具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参见图1，图1是本申请实施例提供的通道资源调整方法的流程图，由通信通道中的第一网元执行，所述通信通道中包括多个网元，如图1所示，该方法包括以下步骤：
步骤101、接收管理控制单元发送的用于指示撤销资源调整的命令。
本申请实施例可应用于对通信通道中的通信设备也即网元在资源调整(如调整带宽、频率、速率等)时出现的异常情况(包括调整未完成、调整失败等)的处理，具体提出了通过对通道中各网元进行管控的管理控制单元，在通道资源出现调整异常情况时，对通道中的网元下发撤销资源调整的命令，来指示网元对本次资源调整执行撤销处理，以使网元保持调整前的资源不变，进而保证端到端通道资源保持匹配状态，避免因通道资源不匹配而出现丢包、传输能力下降等传输故障。
上述通信通道具体可以是指源端到宿端之间的通信传输通道，即一条通信通道可包括依次连接的源端、多个中间网元和宿端，其中，源端是指发送端，宿端是指接收端，当一条通信通道为双向传输通道时，源端和宿端可以互换，即通信通道中的两端既可以作为发送端，也可以作为接收端。
所述通信通道可以是城域传送网(Metro Transport Network，MTN)通道，也可以是非MTN通道。
上述第一网元可以是指通信通道中的任一网元，即可以是源端、中间网元或宿端。
上述管理控制单元可以是指与通信通道中的各网元连接的网络控制单元，用于对所述通信通道中的各网元进行管理控制，包括向各网元下发指令、收集 各网元上报的信息等。所述管理控制单元可以为独立的中心，或者也可以与其他单元合并设置。
本申请实施例中，所述通信通道中的各网元均可以在资源调整的过程中，发现并向所述管理控制单元上报资源调整异常情况，从而所述管理控制单元可以接收到所述通信通道中的某个网元在检测到所述通信通道出现资源调整异常的情况下上报的告警信息，即该告警信息中可以是用于指示当前资源调整存在异常情况的信息，具体地，还可以指示具体是哪个网元出现了异常，例如，是上报所述告警信息的网元出现调整失败，还是上报所述告警信息的网元发现其他网元未完成资源调整。
需说明的是，所述通信通道中的各网元可以基于所述管理控制单元下发的资源调整命令，进行资源调整，并且各网元可以是按照节点位置、资源调整方向(如是调大还是调小)有序地进行资源调整，以保证对所述通信通道进行无损调整。其中，一种具体的实施方式中，所述资源调整可以是带宽调整，包括带宽减小调整或带宽增大调整。
例如，所述管理控制单元可以基于实际需求，向所述通信通道中的各网元下发资源调整命令，并在该命令中携带资源调整配置信息，以指示具体如何调整资源，所述通信通道中的各网元则基于所述资源调整命令，从源节点(即源端)开始向宿节点(即宿端)的方向依次对各个节点进行有序地资源减小调整，或者，从宿节点开始向源节点的方向依次对各个节点进行有序地资源增大调整。
所述通信通道中的任一网元均可以在资源调整的过程中检测是否出现资源调整异常情况，且任一网元检测到资源调整异常情况时，都可以向所述管理控制单元上报告警信息。当所述第一网元检测到资源调整异常情况时，所述第一网元可以向所述管理控制单元上报有关资源调整异常的告警信息，也就是说，所述步骤101之前，所述方法还可包括：
在检测到所述通信通道出现资源调整异常的情况下，向所述管理控制单元发送告警信息。
具体地，所述第一网元可以是检测到自身出现资源调整失败，或者检测到 其相邻网元，如上游网元(向所述第一网元发送信息的网元)或下游网元(接收所述第一网元发送的信息的网元)出现资源调整异常，如资源调整失败或资源调整无响应。
这样，所述第一网元可以及时发现并上报资源调整异常情况。
而当非所述第一网元，即所述通信通道中的其他网元检测到资源调整异常情况时，其他网元也可向所述管理控制单元发送告警信息，所述管理控制单元则可以向所述通信通道中的各个网元下发撤销资源调整的命令，从而所述第一网元作为非上报告警信息的网元，也可以接收到所述管理控制单元发送的用于指示撤销资源调整的命令。
