE中群组(Group)是一个重要的概念，它可绑定1到n个实体的以太端口物理层(PHY，Port Physical Layer)成员。Group中绑定的成员可承载相同业务，也可承载不同的业务，并且可根据网络传输的需要，添加或者删除成员以适应业务端口增加或减少的需求。
在Group组内多个成员中往往承载大于1个业务端口，这些业务根据分配的FlexE时隙，按照固定的位置放置在每个PHY成员上。FlexE中为标记这个固定的位置增加头开销字节(OverHead，OH)，Group内每个成员插入OH的时刻相同。OH后的每个固定的时隙对应的业务都是唯一并且固定的，在应用中，只要找到OH的位置，就能从时隙中恢复出业务，也就是可以将接收到的数据按照业务进行区分。实际应用中，MAC层的一个业务往往被分配到Group组内多个成员上，经过远距离的传输，到达接收端。接收端为恢复出业务与时隙的关系，需要找到group组内成员的OH的位置，从这个位置后可标记出数据与业务的关系。因实体的PHY传输时，受传输介质材料差异，距离，环境等因素影响，Group内成员到达接收端存在一个物理延迟(skew)。为恢复出相同OH位置，接收端需要对group内的PHY成员deskew(将数据放在缓存中，等待OH都到来时， 共同读取数据)，去掉不同PHY成员之间的延迟，确保OH同一时刻在同一位置。
网络传输的过程中，在需要增加传输业务，或者需要节约带宽减少传输业务时，需要增加或者删除PHY成员。在对PHY成员动态处理，如增加或删除成员时，需要对Group组内的PHY成员重新deksew，从而影响正常传输的业务，导致数据传输异常。
发明内容

具体实施方式
以下结合说明书附图及具体实施例对本发明技术方案做进一步的详细阐述。除非另有定义，本文所使用的所有的技术和科学术语与属于本发 明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
在以下的描述中，涉及到“一些实施例”的表述，其描述了所有可能实施例的子集，但是应当理解，“一些实施例”可以是所有可能实施例的相同子集或不同子集，并且可以在不冲突的情况下相互结合。
对本发明进行进一步详细说明之前，对本发明实施例中涉及的名词和术语进行说明，本发明实施例中涉及的名词和术语适用于如下的解释。
1)、灵活以太网FlexE，承载网实现业务隔离承载和网络分片的一种接口技术。其中，灵活以太网技术通过对以太网轻量级增强，在以太网介质访问控制子层L2(MAC)/以太端口物理层L1(PHY)之间的中间层增加灵活以太网管理实体(FlexE Shim)，Flex Shim基于时分复用分发机制，将多个客户端口(Client)的数据按照时隙方式调度并分发至多个不同的成员链路子通道。以100GE管道为例，通过FlexE Shim可以划分为20个5G速率的子通道，每个Client侧接口可指定使用某一个或多个成员链路子通道，实现业务隔离。
2)、头开销字节(overhead，OH)，净(负)荷是相对开销而言的。由于网络是分层结构，数据自上向下转换时，每层都会加上一定数量的OH，而原来的数据就被称为净荷(payload)。
对于增加OH的业务数据而言，每一个业务数据由头和数据组成，头即是开销，而后面的数据即是业务数据的净荷。
3)、群组(Group)，是指通过链路捆绑将多个封装相同的链路层协议的接口捆绑到一起，形成一条逻辑上的数据链路，也即群组。
相同群组内的成员链路可以包括如下作用：流量负载分担：出/入流量可以在多个成员接口之间分担；增加带宽：链路捆绑接口的带宽是各可用成员接口带宽的总和；提高连接可靠性：当某个成员接口出现故障时，流 量会自动切换到其他可用的成员接口上，从而提高整个捆绑链路的连接可靠性。
4)、成员，是指同一群组内包含的链路成员。
5)、校正延迟(deskew)，是指群组成员对数据进行传输过程中，受传输介质材料差异，距离，环境等因素影响，同一群组内成员达到接收端将存在一个物理延迟skew，为了去掉不同成员之间的延迟的方式则为校正延迟。
