Detailed Description
The routing system, method and apparatus provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.
The terms "first" and "second" and the like in the description and drawings of the present application are used for distinguishing different objects or for distinguishing different processes for the same object, and are not used for describing a specific order of the objects.
Furthermore, the terms "including" and "having," and any variations thereof, as referred to in the description of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.
In the prior art, a point-to-point private line can be established between two user nodes to realize communication between the two user nodes. Referring to fig. 1, an existing routing system is provided that establishes a peer-to-peer private line between a user site a and a user site B.
As shown in fig. 1, the point-to-point private line may be initiated by a routing device of a user node a, passes through a conversion device of the user node a, passes through a conversion device of a user node B from a transmission network to an opposite end, and finally reaches a routing device of the user node B, so that communication between the user node a and the user node B may be implemented.

That is, the first link is configured as a primary link, the second link is configured as a secondary link, and the default first routing device 01 and the second routing device 04 communicate using the first link, and may switch to the second link when the first link fails.

In summary of the above description, in the routing system provided in the embodiment of the present application, two communication links (corresponding to the first link and the second link in the embodiment of the present application) are established between the first routing device and the second routing device. In the first link, the first conversion device and the second conversion device are respectively connected with the first transmission network subsystem in a wired manner (for example, connected by an optical cable); in the second link, the first gateway device and the second gateway device are wirelessly connected to the second transport network subsystem, respectively. Because the two communication links are respectively in wired connection and wireless connection, when the wired connection fails, the first routing device and the second routing device can realize wireless communication through the second link, and when the wireless network fails, the first routing device and the second routing device can realize wired communication through the first link. Therefore, the routing system provided by the embodiment of the present application can ensure communication between the first routing device and the second routing device, so as to ensure service communication between the user node where the first routing device is located and the user node where the second routing device is located.
