Description

一种管理数据传输通道的方法及装置
本申请要求于2014年12月30日提交中国专利局、申请号为201410842925.0、发明名称为“一种管理数据传输通道的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种管理数据传输通道的方法及装置。
背景技术
目前，随着通信技术的发展，很多数据传输网络中都会采用基于多协议标签交换的传输子集(英文：Multi Protocol Label Switching Transport Profile，简称：MPLS-TP)技术。
MPLS-TP技术的主要功能之一是保持用于承担网络业务的数据传输通道的畅通。MPLS-TP技术中通道保护倒换的机制大致为：源端服务商边缘PE(英文：Provider Edge，简称：PE)路由器和宿端PE路由器(通常源端PE路由器简称为源端PE，宿端PE路由器简称为宿端PE)进行数据交互的过程中，源端PE和宿端PE之间一般会设置有两条传输通道，即工作通道和保护通道，默认状态下源端PE和宿端PE优先采用工作通道进行数据交互，并通过源端PE与宿端PE周期性相互发送连续性监测报文CCM(英文：Continuity Check Message，简称：CCM)，判断工作通道是否出现了连续丢包或误码等情况，若是，则将源端PE和宿端PE所使用的通道由工作通道切换为保护通道。。
然而在很多复杂的业务场景中，影响网络业务的因素并不仅限于连续丢包或误码，还有很多其他因素导致不能及时切换工作通道，比如：传输时延。但是根据现有的CCM的接收情况很难准确判定数据传输是否存在较大时延，因此当存在多种影响网络业务的因素时，目前通道保护倒换的机制难以及时触发工作通道的切换，依然采用传输能力较低的通道承担网络业务，降低了复杂的业务场景中的网络业务的质量。

例如：宿端PE还可以按照预设周期，通过步骤101获取的所述第一通道上所传输的数据在至少两个相邻周期中的时延，并计算出差值，从而得到所述第一通道上所传输的数据的抖动值，检测所述第一通道的抖动值是否大于预设的抖动值门限，若是则所述第一通道上发生故障事件，若否则所述第一通道上未发生故障事件。
103、若所述第一通道上发生所述故障事件，则将所述源端PE和所述宿端PE的工作通道切换至所述第二通道。
若所述第一通道上未发生所述故障事件，则所述源端PE和所述宿端PE的工作通道仍为所述第一通道。
在本发明实施例中，通过步骤102对所述第一通道上是否发生故障事件进行检测，若所述第一通道上发生所述故障事件，则将如图1所示的所述源端PE和所述宿端PE当前的工作通道由所述第一通道切换至所述第二通道；若所述第一通道上未发生所述故障事件，则所述源端PE和所述宿端PE的工作通道不进行切换。本发明实施例提供的一种管理数据传输通道的方法，获取第一通道上所传输的数据的时延和第一通道的连续性参数，之后检测第一通道上是否发生故障事件，若发生故障事件，则将源端PE和宿端PE的工作通道切换至第二通道，其中，通道上发生的故障事件包括以下中的至少一项：通道的连续性参数大于预设的阈值、通道上所传输的数据的时延大于预设的时延门限、通道上所传输的数据的抖动值大于预设的抖动值门限和通道的误码率大于预设的误码率 门限。相比较于现有技术，本发明实施例能够在判定是否发生故障事件的过程中，通过参考通道中的连续丢包情况、时延情况和误码率情况的一种或多种情况，保障了当存在多种影响网络业务的因素时，通道保护倒换的机制可以及时触发工作通道的切换，能及时采用传输能力较高的通道承担网络业务，提高了复杂的业务场景中的网络业务的质量。
在本发明实施例中，所述第一通道上传输至少两项业务的数据，所述第一通道上传输至少第一业务和第二业务的数据；所述第一业务的优先级大于所述第二业务的优先级，其中，业务的优先级与业务对于时延的容忍程度负相关。
所述业务的优先级与业务对于时延的容忍程度负相关，具体体现为：业务的优先级越高，则业务对于时延的容忍程度越低，即业务对于时延的要求越高；业务的优先级越小，则业务对于时延的容忍程度越高，即业务对于时延的要求越低。其中，对于时延敏感性较高的业务，可以称为容忍程度较低的业务；对于时延敏感性较低的业务，可以称为容忍程度较高的业务。

需要说明的是，业务的优先级可以根据具体业务类型从网络上获取，或由技术人员预先设定；在至少两项业务中包括了对于时延要求较高的业务，比如视频业务、语音业务和邮件业务等其他对于时延敏感度较高的业务中的两项；数据的抖动值是根据数据的时延获取的，其中，第一通道上业务的时延可以在获取所述第一通道上所传输的数据的时延之后，从所传输的数据的时延中筛选出业务的时延，也可以从所述第一通道上所传 输的数据中确定业务，从而直接获取该业务的时延。