在网络传输的过程中，在需要增加传输业务，或者需要节约带宽减少传输业务时，需要增加或者删除群组内成员。请参阅图1，以灵活以太网FlexE为例，Flex Shim基于时分复用分发机制，将多个客户端口(Client)的数据按照时隙方式调度并分发至多个不同的成员。FlexE群组内捆绑多个成员Phy_member，如4个，通过所述多个Phy_member共同承载多个Flexe_Client接口业务数据，如10个，所述多个Phy_member均是满流量运行，因通讯网络传输需求，在本群组内，需要增加一个或者多个Flexe_Client，如增加新增客户端(New add client)，或者所述多个Flexe_Client中有一个或者多个端口流量增大，所述多个Phy_member均为满流量运行无多余带宽承载新增加的客户端业务的情况下，此时可以通过增加群组内成员，如增加新成员(New add phy)的方式。
请参阅图2，仍以FlexE为例，FlexE群组内捆绑多个Phy_member，如4个，所述多个Phy_member共同承载多个，如10个Client的数据。在网络传输过程中，所述Client的数据流量减小或者某些业务端口不再有数据流传输，需要删除一个Flexe_Client，如删除一业务端口(Delete original client)，总的流量减少，此时可以根据减少流量的大小去除群组内一个或者多个成员，如删除一个原有成员(Delete original phy)的方式，删除的成员可以被其它群组新增后所调用。
在上述增加或删除成员时，接收端均需要对群组内成员重新deskew，从而可能会影响到正常传输的业务，基于此，有必要提供一种群组内成员 的动态处理方法，所述动态处理包括动态增加、动态删除，确保在数据业务不受影响的前提下，完成成员的动态增加或删除操作。
请参阅图3，为本申请实施例提供的一种灵活以太网FlexE中的成员动态处理方法，可应用于接收端，该方法包括如下步骤：
步骤101，根据待增加成员所属群组，获取所述待增加成员和所述群组内原成员分别对应的缓存数据的头开销字节OH的位置，确定所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系；
这里，待增加成员是指根据通讯网络传输需求，需要在群组内增加的新成员，如图1中所示的成员New add phy。需要说明的是，在群组内增加的新成员可以是完全新增的链路成员、也可以是群组内之前处于失效状态的链路成员通过恢复回复到群组内的链路成员。在FlexE中动态新增成员时，可以首先通过Flex Shim配置FlexE时隙表，配置该待增加成员所属的群组Group。发送端根据所述Flex Shim配置的FlexE时隙表，将所述Group对应承载的Client接口的业务根据所分配的FlexE时隙，按照固定的位置放置在所述Group内的成员上，并通过插入头开销字节OH对这个位置进行标记。通过Flex Shim配置该待增加成员所属Group，发送端根据分配到所述待增加成员的业务的位置按照设置间隔插入所述OH。按照设置间隔是指在数据中周期性插入OH，如，根据相应协议每隔1023*20*8个数据块插入一个OH标识。
所述接收端根据待增加成员所属群组，当所属Group内原成员的OH到来时，将对应的OH以及后续数据同样写入缓存中；相应的，等待所属Group内所述待增加成员的OH到来时，将对应的OH以及后续数据写入缓存中。所述接收端获取所述待增加成员和所述群组内原成员分别对应的缓存数据的OH的位置，确定所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系，所述接收端从缓存中按照指定的读取速率分别读取所述待增加成员和所述群组内原成员分别对应的缓存数据，根据所述对应的缓存数据的OH的位置，确定所述待增加成员的OH位置与所述原 成员的OH位置的相对位置关系。
步骤103，确定所述相对位置关系不满足设置条件时，对所述待增加成员或所述原成员的读取速率进行调整。
在发送端，同一Group内每个成员插入OH的时刻相同，在成员到达接收端不存在路径延迟skew的情况下，待增加成员和原成员的OH在同一时刻应在相同位置。这里，设置条件是指OH的位置相同、或者是指OH的相对位置之间的差值小于预设值。接收端通过确定同一Group内所述待增加成员的OH位置与原成员的OH位置的相对位置关系，当所述相对位置关系不满足设置条件时，则表示所述待增加成员和所述原成员的数据skew不一致，从而对所述待增加成员或所述原成员从缓存中读取数据的读取速率进行调整，以相应调整所述待增加成员或所述原成员的skew。通过对所述待增加成员或所述原成员从缓存中读取数据的读取速率进行调整，实现了数据边传输边等待的方式，确保了不影响原业务的正常传输。
