IETFDetNet工作组提出了指定周期排队转发(Cycle Specified Queuing and Forwarding，CSQF)和大规模确定性网络IP技术(Large-scale Deterministic IP Network，LDN)，不要求全网时间同步，仅要求频率同步，能够为关键业务提供确定性传输服务。
在周期调度转发模型中，控制器在对确定性业务进行端到端路径规划时，需要获取物理链路精确时延，但在实际应用中，光纤会受环境温湿度、载波频率、弯曲度等因素的影响；为了提高链路时延的测量精度，通常选择使用专用的网络光频域反射仪(Optical Frequency Domain Reflectometer，OFDR)等设备来测量光纤物理时延，在光纤路径不发生跳变的情况下，该测量过程不需重复进行。
然而，在发生OTN网络光路发生变化、光模块器件损坏、光纤断裂等情况时，光设备可能自动进行保护倒换，将光信号从一条物理光纤切换到另一条物理光纤上去，即发生光纤链路跳变，如附图4所示。在光纤链路跳变发生时，链路时延可能会发生变化，但此时用户和控制面无法及时获取并响应链路跳变，进而无法保证端到端路径规划的准确性。
针对相关技术中，在链路发生跳变时，无法及时检测到等问题，尚未提供有效的解决方案。

在本实施例中提供了一种运行于上述计算机终端的报文发送方法，图2是根据本公开实施例的报文发送方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，确定第一通信节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量；
需要说明的是，上述周期模板窗口为上游节点(相当于上述第一通信节点)和下游节点(相当于上述第二通信节点)同时支持的周期模板。
需要说明的是，上述位置偏移量可以记为offset，测量得到的offset值保存在下游节点，且offset值的测量精度可达到ns级别。
步骤S204，在所述位置偏移量的变化值大于预设阈值的情况下，发送链路跳变通告报文，其中，所述位置偏移量的变化值为所述位置偏移量与上一次确定的位置偏移值的差值。
需要说明的是，上述预设阈值是根据选用的周期模板计算得到的，若offset值的变化量超过了预设阈值，则认为光纤链路可能发生了跳变，并发出相应的链路跳变通告报文。
通过上述步骤，通过在第一通信节点发送跳变检测报文时，确定第一通信节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量；并在用于指示位置偏移量与上一次确定的位置偏移量的差值的位置偏移量的变化值大于预设阈值的情况下，发送链路跳变通告报文；从而实现在链路发生跳变时，能够及时获取到；因此，可以解决相关技术中，在链路发生跳变时，无法及时检测到的问题，达到能够及时检测到链路跳变的效果。
可选的，执行上述步骤S202：确定第一通信节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量之前，所述方法还包括：接收所述第一通信节点在所述周期模板窗口的开始时刻或结束时刻发送的所述跳变检测报文。

可选的，执行上述步骤S202：确定第一通信节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量之后，所述方法还包括：在所述跳变检测报文为所述第一通信节点发送的第一个跳变检测报文的情况下，保存所述位置偏移量；在所述跳变检测报文不是所述第一通信节点发送的第一个跳变检测报文，且所述位置偏移量的变化值小于或等于所述预设阈值的情况下，将所述位置偏移量与上一次确定的位置偏移值进行比较，以确定所述位置偏移量的变化值。
可选的，发送的所述链路跳变通告报文，包括：用于标识所述第一通信节点的第一字段，用于标识第二通信节点的第二字段，所述周期模板窗口的时隙大小，所述上一次确定的位置偏移值，所述位置偏移量，所述位置偏移量的变化值。
在本实施例中还提供了另一种运行于上述计算机终端的报文发送方法，图3是根据本公开实施例的另一种报文发送方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302：将跳变检测报文发送至第二通信节点，以指示所述第二通信节点确定第一通信节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量，并在所述位置偏移量的变化值大于预设阈值的情况下，发送链路跳变通告报文，其中，所述位置偏移量的变化值为所述位置偏移量与上一次确定的位置偏移值的差值。