在一些实施例中，所述检测到所述通信通道出现资源调整异常，包括：
向第二网元发送资源调整请求消息，其中，所述第二网元为所述多个网元中与所述第一网元相邻的网元；
在超过预设时长未接收到所述第二网元发送的资源调整回复消息的情况下，检测到所述通信通道出现资源调整异常。
一种实施方式中，可以在所述通信通道中的各网元设立资源调整消息超时响应机制，即如果某一网元的资源调整请求消息发出，对应的资源调整回复消息在设定时间内没有收到，则该网元可以上报告警信息至所述管理控制单元，所述管理控制单元再下发撤销资源调整的命令至所述通信通道中的各网元。
所述通信通道中的各网元可按序进行资源调整，具体地，可按照通道的信号传输方向，由所述通信通道中的上游网元向下游网元发送资源调整请求消息，在正常情况下所述下游网元在接收所述资源调整请求消息后，需向所述下游网元返回资源调整回复消息，而在出现异常情况，如网元设备故障或网络故障等时，所述下游网元可能接收不到所述资源调整请求消息，进而无法向所述第一个网元返回资源调整回复消息，或者所述下游网元无法发出所述资源调整回复消息，还或者所述上游网元无法接收到所述资源调整回复消息，此时所述上游网元可以通过超时响应机制，确定检测到当前所述通信通道出现了资源调整异常情况。其中，所述上游网元和所述下游网元可以是所述通信通道中任意相邻 的两个网元。
该实施方式中，所述第一网元可以作为上游网元向与其相邻的下游网元即第二网元发送资源调整请求消息，并从发送所述资源调整请求消息的时刻起开始计时，具体地，可以设定一个预设时长的定时器，当检测到超过所述预设时长未接收到所述第二网元返回的资源调整回复消息的情况下，可以确定检测到所述通信通道出现资源调整异常的情况，具体为在所述第二网元进行资源调整时出现异常，从而可向所述管理控制单元发送告警信息。而在所述预设时长内接收到所述第二网元返回的资源调整回复消息的情况下，可以确认当前通信通道无异常，所述第二网元可以正常执行资源调整，并可在调整成功后，按序开始下一个网元的资源调整。其中，所述预设时长可以根据实际需求预先设定，例如，可设置为1秒、1.5秒、2秒等。
这样，该实施方式中，可通过消息超时响应机制，来使所述通信通道中的网元及时发现所述通信通道中的资源调整异常情况，并通过上报告警信息来促使所述管理控制单元和所述通信通道中的各网元触发对该异常情况的有效应对机制。
在一些实施例中，所述检测到所述通信通道出现资源调整异常，包括：
向第二网元发送资源调整请求消息，其中，所述第二网元为所述多个网元中与所述第一网元相邻的网元；
在超过预设时长未接收到所述第二网元发送的资源调整回复消息的情况下，向所述第二网元重发资源调整请求消息；
在重发次数达到预设次数，且仍超过所述预设时长未接收到所述第二网元发送的资源调整回复消息的情况下，向所述管理控制单元发送所述告警信息。
即一种更具体的实施方式中，还可以在所述通信通道中的各网元设立资源调整消息超时响应重发机制，即如果某一网元的资源调整请求消息发出，对应的资源调整回复消息在设定时间内没有收到，则该网元可以重发资源调整请求消息，若重发后对应的资源调整回复消息在设定时间内仍没有收到，则上报告警信息至所述管理控制单元；或者，还可以设定最多重发次数m，在重发m次 资源调整请求消息后对应的资源调整回复消息在设定时间内仍没有收到，则上报告警信息至所述管理控制单元；所述管理控制单元再下发撤销资源调整的命令至所述通信通道中的各网元。
该实施方式中，所述第一网元可以作为上游网元向与其相邻的下游网元即第二网元发送资源调整请求消息，并从发送所述资源调整请求消息的时刻起开始计时，具体地，可以设定一个预设时长的定时器，当检测到超过所述预设时长未接收到所述第二网元返回的资源调整回复消息的情况下，可以向所述第二网元重发资源调整请求消息，在重发后仍超过所述预设时长未接收到所述第二网元返回的资源调整回复消息的情况下，可以确定检测到所述通信通道出现资源调整异常的情况，具体为在所述第二网元进行资源调整时出现异常，从而可向所述管理控制单元发送告警信息。