所述FlexE中的成员动态处理方法还包括：确定所述相对位置关系满足所述设置条件时，则所述待增加成员和所述原成员实现数据同步。
接收端通过确定同一Group内所述待增加成员的OH位置与原成员的OH位置的相对位置关系，当所述相对位置关系满足设置条件时，则表示所述待增加成员和所述原成员的数据skew一致或基本一致，可保证在下一个OH到来时，所述待增加成员和原成员的OH同时出现，所述待增加成员和所述原成员实现数据同步，所述待增加成员的动态增加入Group成功。
在一些实施例中，所述步骤103，确定所述相对位置关系不满足设置条件时，对所述待增加成员或所述原成员的读取速率进行调整，包括：
确定所述相对位置关系不满足设置条件时，对所述待增加成员或所述原成员的读取速率进行调整，并重新确定所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系；
当所述相对位置关系仍然不满足设置条件时，返回所述对所述待增加成员或所述原成员的读取速率进行调整的步骤，直至所述相对位置关系满足所述设置条件。
这里，接收端根据同一Group内所述待增加成员的OH位置与原成员的OH位置的相对位置关系，确定所述相对位置关系不满足设置条件，对所述待增加成员或所述原成员的读取速率进行调整的过程中，可以是一次调整或者多次调整，以对所述待增加成员的读取速率进行调整为例，可以将待增加成员的读取速率调整为当前速率的二分之一，调整后再重新确定所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系是否满足设置条件，当所述相对位置关系仍然不满足设置条件时，则可以再次对所述待增加成员的读取速率进行调整，再次将待增加成员的读取速率调整为当前速率的二分之一，并于调整后再次重新确定所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系是否满足设置条件；如此往复进行，直至所述相对位置关系满足所述设置条件。
需要说明的是，上述对所述待增加成员或原成员的读取速率进行调整的过程中，可以是根据设置的调整策略进行，所述调整策略可以是将当前读取速率按照一定比例系数相乘的方式来确定；或者，也可以是当前读取速率按照一定幅度递减的方式来确定；或者，还可以是将当前读取速率按照逐渐递增或递减的比例系数相乘的方式来确定等。
本申请上述实施例中，通过对所述待增加成员或所述原成员的读取速率逐步进行调整，可以使得所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系逐步趋向满足设置条件，确保原业务不受影响继续传输的前提下实现待增加成员和原成员的数据同步。
在一些实施例中，所述对所述待增加成员或所述原成员的读取速率进行调整，包括：
确定所述待增加成员的OH位置相对所述原成员的OH位置超前时， 降低所述待增加成员的读取速率；或者，确定所述待增加成员的OH位置相对所述原成员的OH位置落后时，降低所述原成员的读取速率。
这里，接收端确定所述待增加成员的OH位置相对于所述原成员的OH位置超前时，说明所述待增加成员的OH提前出现，也即所述待增加成员的数据skew相对于原成员的数据skew小，所述待增加成员应多缓存数据以等待原成员数据，从而原成员的读取速率不变，并降低所述新增成员的读取速率，以减小所述待增加成员的OH位置与原成员的OH位置之间的差值。相应的，接收端确定所述待增加成员的OH位置相对于所述原成员的OH位置落后时，说明所述待增加成员的OH落后出现，也即所述待增加成员的数据skew相对于原成员的数据skew大，需要增加原成员的数据skew，从而所述新增成员的读取速率不变，并降低原成员的读取速率，以减小所述待增加成员的OH位置与原成员的OH位置之间的差值。
其中，所述降低待增加成员的读取速率包括：将所述待增加成员的读取速率降低为当前速率的二分之一；所述降低原成员的读取速率包括：将所述原成员的读取速率降低为当前速率的二分之一。