通过上述步骤，通过将跳变检测报文发送给第二通信节点指示该第二通信节点确定第一通信节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量，并在该位置偏移量的变化值大于预设阈值的情况下，发送链路跳变通告报文；解决了相关技术中，在链路发生跳变时，无法及时检测到的问题，达到能够及时检测到链路跳变的效果。
可选的，执行上述步骤S302：将跳变检测报文发送至第二通信节点之前，所述方法还包括：确定所述第二通信节点和第一通信节点均支持的多个周期模板；从所述多个周期模板中确定出目标周期模板，并根据所述目标周期模板确定所述跳变检测报文的预设发送间隔，其中，所述预设发送间隔为所述周期模板的时隙长度的整数倍。
可选的，执行上述步骤S302：将跳变检测报文发送至第二通信节点，可以通过以下步骤来实现：在第一通信节点的周期模板窗口的开始时刻或结束时刻发送所述跳变检测报文。
可选的，发送的所述链路跳变通告报文，包括：用于标识第一通信节点的第一字段，用于标识所述第二通信节点的第二字段，所述周期模板窗口的时隙大小，所述上一次确定的位置偏移值，所述位置偏移量，所述位置偏移量的变化值。
以下结合附图5对上述链路跳变检测过程的原理进行描述，图5是根据本公开实施例的一种可选的链路跳变检测原理示意图，如图5所示：
跳变检测报文在到达下游节点时，根据选用的周期模板计算和存储offset值，随着后续检测报文持续到达，下游节点根据offset值的变化情况，设置一个阈值δ，如果offset值的变化量超过δ，则认为光纤链路可能发生了跳变，并发出相应的链路跳变通告报文。可见，图5中offset1和offset2的值小于δ，因此认定没有发生链路跳变，而offset3的值大于δ，因此认定发生了链路跳变。
进一步地，以下结合附图6对链路跳变检测的流程进行说明，图6是根据本公开实施例的一种可选的链路跳变检测的流程图，如图6所示，具体包括如下步骤：
步骤1：激活网络设备的链路跳变检测功能，指定跳变检测报文的发送频率以及选用的周期模板；
需要说明的是，上游节点检测报文的发送频率可由用户灵活指定，特别的由于检测报文需要在窗口的开始或结束时刻发送，因此检测报文的发送间隔必须是时隙长度T的整数倍，例如当T＝20us时，测量报文发送频率可以设置为20us，40us，60us等，本申请对此不作限制。
需要说明的是，如果上下游设备同时支持多个周期模板，则为了提高测量频率，可以选择最小周期模板的窗口为基准发送检测报文，此时需在检测报文中携带选用的周期模板。
步骤2：上游节点按照指定的周期模板构造链路跳变检测报文；
步骤3：下游节点按照指定频率在周期模板窗口的开始时刻发送测量报文；
步骤4：下游节点接收检测报文，如果是第一个检测报文，则计算在指定周期内的偏差值(相当于上述位置偏移量)并保存，跳变差值(相当于上述位置偏移量)置为0，执行步骤7；否则，计算出offset的值并与本地存储的offset值进行比较；
步骤5：如果计算的offset值和本地存储的offset值的偏差值不超过阈值δ，则跳变差值置0，执行步骤7；
需要说明的是，阈值δ的制定与检测精度有关，可以根据实际环境温湿度变化、光纤负载变化、光纤长度等情况综合决定δ的值，δ的值可以是一个绝对值，也可以是一个比例，本申请对此不作限制。
步骤6：更新存储的offset值和跳变差值，发出链路跳变通告报文；
需要说明的是，在下游节点检测到跳变发生时，可选的将链路跳变行为、跳变偏差值通告到上游节点或控制器，然后上游节点或控制器可触发或通知用户重新进行光纤链路时延的测量。具体地，通告的信息，至少要包含能够标识本端网络设备的地址或者接口，能够标识对端网络设备的地址或者接口，周期大小、跳变标记和跳变差值等。本公开对信息通告的方式不做限制，例如可以通过扩展IGP(OSPF、ISIS)、BGP的属性通告到网络其它节点，也可通过扩展南向接口(如NETCONF、BGPCEP、BGP-LS等)上报到控制器。
步骤7：跳变检测结束。
