  • Standard Ethernet The 802.3 standard Ethernet (StdE) standard defined by the 802.3 working group of the Institute of Electrical and Electronics Engineers (IEEE) is widely cited in the industry. Standard Ethernet is greatly welcomed by manufacturers because of its simple principle, easy implementation and low price. However, with the development of technology, the difference in bandwidth particles is getting larger and larger, and the deviation between the ports of standard Ethernet and the actual application requirements is also increasing. A situation that is likely to occur is that the mainstream application requires bandwidth that does not belong to any existing Ethernet standard rate. For example, if a 50Gb/s service uses 100GE ports to carry the waste of resources, the 200Gb/s service is currently available. There are no corresponding Ethernet standard granules that can be carried.

背景技术
电气和电子工程师协会(Institute of Electrical and Electronics Engineers,IEEE)下属的802.3工作组所定义的802.3标准以太网(Standard Ethernet，StdE)的相关标准在业界被广泛引用。标准以太网以其原理简单、便于实现同时又价格低廉的优势受到厂商的极大欢迎。但是随着技术的发展，带宽颗粒差异越来越大，标准以太网的端口与实际应用需求的偏差也越来越大。很可能出现的一种情况是：主流的应用需求带宽不属于任何一种现有以太网标准速率，比如：50Gb/s的业务如果用100GE端口来承载存在资源浪费，而200Gb/s的业务目前还没有对应的以太网标准颗粒可以承载。
为了应对这一挑战，光互联网论坛(Optical Internet Forum,OIF)发布了灵活以太网(Flexible Ethernet,FlexE)，FlexE是一种支持多种以太网MAC层速率的通用技术。通过将多个100GE(Physical，PHYs)端口绑定，并将每个100GE端口在时域上以5G为颗粒划分为20个时隙，FlexE可支持以下功能：绑定，将多个以太网端口绑定为一个链路组以支持速率大于单个以太网端口的媒体访问控制(Medium Access Control，MAC)业务；子速率，通过为业务分配时隙支持速率小于链路组带宽或者小于单个以太网端口带宽的MAC业务；通道化，通过为业务分配时隙支持在链路组中同时传输多个MAC业务，例如在2x100GE链路组中支持同时传输一个150G和两个25G的MAC业务。
图1示出了现有技术中一种可能的通信***架构示意图，如图1所示，包括第一以太网设备1101和第二以太网设备1201，其中，第一以太网设备1101包括介质相关端口(Medium Dependent Interface，MDI)1102(图中为表述清楚写为MEDIUM1102)、物理层、媒介无关端口(Media Independent Interface，MII)1107、协调子层(Reconciliation Sublayer，RS)1108、媒体访问控制(Medium Access Control，MAC)层1109和上层(Upper layer)1110。其中，第一以太网设备1101的物理层可以包括物理媒介相关子层(Physical Medium Dependent，PMD)1104、物理媒介接入子层(Physical Medium Attachment，PMA)1105和物理编码子层(Physical Coding Sublayer，PCS)1106。上层(Upper layer)1110中可以包括网络协议(Internet Protocol，IP)层和传输控制协议(Transfer Control Protocol，TCP)层等。相应地，第二以太网设备1201包括介质相关端口(Medium Dependent Interface，MDI)1202(图中为表述清楚写为MEDIUM1202)、物理层、MII1207、RS1208、MAC层1209和上层(Upper layer)1210。其中，第二以太网设备1201的物理层可以包括PMD1204、PMA1205和PCS1206。上层(Upper layer)1210中可以包括IP层和TCP层等。
IEEE 802.3标准文档81.3.4章节定义40GE/100GE标准以太网协议中的本地故障信息(Local Fault，LF)和远端故障信息(Remote Fault)，其中，本地故障信息可以是指远端 RS和本地RS之间发生故障(英文可以为Faults detected between the remote RS and the local RS)，远端故障信息可以是当RS检测到LF时由RS生成RF(RF signal originated at RS when RS detects LF)。在协议中规定了本地RS与远端RS子层协商链路故障状态的机制，以及基于LF和RF的64b/66bit Block的发送和处理机制。
如图1所示，从第二以太网设备1201发送信息至第一以太网设备1101的链路发生故障，第一以太网设备1101中的物理层(比如PMD1104)检测到链路故障，PMD1104、PMA1105或PCS1106会生成LF并上送给上层功能单元，直至RS1108接收到LF。RS1108若检测到PCS1106通过MII1107端口上送的LF，则停止上层MAC数据流往PCS1106的下插，并向PCS1106持续下插RF，发往第二以太网设备1201。若第一以太网设备1101至第二以太网设备1201的发送链路完好，则RF可以抵达第二以太网设备1201。
第二以太网设备1201的RS1208检测到RF，停止上层MAC数据流往PCS1206的下插，并向PCS1206持续下插Idle控制块流(可以参见IEEE 802.3-2015Section 6中81.3.4章节)，Idle控制块流从第二以太网设备1201发往第一以太网设备1101，由于从第二以太网设备1201发往第一以太网设备1101的发送链路出现故障，因此Idle控制块流并不会抵达第一以太网设备1101。
通过上述示例可以看出，现有技术中可以在以太网设备中通过传输LF和RF实现故障协商，而以太网设备中的RS可以终结故障信息并停止MAC层数据流的发送。基于已经提出的灵活以太网协议，将标准以太网协议和灵活以太网协议联合组网势在必行，而目前针对标准以太网协议和灵活以太网协议联合组网还没有故障信息的传输方案。
综上所述，亟需一种通信方案用于实现标准以太网协议和灵活以太网协议联合组网中故障信息的传输。
发明内容
本申请实施例提供一种通信方法、设备及存储介质，用于实现标准以太网协议和灵活以太网协议联合组网中故障信息的传输。
第一方面，本申请实施例提供一种通信方法，该方法包括通过第一端口获得第一故障信息；其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息；第一故障信息为第一类型故障信息，第一类型故障信息包括本地故障信息和远端故障信息中的至少一项；根据第一故障信息，通过第二端口发送第二故障信息；其中，第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息；第二故障信息为第二类型故障信息，第二类型故障信息用于指示标准以太网协议对应的链路发生故障。
本申请实施例中通过第一端口获得第一故障信息，根据第一故障信息，通过第二端口发送第二故障信息，其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息，第一故障信息为第一类型故障信息，第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息，且由于第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，第二故障信息为第二类型故障信息，第二类型故障信息用于指示标准以太网协议对应的链路发生故障，因此通过传输第二故障信息的方式既可以在标准以太网协议和灵活以太网协议联合组网中通报故障，也可以为区分灵活以太网协议对应的链路发生故障和标准以太网协议对应的链路发生故障奠定基础。
在一种可能的设计中，根据第一故障信息，通过第二端口发送第二故障信息，包括： 若获得的第一类型故障信息满足第一预设条件，则根据第一故障信息，通过第二端口发送第二故障信息；其中，第一预设条件包括在第一预设时长内获得的第一类型故障信息的数量大于第一数量阈值；或者；获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔。如此，可以避免因为数量较少的故障信息导致的误操作，进一步提高操作的准确性。
在一种可能的设计中，方法还包括通过第二端口获得第三故障信息；其中，第三故障信息为第二类型故障信息；根据第三故障信息，通过第一端口发送第四故障信息；其中，第四故障信息为第一类型故障信息。如此，可以在灵活以太网网络内部传输第二类型故障信息，在灵活以以太网网络外部传输第一类型故障信息，从而可以根据故障信息的类型区分灵活以太网协议对应的链路发生故障还是标准以太网协议对应的链路发生故障。
