相关申请的交叉引用
本公开要求享有2020年09月27日提交的名称为“二层业务状态检测方法、通讯设备和存储介质”的中国专利申请CN202011034818.7的优先权，其全部内容通过引用并入本公开中。
技术领域
本公开涉及通信技术领域，尤其涉及一种二层业务状态检测方法、通讯设备和存储介质。
背景技术
二层业务协议包括以太网的点对点业务协议(Point to Point Protocol over Ethernet PPPOE)和动态主机配置业务协议(Dynamic Host Configuration ProtocolDHCP)等，一般由客户端(CLIENT)与服务端(SERVER)完成协议交互。而CLIENT通常位于通讯设备，具体为PON设备(Passive Optical Network，无源光纤网络设备)的用户网络侧接口(User Network Interface，UNI)，SERVER通常也位于通讯设备，具体位于PON设备的业务网络侧接口(Service Node Interface，SNI)。点对多点网络设备(PON设备)通过UNI实现了多个客户端的汇聚，通过SNI实现与服务端的对接。
由于通讯设备本身不进行二层协议业务的发起或终结，因此在通讯设备上对于业务状态正常与否缺少直接的感知与判断，无法检测及确定故障位置和范围。现有都依赖于CLIENT的报障或上层SERVER的统计告警进行判断，不仅效率低，且导致运维成本较大。

附图中所示的流程图仅是示例说明，不是必须包括所有的内容和操作/步骤，也不是必须按所描述的顺序执行。例如，有的操作/步骤还可以分解、组合或部分合并，因此实际执行的顺序有可能根据实际情况改变。
本公开提供了一种二层业务状态检测方法、基站、调用系统和存储介质。
下面结合附图，对本公开的一些实施方式作详细说明。在不冲突的情况下，下述的发明实施例及发明实施例中的特征可以相互组合。
请参阅图1，图1是本公开提供的一种二层业务状态检测方法的示意流程图。
如图1所示，本实施例提供了一种二层业务状态检测方法，该方法包括如下步骤S110和S120。步骤S110：确定二层业务的会话号对应的会话数量，并根据会话数量确定二层业务的状态是否异常。
二层业务包括PPPOE业务协议和DHCP业务协议，以及其它包含ID字段以唯一定义一个协议完成过程的业务，其中，二层业务为数据链路层。获取二层业务的会话号，通过该会 话号来确定该会话号对应的会话数量，例如，统计该会话号的数量，将统计的数量作为会话数量，将该会话数量与预置阈值进行对比，从而确定二层业务的状态是否异常。
在一示例性实施例中，该二层业务为PPPOE业务协议，PPPOE业务协议有两个不同的阶段：发现阶段和PPP会话阶段。当一个主机想开始一个PPPOE会话，它必须首先进行发现阶段以识别对端的物理地址，如，以太网MAC地址，并建立一个会话号，如，PPPOE SESSION_ID。在发现阶段，基于网络的拓扑，客户端可以发现多个服务器，其中，客户端包括主机，服务器包括接入集中器。发现阶段允许主机发现所有的接入集中器，然后选择一个。当发现阶段成功完成，主机和选择的接入集中器都有了他们在以太网上建立链接控制协议点对点传输协议(POINT TO POINT PROTROL，PPP)连接的信息。直到PPP会话建立，发现阶段一直保持无状态的状态。一旦PPP会话建立，主机和接入集中器都必须为PPP虚接口分配资源。PPPOE帧格式中定义了SESSION_ID域(16比特)，网络顺序无符号的值。该值在给定的PPP会话中为常量，它与源地址、目的地址一起定义了一个PPP会话。当PPPOE重新建立时，该SESSION_ID会重新分配，也即SESSION_ID会唯一定义一次PPPOE会话。