需要说明的是，所述降低所述待增加成员的读取速率以及所述降低所述原成员的读取速率，还可以是根据设置的调整策略逐步降低，如，所述调整策略可以是每次将读取速率降低为当前速率的不限于以上所述的二分之一的其它比例；或者，可以是每次将读取速率降低一定幅度；或者，还可以是将读取速率降低为当前速率与逐渐递增或递减的比例系数的乘积等。通过根据设置的调整策略逐步降低，可以使得所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系逐步趋向满足设置条件，确保原业务不受影响继续传输的前提下实现待增加成员和原成员的数据同步。
在一些实施例中，所述获取所述待增加成员和所述群组内原成员分别对应的缓存数据的头开销字节OH的位置，确定所述待增加成员的OH位 置与所述原成员的OH位置的相对位置关系，包括：
按照设置的第一读取速率读取所述待增加成员对应的缓存数据，并对读出数据进行第一计数，当读取到数据的OH的位置时，所述第一计数清零；
根据设置的第二读取速率读取所述群组内原成员对应的缓存数据，并对读出数据进行第二计数，当读取到数据的OH的位置时，所述第二计数清零；
根据所述第一计数与所述第二计数的大小，确定所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系。
这里，接收端设置分别与待增加成员和原成员对应的第一计数器和第二计数器，由于OH在相应数据中是周期性出现的，通过第一计数器和第二计数器分别计算同一周期内待增加成员和原成员对应的缓存数据在OH的位置之后的读出数据的计数，对比两个计数的差值可以确定所述待增加成员和原成员的OH的位置之间的相对位置关系，如此，可以根据不同读取速率下对应获取到的所述待增加成员和原成员的缓存数据在同一周期内的OH的位置，从而确定在不同读取速率下所述待增加成员和原成员的OH的位置的相对位置关系的差值变化。
其中，接收端在确定待增加成员的OH到来时写入缓存中，在独享存储不为空时，按照设置的第一读取速率读取所述待增加成员对应的缓存数据，并对读出数据进行第一计数，待读取到OH时清空计数。从缓存中读取Group组内原成员对应的缓存数据，可读出数据的条件可以为所有原成员的OH都已经写入缓存中，读出的第一组数据须为OH标识。相应的，接收端按照设置的第二读取速率读取所属Group内原成员对应的缓存数据，一次读取包括从缓存中拉取每个原成员的一个数据，若其中一个原成员的数据为空，则放弃读，并等待数据非空时读出，每次读出一组数据第二计数增加1，待读取到OH时清空计数。接收端通过对比所述第一计数和所述第二计数的大小，可以确定所述待增加成员的OH位置与所述原成 员的OH位置的相对位置关系。
本申请上述实施例中，通过根据对待增加成员和原成员对应的缓存数据在每一周期内OH的位置之后的数据进行计数，利用数据中OH周期性出现的规律，当读取到数据的OH的位置时则相应计数清零，从而可以在对所述待增加成员或所述原成员的读取速率进行调整的过程中，能够获取对应在不同读取速率下，所述待增加成员和原成员对应的缓存数据在每一周期内OH的位置之后的数据的对应计数值，以确定所述待增加成员的OH位置与所述原成员的OH位置之间的相对位置关系。
在一些实施例中，所述根据所述第一计数与所述第二计数的大小，确定所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系，包括：
当所述第一计数为零，所述第二计数大于阈值时，则确定所述待增加成员的OH的位置相对所述原成员超前；
当所述第一计数为零，所述第二计数小于或者等于所述阈值时，则确定所述待增加成员的OH的位置相对所述原成员落后。
这里，所述阈值根据数据中OH标识的设置间隔确定。以每隔1023*20*8个数据块插入一个OH标识为例，所述阈值可以为1023*20*8/2。请参阅图4，若待增加成员对应的读出数据为OH且计数为零，原成员对应读出数据的计数值大于阈值，如可以在(1023*20*8～1023*20*8/2)范围内时，说明待增加成员的OH的位置相对所述原成员超前；请参阅图5，若待增加成员对应的读出数据为OH且计数为零，原成员对应读出数据的计数值小于阈值，如可以在[1023*20*8、2～0)范围内时，说明待增加成员的OH的位置相对所述原成员落后。根据所述待增加成员的OH位置与所述原成员的OH位置的相对位置关系，相应逐步调整所述待增加成员和所述原成员的读取效率，以减小所述待增加成员和所述原成员之间的数据skew的差值，直至所述待增加成员和所述原成员实现数据同步。
