Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] like figure 1 As shown, the embodiment of the present invention proposes a kind of message forwarding method for Layer 2 Ethernet, comprising the following steps:

[0026] Step S102, the switching device adds the MAC address pre-allocated to the user equipment and the information of the user equipment to the forwarding table of the switching device;

[0027] Step S104, the switching device sends the MAC address pre-allocated to the user equipment to the user equipment;

[0028] Step S106, the switching device receives the message;

[0029] Step S108, the switching device judges whether the source MAC address of the message is the MAC address previously allocated by the switching device to the user equipment, and if so, searches the forwarding table to forward the message.

[0030] Preferably, the switching device assigning ...

Abstract

The invention provides a message forwarding method, a message forwarding system and a switching equipment, which are used for a double-layer Ethernet. The method includes that the switching equipment adds the MAC addresses distributed for user apparatuses and the information of the user apparatuses into the forwarding table of the switching equipment in advance; the switching equipment transmits the MAC addresses distributed for user apparatuses to the user apparatuses; the switching equipment receives messages; the switches judges if the source MAC addresses of the messages are the MAC addresses distributed for the user apparatuses in advance, and searches the forwarding table to forward the messages if the source MAC addresses of the messages are the MAC addresses distributed for the user apparatuses in advance. The technical proposal of the invention guarantees the security of the Ethernet and the controllability of the users when the messages are forwarded.

Description

technical field [0001] The invention relates to the field of Ethernet communication, in particular to a message forwarding method, system and switching equipment for Layer 2 Ethernet. Background technique [0002] With the rapid development of the Internet, the Ethernet network has gradually become an indispensable tool in people's daily work and life. As an essential device to form an Ethernet network, the number of Ethernet switching devices in the network is increasing day by day. With the increase in the number of Ethernet switching devices, various man-made or non-man-made attacks make the Ethernet Layer 2 switching devices prone to problems, affecting people's use of the network. At the same time, the number of Layer 2 Ethernet Layer 2 switching devices is huge , The networking is complex, which makes it quite complicated to locate when a problem occurs. Therefore, the security, stability and ease of maintenance of the network have become the focus of attention. [...