在一种可能的设计中，根据第三故障信息，通过第一端口发送第四故障信息，包括若获得的第二类型故障信息满足第二预设条件，则根据第三故障信息，通过第一端口发送第四故障信息；其中，第二预设条件包括：在第二预设时长内获得的第三故障信息的数量大于第二数量阈值；或者；获得数量不少于第二数量阈值的第二预设码块，且获得的任两个相邻的第二预设码块之间间隔不超过第二预设码块间隔。如此，可以避免因为数量较少的故障信息导致的误操作，进一步提高操作的准确性。
在一种可能的设计中，方法还包括通过第三端口获得第五故障信息；其中，第三端口为第二类型端口，第五故障信息为第一类型故障信息或者第二类型故障信息；通过第四端口发送第五故障信息；其中，第四端口为第二类型端口。如此，在灵活以太网网络内部可以透传第一类型故障信息和第二类型故障信息，进而可以在灵活以太网网络内部传输第二类型故障信息，在灵活以以太网网络外部传输第一类型故障信息，从而可以根据故障信息的类型区分灵活以太网协议对应的链路发生故障还是标准以太网协议对应的链路发生故障。
在一种可能的设计中，方法还包括通过第五端口获得第六故障信息；其中，第五端口为第二类型端口，第六故障信息为第一类型故障信息；第五端口配置备用链路；启用第五端口对应的备用链路。可见，本申请实施例中可以实现将标准以太网协议对应的链路发生故障和灵活以太网协议对应的链路发生故障的情况通过第一类型故障信息和第二类型故障信息进行区分，从而避免标准以太网协议对应的链路发生故障触发保护倒换功能的情况；而且可以更加准确的根据灵活以太网协议网络内部的故障信息触发保护倒换功能。
在一种可能的设计中，根据第一故障信息，通过第二端口发送第二故障信息，包括根据第一故障信息，通过第二端口发送至少两个第二故障信息；其中，至少两个第二故障信息中的任两个第二故障信息之间间隔至少一个码块。如此，可以灵活设置第二故障信息的发送频率，比如将第二故障信息的发送频率设置的小于第一故障信息的发送频率，则可以节省灵活以太网协议对应的链路的传输路径的带宽。举个例子，比如第一故障信息为远端故障信息，第二故障信息为客户服务类型远端故障信息，远端故障信息为持续发送，占用带宽较大，设置间隔一定数量的码块发送一个客户服务类型远端故障信息，则可以节省带宽。
第二方面，本申请实施例提供一种通信方法，该方法包括通过第二端口获得第三故障信息；根据第三故障信息，通过第一端口发送第四故障信息；其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息；第四故障信息为第一类型故障信息； 第一类型故障信息包括本地故障信息和远端故障信息中的至少一项；第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息；第三故障信息为第二类型故障信息；第二类型故障信息用于指示标准以太网协议对应的链路发生故障。
本申请实施例中通过第二端口获得第三故障信息，根据第三故障信息，通过第一端口发送第四故障信息，由于第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，第二类型故障信息用于指示标准以太网协议对应的链路发生故障，因此通过传输第二故障信息的方式既可以在标准以太网协议和灵活以太网协议联合组网中通报故障，也可以为区分灵活以太网协议对应的链路发生故障和标准以太网协议对应的链路发生故障奠定基础；第三也可以兼容标准以太网协议网络中通过第一类型故障信息传输通报故障的方案。
该通信方法中还包括上述第一方面或第一方面中任一种方法，在此不再赘述。
第三方面，本申请实施例提供一种通信设备，通信设备包括存储器、收发器和处理器，其中：存储器用于存储指令；处理器用于根据执行存储器存储的指令，并控制收发器进行信号接收和信号发送，当处理器执行存储器存储的指令时，通信设备用于执行上述第一方面或第一方面中任一种方法。
第四方面，本申请实施例提供一种通信设备，用于实现上述第一方面或第一方面中的任意一种方法，包括相应的功能模块，分别用于实现以上方法中的步骤。
第五方面，本申请实施例提供一种计算机存储介质，计算机存储介质中存储有指令，当其在计算机上运行时，使得计算机执行第一方面或第一方面的任意可能的实现方式中的方法。

具体实施方式
图2示例性示出了本申请实施例提供的一种通信设备的结构示意图。如图2所示，通信设备1301包括两种类型的端口，分别为第一类型端口和第二类型端口，第一类型端口根据标准以太网协议传输信息，第二类型端口根据灵活以太网协议传输信息。通信设备1301可以包括一个或多个第一类型端口，以及一个或多个第二类型端口，比如图2所示第一类型端口1401、第一类型端口1402、第一类型端口1403、第二类型端口1501、第二类型端口1502和第二类型端口1503。第一类型端口对应包括接口和物理层，第一类型端口的物理层包括PMD、PMA和PCS。第二类型端口包括接口、物理层和灵活以太网协议层(英文也可以称为FlexE shim)，第二类型端口的物理层包括PMD、PMA和PCS。第一类型端口和第二类型端口中的接口具体是指电缆的连接口。可选地，第一类型端口物理层之上还包括其它层，比如MAC层等等。本申请实施例中的第一类型端口中不包括RS。可选地，第二类型端口灵活以太网协议层之上还包括其它层，比如MAC层等等。图2中仅仅示意性仅画出第一类型端口的物理层以及第二类型端口的物理层和灵活以太网协议层等。
本申请实施例中第一类型端口可以是仅支持标准以太网协议的端口，这种情况下第一类型端口仅能根据标准以太网协议传输信息。可选地，第一类型端口也可以是支持标准以太网协议和灵活以太网协议这两种协议类型的端口，这种情况下，第一类型端口是指当前使用的协议是标准以太网协议的端口。本申请实施例中第二类型端口可以是仅支持灵活以太网协议的端口，这种情况下第二类型端口仅能根据灵活以太网协议传输信息。可选地，第二类型端口也可以是支持标准以太网协议和灵活以太网协议这两种协议类型的端口，这种情况下，第二类型端口是指当前使用的协议是灵活以太网协议的端口。举个例子，比如第一端口可以支持标准以太网协议和灵活以太网协议，若第一端口在一个时间段内根据标准以太网协议传输信息，则可以在该根据标准以太网协议传输信息的时间段内称第一端口为第一类型的端口，若第一端口在一个时间段内根据灵活以太网协议传输信息，则可以在该根据灵活以太网协议传输信息的时间段内称第一端口为第二类型的端口。
可选地，本申请实施例中还可以包括第三类型端口，第三类型端口根据标准以太网协议传输信息，且第三类型端口中依次包括接口、物理层和RS，以及其它上层功能单元，比如MAC层等等。第三类型端口比如可以是图1中所示的第一以太网设备1101和第二以太网设备1201中的包括RS的端口。可选地，第三类型端口可以是仅支持标准以太网协议的端口，这种情况下第三类型端口仅能根据标准以太网协议传输信息。可选地，第三类型端口也可以是支持标准以太网协议和灵活以太网协议这两种协议类型的端口，这种情况下，第三类型端口是指当前使用的协议是标准以太网协议的端口。
如图2所示，本申请实施例中通信设备1301中还包括故障信息处理模块，故障信息 处理模块可以是一个，也可以是多个，比如图2中的故障信息模块1601、故障信息模块1602和故障信息模块1603。一种可选地实施方式中，故障信息处理模块可以设置在第一类型端口的一侧，比如设置在第一类型端口的物理层的上层中，或者也可以设置在第二类型端口的一侧，比如可以设置在第二类型端口的物理层的上层。一种可选地实施方式中，可以在第一类型端口和第二类型端口连接的链路上设置故障信息模块。本申请实施例中的故障信息处理模块可以执行本申请实施例所提供的方案，比如可以根据第一类型故障信息生成第二类型故障信息，也可以根据第二类型故障信息生成第一类型故障信息等等。
如图2所示，可选地，本申请实施例中还包括交换单元1701，各个端口可以通过交换单元1701连接。交换单元1701在通信设备2102、通信设备2103、通信设备2104中也可以称为1.5层灵活以太网协议交换单元。1.5层可以是灵活以太网协议涉及到的数据传输层，可位于开放式***互联(Open System Interconnection，OSI)7层模型的物理层和MAC层之间的数据传输层。本申请实施例中涉及到的物理层之上，或者物理层以上，或者物理层的上层等等概念均是指在模型中位于物理层上面的层，比如可以是灵活以太网协议中的1.5层灵活以太网协议层，再比如可以是MAC层等等。端口之间有的关联关系，端口之间的关联关系可以是预先配置的。比如在图2中可以设置第一类型端口1401与第二类型端口1501有关联关系，也就是说，第一类型端口1401与第二类型端口1501连接，且第一类型端口1401获得的信息(该信息默认为需要发送出去的信息；获得的信息可以是收到的其它设备发送的信息，或者是第一类型端口1401生成的信息)都要通过第二类型端口1501发送出去，而第二类型端口1501获得的信息(该信息默认为需要发送出去的信息；获得的信息可以是收到的其它设备发送的信息，或者是第一类型端口1501生成的信息))都要通过第一类型端口1401发送出去。
可选地，一个端口可以与一个或多个端口连接，但是可能有某些连接关系未处于工作状态，举个例子，比如图2中，第一类型端口1401和第二类型端口1501连接，且第一类型端口1401和第二类型端口1502也连接，但是第一类型端口1401和第二类型端口1502的连接当前也未处于工作状态，仅第一类型端口1401和第二类型端口1501的连接当前处于工作状态，也就是说这种情况下第一类型端口1401获得的信息都要通过第二类型端口1501发送出去，而第二类型端口1501获得的信息都要从第一类型端口1401发送出去，这种情况下可以称第一类型端口1401与第二类型端口1501有关联关系，而第一类型端口1401和第二类型端口1502的连接处于未激活状态，可以称未激活状态或者称关联未激活等等，也就是说本申请实施例中端口之间的关联关系是处于工作状态的关联关系。若在下一个时间段内第一类型端口1401和第二类型端口1502的连接当前也处于工作状态，也就是说这种情况下第一类型端口1401获得的信息都要通过第二类型端口1502发送出去，而第二类型端口1502获得的信息都要从第一类型端口1401发送出去，则在该下一个时间段可以称第一类型端口1401和第二类型端口1502之间有关联关系。本申请实施例中下文的两个端口之间有关联关系可以是指这两个端口之间存在连接，且连接处于工作状态，如该示例所解释的内容所示。