或者，还可预先设定最大重发次数，在超过所述预设时长未接收到所述第二网元返回的资源调整回复消息的情况下，可以每间隔所述预设时长向所述第二网元重发一次资源调整请求消息，直至重发次数达到预设的最大重发次数，并且仍超过所述预设时长未接收到所述第二网元返回的资源调整回复消息的情况下，则可向所述管理控制单元发送告警信息。其中，所述最大重发次数可以根据实际需求预先设定，例如，可设置为2次、3次、4次等。
而在某次重发所述资源调整请求消息后的所述预设时长内接收到所述第二网元返回的资源调整回复消息的情况下，可以确认当前通信通道无异常，所述第二网元可以正常执行资源调整，并可在调整成功后，按序开始下一个网元的资源调整。
这样，该实施方式中，可通过进一步设立消息超时响应重发机制，可以给通道资源调整预留更多的时间和尝试次数，以更好地确保通道资源调整的顺利进行，避免有时由于短暂的网络故障或丢包等情况导致的暂时回复消息超时现象。
下面以MTN通道为例，来说明上述设立消息超时响应和重发的机制的具体实施方式：
1)MTN通道中某一节点(即网元)向下游节点发送时隙请求(Calendar Request，CR)消息后，可设置时隙确认(Calendar Acknowledge，CA)消息响应超时定时器为1s。超时未接收到CA响应则重发CR消息，CR消息最多重发次数为3次。当重发CR消息3次后仍未收到CA响应，则该网元向管理控制单元上报告警信息，管理控制单元则下发撤销时隙调整的命令给端到端MTN通道的各网元。即该方式中，资源调整请求消息为CR消息，对应的资源调整回复消息为CA消息。
2)小颗粒通道时隙带宽增大调整流程中，当通道中某一节点发送切换(Switch，S)消息后，设置收到上游节点的CR消息超时定时器为1s。超时未接收到CR消息则重发S消息，S消息最多重发次数为3次。当重发S消息3次后仍未收到上游节点的CR消息，则该网元向管理控制单元上报告警信息，管理控制单元则下发撤销时隙调整的命令给端到端通道的各网元。即该方式中，资源调整请求消息为S消息，对应的资源调整回复消息为CR消息。
在一些实施例中，所述在检测到所述通信通道出现资源调整异常的情况下，向管理控制单元发送告警信息，包括：
在所述第一网元进行资源调整的过程中出现调整失败的情况下，检测到所述通信通道出现资源调整异常，向所述管理控制单元发送所述告警信息。
另一种实施方式中，可以由所述通信通道中的各网元检测自己的资源调整异常情况，并在检测到时及时向所述管理控制单元上报告警信息。即如果正在执行资源调整的网元检测到自己出现调整失败时，可以由该出现调整失败的网元向所述管理控制单元发送告警信息。
该实施方式中，所述第一网元可以是所述通信通道中的任一网元，即当所述通信通道中任一网元在进行资源调整的过程中出现调整失败的情况时，都可以由该调整失败的网元向所述管理控制单元发送告警信息。
这样，该实施方式中，可通过所述通信通道中的各网元检测自身的资源调整情况，并在检测到调整失败时，及时上报告警信息来促使所述管理控制单元和所述通信通道中的各网元触发对该异常情况的有效应对机制。
其中，所述管理控制单元可以在接收到所述通信通道中任一网元发送的告警信息时，指示所述通信通道中的某特定网元或各个网元撤销资源调整，具体可以是向所述通信通道中的第五网元或各个网元发送用于指示撤销资源调整的命令，其中，所述第五网元可以是上报所述告警信息的网元，也可以是所述告警信息中指示的出现资源调整异常的网元。
即所述管理控制单元可以一次性指示所述通信通道中的所有网元都执行资源调整撤销处理，所述通信通道中的各个网元则可基于各自接收的撤销资源调整的命令，撤销本次资源调整；所述管理控制单元也可以只向特定网元如上报所述告警信息的网元或实际出现资源调整异常的网元(通常为上报所述告警信息的网元，或与上报所述告警信息的网元相邻的上游网元或下游网元)，指示执行资源调整撤销处理，并通过该特定网元依次向上或向下传递的过程，通知其他网元也进行资源调整撤销处理。
