Example Embodiment

[0035] The core idea of ​​the present invention constructs the routing information of all MPs in the MESH network through the MESH point notification message, so as to avoid the routing request for the MP route and reduce the transmission delay.

[0036] The present invention provides a route maintenance method between MESH points, which is applied to a network including multiple MESH points. The method is shown in FIG. 2 and includes the following steps:

[0037] In step s201, the MESH point broadcasts a notification message to other MESH points at regular intervals or in real time, and the notification message includes the source MESH point address and routing information. The routing information specifically includes: source MESH point address information, destination serial number DSN, hop count and cumulative cost value.

[0038] Step s202, the MESH point receiving the notification message determines the optimal route with the source MESH point according to the routing in...

Abstract

The invention provides a route maintenance method between the MESH points, which is applied in the network including the multiple MESH points, this method includes the following steps: the MESH point broadcasts the notification message to other MESH points which includes the source MESH point address and route information; the MESH points receiving the notification messages determines the optimized route with the MESH point according to the route information. The invention also provides route maintenance system and MESH point between the MESH points. Based on the HWMP protocol, the invention also provides one simple and effective MESH point route learning method, drives and maintains the route learning of the MESH points via the MP ANOUNCEMENT information, so it avoids the route request response process in the HWMP protocol and reduces the transfer delay of the packet.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method and equipment for maintaining routes between MESH points in a MESH (wireless mesh network). Background technique [0002] WLAN (Wireless Local Access Network, wireless local area network) provides a wireless connection service of a local area network. Because it can provide high-speed wireless data access, WLAN is one of the more popular technologies in the IT industry at present, and it is also a popular wireless access method. The WLAN generally adopts a centralized AC (Access Controller, wireless controller)-AP (Access Point, wireless access point) architecture. The AC provides centralized management of the WLAN network, and the AP establishes a link with the AC to join the WLAN network and provide wireless access services. [0003] The centralized WLAN architecture is clearly defined in the CAPWAP (Control and Provisioning of Wireless Access Points) protoc...