本申请实施例中的通信设备可以包括至少两个第一类型端口，也可以包括至少两个第二类型端口，也可以包括至少一个第一类型端口和至少一个第二类型端口。本申请实施例中还可以包括第三类型端口。图3示例性示出了本申请实施例提供的一种通信设备的结构示意图，如图3所示，本申请实施例中通信设备若包括两种类型(为第一类型端口和第二 类型端口)的端口，则第一类型端口和第二类型端口之间可以有关联关系、同一种类型的端口(比如两个第一类型端口，或者两个第二类型端口)之间可以有关联关系，比如图3中第一类型端口1401和第二类型端口1501有关联关系，第一类型端口1402和第一类型端口1403有关联关系，第二类型端口1502和第二类型端口1503有关联关系。
图4示例性示出了本申请实施例提供的一种***架构示意图，如图4所示，该通信***包括依次连接的通信设备2101、通信设备2102、通信设备2103、通信设备2104和通信设备2105。其中，通信设备2101的第三类型端口2201与通信设备2102的第一类型端口2202连接，通信设备2102的内部第一类型端口2202和第二类型端口2203有关联关系；通信设备2102的第二类型端口2203与通信设备2103的第二类型端口2204连接，通信设备2103的内部第二类型端口2204和第二类型端口2205有关联关系；通信设备2103的第二类型端口2205与通信设备2104的第二类型端口2206连接，通信设备2104的内部第二类型端口2206和第一类型端口2207有关联关系；通信设备2104的第一类型端口2207与通信设备2105的第三类型端口2208连接。
图4所示的***架构中各个通信设备中包括的端口仅仅是示意，通信设备2101、通信设备2102、通信设备2103、通信设备2104和通信设备2105中的任一个设备都可以包括至少一个第一类型端口、至少一个第二类型端口和至少一个第三类型端口中的至少一项，本申请实施例不做限制。比如，通信设备2101和通信设备2105可以只包括第三类型端口，这种情况下，通信设备2101和通信设备2105也可以称为以太网设备，也可以称为用户侧设备；可选地通信设备2101和通信设备2105还可以包括至少一个第一类型端口和/或至少一个第二类型端口等。通信设备2103中可以仅包括第二类型端口，可选地通信设备2103还可以包括至少一个第一类型端口和/或至少一个第三类型端口等。通信设备2102和通信设备2104中包括至少一个第一类型端口和至少一个第二类型端口，从而可以用于将第一类型端口传输的信息通过第二类型端口传输。可选地通信设备2102还可以包括至少一个第三类型端口。
可选地，图4中所示的***架构中，通信设备2102和通信设备2104可以称为PE节点，英文可以写为provider edge，是指运营商网络边缘与用户连接的网络设备，该PE节点上可配置网络之间或网络内设备之间的端口(Network to Network interface，NNI)和用户侧端口，用户侧端口即网络与用户连接的部分的端口(User network interface，UNI)。可选地，用户侧端口可以是第一类型端口，网络之间或网络内设备之间的端口可以是第二类型端口。通信设备2103英文可以称为provider，为运营商网络内的网络设备，可以称为P节点，该P节点上可以仅配置NNI的网络端口。可选地，通信设备2102和通信设备2104之间可以包括一个或多个通信设备2103，也就是说两个PE节点中的每个PE节点连接P节点和以太网设备，两个PE节点之间可以包括至少一个P节点，在这种***架构下，可以将标准以太网协议对应的信息通过灵活以太网协议进行传输，从而可以更加快速高效的传输数据，实现在标准以太网网络架构下复用灵活以太网协议的目的。
本申请实施例中，如图4所示，通信设备2101和通信设备2105中的第三类型端口中包括RS，为了提高信息传输效率，可选地，可以在通信设备2102、通信设备2103和通信设备2104中的第一类型端口和第二类型端口中不配置RS。本申请实施例中端口之间可互相传输数据，可选地，端口与端口之间可以包括两种类型的链路，一种类型的链路用于从一个端口发送信息至另一个端口，另一种类型的链路用于使该一个端口接收该另一个端口 发送的信息。比如，第三类型端口2201和第一类型端口2202之间可以包括两种类型的链路，可以分别称为第一类型链路和第二类型链路，第一类型链路用于传输从第三类型端口2201发送至第一类型端口2202的信息，第二类型链路用户传输从第一类型端口2202发送至第三类型端口2201的信息。具体实施中，可选地，第一类型链路和第二类型链路可以是一对光纤，分别用于接收和发送，也就是说一对光纤中的一根可以称为第一类型链路，另一根可以称为第二类型链路。
图5示例性示出了基于图4所示***架构的一种故障信息传输路径示意图，如图5所示，在标准以太网协议中引入FlexE网络后，若在从通信设备2101至通信设备2102的链路上发生故障，比如第三类型端口2201向第一类型端口2202发送信息的链路发生故障，第一类型端口2202检测到链路故障后，第一类型端口2202的物理层会生成本地故障信息(Local Fault，LF)。第一类型端口2202检测到链路故障有多种实现方式，比如第一类型端口2202在预设时长内未收到信息。由于第一类型端口中没有RS，且通信设备2102、通信设备2103、通信设备2104中的第一类型端口和第二类型端口都没有RS，因此第一类型端口2202生成的LF会传输至通信设备2102的1.5层交换单元，交换到第二类型端口2203，由于第二类型端口也无RS，因此LF信息经过灵活以太网协议网络传输，会一直透传至通信设备2105的第三类型端口2208的RS。也就是说，第一类型端口2202生成的LF会沿着第二类型端口2203、第二类型端口2204、第二类型端口2205、第二类型端口2206、第一类型端口2207，最终传至第三类型端口2208的RS。第三类型端口2208的RS在检测到LF信息时，可以停止第三类型端口2208的MAC层的数据发送，并生成RF信息，持续下插到第三类型端口2208的PCS层。该RF信息也沿着第一类型端口2207、第二类型端口2206、第二类型端口2205、第二类型端口2204、第二类型端口2203、第一类型端口2202一直传输至第三类型端口2201的RS中，第三类型端口2201的RS在检测到RF信息时，则停止第三类型端口2201的MAC层的数据发送，生成Idle控制块，持续下插到第三类型端口2201的PCS层。
通过图5所示的示例可以看出，本申请实施例中第一类型端口之间的链路发生故障所生成的故障信息(比如LF和/或RF)会在灵活以太网协议的网络内部传输，由于现有技术中第一类型的端口所生成的LF的频率较高，且RF会持续传输，因此第一类型端口之间的链路发生故障所生成的故障信息占用了较大比例的带宽。基于这个问题，本申请实施例中通过第一端口获得第一故障信息，根据第一故障信息，通过第二端口发送第二故障信息，其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息，第一故障信息为第一类型故障信息，第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息，且由于第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，而本地故障信息和远端故障信息的传输方式占用的传输路径的带宽较大，因此通过传输第二故障信息的方式既可以在标准以太网协议和灵活以太网协议联合组网中通报故障，也可以节省灵活以太网协议对应的链路的传输路径的带宽。
进一步，在标准以太网协议中引入灵活以太网协议网络后，第二类型端口的物理层在检测到故障后也会生成本地故障信息(比如LF)。比如FlexE Implementation Agreement 1.0规范约定，在FlexE端口(即第二类型端口)上检测到信息失效(链路故障)、灵活以太网协议组开销帧(英文可以称为FlexE Group Overhead Frame)同步锁定失败、高误码率、属于同一个灵活以太网协议组(英文可以称为FlexE Group)的多个PHY的对齐失败、在属 于同一个FlexE Group但不同灵活以太网协议物理端口上接收到的灵活以太网协议组开销帧(英文可以称为FlexE Group Overhead Frame)中的PHY映射表、PHY编号、FlexE Group编号字段存在不一致的问题、或多个PHY之间的接收时钟偏差过大，该FlexE物理端口(第二类型端口)上的所有灵活以太网协议客户(英文可以称为FlexE Client)都持续下插以太网LF故障信息。
可选地，可以在配置有第二类型端口的通信设备上配置保护倒换功能，保护倒换功能英文可以称为protection switching，也称为自动保护倒换(Automatic Protection Switching，APS)，具体可以是指数据流量的传输因故障或人工干预的方式从一条工作路径切换到对应该工作路径的保护路径(比如从工作链路切换至备用链路)。通信设备中若配置有保护倒换功能，则在检测到LF时开启保护倒换功能。灵活以太网协议中配置保护倒换功能是为了提供灵活以太网协议下的自愈机制，即若灵活以太网协议网络内部出现故障，可以通过保护倒换功能实现自愈。
图6示例性示出了基于图4所示***架构的另一种故障信息传输路径示意图，如图6所示，本申请实施例中通信设备之间可以包括至少一条链路，比如通信设备2103和通信设备2104之间包括两条链路，分别为第二类型端口2205和第二类型端口2206之间的链路，以及第二类型端口2301和第二类型端口2302之间的链路。再比如通信设备2103和通信设备2104之间包括两条链路，分别为第二类型端口2205和第二类型端口2206之间的链路，第二类型端口2205和第二类型端口2303之间的链路(此示例图中未示出)。
