Problems solved by technology

[0005] After analysis, the inventor found that the routing selection strategies that have been applied so far are basically aimed at the access side, and the business form is single; and the routing selection strategy is generally to select the corresponding route for each type of business, based on the needs of the single business , such as the number of hops, delay, bandwidth, etc., without considering the QoS requirements after the convergence of multiple services
On the other hand, the source node must maintain at least one path for each type of business, which brings a lot of overhead to the route finding and maintenance process, so it has poor scalability for the network and is not suitable for actual Mesh networking

Embodiment Construction

[0017] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, in the embodiment of the present invention, the route selection processing flow of the wireless mesh network backhaul network is as follows:

[0019] Step 101. Determine the service quality QoS requirement values ​​of different types of services of the source node after convergence.

[0020] Step 102, determine the support capability value of the QoS demand value of different links connected to the external network from the source node.

[0021] Step 103: Compare the support capability values, and select a route for the source node to connect to the external network according to the comparison result.

[0022] In the embodiment of the present invention, the route selection of the backhaul network in the IP+Mesh system is carried out. The service is the result of the convergence of services forwarded by the access sid...

Abstract

The invention discloses a routing selection method for a wireless mesh return network. The method comprises the following steps: determining a QoS (quality of service) requirement value after servicesof different types of a source node are converged; determining supporting capacity values for the QoS requirement value when the source node is connected to different links of an external network; and comparing the supporting capacity values, and selecting routing when the source node is connected to the external network according to a comparison result. Meanwhile, the invention discloses the wireless mesh return network. The wireless mesh return network and the routing selection method thereof can provide QoS assurance for the converged services, avoid data congestion, and save the expensesof routing finding and maintenance processes.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a wireless mesh network backhaul network and a routing selection method thereof. Background technique [0002] As the available radio frequencies of the mobile communication system gradually increase, the radius of the cell shrinks; at the same time, due to the sharp increase in business traffic, the original mobile communication network is overwhelmed. Therefore, the site density of the network needs to be continuously increased, which puts forward higher requirements for the construction of the transmission network. Using mesh network (Mesh) technology for wireless networking is a solution to meet this requirement. Realizing interconnection between access points (Access Point, AP) in a wireless manner can effectively reduce the number of optical fiber access points, thereby reducing the network construction cost of operators. At the same time, the wireless Mesh network ...
