Description

POTN业务处理方法、装置及系统 技术领域
本发明涉及通讯领域，具体地涉及一种光分组传送网(Packet Optical Transport Network，POTN)业务的处理方法、处理装置及处理系统。
背景技术
POTN是融合分组传送技术和光传送技术的一种传送网。它基于统一分组交换平台，可同时支持以太网交换和光传送网(Optical Transport Network，OTN)交换。POTN主要定位在汇聚层和核心层。POTN的演进存在两条路线，一条是基于分组传送网(Packet Transport Network，PTN)增加OTN的功能，而另一条是基于OTN增加PTN的功能。
目前的实现方式主要是基于传统PTN的实现方式，即，只根据标签交换的方式进行业务通讯，从而存在以下缺陷：POTN单板只对标签信息进行校验，而不对OTN时隙信息进行校验。这可能导致POTN单板通过光纤连接可以正常传输业务，但时隙是错乱的，业务并没有真正走在所指定的OTN的时隙上，从而不符合POTN真正融合的意义。
发明内容
本发明实施例提供了一种POTN业务的处理方法、处理装置及处理系统，以解决现有技术只对标签进行校验而不对时隙进行校验，从而导致业务正常传输但时隙错乱的问题。
根据本发明的一个方面，提供一种POTN业务的处理方法，包括：第二节点接收第一节点发送的业务报文以及与所述业务报文对应的标签与时隙信息；在所述第二节点设置有POTN虚接口的情况下，所述第二节点依据与所述POTN虚接口对应的特征信息对所述标签与所述时隙信息分别进行校验，其中，所述POTN虚接口用于传输所述业务报文；以及所述第二节点依据校验结果对所述业务报文进行处理。
根据本发明另一方面，提供了一种POTN业务的处理装置，应用于节点中，包括：接收模块，其构造为接收第一节点发送的业务报文以及与所述业务报文对应的标签与时隙信息；校验模块，在所述节点设置有POTN虚接口的情况下，所述校验模块依据与所述POTN虚接口对应的特征信息对所述标签与所述时隙信息分别进行校验，其中，所述POTN虚接口用于传输所述业务报文；以及处理模块，其构造为依据校验结果对所述业务报文进行处理。
根据本发明的另一方面，提供了一种POTN业务的处理系统，包括第一节点和第二节点，其中，所述第一节点向所述第二节点发送业务报文以及与所述业务报文对应的标签与时隙信息。所述第二节点接收所述业务报文以及与所述业务报文对应的标签与时隙信息，并且在设置有POTN虚接口的情况下，依据与所述POTN虚接口对应的特征信息对所述标签与所述时隙信息分别进行校验，并依据校验结果对所述业务报文进行处理。所述POTN虚接口用于传输所述业务报文。

图2至图7是根据本发明实施例的POTN业务的处理装置框图；
图8是根据本发明实施例的POTN业务的处理系统框图；以及
图9是根据本发明实施例的POTN业务的处理方法流程图。
具体实施方式
下面通过附图和实施例，对本发明的各实施例进一步详细描述。
根据本发明实施例，提供了一种POTN业务的处理方法，通过对标签和时隙分别进行校验，确保了PONT业务能够在对应的标签和时隙下进行传输。
图1是根据本发明实施例的POTN业务的处理方法流程图。
如图1所示，根据本发明实施例的POTN业务的处理方法可以包括步骤S102至S106。
在步骤S102，第二节点接收第一节点发送的业务报文以及与业 务报文对应的标签与时隙信息。
在步骤S104，在第二节点设置有POTN虚接口的情况下，第二节点依据与POTN虚接口对应的特征信息对标签与时隙信息分别进行校验。POTN虚接口用于传输业务报文。
在步骤S106，第二节点依据校验结果对业务报文进行处理。
设置有POTN虚接口的第二节点可以为边缘节点也可以为中间节点。当第二节点为边缘节点时，第二节点必然设置有POTN虚接口。
根据本发明的实施例，第二节点依据与POTN虚接口对应的特征信息对标签与时隙信息分别进行校验的步骤可以包括：第二节点依据与POTN虚接口对应的入标签对与业务报文对应的标签进行校验；以及第二节点依据与POTN虚接口对应的时隙信息对与业务报文对应的时隙信息进行校验。