在一个时间段内可选地通信设备2103和通信设备2104之间只有一条链路处于工作状态，也可以称当前处于工作状态的链路为工作链路，当前未处于工作状态的链路称为备用链路。比如在一个时间段内第二类型端口2205和第二类型端口2206之间的链路处于工作状态，即通信设备2103和通信设备2104之间所需要传输的数据都通过第二类型端口2205和第二类型端口2206之间的链路进行传输，则第二类型端口2205和第二类型端口2206之间的链路称为工作链路，当前未处于工作状态的第二类型端口2301和第二类型端口2302之间的链路称为备用链路；在下一个时间段内第二类型端口2301和第二类型端口2302之间的链路处于工作状态，则第二类型端口2301和第二类型端口2302之间的链路称为工作链路，第二类型端口2205和第二类型端口2206之间的链路称为备用链路。
由于通信设备中若配置有保护倒换功能，则在检测到LF时开启保护倒换功能，如图6所示，在通信设备2104上配置保护倒换功能，比如在通信设备2103和通信设备2104之间设置两条链路，分别为第二类型端口2205和第二类型端口2206之间的链路，以及第二类型端口2301和第二类型端口2302之间的链路。当前工作链路为第二类型端口2205和第二类型端口2206之间的链路。可选地，保护倒换功能可以配置在第二类型端口的物理层之上。可选地，保护倒换功能可以在每个第二类型端口的灵活以太网协议层配置。
一种可能发生故障的情况下，在图6中，若通信设备2103和通信设备2104之间的链路发生故障，比如第二类型端口2205向第二类型端口2206发送信息的链路出现故障，则第二类型端口2206的物理层会生成LF，第二类型端口2206的灵活以太网协议层(图中标识为FlexE shim)接收到LF，则启动保护倒换功能，即启用第二类型端口2206对应的备用链路。也就是说将工作链路从第二类型端口2205和第二类型端口2206之间的链路切换至第二类型端口2301和第二类型端口2302之间的链路，即启用第二类型端口2301和第二类型端口2302之间的链路作为工作链路，第二类型端口2205和第二类型端口2206之 间的链路变更为备用链路。进一步的第二类型端口2204与第二类型端口2301之间有关联关系，而第二类型端口2204和第二类型端口2205的连接处于未激活状态。可见，当灵活以太网协议内部有故障时，灵活以太网协议启用备用链路可以继续进行工作，这个能力也可以称为灵活以太网协议的自愈能力。当启用第二类型端口2205的备用链路的情况下，第二类型端口2302不会再因为第二类型端口2205向第二类型端口2206发送信息的链路出现故障而收到LF。
另一种可能发生故障的情况下，如图6所示，若第三类型端口2201向第一类型端口2202发送信息的链路发生故障，第一类型端口2202检测到链路故障后，第一类型端口2202的物理层会生成LF，LF会传输至通信设备2104，通信设备2104检测到LF后，会触发保护倒换功能，即将第二类型端口2206对应的链路切换至备用链路，也就是说将工作链路从第二类型端口2205和第二类型端口2206之间的链路切换至第二类型端口2301和第二类型端口2302之间的链路，即启用第二类型端口2301和第二类型端口2302之间的链路作为工作链路，第二类型端口2205和第二类型端口2206之间的链路变更为备用链路。在这种情况下，由于第一类型端口2202的物理层在继续生产LF，因此即使在通信设备2104启动保护倒换功能后仍然会收到LF，这种情况下通信设备2104可能会继续启用保护倒换功能，即将工作链路再从第二类型端口2301和第二类型端口2302之间的链路切换至第二类型端口2205和第二类型端口2206之间的链路。可见，由于通信设备收到的LF信息是第一类型端口之间发生故障时生成的，因此该LF即使在通信设备2104启动自动保护倒换功能后仍旧发送通信设备2104，结果导致反复倒换工作链路，出现倒换震荡的情况。也就是说，灵活以太网协议下的保护倒换功能本来是针对灵活以太网协议内部的故障信息实现自愈功能，但是灵活以太网协议网络外的故障信息一旦进入灵活以太网协议，可能会使通信设备误以为该故障信息是灵活以太网协议网络内的故障信息，从而引起返回倒换工作链路，出现倒换振动的情况。针对这种情况，本申请实施例中，由于第二故障信息为第二类型故障信息，且还可以通过第二故障信息将标准以太网协议对应的链路发生故障指示出来，从而可以为区分灵活以太网协议对应的链路发生故障和标准以太网协议对应的链路发生故障奠定基础。
基于上述内容，本申请实施例提供一种通信方法，图7示例性示出了本申请实施例提供的一种通信方法的流程示意图，如图7所示，该方法包括步骤3101至步骤3102。
步骤3101，通信设备通过第一端口获得第一故障信息；其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息；第一故障信息为第一类型故障信息，第一类型故障信息包括本地故障信息和远端故障信息中的至少一项。可选地，通信设备包括多个第一类型端口，第一端口为多个第一类型端口中的、且与至少一个第二类型端口有关联关系的第一类型端口。
本申请实施例中第一类型端口可以是仅支持标准以太网协议的端口，也可以是支持标准以太网协议和灵活以太网协议这两种协议类型的端口，这种情况下，第一类型端口是指当前使用的协议是标准以太网协议的端口。本申请实施例中第二类型端口可以是仅支持灵活以太网协议的端口，也可以是支持标准以太网协议和灵活以太网协议这两种协议类型的端口，这种情况下，第二类型端口是指当前使用的协议是灵活以太网协议的端口。示例可参见上述图2所示相关内容，在此不再赘述。

本申请实施例中可选地，通信设备通过第一类型端口获得第一类型故障信息的情况下，若需要通过第二类型端口发送出去，则通过第二类型端口发送第二类型故障信息。
本申请实施例中通过第一端口获得第一故障信息，根据第一故障信息，通过第二端口发送第二故障信息，其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息，第一故障信息为第一类型故障信息，第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息，且由于第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，第二故障信息为第二类型故障信息，第二类型故障信息用于指示标准以太网协议对应的链路发生故障，因此通过传输第二故障信息的方式既可以在标准以太网协议和灵活以太网协议联合组网中通报故障，也可以为区分灵活以太网协议对应的链路发生故障和标准以太网协议对应的链路发生故障奠定基础。
基于上述内容，本申请实施例提供另一种通信方法，图8示例性示出了本申请实施例提供的一种通信方法的流程示意图，如图8所示，该方法包括步骤3401至步骤3402。
可选地，执行步骤3401至步骤3402的通信设备和执行步骤3101和步骤3102的通信设备可以是两个不同的通信设备，这种情况下，执行步骤3401至步骤3402的通信设备中包括的第一端口与执行步骤3101和步骤3102的通信设备中的第一端口为不同的两个端口，执行步骤3401至步骤3402的通信设备中包括的第二端口与执行步骤3101和步骤3102的通信设备中的第二端口为不同的两个端口。可选地，执行步骤3101至步骤3102的通信设备可以是图8中的通信设备2102，执行步骤3401至步骤3402的通信设备可以是图8中的通信设备2104，这种情况下，执行步骤3101至步骤3102的通信设备中的第一端口可以是第一类型端口2202，执行步骤3101至步骤3102的通信设备中的第二端口可以是第二类型端口2203；执行步骤3401至步骤3402的通信设备中的第一端口可以是第一类型端口2207，执行步骤3401至步骤3402的通信设备中的第二端口可以是第二类型端口2206。
可选地，执行步骤3401至步骤3402的通信设备也可以是上述执行步骤3101和步骤3102的通信设备，这种情况下，执行步骤3401至步骤3402的通信设备中包括的第一端口与执行步骤3101和步骤3102的通信设备中的第一端口可以为不同的两个端口也可以为相同的两个端口，执行步骤3401至步骤3402的通信设备中包括的第二端口与执行步骤3101和步骤3102的通信设备中的第二端口可以为不同的两个端口也可以为相同的两个端口。这种情况下，步骤3401和步骤3402可以在上述步骤3101和步骤3102之后执行，也可以在步骤3101和步骤3102之前执行。
步骤3401，通信设备通过第二端口获得第三故障信息；根据第三故障信息；第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息；第三故障信息为第二类型故障信息；第二类型故障信息用于指示标准以太网协议对应的链路发生故障；可选地，通信设备包括多个第二类型端口，第二端口为多个第二类型端口中的、且与至少一个第一类 型端口有关联关系的第二类型端口。
本申请实施例中可选地，通信设备通过第二类型端口获得第二类型故障信息的情况下，若需要通过第一类型端口发送出去，则通过第一类型端口发送第一类型故障信息。
本申请实施例中第一类型端口可以是仅支持标准以太网协议的端口，也可以是支持标准以太网协议和灵活以太网协议这两种协议类型的端口，这种情况下，第一类型端口是指当前使用的协议是标准以太网协议的端口。本申请实施例中第二类型端口可以是仅支持灵活以太网协议的端口，也可以是支持标准以太网协议和灵活以太网协议这两种协议类型的端口，这种情况下，第二类型端口是指当前使用的协议是灵活以太网协议的端口。示例可参见上述图2所示相关内容，在此不再赘述。
步骤3402，通信设备通过第一端口发送第四故障信息；其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息；第四故障信息为第一类型故障信息；第一类型故障信息包括本地故障信息和远端故障信息中的至少一项。可选地，该步骤的通信设备可以是上述图2至图6中包括两种类型端口的通信设备，比如可以是上述图2至图6中的通信设备2102和通信设备2104。在步骤3102中，第一端口和第二端口之间有关联关系，即第一端口获得的信息都通过第二端口传输出去，第二端口获得的信息都从第一端口传输出去。可选地，通信设备包括多个第一类型端口，第一端口为多个第一类型端口中的、且与至少一个第二类型端口有关联关系的第一类型端口。