请参阅图6，为本申请实施例提供的一种灵活以太网FlexE中的成员动态处理方法，可应用于灵活以太网管理实体FlexE SHIM，该方法包括如下步骤：
步骤201，配置FlexE时隙表，根据待删除成员的头开销字节OH的位置，将所述待删除成员的业务配置为空业务；
这里，Group群组内各成员承载的业务是由时隙表配置确定的，时隙表是从OH位置开始分配每个时隙对应的业务数据。所述FlexE SHIM配置FlexE时隙表，根据待删除成员的头开销字节OH的位置，将所述待删除成员的业务配置为空业务，可以是所述FlexE SHIM将需要删除的待删除成员的业务配置为空业务，不承载有效业务，仅保留OH标记。
步骤203，将所述待删除成员所属群组的缓存数据的读取条件中将所述待删除成员剔除。
这里，所述FlexE SHIM将所述待删除成员剔除，可以是所述FlexE SHIM根据时隙表的配置，确定所述待删除成员具体对应为哪个成员，并将接收端从缓存中读取数据的读取条件配置为将该对应的成员剔除，从而不再判断该待删除成员的缓存数据的状态，由于该待删除成员上不再承载有效业务，数据可直接丢弃，从而在不影响业务流的情况下，可以实现对该删除成员的动态删除操作。所述FlexE SHIM将所述待删除成员从Group内删除后，停止该待删除成员上的操作，并将其设置为未使用成员可供其它Group增加调用。
本申请上述实施例中，在删除成员时，所述FlexE SHIM配置FlexE时隙表，根据待删除成员的头开销字节OH的位置，将所述待删除成员的业务配置为空业务，将所述待删除成员所属群组的缓存数据的读取条件中将所述待删除成员剔除，如此，可以通过配置待删除成员不再承载有效业务的方式，因待删除成员上不再承载有效业务数据可直接丢弃，确保不影响业务流的情况下，完成成员的动态删除操作，从而更好的满足网络传输 需求。
在一些实施例中，所述FlexE中的成员动态处理方法，还包括：
配置待增加成员所属群组，所述配置用于指示发送端根据分配到所述待增加成员的业务的位置，按照设置间隔插入OH。
这里，FlexE中动态增加成员时，接收端确定待增加成员所属群组之前，还包括所述FlexE SHIM配置待增加成员所属群组，如所述FlexE SHIM通过命令配置告知Group有新的成员加入。通过所述FlexE SHIM配置待增加成员所属群组，发送端根据分配到所述待增加成员的业务的位置，按照设置间隔插入OH标识；接收端根据所述配置确定待增加成员所属群组，并对待增加成员对应的数据中找到OH标识锁定后，将所述OH及后续的数据写入缓存中，以能够通过获取所述待增加成员和所述群组内原成员分别对应的缓存数据执行后续的动态增加步骤。
为了能够对本申请实施例所提供的FlexE中的成员动态处理方法的实现流程能够进一步具体的了解，下面结合三个可选的具体实施例进行说明，请参阅图7，以动态处理为动态增加为例，其中，FlexE中Group内绑定4个PHY成员(也可大于也可小于4个成员，以4成员为例)，4个PHY成员共承载10个客户端口(也可大于10个客户端口或少于10个客户端口，以10个为例)。4个PHY成员均是满流量运行，因通讯网络传输需求，在本Group内，需要增加1个客户端口(也可增加多个客户端口)，或者，10个客户端口中有一个或者多个端口的流量增大，4个成员均为满流量运行，无多余带宽承载新增客户端业务，此时可通过动态增加成员的方式，所述FlexE中的成员动态处理方法包括如下步骤：
步骤S11，FlexE SHIM配置待增加成员所属群组；如，FlexE SHIM通过命令配置告知Group有待增加成员将加入；
步骤S12，发送端在待增加成员上按照每隔1023*20*8个数据块插入 一个OH标识的标准插入OH。
步骤S13，接收端检测待增加成员的OH，待检测到OH后将OH及后续数据存入缓存区内，并从缓存区内读出数据并对读出数据个数进行计数；且接收端检测原成员的OH，待检测到OH后将OH及后续数据存入缓存区内，并从缓存区内读出数据并对读出数据个数进行计数；
步骤S14，接收端根据从缓存区中读出待增加成员的数据计数、以及读出原成员的数据计数进行对比，确定所述待增加成员OH与原成员OH之间的相对位置关系；
若所述待增加成员OH相对于原成员OH落后，则执行步骤S15；若所述待增加成员OH相对于原成员OH超前，则执行步骤S16；若所述待增加成员OH与原成员OH的位置相同，则执行步骤S17；