根据本发明的实施例，第二节点依据校验结果对业务报文进行处理的步骤可以包括：在第二节点为边缘节点且校验结果为校验一致的情况下，第二节点接收业务报文；并且在第二节点为中间节点且校验结果为校验一致的情况下，第二节点将业务报文转发给下一节点。
此外，在校验结果为校验不一致的情况下(即，对标签进行校验的校验结果与对时隙信息进行校验的校验结果二者中有至少一个校验结果为校验不一致)，第二节点可以将业务报文丢弃。
根据本发明的实施例，在第二节点为中间节点且校验结果为校验一致的情况下，第二节点将业务报文转发给下一节点的步骤可以包括：第二节点将与业务报文对应的标签更新为与POTN虚接口对应的出标签，并将出标签以及时隙信息转发给下一节点。
POTN虚接口设置有入标签和出标签两个标签信息。在接收到第一节点发送的标签信息时，第二节点会将接收的标签信息与POTN虚接口对应的入标签进行校验，如果一致，则校验成功。POTN虚接口的时隙是唯一的，因此时隙的校验就是一致性校验。第二节点随后会将接收的业务报文的标签信息更新为与POTN虚接口对应的出标签，并将更新的标签信息转发出去，同时也会将业务报文以及校验成功的时隙信息一起发送出去。
根据本发明的实施例，在第二节点依据与POTN虚接口对应的特征信息对标签与时隙信息进行校验之前，POTN业务的处理方法还可以包括：第二节点选取一个或多个OTN时隙进行绑定，并依据绑定的时隙生成POTN虚接口。
根据本发明的实施例，在第二节点接收第一节点发送的业务报文以及与业务报文对应的标签与时隙信息之后，POTN业务的处理方法还可以包括：在第二节点未设置有POTN虚接口的情况下，第二节点判断预先设置的交叉映射关系是否存储有接收的时隙信息；以及在存储有接收的时隙信息的情况下，第二节点将该业务报文转发给下一节点。
根据本发明的实施例，未设置有POTN虚接口的第二节点只可能是中间节点。因此，当第二节点没有设置标签信息时，只对接收的时隙信息进行校验。时隙信息的校验方式不同于设置有POTN虚接口时的时隙信息的校验方式，是通过预先设置的交叉映射关系对时隙进行校验。
根据本发明的实施例，在第二节点判断预先设移置的交叉映射关系是否存储有接收的时隙信息之后，POTN业务的处理方法还可以包括：在存储有接收的时隙信息的情况下，第二节点依据交叉映射关系对业务报文的时隙信息进行更新，并将更新后的时隙信息以及接收的标签转发给下一节点。
在交叉映射关系中存储了时隙的两两对应关系，如果在交叉映射关系中查找到接收的时隙信息，则第二节点将交叉映射关系中与接收的时隙信息对应的另一时隙信息作为更新后的时隙信息与业务报文以及标签信息一并转发出去。
图2至图7是根据本发明实施例的POTN业务的处理装置框图。
如图2所示，根据本发明实施例的PONT业务的处理装置可以包括接收模块22、校验模块24和处理模块26。
接收模块22构造为接收第一节点发送的业务报文以及与业务报文对应的标签与时隙信息。
在设置有POTN虚接口的情况下，校验模块24依据与POTN虚接 口对应的特征信息对接收的标签与该时隙信息分别进行校验。POTN虚接口用于传输业务报文。
处理模块26构造为依据校验结果对业务报文进行处理。
根据本发明的实施例，校验模块24构造为：依据与POTN虚接口对应的入标签对接收的标签进行校验，并依据与POTN虚接口对应的时隙信息对与业务报文对应的时隙信息进行校验。
如图3所示，处理模块26可以包括接收子模块32、转发子模块34和丢弃子模块36。
在节点为边缘节点且校验结果为校验一致的情况下，接收子模块32接收业务报文。
在节点为中间节点且校验结果为校验一致的情况下，转发子模块34将业务报文转发给下一节点。
在校验结果为校验不一致的情况下，丢弃子模块36将业务报文丢弃。
如图4所示，根据本发明实施例的PONT业务的处理装置还可以包括更新模块42。在节点为中间节点且校验结果为校验一致的情况下，更新模块42将与业务报文对应的标签更新为与POTN虚接口对应的出标签。
如图5所示，根据本发明实施例的PONT业务的处理装置还可以包括生成模块52。生成模块52构造为选取一个或多个OTN时隙进行绑定，并依据绑定的时隙生成该POTN虚接口。
如图6所示，根据本发明实施例的PONT业务的处理装置还可以包括判断模块62和转发模块64。
在节点未设置有POTN虚接口的情况下，判断模块62判断预先设置的交叉映射关系是否存储有接收的时隙信息。