本申请实施例中通过第二端口获得第三故障信息，根据第三故障信息，通过第一端口发送第四故障信息，由于第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，第二类型故障信息用于指示标准以太网协议对应的链路发生故障，因此通过传输第二故障信息的方式既可以在标准以太网协议和灵活以太网协议联合组网中通报故障，也可以为区分灵活以太网协议对应的链路发生故障和标准以太网协议对应的链路发生故障奠定基础；第三也可以兼容标准以太网协议网络中通过第一类型故障信息传输通报故障的方案。
基于图7和图8所描述的通信方法，下面进一步对上述图7和图8中的几种可能的设计进行阐述，下面的方法项实施例均适用于上述图7和图8所描述的方案。
本申请实施例中，由于本地故障信息和远端故障信息是持续传递的66b block，因此会占用了传输路径的带宽。而应用本申请实施例的方案可以在灵活以太网协议内传输第二类型故障信息，可以灵活设置第二故障信息的发送频率，比如将第二故障信息的发送频率设置的小于第一故障信息的发送频率，则可以节省灵活以太网协议对应的链路的传输路径的带宽。举个例子，比如第一故障信息为远端故障信息，第二故障信息为客户服务类型远端故障信息，远端故障信息为持续发送，占用带宽较大，设置间隔一定数量的码块发送一个客户服务类型远端故障信息，则可以节省带宽。进一步，可将节省的网络带宽用于承载其他业务，包括统计复用等)，还由于第二类型故障信息用于指示标准以太网协议对应的链路发生故障，因此可以避免由于标准以太网协议对应的链路发生故障的情况下误触发保护倒换功能。进一步，本申请实施例中，在采用FlexE组网的情况下，既可以支持标准以太网802.3规范的基于本地故障信息和/或远端故障信息进行链路(英文也可以称为LINK)协商(IEEE 802.3章节81.3.4)，也可以保证灵活以太网协议网络内自愈机制的正确实施。
一种可选地实施方式中，上述步骤3101中，通信设备通过第一端口获得第一故障信息，可以是通信设备通过第一端口的物理层生成本地故障信息；或者可以是通信设备通过 第一端口接收的远端故障信息。举个例子，比如第一端口为第一类型端口2202，图6中，第三类型端口2201发送信息至第一类型端口2202的链路出现故障，则第一类型端口2202的物理层生成本地故障信息。再比如，第一类型端口2202发送信息至第三类型端口2201的链路出现故障，则第三类型端口2201的物理层生成本地故障信息，第三类型端口2201的RS检测到本地故障信息后，生成远端故障信息，该远端故障信息传输至第一类型端口2202。
本申请实施例中可以定义两种类型的第二类型故障信息，分布为客户服务类型本地故障信息和客户服务类型远端故障信息。客户服务类型本地故障信息英文可以称为Client Service Fault，可以简写为CSF，下图9中为表达更加清晰，采用CSF来表示客户服务类型本地故障信息。客户服务类型远端故障信息英文可以称为Remote Client Service Fault，可以简写为RCSF，下图9中为表达更加清晰，采用RCSF来表示客户服务类型远端故障信息。客户服务类型本地故障信息和客户服务类型远端故障信息中的客户服务类型是一种比较上位的说法，具体可以是为客户服务的业务的相关内容；客户服务类型本地故障信息和客户服务类型远端故障信息中的客户服务类型对本申请实施例中的第二类型故障信息不具有限定意义，仅仅用于与本申请实施例中的本地故障信息(英文简写LF)和远端故障信息(英文简写RF)从名字上进行区分。
可选地，根据第一故障信息，通过第二端口发送第二故障信息，包括：根据第一故障信息生成第一故障信息对应的第二故障信息，并通过第二端口发送第二故障信息。其中，第一故障信息为本地故障信息，则第一故障信息对应的第二故障信息为客户服务类型本地故障信息，第一故障信息为远端故障信息，则第一故障信息对应的第二故障信息为客户服务类型远端故障信息。也就是说，可选地，第一类型故障信息为本地故障信息，则第一类型故障信息对应的第二类型故障信息为客户服务类型本地故障信息，第一类型故障信息为远端故障信息，则第一类型故障信息对应的第二类型故障信息为客户服务类型远端故障信息；相应地，第二类型故障信息为客户服务类型本地故障信息，则第二类型故障信息对应的第一类型故障信息为本地故障信息，第二类型故障信息为客户服务类型远端故障信息，则第二类型故障信息对应的第一类型故障信息为远端故障信息。
可选地，根据第一故障信息生成第一故障信息对应的第二故障信息可以是新生成第二故障信息，也可以是在第一故障信息中增加指示信息生成的，该指示信息用于指示标准以太网协议对应的链路发生故障。也就是说，根据第一类型故障信息生成第一类型故障信息对应的第二类型故障信息可以是新生成第二类型故障信息，也可以是在第一类型故障信息中增加指示信息生成的，该指示信息用于指示标准以太网协议对应的链路发生故障。
可选地，上述步骤3102中，通信设备根据第一故障信息，通过第二端口发送第二故障信息，包括：若获得的第一类型故障信息满足第一预设条件，则根据第一故障信息，通过第二端口发送第二故障信息；其中，第一预设条件包括：获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔。本申请实施例中在满足“获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔”的条件下发送第二故障信息，通信设备可以持续检测获得的第一预设码块的数量，若检测到不满足“获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔”的条件，则停止发送第二故障信息。如此，可以避免因为数量较少的故 障信息导致的误操作，进一步提高操作的准确性。
举个例子，第一66 bit block控制块为上述第一预设码块，第一预设码块间隔为128个码块，第一数量阈值为4个，当在检测到4个第一66 bit block(也可以称为第一66比特块)控制块，且任意相邻两个第一66 bit block控制块之间间隔不超过128个码块，则根据第一故障信息，通过第二端口发送第二故障信息。具体检测过程中，可以在检测到第1个第一66 bit block控制块后，计数器记为第1个码块，后面128个block里面如果再检测到1个，计数器记为第2个，如果在后面128个block里面没有再检测到1个第一66 bit block控制块，事件记录清零(即计数器清零)；当下次再检测到第一66 bit block控制块时重新将计数器从1开始计数；如此下来，连续累计检测到4个有效第一66 bit block控制块(即计数器达到4)，则认为获得了LF或RF信息。通信设备持续检测，在计数器的值不小于4的情况下通信设备发送第二故障信息，在计数器的值小于4的情况下停止发送第二故障信息，也就是说，相对应的，如果没有达到条件“获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔”，则可以认为故障清除，则不再发送第二故障信息。举个例子，比如通信设备在连续128个码块内没有检测到第一66 bit block控制块，则认为故障清除。
可选地，通信设备根据第一故障信息，通过第二端口发送第二故障信息，包括：若在第一预设时长内获得的第一故障信息的数量大于第一数量阈值，则：根据第一故障信息，通过第二端口发送第二故障信息。可选地，第一故障信息也可以是第一预设码块。也就是说，若获得的第一类型故障信息满足第一预设条件，则根据第一故障信息，通过第二端口发送第二故障信息；其中，第一预设条件包括：在第一预设时长内获得的第一类型故障信息的数量大于第一数量阈值。在这种情况下获得的第一类型故障信息是第一故障信息。本申请实施例中在满足“在第一预设时长内获得的第一故障信息的数量大于第一数量阈值”的条件下发送第二故障信息，通信设备持续检测获得的第一故障信息的数量，若检测到不满足“在第一预设时长内获得的第一故障信息的数量大于第一数量阈值”的条件，则停止发送第二故障信息。
举个例子，第一66 bit block控制块为上述第一预设码块，第一数量阈值为4个，在确定获得第一数量阈值的第一预设码块所使用的时长不大于第一预设时长，比如获得连续4个第一66 bit block的时长不大于第一预设时长，则发送第二故障信息。可选地，通信设备持续检测获得的第一预设码块，若获得连续4个第一66 bit block的时长大于第一预设时长，则确定满足“在第一预设时长内获得的第一故障信息的数量大于第一数量阈值”的条件，停止发送第二故障信息。
可选地，方法还包括通信设备通过第五端口获得第六故障信息；其中，第五端口为第二类型端口，第六故障信息为第一类型故障信息；第五端口配置备用链路；启用第五端口对应的备用链路。可选地，本申请实施例中若在通信设备中配置了保护倒换功能，在通信设备在接收到灵活以太网协议网络内的故障信息的情况下开启保护倒换功能，在接收到灵活以太网协议网络外的故障信息的情况下不开启倒换功能。本申请实施例中第二类型故障信息可以指示标准以太网协议对应的链路发生故障，因此当通信设备接收到第二类型故障信息时，则不开启保护倒换功能，当接收到第一类型故障信息时，则开启保护倒换功能。可见，本申请实施例中可以实现将标准以太网协议对应的链路发生故障和灵活以太网协议对应的链路发生故障的情况通过第一类型故障信息和第二类型故障信息进行区分，从而避 免标准以太网协议对应的链路发生故障触发保护倒换功能的情况。可选地，启用第五端口对应的备用链路，可以是参照上述图6所示的通信设备2103和通信设备2104之间的启用备用链路的过程，在此不再赘述。