或者，该二层业务协议为DHCP业务协议，DHCP的前身是引导程序协议(Bootstrap Protocol BOOTP)。DHCP本身是一种动态主机IP配置协议，从两个方式上扩充了BOOTP：1)DHCP可使计算机用一个消息获取它所需要的所有配置信息即传送配置信息的协议，2)DHCP允许计算机快速动态的获取IP地址、即动态分配IP地址的机制。DHCP使用BOOTP的报文格式但修改了一些字段的内容和含义，其中“事务ID(Transaction ID)”，是CLIENT设备每次发送DHCP请求报文时选择的随机数用来匹配SERVER的响应报文是对哪个请求报文的响应，CLIENT会丢弃事务ID不匹配的响应报文。当DHCP重启获取IP时，其事务ID也是唯一的，也即事务ID可唯一定义一次DHCP交互过程。
在一示例性实施例中，确定二层业务的会话数数量包括：检测到特定二层业务的协议报文，获取协议报文中的会话号；根据会话号和之前记录的会话号，确定会话号的会话数量。
检测到二层业务的协议报文，提取该协议报文中记录的会话号，将该会话号与之前记录的会话号进行比对，确定该会话号与之前记录的会话号是否一致，若该会话号与之前记录的会话号不一致，则确定该会话号的会话数量，其中，该会话号的数量为有效的会话号数量，例如，PPPOE协议中的非零的会话号，如SessionID＝！0x0000等。记录每一种二层业务的协议报文中的会话号，并记录该会话号的会话数量N。例如，检测到二层业务的协议报文中的会话号为初始化会话号时，设置该会话号的初始化会话数量N为0。当获取到的会话号与之前记录的会话号一致，则确定该会话号的会话数量为N+1。
在一示例性实施例中，当二层业务为PPPOE业务协议时，获取确认分组报文 (PPPoEActive Discovery Session-confirmation，PADS报文)中记录的Session ID。通过访问控制列表(Access Control List，ACL)或其它提报规则识别协议的以太网类型＝0x8863，CODE＝0x65的PADS报文，并根据报文格式识别并记录Session ID。其中，检测PADS报文包括如图2所示，PPPOE业务的发现阶段有包括后述S201至S204四个步骤，当此发现阶段完成后，通信的PPPOE CLIENT(PPPOE客户端)和PPPOE SERVER(PPPOE服务端)获取PPPOE SESSION_ID和以太网地址，PPPOE SESSION_ID和以太网地址一起唯一定义PPPOE会话。S201、PPPOE客户端广播一个PPPOE发起分组报文PPPOE Active Discovery Initiiation(CODE＝0x09，会话ID(SESSION-ID)＝0x0000)，简称PADI报文。S202、一个或多个PPPOE服务端发送PPPOE给予分组报文PPPOE Active Discovery Offer(CODE＝0x07，会话ID(SESSION-ID)＝0x0000)，简称PADO报文。S203、PPPOE客户端发送单播会话请求分组报文PPPOE Active Discovery Request(CODE＝0x19，会话ID(SESSION-ID)＝0x0000)，简称PADR报文。S204、对应的PPPOE服务端发送一个确认分组报文PPPOE Active Discovery Session-confirmation(CODE＝0x65，会话ID(SESSION ID)产生一个唯一的PPPOE会话标识码)，简称PADS报文。
或者，当二层业务为DHCP业务协议时，获取地址确认报文(DHCP Acknowledgement，DHCP ACK报文)中的Transaction ID。通过ACL或其它提报规则识别协议的端口号＝67/68，MESSAGE TYPE＝0x05的地址确认报文，并根据报文格式识别并记录Transaction ID。检测DHCP ACK报文包括如图3所示，DHCP业务请求IP地址的过程包括如下步骤S301至S304。S301、DHCP CLIENT(DHCP客户端)发送DHCP DISCOVER广播包(Message Type＝0x01)在网络中寻找DHCP SERVER(DHCP服务端)，其中，DISCOVER为请求广播包；DHCP客户端发起一次请求时选择一个随机数作为“事务ID(Transaction ID)”，用来标识一次地址请求过程。