本发明涉及通信领域，尤其涉及一种上下层链路之间的关联方法、装置和系统。
在通信领域，传送信号的链路经常有分层的概念，有下层链路，还有基于下层链路的上层链路。一条下层链路可以同时为多条上层链路服务，一条上层链路也可以同时包含多条下层链路，上下层链路之间有多对多的关系，这种对应关系经常被使用到。例如，当需要知道某条上层链路包含了哪些下层链路时，就需要去查询上下层链路之间的对应关系；当需要知道某条下层链路为哪些上层链路服务时，也需要去查询上下层链路之间的对应关系。

下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。
实施例一
为了能更多地体现上下层链路之间的关系，本发明实施例将承载上层链路，为上层链路提供服务的下层链路作为服务层链路；将应用下层链路，通过下层链路实现本层链路功能的上层链路作为应用层链路。该实施例提供的上下层链路之间的关联方法如图1所示，包括：
步骤101，在生成应用层链路时生成相应的链路编号，并将所述应用层
链路的链路编号存储到应用层链路编号字段中。
步骤102，记录为所述应用层链路提供服务的所有服务层链路，将所述服务层链路的链路编号存储到服务层链路集字段中。
步骤103，通过洪泛消息将应用层链路相关信息洪泛到全网，所述应用层链路相关信息包括所述应用层链路编号字段和所述服务层链路集字段。
在该实施例提供的方式中，对洪泛消息进行了扩展，增加了专门的字段用来记录应用层链路相关信息。扩展后的洪泛消息的格式如表1所示：
表1
表1中所示的应用层链路编号字段、应用层链路其他属性信息字段和服务层链路集字段是扩展的字段，这三个字段记录的信息可以统称为应用层链路相关信息。
其中，应用层链路编号字段记录了所生成的应用层链路的链路编号，服务层链路集字段记录了为所生成的应用层链路提供服务的所有服务层链路的链路编号。通过这些扩展的字段，在发送节点侧即简单的实现了应用层链路和服务层链路之间的关联。
实施例二
在生成应用层链路之前、即上述步骤101之前，该实施例提供的上下层链路之间的关联方法，如图2所示，还包括：
步骤201，生成为应用层链路提供服务的服务层链路并生成相应的链路编号，并将所述服务层链路的链路编号存储到服务层链路编号字段中。
步骤202，通过洪泛消息将服务层链路相关信息洪泛到全网，所述服务层链路相关信息包括所述服务层链路编号字段。
在该实施例中，对洪泛消息进行了扩展，增加了专门的字段用来记录服务层链路相关信息。扩展后的洪泛消息的格式如表2所示：
表2
表2中所示的服务层链路编号字段和服务层链路其他属性信息字段是扩展的字段，这两个字段记录的信息可以统称为服务层链路相关信息。其中，服务层链路编号字段记录了所生成的服务层链路的链路编号。
生成服务层链路、并完成服务层链路相关信息的洪泛后，就可以生成应用层链路执行上述步骤101-103，此处不再赘述。
上述实施例一和实施例二主要是从发送节点方面描述了上下层链路之间的关联方式、即通过在原有的洪泛消息中增加专门的字段来记录上下层链路之间的关联。
需要指出的是，要实现上下层链路之间的关联，还需要保证每生成一条链路时，生成的相应链路编号是全网唯一的。通过一个链路编号可以唯一确定一条服务层链路或者一条应用层链路。
链路编号的生成可以依据如下的规则：
1、在生成服务层链路或应用层链路时，比较链路两端的节点ID，选取节点ID满足预设条件的一端(如此，可以保证正反向链路使用同一个链路编号)。
这里，预设条件可以为：选择节点ID大的一端或者选择节点ID小的一端，假设该实施例中选择的是节点ID大的一端。
2、从选取的一端的节点IP和节点ID中分别选取预定的字节并组合，生成所述链路编号。
例如，取所选取一端的节点IP的中间2个字节和节点ID的前2个字节，组成一个4字节的数据，作为该条链路的链路编号，可以保证全网唯
一。
当然，链路编号的组成并不仅限于上述的节点信息及其所选取的字节，只要保证所组成的链路编号是全网唯一即可。
实施例三
对应实施例二中发送节点发出的服务层链路的洪泛消息，上下层链路之间的关联方法如图3所示，还包括：
步骤301，接收服务层链路的洪泛消息，在本地记录所述洪泛消息中携带的服务层链路相关信息。
对应实施例二，此处在本地记录的服务层链路相关信息包括服务层链路编号字段和服务层链路其他属性信息字段，可以采用如表3所示的格式：
表3
其中，服务层链路编号字段记录所述生成的服务层链路的链路编号。
