Problems solved by technology

The disadvantage of the existing technology is that this table needs to be maintained by a separate mechanism, including a notification mechanism and a storage mechanism. For example, this correspondence needs to be notified to each member in the topology through flooding or other methods; each Members need to maintain one or more database tables to store this correspondence, so the implementation is very complicated

Embodiment 1

[0059] In order to better reflect the relationship between the upper and lower links, the embodiment of the present invention uses the lower link that bears the upper link and provides services for the upper link as the service layer link; The upper layer link that realizes the link function of this layer is used as the application layer link. The association method between the upper and lower layer links provided by this embodiment is as follows: figure 1 shown, including:

[0060] In step 101, a corresponding link number is generated when an application layer link is generated, and the link number of the application layer link is stored in an application layer link number field.

[0061] Step 102: Record all service layer links providing services for the application layer link, and store the link number of the service layer link in the service layer link set field.

[0062] Step 103: Flood the application layer link related information to the whole network through a flood ...

Embodiment 2

[0069] Before the application layer link is generated, that is, before the above step 101, the method for associating between the upper and lower layer links provided by this embodiment is as follows: figure 2 shown, also includes:

[0070] Step 201: Generate a service layer link providing services for the application layer link and generate a corresponding link number, and store the link number of the service layer link in the service layer link number field.

[0071] Step 202: Flood service layer link related information to the entire network through a flood message, where the service layer link related information includes the service layer link number field.

[0072] In this embodiment, the flood message is extended, and a special field is added to record information related to the service layer link. The format of the extended flood message is shown in Table 2:

[0073]

[0074] Table 2

[0075] The service layer link number field and other attribute information fi...

Embodiment 3

[0086] Corresponding to the flooding message of the service layer link sent by the sending node in the second embodiment, the association method between the upper and lower layer links is as follows: image 3 shown, also includes:

[0087] Step 301: Receive a flooding message of a service layer link, and locally record information related to the service layer link carried in the flooding message.

[0088] Corresponding to Embodiment 2, the service layer link related information recorded locally here includes the service layer link number field and other attribute information fields of the service layer link, and the format shown in Table 3 can be adopted:

[0089]

[0090] table 3

[0091] Wherein, the service layer link number field records the link number of the generated service layer link.

[0092] Step 302: Add an application layer link set field to the locally recorded service layer link related information.

[0093] In order to be able to record the association be...

Abstract

The invention discloses an association method between the upper and lower links. The lower link that bears the upper link and provides services for the upper link is a service layer link. The upper layer link of the layer link function is an application layer link, and the method also includes: generating a corresponding link number when generating the application layer link, and storing the link number of the application layer link in the application layer link In the road number field; record all service layer links that provide services for the application layer link, store the link number of the service layer link in the service layer link set field; pass the flood message to the application layer The link related information is flooded to the whole network, and the application layer link related information includes the application layer link number field and the service layer link set field. The invention discloses an association device and system between upper and lower layers of links.

Description

technical field [0001] The present invention relates to the communication field, in particular to an association method, device and system between upper and lower layers of links. Background technique [0002] In the field of communication, the link that transmits signals often has a layered concept, there are lower-layer links, and upper-layer links based on the lower-layer links. A lower-layer link can serve multiple upper-layer links at the same time, and an upper-layer link can also contain multiple lower-layer links at the same time. There is a many-to-many relationship between upper and lower-layer links. This correspondence is often used. For example, when you need to know which lower-layer links a certain upper-layer link contains, you need to query the correspondence between the upper-layer and upper-layer links; when you need to know which upper-layer links a certain lower-layer link serves, you also need to To query the correspondence between the upper and lower ...