步骤102、基于所述命令，对所述第一网元的资源调整进行撤销处理。
所述第一网元在接收到所述撤销资源调整的命令的情况下，可以对所述第一网元的资源调整进行撤销处理，即可保持原有的资源不变。具体地，可分两种不同的情况进行不同方式的撤销处理。
也就是说，所述步骤102可包括：
在所述第一网元已完成资源调整的情况下，执行资源回退处理；
或者，在所述第一网元未完成资源调整的情况下，删除资源调整配置信息。
即对于所述通信通道中已经完成本次资源调整的网元，可以执行资源回退处理，也即回退至本次调整前的资源情况，使所述通信通道中各网元的资源保持原有的匹配状态，避免出现端到端资源不匹配的问题。
而对于所述通信通道中未完成本次资源调整(包括调整失败、还未进行资源调整)的网元，无需进行资源回退处理，而是可以删除本次资源调整配置信息，也即所述管理控制单元在向所述通信通道中各网元下发本次资源调整命令时所携带的资源调整配置信息，以避免所述通信通道中残留不必要的配置信息来占用通信资源。
在一些实施例中，所述步骤102包括：
在所述资源调整为减小带宽，且所述第一网元已完成资源调整的情况下，与第三网元之间执行带宽增大的调整处理，其中，所述第三网元为所述通信通道中于所述第一网元上游的网元；
或者，在所述资源调整为增大带宽，且所述第一网元已完成资源调整的情况下，与第四网元之间执行带宽减小的调整处理，其中，所述第四网元为所述通信通道中于所述第一网元下游的网元。
一种具体的实施方式中，本申请实施例可应用对通道带宽资源进行调整的场景，且可以是对所述通信通道的带宽资源进行减小或增大调整。
其中，在所述资源调整为减小带宽的场景下，上述资源回退处理可以是对于所述通信通道中已完成带宽减小调整的网元，按照带宽减小的调整方向，反向进行增大带宽处理，以将各网元的带宽回退至减小前的带宽。具体地，在所述通信通道中已完成带宽减小调整的网元中的任一网元，如所述第一网元已执行完资源回退处理的情况下，可以与其上游网元即第三网元，执行资源回退处理，即进行带宽增大调整，以实现对已完成带宽减小调整的网元进行依次向上游逐段做增加带宽调整。
需说明的是，在对所述通信通道进行减小带宽调整的流程中，所述通信通道中各网元可按从源节点依次向下游节点的方向进行逐个带宽减小调整，从而在对已执行完带宽减小调整的网元进行回退处理时，对这些网元按照从末节点(最后一个完成资源减小调整的网元)依次向上游节点的反方向进行逐个带宽增大调整。
具体的通道时隙带宽减小调整场景下的资源回退处理的节点流程图可如图4a所示。其中，按信号传输方向，该通道包括源端PE 1、P 1节点、P 2节点、…、P n节点和宿端PE 2，在进行业务带宽减小调整时，首先，源端PE 1向P 1节点发送CR消息，正常情况下，P 1节点收到CR消息后，向其上游节点即源端PE 1返回CA消息，源端PE 1再向P 1节点发送时隙配置(Calendar Configuration，C)消息；P 1节点调小带宽后，向下一节点即P 2节点发送CR消息，正常情况下， P 2节点收到CR消息后，P 2节点向其上游节点即P 1节点返回CA消息；而当通道出现异常情况时，P 1节点可能无法在预定时长内收到P 2节点的CA消息，从而出现CA消息超时响应，P 1节点向管控(即管理控制单元)发送告警信息。此时源端PE 1和P 1节点完成了带宽减小调整，剩余P 2节点至P n，及宿端PE 2未完成带宽减小调整，从而需要从P 1节点开始向上游逐段做带宽增加处理，即依次对P 1节点和源端PE 1进行带宽回退处理，而对于剩余P 2节点至P n和宿端PE 2，则执行删除本次带宽减小调整操作中由管控下发的时隙调整配置信息。