S302、DHCP服务端向DHCP客户端发送DHCP OFFER单播数据包(Message Type＝0x02)，含IP地址、MAC地址、域名信息以及地址租期。S303、DHCP客户端发送DHCP REQUEST广播包(Message Type＝0x03)，正式向对应的DHCP服务端请求分配已提供的IP地址。S304、DHCP服务器向DHCP客户端发送DHCP ACK报文(Message Type＝0x05)，确认DHCP客户端的请求。DHCP客户端收到此DHCP ACK报文后，才真正获得了IP地址与相关配置信息，在整个DHCP地址请求过程中Transaction ID保持不变。
在一示例性实施例中，根据会话数量确定二层业务的状态是否异常，包括：确定会话号的第一预置阈值；若会话数量大于第一预置阈值，则确定二层业务的状态异常。
预先设置一个阈值，将该阈值确定为会话号对应的第一预置阈值，并将还第一预置阈值与该会话号对应的会话数量进行比对。若该会话数量大于第一预置阈值，则确定该二层业务的状态异常。在一示例性实施例中，该二层业务为PPPOE业务时，获取SESSION ID的会话 数量，将SESSION ID的会话数量与第一预置阈值进行比对，若SESSION ID的会话数量大于第一预置阈值，则确定该PPPOE业务的状态异常。或者，该二层业务为DHCP业务时，获取Transaction ID的会话数量，将该Transaction ID的会话数量与第一预置阈值进行比对，若Transaction ID的会话数量大于第一预置阈值，则确定该DHCP业务的状态异常。
确定会话号的第一预置阈值的方式还包括：获取二层业务的协议报文中影响业务协议交互的参数，该影响业务协议交互的参数包括光网络单元(Optical Network Unit，ONU)状态变化数量、对应业务虚拟局域网(Virtual Local Area Network，VLAN)内MAC地址数量变化等。通过该影响业务协议交互的参数确定该二层业务的会话号对应的第一预置阈值。在一示例性实施例中，通讯设备以物理端口或逻辑端口为单位，其中，该物理端口或逻辑端口包括光线路终端(Optical Line Terminal，OLT)、槽位、无源光纤网络口(Passive Optical Network，PON口)、光网络单元口(Optical Network Unit，ONU口)等。启动第一定时器，在一定周期内根据物理或逻辑端口为单位基于第一预置阈值判断业务是否正常，包括：提取对应接口的当前会话数量，当会话数量小于或等于第一预置阈值时，确定对应接口下业务正常，当会话量大于第一预置阈值时，确定对应接口下业务异常。
当通讯设备的物理端口或逻辑端口为ONU口时，获取第一预置周期内ONU接口下对应平均业务MAC地址变化数与平均ONU状态变化数，通过该平均业务MAC地址变化数与平均ONU状态变化数得到第一预置周期的每个周期对应的阈值A1，将该A1作为ONU口对应的第一预置阈值。例如，在获取到平均业务MAC地址变化数和平均ONU状态变化数时，通过第一阈值计算式：阈值A1＝系数1×(平均业务MAC地址变化数+平均ONU状态变化数)，得到阈值A1，其中，系数1为定量，该系数1为对应接口下MAC地址与ONU数量与其表征的特定协议数之间的比例关系。获取平均业务MAC地址变化数包括，获取第一预置周期的每个周期内ONU接口下MAC地址变化数，根据该每个周期内ONU接口下MAC地址变化数，得到第一预置周期的每个周期的平均业务MAC地址变化数。例如，获取第一预置周期的周期数量和第一预置周期的每个周期内ONU接口下MAC地址变化数，通过平均业务MAC地址变化数计算式：其中平均业务MAC地址变化数＝每个周期内ONU接口下MAC地址变化数×周期数量/提取策略启动时长，其中，周期数量为第一预置周期的周期数量，提取策略启动时长为定量，该提取策略启动时长为在提取策略启动到当前的时间，并是第一预置周期的整数倍。获取平均ONU状态变化数包括，获取第一预置周期的每个周期的ONU状态变化次数，将每个周期的ONU状态变化次数相加，得到第一预置周期的ONU状态变化总次数，根据该第一预置周期的ONU状态变化总次数以及第一预置周期的周期数量，得到平均ONU状态变化次数。