Embodiment Construction

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0038] see figure 1 , the protocol message in the preferred embodiment of the present invention has three message formats in the entire network: a notification message, a response message and a traceback message. Wherein, the notification message is responsible for notifying the client to stop sending the message. The response message is a message returned to the server after receiving the notification message. It is responsible for notifying the server of the detailed information of the client. When the response message passes through the first switch, the switch itself will add the detailed information of the switch. After detecting the information that already exists in the switch, it will be forwarded directly. The backtracking message is a me...

Abstract

The invention discloses a method and system for detecting and solving a local area network attack. The method comprises the following steps: a server intercepts an MAC address of a client that manufactures a large number of messages, writes the MAC address in a notification message and sends the notification message; after the client receives the notification message, an alert box pops up to prompt a user of the client to stop sending spam messages in the case of MAC matching success, and the client assembles and returns a response messages to the server; after a switch receives the notification message sent by the server, the switch adds the information of the switch, forms a retrospective message and sends back the retrospective messages in a receiving port; and the notification messageis forwarded, a timer is generated at a forwarding port, when the timer is overtime, and if the retrospective message returned by the switch connected with the forwarding port is not received, the forwarding port is closed. The system comprises a server module, a client module and a switch module. By adoption of the method and system disclosed by the invention, the network congestion caused by thespam messages can be cleared.

Description

technical field [0001] The invention relates to the field of network congestion processing, in particular to a method and system for detecting and solving local area network attacks. Background technique [0002] With the rapid development of network communication in our country, the application of Ethernet switch equipment in various small and medium-sized enterprises is becoming more and more extensive. For small and medium businesses, the use of Ethernet switches is essential. Although the current Ethernet switches have more and more functions and are more and more powerful, the high cost also discourages many small and medium-sized enterprises from using some low-end Ethernet switches to save costs. and maintenance time. Cost savings and maintenance time are sometimes not directly proportional. When a certain computer in the company is sending a large number of messages to impact the entire LAN, but the user himself does not know what happened, the company's network r...
