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 present invention provides a message forwarding method and device, so that when an AP in a MESH network receives a data message, it first judges whether the data message carries label forwarding information, and if so, when the destination forwarding label is not the label of the AP , find 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 the label forwarding information of the message, according to the The destination MAC address of the message is searched for the MAC address entry for forwarding; if not, it is judged whether the outbound interface of the data message is a MESHLINK port; if yes, the label forwarding information is added to the message and forwarded to the next Hop to AP; if not, forward according to MAC address entry. Therefore, the present invention can prevent each hop AP from performing guidance and forwarding by looking up MAC forwarding table items.

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...