例如，获取第一预置周期的ONU状态变化总次数以及第一预置周期的周期数量，通过平均ONU状态变化次数计算式：平均ONU状态变化数＝ONU状态变化总次 数×周期数量/提取策略启动时长，其中，周期数量为第一预置周期的周期数量，提取策略启动时长为定量。当通过ONU口启动第一定时器A1时，在第一定时器A1超时时，提取第一定时器A1中记录的ONU口和ONU索引对应的会话数量。将获取到的会话数量与ONU口对应的阈值A1进行比对，若会话数量小于或等于阈值A1，则确定该ONU口对应的ONU业务正常；若会话数量大于阈值A1，则确定该ONU口对应的ONU业务异常。
或者，通讯设备的物理端口或逻辑端口为PON口，获取第二预置周期内PON口下PON口状态变化次数、ONU状态变化数量、对应业务内MAC地址数量以及ONU在线数量，根据PON口状态变化次数、ONU状态变化数量、对应业务内MAC地址数量以及ONU在线数量，得到第二预置周期的每个周期对应的阈值A2，将该A2作为PON口对应的第一预置阈值。例如，获取PON口状态变化次数、ONU状态变化数量、对应业务内MAC地址数量以及ONU在线数量，根据PON口状态变化次数、ONU状态变化数量、对应业务内MAC地址数量以及ONU在线数量，根据第一预置阈值计算式：阈值A2＝系数2×(PON状态变化次数×ONU在线数量+平均业务MAC地址变化数+平均ONU状态变换数)，其中，系数2为定量，该系数2为对应接口下MAC地址与ONU数量与其表征的特定协议数之间的比例关系。获取平均业务MAC地址变化数包括，获取第二预置周期的每个周期内PON口下MAC地址变化数，根据该每个周期内PON口下MAC地址变化数，得到第二预置周期的每个周期的平均业务MAC地址变化数。例如，获取第二预置周期的周期数量和第二预置周期的每个周期内PON口下MAC地址变化数，通过平均业务MAC地址变化数计算式：其中平均业务MAC地址变化数＝每个周期内PON口下MAC地址变化数×周期数量/提取策略启动时长，其中，周期数量为第二预置周期的周期数量，提取策略启动时长为定量，该提取策略启动时长指在提取策略启动到当前的时间，并是第二预置周期的整数倍。获取平均ONU状态变化数包括，获取第二预置周期的每个周期的ONU状态变化次数，将每个周期的ONU状态变化次数相加，得到第二预置周期的ONU状态变化总次数，根据该第二预置周期的ONU状态变化总次数以及第二预置周期的周期数量，得到平均ONU状态变化次数。
例如，获取第二预置周期的ONU状态变化总次数以及第二预置周期的周期数量，通过平均ONU状态变化次数计算式：平均ONU状态变化数＝ONU状态变化总次数×周期数量/提取策略启动时长，其中，周期数量为第二预置周期的周期数量，提取策略启动时长为定量，该提取策略启动时长指在提取策略启动到当前的时间，并是第二预置周期的整数倍。当通过PON口启动第一定时器A2时，在第一定时器A2超时时，提取第一定时器A2中记录的PON口下的会话数量。将获取到的会话数量与PON口对应的阈值A2进行比对，若会话数量小于或等于阈值A2，则确定该PON口对应的PON业务正常；若会话数量大于阈值A2，则确定该PON口对应的PON业务异常。
或者，通讯设备的物理端口或逻辑端口为PON线卡，获取第三预置周期内PON线卡下所有PON口对应的相关参数的总和为SUM(阈值A2)，其中，各个PON口对应的相关参数不相同，得到第三预置周期的每个周期对应的阈值A3，将该A3作为PON线卡对应的第一预置阈值。例如，获取PON线卡下所有PON口对应的阈值A2以及PON口数量，根据计算式阈值A3＝系数3×SUM(阈值A2)，其中，SUM(阈值A2)为PON线卡下所有PON口对应相关参数的总和，其中，各个PON口对应的相关参数不相同，系数3为定量，该系数3为对应接口下MAC地址与ONU数量与其表征的特定协议数之间的比例关系。当通过PON线卡启动第一定时器A3时，在第一定时器A3超时时，提取第一定时器A3中记录的PON线卡下的会话数量。将获取到的会话数量与PON线卡对应的阈值A3进行比对，若会话数量小于或等于阈值A3，则确定该PON线卡对应的PON线卡业务正常；若会话数量大于阈值A3，则确定该PON线卡对应的PON线卡业务异常。
