Problems solved by technology

[0004] However, in practical applications, if the server is attacked, after receiving the multicast query message from the Bonjour gateway, the server will send a large number of response messages to the Bonjour gateway. Judgment, only each response message can be processed, which will easily cause the AC where the Bonjour gateway is located to be paralyzed

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0048] In order to solve the problems in the prior art, the embodiments of the present invention provide a message processing method and device, which are applied to an access controller, and a Bonjour gateway is configured in the access controller AC (Access Controller). A packet processing method provided by an embodiment of the present invention will first be described in detail below.

Abstract

The embodiment of the invention discloses a message processing method and device. The method comprises: an access controller multicast is configured to provide query message of a server required by a client and receive a query response message fed back by the server required by the client; when the number of the query response messages fed back by the server in a preset time exceeds a preset threshold value, the query response messages are cached, and a first detection message is sent to the server, if the first detection response message fed back by the server is received, it is determined that the server is not attacked, the cached query response messages are normally processed; and if the first detection response message fed back by the server is not received, it is determined that the server is attacked, the cached query response message is deleted. Therefore, the condition that the device is paralyzed caused by processing lots of response messages through the access controller when the server is attacked.

Description

technical field [0001] The present invention relates to the technical field of wireless networks, in particular to a message processing method and device. Background technique [0002] The Bonjour protocol, also known as the zero-configuration networking protocol, can automatically discover services on the IP network. The Bonjour protocol only defines how to use multicast domain name (mDNS) protocol packets to propagate service information within a VLAN. If mDNS protocol packets need to be forwarded across VLANs, a forwarding device called a Bonjour gateway must be deployed in the network. [0003] In a wireless network scenario, the Bonjour gateway is configured on the access controller AC. After the Bonjour gateway receives the query message multicast by the client to query the server that can provide the service required by the client, it first queries the local Whether there is a server in the service resource list that can provide the service required by the client: if...