步骤302，在本地记录的所述服务层链路相关信息中增加应用层链路集字段。
为了能够记录服务层链路和其提供服务的应用层链路之间的关联，还需要在本地记录的服务层链路相关信息中增加新的字段：应用层链路集字段。则扩展后的本地记录中服务层链路相关信息的格式如表4所示：
表4
通过后续流程的更新，应用层链路集字段记录了该条服务层链路所提供服务的所有应用层链路的链路编码。
接收节点每接收到一条洪泛消息，在本地都以表4所示的格式记录其中的服务层链路相关信息。
实施例四
在上述步骤302之后，如图4所示该实施例提供的上下层链路之间的关联方法还包括：
步骤401，接收应用层链路的洪泛消息，在本地记录所述洪泛消息中携带的应用层链路相关信息。
对应实施例一，此处在本地记录的应用层链路相关信息包括应用层链路编号字段和服务层链路集字段(还包括应用层链路其他属性信息字段)，可以采用如表5所示的格式：
表5
其中，应用层链路编号字段记录所述生成的应用层链路的链路编号，所述服务层链路集字段记录为所述生成的应用层链路提供服务的所有服务层链路的链路编号。
接收节点每接收到一条洪泛消息时，都将其中的应用层链路相关信息以此种格式记录到本地。采用这种字段记录的方式即可简单地实现应用层链路和为其提供服务的所有服务层链路之间的关联。
步骤402，根据在本地记录的所述应用层链路相关信息更新本地已存储的服务层链路相关信息。
首先，从本地记录的所述应用层链路相关信息的服务层链路集字段中读取所有的服务层链路的链路编号(参照表5)；
其次，根据读取的所有的服务层链路的链路编号，在本地已存储的所
有服务层链路相关信息的服务层链路字段(参照表4)中依次查找到相匹配的服务层链路的链路编号(此处所述相匹配即为相同)；
最后，从本地记录的所述应用层链路相关信息的应用层链路编号字段中读取应用层链路的链路编号(参照表5)，并将所读取的应用层链路的链路编号依次加入所述相匹配的服务层链路的链路编号所在的服务层链路相关信息的应用层链路集字段中(参照表4)。
上述实施例三和实施例四主要是从接收节点方面描述了上下层链路之间的关联方式、即通过在本地存储的应用层链路相关信息和服务层链路相关信息的字段来记录上下层链路之间的关联。
本发明上述实施例一到实施例四所提供的上下层链路之间的关联方法，基于已有的洪泛机制，仅仅在原有的洪泛消息中添加专门字段即可记录应用层链路和为其提供服务的所有服务层链路进行关联；基于接收的洪泛消息，仅仅在本地存储中添加专门的字段即可记录服务层链路和其所提供服务的所有应用链路之间的关联，如此，没有额外的洪泛机制，不需要专门的表格，无需维护一种专门的、完整的映射关系，可以简单地实现应用层链路与服务层链路之间的关联。
实施例五
下面通过一个具体的实施例来说明本发明实施例提供的关联过程，如图5所示，包括：
步骤501，拓扑中新生成了一条节点AB之间的服务层链路，该服务层链路的链路编号为1。通过洪泛，全网各个节点都会获知并在本地记录该服务层链路相关信息，如表6所示：
表6
步骤502，拓扑中新生成了一条节点BC之间的服务层链路，该服务层链路的链路编号为2。通过洪泛，全网各个节点都会获知并在本地记录该服务层链路相关信息，如表7所示：
表7
步骤503，拓扑中新生成了一条节点AC之间的应用层链路，该应用层链路的链路编号为11。
步骤504，记录下为新生成的11号应用层链路提供服务的1号和2号服务层链路的编号，即，将1和2记录到11号链路的服务层链路集字段里。
步骤505，将11号应用层链路相关信息洪泛给全网，通过洪泛，全网各个节点都会获知并在本地记录该应用层链路相关信息，如表8所示：
表8
步骤506，全网的每个节点各自从本地记录的11号应用层链路相关信息中读取到两个服务层链路的链路编号：1和2。
步骤507，各个节点查找本地服务层链路集字段中的链路编号1和2，将链路编号11分别加入链路编号1和2关联的本地应用层链路集字段里。
则每个节点本地保存的服务层链路相关信息更新为表9所示：
表9
其中，表9仅是直观的将一个节点中保存的多条服务层链路相关信息展示出来，在每个节点中，每条服务层链路相关信息都可以是独立存储的，不通过专门的表格将所有的服务层链路相关信息进行整合。
如此，全网每个节点都会获知11号应用层链路经过了1号和2号服务层链路。1号服务层链路为11号应用层链路服务、2号服务层链路为11号应用层链路服务。