在交叉映射关系中存储有接收的时隙信息的情况下，转发模块64将业务报文转发给下一节点。
如图7所示，根据本发明实施例的PONT业务的处理装置还可以包括第二转发模块72。在交叉映射关系中存储有接收的时隙信息的情况下，第二转发模块72依据该交叉映射关系对该时隙信息进行更 新，并将更新后的时隙信息以及接收的标签转发给下一节点。
图8是根据本发明实施例的POTN业务的处理系统框图。
如图8所示，根据本发明实施例的POTN业务的处理系统可以包括第一节点82和第二节点84。
第一节点82向第二节点84发送业务报文以及与业务报文对应的标签与时隙信息。
第二节点84接收业务报文以及与业务报文对应的标签与时隙信息。在设置有POTN虚接口的情况下，第二节点84依据与POTN虚接口对应的特征信息对接收的标签与该时隙信息分别进行校验。POTN虚接口用于传输业务报文。此外，第二节点84依据校验结果对业务报文进行处理。
本发明的实施例还提供了一种存储介质，其中存储有用于执行以下步骤S1至S3的程序代码。
在步骤S1，第二节点接收第一节点发送的业务报文以及与业务报文对应的标签与时隙信息。
在步骤S2，在第二节点设置有POTN虚接口的情况下，第二节点依据与POTN虚接口对应的特征信息对接收的标签与时隙信息分别进行校验，其中，POTN虚接口用于传输业务报文。
在步骤S3，第二节点依据校验结果对业务报文进行处理。
根据本发明的实施例的存储介质可以包括(但不限于)：U盘、只读存储器(ROM，Read-Only Memory)、随机存取存储器(RAM，Random Access Memory)、移动硬盘、磁碟或者光盘等各种可以存储程序代码的介质。
处理器可以根据存储介质中存储的程序代码执行上述步骤S1、S2以及S3。

图9是根据本发明实施例的POTN业务的处理方法流程图。
如图9所示，根据本发明实施例的POTN业务的处理方法可以包括步骤S901至S911。
在步骤S901，第二节点接收第一节点发送的通用成帧规程(Generic Framing Procedure，GFP)报文和时隙报文，其中，GFP报文中携带有标签信息以及业务报文信息。
在步骤S902，判断第二节点是否设置有传输业务报文的POTN虚接口。在判断结果为“是”的情况下，执行步骤S903，并且在判断结果为“否”的情况下，执行步骤S908。
在步骤S903，解析GFP报文以及时隙报文，并获取标签和时隙信息。
在步骤S904，判断GFP报文携带的标签信息与POTN虚接口对应的入标签是否一致，并且判断时隙报文携带的时隙信息和与POTN虚接口对应的时隙信息是否一致。在两个判断的结果均为“是”的情况下，执行步骤S905，否则执行步骤S911。
在步骤S905，判断第二节点是否为业务报文的目标节点。在判断结果为“是”的情况下，执行步骤S906，并且在判断结果为“否”的情况下，执行步骤S907。
在步骤S906，接收业务报文。
在步骤S907，利用与POTN虚接口对应的出标签对业务报文进行封装生成新的GFP报文，并将新的GFP报文与时隙报文一并转发给下一节点。
在步骤S908，解析时隙报文，并获取时隙信息。
在步骤S909，判断交叉映射关系中是否存储有获取的时隙信息。在判断结果为“是”的情况下，执行步骤S910，并且在判断结果为“否”的情况下，执行步骤S911。
在步骤S910，将时隙报文携带的时隙信息更新为交叉映射关系对应的时隙信息，并重新进行封装以形成新的时隙报文，并且将新的时隙报文与GFP报文一并转发给下一节点。
装置步骤S911，丢弃该业务报文。
通过上述方法，如果所有的校验都成功，就打通从源节点到宿节点(源节点到宿节点即边缘节点)方向的业务流，如果中间有校验失败的，报文丢弃，业务流就不通。反方向的业务流，即从宿节点到源节点方向的业务流，其处理方式与正向的传输方式一样，从而实现双向业务流的传输。
应当注意的是，同一节点可以配置多个POTN虚接口，多个虚接口承载多条业务。对于同一条业务的传输而言，只要承载该业务的虚接口上的特征信息能够匹配即可。其他业务的传输方法与该条业务的传输方法一致。
以上所述仅为本发明的优选实施例，并不用于限制本发明。在本发明的精神和原则之间，通过全部硬件或全部软件来实现，或者所作的任何修改、替换，改进等均应包含在本发明的保护范围之内。