或者，通讯设备的物理端口或逻辑端口为OLT，获取第三预置周期内所有PON线卡对应相关参数的总和的SUM(阈值A3)，其中，各个PON线卡对应相关参数不同，得到第四预置周期的每个周期对应的阈值A4，将该A4作为OLT对应的第一预置阈值。例如，所有PON线卡对应相关参数的总和的阈值A3以及PON线卡数量，根据计算式阈值A4＝系数4×SUM(阈值A3)，其中系数4为定量，该系数4为对应接口下MAC地址与ONU数量与其表征的特定协议数之间的比例关系。SUM(阈值A3)为各PON线卡对应相关参数的总和，其中，各个PON线卡对应相关参数不同。当通过OLT启动第一定时器A4时，在第一定时器A4超时时，提取第一定时器A4中记录的OLT对应的会话数量。将获取到的会话数量与OLT对应的阈值A4进行比对，若会话数量小于或等于阈值A4，则确定该OLT对应的OLT业务正常；若会话数量大于阈值A4，则确定该OLT对应的OLT业务异常。
步骤S120：若确定二层业务的状态异常，则发送异常警告信息。
若确定该二层业务的状态异常，则发送异常警告信息，其中，该异常警告信息包括文字、图像等。示范例包括该二层业务为PPPOE业务，在确定PPPOE业务的状态异常时，发送包含PPPOE业务的异常警告信息，或者，该二层业务为DHCP业务，在确定DHCP业务的状态异常时，发送包含DHCP业务的异常警告信息。或者，PPPOE业务或DHCP业务包括业务涉及的物理端口或逻辑端口，该物理端口或逻辑端口包括OLT，该OLT包括多个PON线卡，该PON线卡包括多个PON，该PON接入多个ONU，当确定ONU业务异常时，发送包含ONU业务的异常警告信息；或者，当确定PON业务异常时，发送包含PON业务的异常警告信息；或者，当确定PON线卡业务异常时，发送包含PON线卡业务的异常警告信息；或者，当确定OLT业务异常时，发送包含OLT业务的异常警告信息。

步骤S420：根据协议交互信息和会话数量，确定二层业务的状态异常类型。
当获取到协议交互信息时，根据获取到的协议交互信息和会话数量，确定PPPOE业务协议或DHCP业务协议的状态异常类型。例如，当协议交互信息中的协议交互协议起始消息个数与会话数的差值大于第二预置阈值，确定PPPOE业务协议或DHCP业务协议涉及的物理或逻辑端口对该协议业务的承载转发有问题；或者，当协议交互协议起始消息个数与会话数的差值小于等于第二阈值，确定PPPOE业务协议或DHCP业务协议涉及的物理或逻辑端口对该协议业务承载正常，异常类型是物理或逻辑端口以外的模块处理或或物理端口/逻辑端口对应的终端、链路或外设备导致的。
在一示例性实施例中，协议交互信息包括协议交互起始协议消息个数，根据协议交互信息和会话数量，确定二层业务的状态异常类型，包括：确定协议交互起始协议消息个数与会话数量之间的差异值，以及确定二层业务的第二预置阈值；若差异值大于第二预置阈值，则确定该物理或逻辑端口承载的二层业务的状态异常类型为业务交互异常；若差异值小于或等于第二预置阈值，则确定该物理或逻辑端口承载的二层业务交互正常，业务异常类型为该物理端口或逻辑端口相关的软硬件转发模块或物理端口/逻辑端口对应的终端、链路或外设备异常导致。

或者，当PON业务异常时，通过PON口第二启用定时器B2，通过该第二定时器B2确定第二预置阈值B2。通过PON口记录的协议交互信息中的协议交互起始协议消息个数，确定协议交互起始协议消息个数与会话数量之间的差异值。将该差异值与第二预置阈值B2进行比对，若该差异值小于或等于第二预置阈值B2，则确定该PON业务异常的类型为业务交互异常，确定该PON业务存在消息交互失败原因导致的业务交互异常。若该差异值大于第二预置阈值B2，则确定该PON业务正常，并确定该PON口对应的ONU终端或链路异常。