通过上述步骤，在上游节点发送跳变检测报文时，确定上游节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量，在位置偏移量的变化值大于预设阈值的情况下，发送链路跳变通告报文；从而实现在链路发生跳变时，能够及时获取到；因此，可以解决相关技术中，在链路发生跳变时，无法及时检测到的问题，达到能够及时检测到链路跳变的效果。
为了帮助更好地理解技术方案，本申请还提供了以下实施例来对技术方案进行进一步描述。
实施例1
以下结合图7和图8对实施例1的方案进行描述说明，图7是根据本公开实施例的另一种可选的光纤链路跳变的示意图，图8是根据本公开实施例的另一种可选的链路跳变检测的流程图。
如图7所示，在本实施例中，假设有两台网络设备N1和N2，两设备间频率同步但时间不同步，在业务方向N1-＞N2上，A是上游设备节点，N2是下游设备节点，N1和N2设备都支持3个周期模板，分别为A、B、C，周期模板时隙长度分别为10us，20us和40us。在N1中，选择周期模板A的时隙长度作为检测报文发送间隔，即跳变检测报文发送间隔为10us。在N2中，设置跳变检测的阈值δ为500ns。两台设备间的相位差Δ为5us，光纤时延为12us，在N1发出第2个检测报文后，链路跳变，跳变后光纤时延为18us，根据已有技术，前三个检测报文到达N2节点落在窗口内的偏移值offset。
此时跳变检测总的流程如图8所示，包括如下步骤：
步骤1：激活N1和N2节点跳变检测测试功能，报文发送频率为10us，选用周期模板为A模板；
步骤2：N1节点在A模板窗口开始时刻以10us为间隔构造发送检测报文；
步骤3：N2节点收到第1个检测报文，计算得到offset值为7us，存储到本地，跳变差值置0；
步骤4：N2节点收到第2个检测报文，计算得到offset值为7us，计算与存储offset值的偏差，未超过阈值δ＝500ns；
步骤5：N2节点收到第3个检测报文，计算得到offset值为3us，计算与存储offset的偏差值为4us，超过阈值δ＝500ns；
步骤6：更新存储offset值为3us，跳变偏差更新为3us；
步骤7：发出链路跳变通告报文。
通过上述步骤，通过在第一通信节点发送跳变检测报文时，确定第一通信节点发送的跳变检测报文在第二通信节点的周期模板窗口内的位置偏移量；并在用于指示位置偏移量与上一次确定的位置偏移量的差值的位置偏移量的变化值大于预设阈值的情况下，发送链路跳变通告报文；从而实现在链路发生跳变时，能够及时获取到；因此，可以解决相关技术中，在链路发生跳变时，无法及时检测到的问题，达到能够及时检测到链路跳变的效果。
实施例2
以下结合图9对本实施例进行说明，图9是根据本公开实施例的一种可选的链路跳变通告报文的封装格式示意图；
本实施例给出了一种链路跳变信息通告报文的封装示例，例如可以扩展OSPF，新增一种链路属性sub-TLV叫做link-switch sub-TLV，用来携带该链路关联的两台设备之间的链路发生跳变的相关信息，包括链路跳变前后的offset值和跳变偏差offset-deviation，封装示意格式如附图9所示：
其中，type字段用一个特定的数值表示此sub-TLV为链路跳变偏差属性类型，length字段表示该sub-TLV数据部分的长度，值为8，cycle-template字段用来指定选用的周期模板时隙长度大小，例如对周期模板A为10us，字段长度为20ctets；跳变前pre-offset值，占20ctets，跳变后post-offset值占20ctets；跳变前后偏差offset-deviation占20ctets。
对上述扩展的cycle-offset sub-TLV的具体携带位置不做特别限定，可以是链路属性的sub-TLV，也可以是节点属性的sub-TLV，只要包含能够标识本端节点和对端节点的信息，以及相关的链路跳变偏差信息即可。
需要说明的是，本申请实施例只给出了扩展OSPF的示例，其他协议(如IS-IS，BGP-LS) 的扩展也与上述方案相似，本申请对此不再赘述。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台第二节点设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