本申请实施例中当将故障信息从标准以太网协议网络传输进灵活以太网协议网络，则可以根据第一类型故障信息生成第二类型故障信息，并在灵活以太网协议网络传输第二类型故障信息。相应地，若将故障信息从灵活以太网协议网络传输进标准以太网协议网络，则可以根据第二类型故障信息生成第一类型故障信息，并在标准以太网协议网络传输第一类型故障信息。可选地，本申请实施例中通过第二端口获得第三故障信息；其中，第三故障信息为第二类型故障信息；根据第三故障信息，通过第一端口发送第四故障信息；其中，第四故障信息为第一类型故障信息。如此，可以在灵活以太网网络内部传输第二类型故障信息，在灵活以以太网网络外部传输第一类型故障信息，从而可以根据故障信息的类型区分灵活以太网协议对应的链路发生故障还是标准以太网协议对应的链路发生故障。本申请实施例中故障信息是用于指示链路出现故障的信息，是一种上位的称呼，故障信息可以包括第一类型故障信息和/或第二类型故障信息。
可选地，根据第三故障信息，通过第一端口发送第四故障信息，包括：根据第三故障信息生成第三故障信息对应的第四故障信息，并通过第一端口发送第四故障信息。其中，则第三故障信息为客户服务类型本地故障信息，第三故障信息对应的第四故障信息为本地故障信息；第三故障信息为客户服务类型远端故障信息，第三故障信息对应的第四故障信息为远端故障信息。
可选地，根据第三故障信息生成第三故障信息对应的第四故障信息可以是新生成第四故障信息，也可以是将第三故障信息中的指示信息去除后得到的，该指示信息用于指示标准以太网协议对应的链路发生故障。也就是说，根据第二类型故障信息生成第二类型故障信息对应的第一类型故障信息可以是新生成第一类型故障信息，也可以是将第二类型故障信息中的指示信息去除之后得到的，该指示信息用于指示标准以太网协议对应的链路发生故障。
可选地，通信设备根据第三故障信息，通过第一端口发送第四故障信息，包括：若获得的第二类型故障信息满足第二预设条件，则根据第三故障信息，通过第一端口发送第四故障信息；其中，第二预设条件包括：获得数量不少于第二数量阈值的第二预设码块，且获得的任两个相邻的第二预设码块之间间隔不超过第二预设码块间隔。也就是说，本申请实施例中在满足“获得数量不少于第二数量阈值的第二预设码块，且获得的任两个相邻的第二预设码块之间间隔不超过第二预设码块间隔”的条件下发送第四故障信息，通信设备持续检测获得的第二预设码块的数量，若检测到不满足“获得数量不少于第二数量阈值的第二预设码块，且获得的任两个相邻的第二预设码块之间间隔不超过第二预设码块间隔”的条件，则停止发送第四故障信息。如此，可以避免因为数量较少的故障信息导致的误操作，进一步提高操作的准确性。
举个例子，第二66 bit block控制块为上述第二预设码块，第二预设码块间隔为128个码块，第二数量阈值为4个，当在检测到4个第二66 bit block(也可以称为第二66比特块)控制块，该第二66 bit block控制块中可以承载用于指示标准以太网协议对应的链路出现故障的指示信息。且任意相邻两个第二66 bit block控制块之间间隔不超过128个码块，则根据第三故障信息，通过第一端口发送第四故障信息。具体检测过程中，可以在检测到 第1个第二66 bit block控制块后，计数器记为第1个码块，后面128个block里面如果再检测到1个，计数器记为第2个，如果在后面128个block里面没有再检测到1个第二66 bit block控制块，事件记录清零(即计数器清零)，当下次再检测到第二66 bit block控制块时重新从1开始计数；如此下来，连续累计检测到4个有效第二66 bit block控制块，即计数器达到4，则认为获得了LF或RF信息。通信设备持续检测，在计数器的值不小于4的情况下通信设备发送第四故障信息，在计数器的值小于4的情况下停止发送第四故障信息，也就是说，相对应的，如果没有达到条件“获得数量不少于第二数量阈值的第二预设码块，且获得的任两个相邻的第二预设码块之间间隔不超过第二预设码块间隔”，则可以认为故障清除，则不再发送第四故障信息。举个例子，比如通信设备在连续128个码块内没有检测到第二66 bit block控制块，则认为故障清除。
可选地，通信设备根据第三故障信息，通过第一端口发送第四故障信息，包括：若在第二预设时长内获得的第三故障信息的数量大于第二数量阈值，则：根据第三故障信息，通过第一端口发送第四故障信息。可选地，第三故障信息也可以是第二预设码块。也就是说，若获得的第二类型故障信息满足第二预设条件，则根据第三故障信息，通过第一端口发送第四故障信息；其中，第二预设条件包括：在第二预设时长内获得的第三故障信息的数量大于第二数量阈值。在这种情况下获得的第二类型故障信息是第三故障信息。本申请实施例中在满足“在第二预设时长内获得的第三故障信息的数量大于第二数量阈值”的条件下发送第四故障信息，通信设备持续检测获得的第三故障信息的数量，若检测到不满足“在第二预设时长内获得的第三故障信息的数量大于第二数量阈值”的条件，则停止发送第四故障信息。
举个例子，第二66 bit block控制块为上述第二预设码块，第二数量阈值为4个，在确定获得第二数量阈值的第二预设码块所使用的时长不大于第二预设时长，比如获得连续4个第二66 bit block的时长不大于第二预设时长，则发送第四故障信息。可选地，通信设备持续检测获得的第二预设码块，若获得连续4个第二66 bit block的时长大于第一预设时长，则确定满足“在第二预设时长内获得的第二故障信息的数量大于第二数量阈值”的条件，停止发送第四故障信息。
本申请实施例中，可选地，方法还包括：通过第三端口获得第五故障信息；其中，第三端口为第二类型端口，第五故障信息为第一类型故障信息或者第二类型故障信息；通过第四端口发送第五故障信息；其中，第四端口为第二类型端口。如此，在灵活以太网网络内部可以透传第一类型故障信息和第二类型故障信息，进而可以在灵活以太网网络内部传输第二类型故障信息，在灵活以以太网网络外部传输第一类型故障信息，从而可以根据故障信息的类型区分灵活以太网协议对应的链路发生故障还是标准以太网协议对应的链路发生故障。也就是说，若两个第二类型端口之间有关联关系，比如第三端口和第四端口之间有关联关系，即第三端口获得的信息都通过第四端口传输出去，第四端口获得的信息都从第三端口传输出去，且第三端口为第二类型端口，第四端口为第二类型端口，则第三端口和第四端口可以透传获得的第一类型故障信息或第二类型故障信息。比如第三端口可以是上述图4至图6中的通信设备2103中的第二类型端口2204，第四端口可以是上述图4至图6中的通信设备2103中的第二类型端口2205，第二类型端口2204和第二类型端口2205可以透传获得的第一类型故障信息或第二类型故障信息。再比如第三端口和第四端口还可以是上述图4至图6中通信设备2102中的两个第二类型端口。
本申请实施例中，可选地，方法还包括：通过第六端口获得第七故障信息；其中，第六端口为第一类型端口，第七故障信息为第一类型故障信息；通过第七端口发送第七故障信息；其中，第七端口为第一类型端口。也就是说，若两个第一类型端口之间有关联关系，比如第六端口和第七端口之间有关联关系，即第六端口获得的信息都通过第七端口传输出去，第七端口获得的信息都从第六端口传输出去，且第六端口为第一类型端口，第七端口为第一类型端口，则第六端口和第七端口可以透传获得的第一类型故障信息或第二类型故障信息。比如第六端口可以是上述图4中的通信设备2102中的第一类型端口3201，第七端口可以是上述图4中的通信设备2102中的第一类型端口3202，第一类型端口3201和第一类型端口3202可以透传获得的第一类型故障信息或第二类型故障信息，图4中第一类型端口3201和第一类型端口3202有关联关系，第一类型端口3201可以连接其它通信设备的第一类型端口，第二类型端口3202也可以连接其它通信设备的第一类型端口。
基于上述内容，为了进一步描述本申请实施例所提供的方案，本申请实施例中提供一种通信方法流程示意图，图9示例性示出了本申请实施例中提供的基于图4所示***结构的一种故障信息传输路径示意图，如图9所示，可以在通信设备中配置故障信息处理模块，比如在通信设备2102中的第一类型端口2202、第一类型端口3201和第一类型端口3202中的物理层上方配置故障信息处理模块，在通信设备2104中的第一类型端口2207的物理层上层配置故障信息处理模块。
若通信设备2101的第三类型端口2201发送信息至通信设备2102的第一类型端口2202的链路出现故障，则第一类型端口2202的物理层生成本地故障信息(属于第一类型故障信息，图中示意性写为LF)，可选地，通信设备2102通过第一类型端口2202获得第一类型故障信息的情况下，比如在满足第一预设条件时，发送客户服务类型本地故障信息(属于第二类型故障信息，图中示意性写为CSF)。比如可以通过故障信息处理模块来做，当故障信息处理模块接收到第一类型故障信息的情况下，比如在满足第一预设条件时，故障信息处理模块发送客户服务类型本地故障信息。其中，第一预设条件为“在第一预设时长内获得的第一类型故障信息的数量大于第一数量阈值”或“获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔”。
举个例子说明“获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔”的条件时，发送客户服务类型本地故障信息，比如，设置计数器，当检测到第一预设码块时，将计数器加1，当前计数器值为1，收到第二个第一预设码块时，若该第一预设码块与前一个相邻的第一预设码块之间的间隔不大于128个码块在，则将计数器加1；若该第一预设码块与前一个相邻的第一预设码块之间的间隔大于128个码块，则将计数器清零。预设第一数量阈值为4，则当计数器为不小于4的情况下，开始发送客户服务类型本地故障信息，可选地，可以是间隔一定数量的码块发送一个客户服务类型本地故障信息。当计数器为小于4的情况下，则不再发送客户服务类型本地故障信息。
进一步，第一类型端口2202生成的客户服务类型本地故障信息沿着第二类型端口2203、第二类型端口2204、第二类型端口2205、第二类型端口2206传输(也可以称为透传)至通信设备2104。由于通信设备需要将第二类型端口2206传输的信息通过第一类型端口2207传输出去，因此通信设备2104根据获得的客户服务类型本地故障信息，可以在 确定获得的客户服务类型本地故障信息满足第二预设条件时，生成本地故障信息，并将本地故障信息通过第一类型端口2207传输至通信设备2105的第三类型端口2208。可选地，可以是通信设备2104中的故障信息处理模块根据获得的客户服务类型本地故障信息，生成本地故障信息。相对应地，通信设备2104在获得的客户服务类型本地故障信息不满足第二预设条件时，可以不再通过第一类型端口2207发送本地故障信息。其中，第二预设条件可以是“在第二预设时长内获得的第二类型故障信息的数量大于第二数量阈值”或者“获得数量不少于第二数量阈值的第二预设码块，且获得的任两个相邻的第二预设码块之间间隔不超过第二预设码块间隔”。
