Detailed Description
The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.
Example one
In order to reflect the relationship between the upper link and the lower link more, in the embodiment of the invention, the lower link which bears the upper link and provides service for the upper link is used as the service layer link; and taking the upper link which uses the lower link and realizes the function of the link of the layer through the lower link as the application link. The method for associating upper and lower links provided in this embodiment is shown in fig. 1, and includes:
And 102, recording all service layer links providing services for the application layer links, and storing the link numbers of the service layer links into a service layer link set field.
In the manner provided by this embodiment, the flooding message is extended, and a special field is added to record the application layer link related information. The format of the expanded flooding message is shown in table 1:
TABLE 1
The application layer link number field, the application layer link other attribute information field, and the service layer link set field shown in table 1 are extended fields, and the information recorded in these three fields may be collectively referred to as application layer link related information.
Wherein, the application layer link number field records the link number of the generated application layer link, and the service layer link set field records the link numbers of all service layer links providing service for the generated application layer link. Through these extended fields, the association between the application layer link and the service layer link is simply implemented on the sending node side.
Example two
Before generating the application layer link, that is, before the step 101, the method for associating between upper and lower layers provided in this embodiment, as shown in fig. 2, further includes:
In this embodiment, the flooding message is extended, and a special field is added to record the service layer link related information. The format of the expanded flooding message is shown in table 2:
TABLE 2
The service layer link number field and the service layer link other attribute information field shown in table 2 are extended fields, and the information recorded in these two fields may be collectively referred to as service layer link related information. Wherein the service layer link number field records the link number of the generated service layer link.
After the service layer link is generated and the flooding of the relevant information of the service layer link is completed, the application layer link may be generated and the above step 101 and 103 are executed, which is not described herein again.
The first and second embodiments described above mainly describe the association between the upper and lower links from the aspect of the sending node, that is, the association between the upper and lower links is recorded by adding a special field in the original flooding message.
It should be noted that, to implement the association between the upper and lower links, it is also necessary to ensure that each time a link is generated, the generated corresponding link number is unique across the entire network. A service layer link or an application layer link can be uniquely identified by a link number.
The link number may be generated according to the following rules:
1. when a service layer link or an application layer link is generated, the node IDs at two ends of the link are compared, and one end of the node ID meeting the preset condition is selected (so that the forward link and the reverse link can be ensured to use the same link number).
Here, the preset condition may be: the end with the large node ID is selected or the end with the small node ID is selected, and it is assumed that the end with the large node ID is selected in this embodiment.
2. And respectively selecting preset bytes from the node IP and the node ID at the selected end and combining the bytes to generate the link number.
For example, the middle 2 bytes of the node IP at the selected end and the first 2 bytes of the node ID are taken to form 4 bytes of data, which is used as the link number of the link, so that the uniqueness of the whole network can be ensured.
Of course, the link number is not limited to the above node information and the selected byte, as long as the formed link number is guaranteed to be unique in the whole network.

TABLE 3
Wherein the service layer link number field records the link number of the generated service layer link.
In order to record the association between the service layer link and the application layer link providing the service, a new field needs to be added to the locally recorded service layer link related information: an application layer linkset field. The format of the service layer link related information in the expanded local record is shown in table 4:
TABLE 4
Through the update of the subsequent flow, the application layer link set field records the link codes of all the application layer links provided by the service layer link.
When receiving a flooding message, the receiving node records the service layer link related information in the format shown in table 4 locally.
Example four
After the step 302, the method for associating between upper and lower links provided by this embodiment as shown in fig. 4 further includes:

TABLE 5
Wherein, the application layer link number field records the link number of the generated application layer link, and the service layer link set field records the link numbers of all service layer links providing service for the generated application layer link.
When receiving a flooding message, the receiving node records the relevant information of the application layer link in the flooding message to the local in the format. The association between the application layer link and all the service layer links providing services for the application layer link can be simply realized by adopting the field record mode.
Firstly, reading the link numbers of all service layer links from the service layer link set field of the locally recorded application layer link related information (refer to table 5);
secondly, according to the read link numbers of all the service layer links, the link numbers of the matched service layer links (the matching is the same) are sequentially searched in the service layer link fields (refer to table 4) of all the service layer link related information stored locally;
finally, the link number of the application layer link is read from the application layer link number field of the locally recorded application layer link related information (refer to table 5), and the read link number of the application layer link is sequentially added to the application layer link set field of the service layer link related information where the link number of the matched service layer link is located (refer to table 4).
The third embodiment and the fourth embodiment describe the association manner between the upper layer link and the lower layer link mainly from the aspect of the receiving node, that is, the association between the upper layer link and the lower layer link is recorded through the fields of the locally stored application layer link related information and service layer link related information.
The association method between the upper layer link and the lower layer link provided in the first to the fourth embodiments of the present invention is based on the existing flooding mechanism, and only adds a special field in the original flooding message to record the association between the application layer link and all the service layer links providing services for the application layer link; based on the received flooding message, the association between the service layer link and all the application links of the services provided by the service layer link can be recorded only by adding special fields in the local storage, so that no additional flooding mechanism is needed, no special table is needed, no special and complete mapping relation needs to be maintained, and the association between the application layer link and the service layer link can be simply realized.