或者，当PON线卡业务异常时，通过PON线卡第二启用定时器B3，通过该第二定时器B3确定第二预置阈值B3。通过PON线卡记录的协议交互信息中的协议交互起始协议消息个数，确定协议交互起始协议消息个数与会话数量之间的差异值。将该差异值与第二预置阈值B3进行比对，若该差异值小于或等于第二预置阈值B3，则确定该PON线卡业务异常的类型为业务交互异常，确定该PON线卡业务存在消息交互失败原因导致的业务交互异常。若该差异值大于第二预置阈值B3，则确定该PON线卡业务正常，并确定该PON线卡对应的存在共性的转发模块异常。
或者，当OLT业务异常时，通过OLT第二启用定时器B4，通过该第二定时器B4确定第二预置阈值B4。通过OLT记录的协议交互信息中的协议交互起始协议消息个数，确定协议交互起始协议消息个数与会话数量之间的差异值。将该差异值与第二预置阈值B4进行比对，若该差异值小于或等于第二预置阈值B4，则确定该OLT业务异常的类型为业务交互异常，确定该OLT业务存在消息交互失败原因导致的业务交互异常。若该差异值大于第二预置阈值B4，则确定该OLT业务正常，并确定该OLT对应的外设备异常。
在一示例性实施例中，业务交互异常包括报文异常丢包，报文异常丢包包括上行报文异常丢包和下行报文异常丢包；确定二层业务的状态异常类型为业务交互异常，包括：获取协 议交互信息中相邻的上行报文数量和下行报文数量；根据上行报文数量和下行报文数量，确定二层业务的报文异常丢包是上行报文异常丢包，还是下行报文异常丢包。
在一示例性实施例中，获取协议交互信息中相邻的上行报文信息和下行报文信息，根据获取到的上行报文信息和下行报文信息，确定该二层业务的业务交互异常是否为报文异常丢失。在获取到相邻的上行报文信息中的上行报文数量和下行报文信息中的下行报文数量，通过比对上行报文数量和下行报文数量，确定是上行报文异常丢包还是下行报文异常丢包。其中，上行报文数量为协议交互信息相邻的上行报文个数，下行报文数量为协议交互信息相邻的下行报文个数。例如，分别比较PPPOE协议交互报文中的PADI与PADO报文个数差，PADO报文与PADR报文个数差，PADR报文与PADS报文个数差，判断找出差值最大的一组报文，且该组报文中PADI或PADR报文数量较少，则判断上行报文丢包；该组报文中PADO或PADS报文数量较少，则判断为下行报文丢包。
或者，分别比较DHCP协议交互报文中的DCHP DISCOVERY与DCHP OFFER报文个数差，DHCP OFFER与DHCP REQUEST报文个数差，DHCP REQUEST与DHCP ACK报文个数差，判断找出差值最大的一组报文，且该组报文中DCHP DISCOVERY或DCHP REQUEST报文较少，则判断上行报文丢包；该组报文中DCHP OFFER或DHCP ACK报文较少，则判断下行报文丢包。
当确定是ONU业务异常的业务交互异常时，获取ONU口对应的协议交互信息中相邻的上行报文数量和下行报文数量，将上行报文数量与下行报文数量进行比对。若下行报文数量大于上行报文数量，则判断为ONU上行报文异常丢包；上行消息数量大于下行报文数量，则判断为ONU下行报文异常丢包。
或者，当确定是PON业务异常的业务交互异常时，获取PON口对应的协议交互信息中相邻的上行报文数量和下行报文数量，将上行报文数量与下行报文数量进行比对。若下行报文数量大于上行报文数量，则判断为PON上行报文异常丢包；上行消息数量大于下行报文数量，则判断为PON下行报文异常丢包。
或者，当确定是PON线卡业务异常的业务交互异常时，获取PON线卡对应的协议交互信息中相邻的上行报文数量和下行报文数量，将上行报文数量与下行报文数量进行比对。若下行报文数量大于上行报文数量，则判断为PON线卡上行报文异常丢包；上行消息数量大于下行报文数量，则判断为PON线卡下行报文异常丢包。
或者，当确定是OLT业务异常的业务交互异常时，获取OLT对应的协议交互信息中相邻的上行报文数量和下行报文数量，将上行报文数量与下行报文数量进行比对。若下行报文数量大于上行报文数量，则判断为OLT上行报文异常丢包；上行消息数量大于下行报文数量， 则判断为OLT下行报文异常丢包。