进一步，通信设备2105的通过第三类型端口2208获得本地故障信息后，可以在确定获得的本地故障信息满足条件第一预设条件的情况下，第三类型端口2208中的RS下发远端故障信息，可以是持续下发远端故障信息。相对应的，若通信设备2105确定获得的本地故障信息不满足第一预设条件，则不再下发远端故障信息。
进一步，可选地，通信设备2104的第一类型端口2207在获得远端故障信息之后，确定获得的远端故障信息满足第一预设条件，通信设备2104生成客户服务类型远端故障信息并通过第二类型端口2206发送。相应地，若通信设备2105确定获得的远端故障信息不满足第一预设条件，则通信设备2105不发送客户服务类型远端故障信息。
进一步，可选地，通信设备2104通过第二类型端口2206发送的客户服务类型远端故障信息沿着第二类型端口2205、第二类型端口2204、第二类型端口2203一直透传至通信设备2102。由于通信设备2102需要将第二类型端口2203获得的信息通过第一类型端口2202传输出去，因此通信设备2104根据在获得客户服务类型远端故障信息的情况下，且确定获得的客户服务类型远端故障信息满足第二预设条件，通过第一类型端口2202发送远端故障信息。相应地，若确定获得的客户服务类型远端故障信息不满足第二预设条件，则不通过第一类型端口2202发送远端故障信息。
基于图9所示的实施例，本申请实施例中提供另外一种可选地实施方式，如图9所示，若通信设备2101的第三类型端口2201发送信息至第一类型端口2202的链路出现故障，则第一类型端口2202的物理层生成本地故障信息，可选地，通信设备通过第一端口获得第一类型故障信息的情况下，且确定获得的第一类型故障信息满足第一预设条件，则发送客户服务类型本地故障信息。相对应的，若通信设备2102通过第一类型端口2202获得第一类型故障信息不满足第一预设条件，则可以发送故障清除信息。
进一步，第一类型端口2202发出的客户服务类型本地故障信息沿着第二类型端口2203、第二类型端口2204、第二类型端口2205、第二类型端口2206透传至通信设备2104。由于通信设备2104需要将第二类型端口2206传输的信息通过第一类型端口2207传输出去，因此通信设备2104根据获得的客户服务类型本地故障信息，确定获得的客户服务类型本地故障信息满足第二预设条件，则生成本地故障信息，并将本地故障信息通过第一类型端口2207传输至通信设备2105的第三类型端口2208。可选地，可以是通信设备2104中的故障信息处理模块根据获得的客户服务类型本地故障信息，生成本地故障信息。相对应的，若通信设备2102生成第一类型端口2202对应的故障清除信息，则故障清除信息也可以沿着第二类型端口2203、第二类型端口2204、第二类型端口2205、第二类型端口2206透传至通信设备2104，通信设备2104在确定收到故障清除信息的情况下停止通过第一类型端口2207发送本地故障信息。
进一步，通信设备2105通过第三类型端口2208获得本地故障信息后，可以在确定获得的本地故障信息满足第一预设条件的情况下，第三类型端口2208中的RS下发远端故障信息，可以是持续下发远端故障信息。相对应的，若通信设备2105确定获得的本地故障信息不满足第一预设条件，则不再下发远端故障信息。
进一步，可选地，通信设备2104的第一类型端口2207在收到远端故障信息之后，确定收到的远端故障信息满足第一预设条件，通信设备2104生成客户服务类型远端故障信息并通过第二类型端口2206发送。相应地，若通信设备2105确定收到的远端故障信息不满足第一预设条件，则可以不发送远端故障信息或者发送故障清除信息。
进一步，可选地，通信设备2104通过第二类型端口2206发送的客户服务类型远端故障信息沿着第二类型端口2205、第二类型端口2204、第二类型端口2203一直透传至通信设备2102。由于通信设备2102需要将第二类型端口2203获得的信息通过第一类型端口2202传输出去，因此通信设备2104根据在收到客户服务类型远端故障信息的情况下，且确定收到的客户服务类型远端故障信息满足第二预设条件，通过第一类型端口2202发送远端故障信息。相对应的，若生成第一类型端口2207对应的故障清除信息，则故障清除信息也可以沿着第二类型端口2205、第二类型端口2204、第二类型端口2203一直透传至通信设备2102，通信设备2102在确定收到故障清除信息的情况下停止发送远端故障信息或者发送故障清除信息给通信设备2101的第三类型端口2201。
基于图9所示的***架构，若通信设备2104中配置有保护倒换功能，若第二类型端口之间的链路出现故障，比如第二类型端口2205向第二类型端口2206发送信息的链路出现故障，则通信设备2104中的第二类型端口2206生成本地故障信息，通信设备2104启动第二类型端口2206对应的备用链路，比如启动图9中第二类型端口2301和第二类型端口2302实现通信设备2103和通信设备2104之间的连接。可见，如此，由于本申请实施例中可以将标准以太网协议链路的故障和灵活以太网协议的链路的故障区分，因此即保留了标准以太网协议下的故障协商机制，也可基于保护倒换功能实现灵活以太网协议内部的自愈功能。
本申请实施例中，上述图4中的第二类型端口对应的备用链路可以包括通信设备2103与通信设备2104之间的第二类型端口2301和第二类型端口2303之间的链路，还可以包括通信设备2102的第二类型端口3301和通信设备2103的第二类型端口3302之间的链路，比如启用通信设备2102中第一类型端口2202和第二类型端口3301的关联关系，启用通信设备2103中第二类型端口3302和第二类型端口2301的关联关系，启用通信设备2104中第二类型端口2302和第一类型端口2207的关联关系。也就是说灵活以太网协议内部包括的备用链路可以替换良好以太网协议内部所有的工作链路，从而保证灵活以太网协议内部的自愈功能，比如图4中可以用“第一类型端口2202、第二类型端口3301、第二类型端口3302、第二类型端口2301、第二类型端口2302、第一类型端口2207之间的链路”替换“第一类型端口2202、第二类型端口2203、第二类型端口2204、第二类型端口2205、第二类型端口2206、第一类型端口2207之间的链路”。
本申请实施例中发送第二类型故障信息可以是发送至少两个第二类型故障信息，其中至少两个第二类型故障信息中的任两个第二类型故障信息之间间隔至少一个码块。可选地，根据第一故障信息，通过第二端口发送第二故障信息，包括：根据第一故障信息，通过第二端口发送至少两个第二故障信息；其中，至少一个第二故障信息中的任两个第二故 障信息之间间隔至少一个码块。如此，可以节省灵活以太网协议对应的链路的传输路径的带宽。
本申请实施例中图10示例性示出了本申请实施例提供的一种0x4B的66 bit block码块的示意图，如图10所示，0x4B码块的控制块格式(英文可以称为control block format)为O 0D 1D 2D 3Z 4Z 5Z 6Z 7；同步头(英文也可称为synchronization header)为“10”；块类型区域(英文可以称为block type field)为0x4B；之后的三个字节分别为D1字节、D2字节和D3字节，在D3字节后为O码区域；最后28个比特为0x0000000。0x4B码块是标准以太网IEEE 802.3-2015标准文档图Figure 82-5中定义的一类控制码块。
上述示例中故障清除信息可以是指示客户侧正常的操作管理维护功能(Operation,Administration and Maintenance，OAM)消息块，OAM消息块还可以包括网络中的误码检测、故障侦测、时延测量、路径发现等机制。故障清除信息的OAM消息块可以承载在0x4B码块上。图11示例性示出了本申请实施例提供的一种基于图10所示0x4B码块的故障清除信息的示意图，当通信设备检测到如图10所示的消息块的情况下，具体来说，当通信设备检测到“10”同步头+第一个字节“0x4B”+第四个字节的前4个比特“0x06”+第二个字节和第三个字节的内容“0b00000101”“0b00000000”，则认为收到了故障清除信息。
图12示例性示出了本申请实施例提供的一种基于图10所示0x4B码块的本地故障信息的示意图，图13示例性示出了本申请实施例提供的一种基于图10所示0x4B码块的远端故障信息的示意图。如图12所示，本地故障信息中，同步头为“10”，块类型区域为0x4B；D1字节为0x00、D2字节为0x00；D3字节为0x01，在D3字节后为O码区域为0x0；最后28个比特为0x0000000。如图13所示，远端故障信息中，同步头为“10”，块类型区域为0x4B；D1字节为0x00、D2字节为0x00；D3字节为0x02，在D3字节后为O码区域为0x0；最后28个比特为0x0000000。通过图12和图13可以看出，本地故障信息和远端故障信息通过D3字节进行区分。
本申请实施例中的第二类型故障信息可以用0x4B码块来承载。可选地，第二类型故障信息可以是OAM消息块。图14示例性示出了本申请实施例提供的一种基于图10所示0x4B码块的第二类型故障信息的示意图，如图14所示，第二类型故障信息携带0x4B控制类型“0x4B”和O码区域的“0x6”，使用D1、D2字节承载特定消息块。如图14所示，使用D1字节的前六位作为OAM消息类型字段，当D1字节中的第0至第5比特为“0b000001”可以表示该0x4B码块承载第二类型故障信息，也可以称第二类型故障信息为客户服务信息(Client Service，CS)；使用D1字节的后2位(D1字节的第6至第7比特)和D2字节的前两位比特(D2字节的第0至第1比特)表示CSF、RCSF以及正常情况下承载业务(比如以太网服务，应为可以称为Ethernet service)的信息。举个例子，比如D1字节的第6至第7比特和D2字节的第0至第1比特为“1110”，则表示该0x4B码块承载RCSF；比如D1字节的第6至第7比特和D2字节的第0至第1比特为“1111”，则表示该0x4B码块承载CSF；比如D1字节的第6至第7比特和D2字节的第0至第1比特为“0100”，则表示该0x4B码块承载正常的业务信息(比如以太网服务业务信息)，也可以指示故障清除。也就是说，D1字节的第6至第7比特和D2字节的第0至第1比特为“0100”，可以表示该0x4B码块承载故障清除信息。