步骤S15，降低所述原成员对应的数据读取速率，直至所述待增加成员OH与原成员OH的位置相同，执行步骤S17；
步骤S16，降低所述待增加成员对应的数据读取速率，直至所述待增加成员OH与原成员OH的位置相同，执行步骤S17；
步骤S17，接收端根据相同的数据读取速率从缓存区读取所述待增加成员和原成员对应的缓存数据；
步骤S18，FlexE SHIM对所述待增加成员上分配客户端口业务，承载增加的流量。
请参阅图8，以动态处理为动态增加为例，其中，FlexE中Group内绑定4个PHY成员(也可大于或小于4个成员，以4成员为例)，4个PHY成员共承载10个客户端口(也可大于10个客户端口或少于10个客户端口，以10个为例)。在网络传输过程中，某个PHY成员在传输途中由于受干扰源影响，稳定性较差，误码率较大，处于失效状态，但是可确保一段时间内干扰消失，失效状态可恢复正常。但受到干扰的影响，受影响的PHY成员的数据链路skew可能发生变化，与其他三个成员的OH的相对位置关系将发生变化，需要重新确定Group内OH的位置，在重新确定的 过程中，可通过动态增加成员的方式将要恢复的成员作为待增加成员增加到Group内，所述FlexE中的成员动态处理方法包括如下步骤：
步骤S21，接收端根据链路状态指示确定待恢复成员已恢复稳定，并确定所述待恢复成员所属群组；
步骤S22，接收端检测待恢复成员的OH，待检测到OH后将OH及后续数据存入缓存区内，并从缓存区内读出数据并对读出数据个数进行计数；且接收端检测原成员的OH，待检测到OH后将OH及后续数据存入缓存区内，并从缓存区内读出数据并对读出数据个数进行计数；
步骤S23，接收端根据从缓存区中读出待恢复成员的数据计数、以及读出原成员的数据计数进行对比，确定所述待恢复成员OH与原成员OH之间的相对位置关系；
若所述待恢复成员OH相对于原成员OH落后，则执行步骤S25；若所述待恢复成员OH相对于原成员OH超前，则执行步骤S26；若所述待恢复成员OH与原成员OH的位置相同，则执行步骤S27；
步骤S25，降低所述原成员对应的数据读取速率，直至所述待恢复成员OH与原成员OH的位置相同，执行步骤S27；
步骤S26，降低所述待恢复成员对应的数据读取速率，直至所述待恢复成员OH与原成员OH的位置相同，执行步骤S27；
步骤S27，接收端根据相同的数据读取速率从缓存区读取所述待恢复成员和原成员对应的缓存数据；
步骤S28，FlexE SHIM对所述待恢复成员上分配客户端口业务，承载失效之前的业务。
上述实施例中，所述待恢复成员即指动态增加成员操作过程中的待增加成员，实现在不影响Group内其它正常成员的情况下完成失效成员的恢复。
请参阅图9，以动态处理为动态删除为例，其中，FlexE中Group内 绑定4个PHY成员(也可大于或小于4个成员，以4成员为例)，4个PHY成员共承载10个客户端口(也可大于10个客户端口或少于10个客户端口，以10个为例)。在网络传输过程中，10个客户端口的流量减小或者某些客户端口不再有数据流传输，总的流量减少，此时可以根据减少流量的大小适量去除Group内成员，去除的成员可被其他Group利用，在去除的过程中相当于在Group内删除一个成员，需要重新确定Group内OH的位置，在重新确定的过程中，可通过动态删除成员的方式，所述FlexE中的成员动态处理方法包括如下步骤：
步骤S31，FlexE SHIM将要删除的成员上的业务配置为空业务；其中，Group内成员承载的业务是由时隙表配置，时隙表是从OH位置开始分配每个时隙对应的业务数据。将需要删除的成员的业务配置为空业务，不承载有效业务，只保留OH标记。
步骤S32，FlexE SHIM将从缓存中读取数据的读取条件中将该要删除的成员剔除；其中，从缓存中读数据的读取条件中将该要删除的成员剔除，不判断此成员的缓存状态，因删除的成员上不再承载业务，数据可直接丢弃，不影响业务流，且不会影响其他的成员，最后完成PHY成员的无损删除。
本申请上述实施例提供的FlexE中的成员动态处理方法，在网络传输中增加或删除客户端口业务时，可不影响其他客户端口的正常工作的前提下，实现Group内成员的动态增加和删除操作，从而能够动态无损调整带宽的大小，提高网络传输的灵活性。