在所述资源调整为增大带宽的场景下，上述资源回退处理可以是对于所述通信通道中已完成带宽增大调整的网元，按照带宽增大的调整方向，反向进行减小带宽处理，以将各网元的带宽回退至增大前的带宽。具体地，在所述通信通道中已完成带宽增大调整的网元中的任一网元，如所述第一网元，已执行完资源回退处理的情况下，可以与其下游网元即第四网元，执行资源回退处理，即进行带宽减小调整，以实现对已完成带宽增大调整的网元进行依次向下游逐段做减小带宽调整。
需说明的是，在对所述通信通道进行增大带宽调整的流程中，所述通信通道中各网元可按从宿节点依次向上游节点的方向进行逐个带宽增大调整，从而在对已执行完带宽增大调整的网元进行回退处理时，对这些网元按照从首节点(最后一个完成资源增大调整的网元)依次向下游节点的反方向进行逐个带宽减小调整。
具体的通道时隙带宽增大调整场景下的资源回退处理的节点流程图可如图4b所示。其中，按信号传输方向，该通道包括源端PE 1、P 1节点、P 2节点、…、P n节点和宿端PE 2，在进行业务带宽增大调整时，首先，宿端PE 2向P n节点发送S消息，正常情况下，P n节点收到S消息后，向其下游节点即宿端PE 2发送CR消息，宿端PE 2收到CR消息后，向其上游节点即P n节点返回CA消息，P n节点再向宿端PE 2发送C消息；并且P n节点向下一节点即P n-1节点发送发送S消息，正常情况下，P n-1节点收到S消息后，向其下游节点即P n节点发送CR消息；而当通道出现异常情况时，P n节点可能无法在预定时长内收到P n-1节点 的CR消息，从而出现CR消息超时响应，P n节点向管控(即管理控制单元)发送告警信息。此时P n节点和宿端PE 2完成了带宽增大调整，剩余节点P n-1至P 1，及源端PE 1未完成带宽增大调整，从而需要从P n节点开始向下游逐段做带宽减小处理，即依次对P n节点和宿端PE 2进行带宽回退处理，而对于剩余节点P n-1至P 1和源端PE 1，则执行删除本次带宽增大调整操作中由管控下发的时隙调整配置信息。
这样，通过该实施方式，可保证在对所述通信通道在进行带宽资源调整时，能够按照资源调整方向，对所述通信通道中各网元按序逐次地进行资源回退处理，实现对所述通信通道的无损调整，保证所述通信通道中端到端的带宽资源匹配。
需说明的是，针对双向通信通道，即通道的两个端网元之间可以互相发送信息和接收信息，两个端网元可以互为发送端和接收端。则在通道时隙资源调整流程(包括带宽调小或调大流程)中，如果两个方向(即发送方向和接收方向)的端到端网元中存在任意一个网元的资源调整执行失败，则需对两个方向均执行资源回退流程，具体可按照上述回退处理方式执行。
本申请实施例提出的端到端通道资源调整回退的方法，能够实现通道资源调整问题的检测，并在检测之后对通道资源进行有序和有效地调整回退，满足技术需求，即保证端到端通道资源匹配。
本申请实施例的通道资源调整方法，通道资源调整方法由通信通道中的第一网元执行，所述通信通道中包括多个网元，该方法包括：接收管理控制单元发送的用于指示撤销资源调整的命令；基于所述命令，对所述第一网元的资源调整进行撤销处理。这样，在通信通道资源调整出现异常情况时，通过由管理控制单元向通信通道中的网元下发指示撤销资源调整的命令，来促使通信通道中的网元撤销本次资源调整，从而可保证通信通道中各网元的资源匹配，避免因通道资源不匹配所带来的传输异常问题。
参见图2，图2是本申请实施例提供的通道资源调整方法的流程图，由管理控制单元执行，所述管理控制单元与通信通道中的多个网元通信连接，如图 2所示，该方法包括以下步骤：
步骤201、接收第一网元在检测到所述通信通道出现资源调整异常的情况下，发送的告警信息，其中，所述第一网元为所述多个网元中的任一网元。
步骤202、向所述多个网元中的第五网元发送用于指示撤销资源调整的命令。
在一些实施例中，所述步骤202包括：
向所述多个网元中的各个网元发送用于指示撤销资源调整的命令。
需说明的是，本实施例作为与图1所示方法实施例中对应的管理控制单元侧的实施方式，其具体的实施方式可以参见前述实施例中的相关描述，为避免重复，此处不再赘述。