图15示例性示出了本申请实施例提供的一种基于图10所示0x4B码块的客户服务类 型本地故障信息的示意图，图16示例性示出了本申请实施例提供的一种基于图10所示0x4B码块的客户服务类型远端故障信息的示意图。如图15所示，客户服务类型本地故障信息中，同步头为“10”，块类型区域为0x4B；D1字节为0b00000111、D2字节为0b11000000；D3字节为0x06，在D3字节后为O码区域为0x6；最后28个比特为0x0000000。如图16所示，客户服务类型远端故障信息中，同步头为“10”，块类型区域为0x4B；D1字节为0b00000111、D2字节为0b10000000；D3字节为0x06，在D3字节后为O码区域为0x6；；最后28个比特为0x0000000。通过图14和图15可以看出，客户服务类型本地故障信息和客户服务类型远端故障信息的O码区域为0x6，而图12和图13所示的本地故障信息和远端故障信息的O码区域为0x0。
基于以上实施例以及相同构思，图17为本申请实施例提供的一种通信设备的示意图，如图17所示，该通信设备4101可以为网络设备，也可以为芯片或电路，比如可设置于网络设备的芯片或电路。该通信设备可以实现如上图7和/或图8中所示的任一项或任多项对应的方法中通信设备所执行的步骤。该通信设备4101可以包括故障信息处理模块4201和至少两个端口。比如该通信设备4101可以包括故障信息处理模块4201和至少一个第一类型端口和至少一个第二类型端口，比如可以是包括第一端口4102和第二端口4103。再比如，该通信设备4101可以包括故障信息处理模块4201和至少两个第一类型端口，比如可以是包括第六端口4107和第七端口4108。再比如，该通信设备4101可以包括故障信息处理模块4201和至少两个第二类型端口，比如可以是包括第三端口4104和第七端口4105。

本申请实施例中故障信息处理模块4201可以是分布式的，各个端口对应设置一个，如上述图2所示，集成在各个端口上，比如故障信息处理模块4201包括图2中的第一类型端口1401中的故障信息处理模块1601、第一类型端口1402中的故障信息处理模块1602和第一类型端口1403中的故障信息处理模块1603。或者本申请实施例中故障信息处理模块4201可以是集中式的，各个端口共用一个，也就是说故障信息处理模块4201可以独立出来，并与各个端口相连接。故障信息处理模块可以设置在第一类型端口的一侧，或者设置在第二类型端口的一侧，图中仅示出了设置在第一类型端口的一侧的示意。故障信息处理模块4201若设置在第一类型端口一侧，可以设置在各个端口物理层以上；若设置在第二类型端口一侧，可以设置在各个端口物理层以上，或者设置在各个端口灵活以太网协议层以上。
本申请实施例中通信设备4101还包括交换单元4301，可选地该交换单元4301可以是上述图2中的交换单元1701，用于存储各个端口之间的关联关系，并可以更新各个端口之间的关联关系等等。相关介绍可以参见前述关于交换单元1701的介绍，在此不再赘述。可选地，图17所示的实施例中，第一端口4102和第二端口4103之间有关联关系，第六端口4107和第七端口4108之间有关联关系，第三端口4104和第四端口4105之间有关联关系。可选地，各个端口之间的关联关系可以是预配置的，该关联关系可以更新，比如根据用户输入的新的关联关系更新，或者根据内部的一些自愈机制的策略进行更新(比如上述内容中启用备用链路所带来的关联关系的更新)等等。
在一种可能的设计中，本申请实施例中第一端口4102，用于获得第一故障信息，比如可以是接收到其它端口发送的第一故障信息或者是第一端口4102的物理层生成的第一故障信息；故障信息处理模块4201，根据第一故障信息，生成第二故障信息；第二端口4103，用于发送第二故障信息；其中，第一端口4102为第一类型端口，第一类型端口根据标准以太网协议传输信息；第一故障信息为第一类型故障信息，第一类型故障信息包括本地故障信息和远端故障信息中的至少一项；第二端口4103为第二类型端口，第二类型端口根据灵活以太网协议传输信息；第二故障信息为第二类型故障信息，第二类型故障信息用于指示标准以太网协议对应的链路发生故障。
本申请实施例中通过第一端口获得第一故障信息，根据第一故障信息，通过第二端口发送第二故障信息，其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息，第一故障信息为第一类型故障信息，第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息，且由于第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，第二故障信息为第二类型故障信息，第二类型故障信息用于指示标准以太网协议对应的链路发生故障，因此通过传输第二故障信息的方式既可以在标准以太网协议和灵活以太网协议联合组网中通报故障，也可以为区分灵活以太网协议对应的链路发生故障和标准以太网协议对应的链路发生故障奠定基础。
在一种可能的设计中，故障信息处理模块4201，用于若获得的第一类型故障信息满足 第一预设条件，则根据第一故障信息，生成第二故障信息；其中，第一预设条件包括：在第一预设时长内获得的第一类型故障信息的数量大于第一数量阈值；或者；获得数量不少于第一数量阈值的第一预设码块，且获得的任两个相邻的第一预设码块之间间隔不超过第一预设码块间隔。如此，可以避免因为数量较少的故障信息导致的误操作，进一步提高操作的准确性。
基于上述内容以及相同构思，本申请实施例还提供一种通信设备，在一种可能的设计中，该通信设备中的第二端口4103，用于获得第三故障信息；其中，第三故障信息为第二类型故障信息；故障信息处理模块4201，还用于根据第三故障信息，生成第四故障信息；其中，第四故障信息为第一类型故障信息；第一端口4102，还用于发送第四故障信息。其中，第一端口为第一类型端口，第一类型端口根据标准以太网协议传输信息，第二端口为第二类型端口，第二类型端口根据灵活以太网协议传输信息。第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，第二类型故障信息用于指示标准以太网协议对应的链路发生故障。
本申请实施例中通过第二端口获得第三故障信息，根据第三故障信息，通过第一端口发送第四故障信息，由于第一类型故障信息包括本地故障信息和远端故障信息中的至少一项，第二类型故障信息用于指示标准以太网协议对应的链路发生故障，因此通过传输第二故障信息的方式既可以在标准以太网协议和灵活以太网协议联合组网中通报故障，也可以为区分灵活以太网协议对应的链路发生故障和标准以太网协议对应的链路发生故障奠定基础；第三也可以兼容标准以太网协议网络中通过第一类型故障信息传输通报故障的方案。
在一种可能的设计中，故障信息处理模块4201，用于若获得的第二类型故障信息满足第二预设条件，则根据第三故障信息，生成第四故障信息；其中，第二预设条件包括在第二预设时长内获得的第三故障信息的数量大于第二数量阈值；或者；获得数量不少于第二数量阈值的第二预设码块，且获得的任两个相邻的第二预设码块之间间隔不超过第二预设码块间隔。如此，可以避免因为数量较少的故障信息导致的误操作，进一步提高操作的准确性。
基于上述所描述，通信设备4101在执行上述图7和/或图8所示的通信方法的实施例中还可能存在其它可能的实施方式，下面介绍通信设备4101在执行上述图7和/或图8所示的通信方法中的其它的可选地实施方式。
在一种可能的设计中，通信设备4101还包括第三端口4104，用于获得第五故障信息；其中，第三端口4104为第二类型端口，第五故障信息为第一类型故障信息或者第二类型故障信息；还包括第四端口4105，用于发送第五故障信息；其中，第四端口4105为第二类型端口。如此，在灵活以太网网络内部可以透传第一类型故障信息和第二类型故障信息，进而可以在灵活以太网网络内部传输第二类型故障信息，在灵活以以太网网络外部传输第一类型故障信息，从而可以根据故障信息的类型区分灵活以太网协议对应的链路发生故障还是标准以太网协议对应的链路发生故障。
在一种可能的设计中，通信设备4101还包括第五端口4106，用于获得第六故障信息；其中，第五端口4106为第二类型端口，第六故障信息为第一类型故障信息；第五端口4106配置备用链路；启用第五端口4106对应的备用链路。可见，本申请实施例中可以实现将标准以太网协议对应的链路发生故障和灵活以太网协议对应的链路发生故障的情况通过 第一类型故障信息和第二类型故障信息进行区分，从而避免标准以太网协议对应的链路发生故障触发保护倒换功能的情况；而且可以更加准确的根据灵活以太网协议网络内部的故障信息触发保护倒换功能。
在一种可能的设计中，第二端口4103，用于发送至少两个第二故障信息；其中，至少一个第二故障信息中的任两个第二故障信息之间间隔至少一个码块。如此，可以灵活设置第二故障信息的发送频率，比如将第二故障信息的发送频率设置的小于第一故障信息的发送频率，则可以节省灵活以太网协议对应的链路的传输路径的带宽。举个例子，比如第一故障信息为远端故障信息，第二故障信息为客户服务类型远端故障信息，远端故障信息为持续发送，占用带宽较大，设置间隔一定数量的码块发送一个客户服务类型远端故障信息，则可以节省带宽。
需要说明的是，本申请实施例中对单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。在本申请的实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
