Embodiment Construction

[0039] In order to solve the problems existing in the prior art, the present invention provides a message forwarding method and device, which can enable the AP in the MESH network to first judge whether the data message carries label forwarding information when receiving a data message, and if so, then When the destination forwarding label is not the label of this AP, search for the destination AP corresponding to the destination forwarding label, and forward the message to the destination AP; when the destination forwarding label is the label of this AP, remove all According to the label forwarding information of the message, look up the MAC address entry according to the destination MAC address of the message and forward it; if not, then judge whether the outgoing interface of the data message is a MESHLINK port; Add label forwarding information to the text and forward it to the next-hop AP; if not, forward it according to the MAC address entry. Therefore, in the message for...

Abstract

The invention provides a message forwarding method and apparatus. The method comprises the following steps that firstly, when an AP in the MESH network receives a data message, it first judges whether the data message carries tag forwarding information, If so, the destination AP corresponding to the destination forwarding tag is searched when a destination forwarding tag is not the tag of the AP, and the message is forwarded to the destination AP; when the destination forwarding tag is the tag of the AP, the tag forwarding information of the message is removed, and the MAC address table entry is searched and forwarded according to the destination MAC address of the message; if not, whether the outcoming interface of the data message is the MESHLINK port or not is determined; if yes, the message is added with the tag forwarding information and then forwarded to a next-hop AP; and if not, forwarding is performed according to the MAC address table entry. Therefore, the present invention can prevent each hop AP from guiding the forwarding by looking up the MAC forwarding table entry.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message forwarding method and device. Background technique [0002] In the packet forwarding process in the current wireless mesh (MESH) network, there are often multiple APs (Access Points, Access Points) between the AC (Access Controller, Access Controller) and the terminal device, and each The jumping APs will search for MAC (Media Access Control, media access control address) forwarding entries according to the destination address. When the number of MAC entries increases, the search becomes a time-consuming task, which also affects the efficiency of forwarding. Contents of the invention [0003] In view of this, the present invention provides a message forwarding method and device to solve the problem of low AP forwarding efficiency in MESH networking in the prior art. [0004] Specifically, the present invention is achieved through the following technica...
