METHOD FOR TRANSMITTING DATA PACKAGES ON THE BASIS OF VIRTUAL LOCAL NETWORK AND THE BRIDGE DEVICE OF THE ETHERNET NETWORK

摘要

1. A method for transmitting data packets based on a virtual local area network, comprising the steps of: storing a fixed port corresponding to a virtual local area network according to a data packet received by an Ethernet bridge device, and maintaining correspondence between the virtual local area network and the stored fixed port; and forwarding the data packet by the Ethernet bridge device according to the stored correspondence between the virtual local network and the fixed port. ! 2. The method according to claim 1, characterized in that the step of storing the fixed port corresponding to the virtual local area network and maintaining the correspondence between the virtual local network and the fixed port comprises: determining an input port of an Ethernet bridge device for receiving a data packet and determining a virtual local identifier Networks in the data packet and determining, by the bridge device of the Ethernet network, the correspondence between the identifier of the virtual local network and the fixed port according to the input port and the identifier of the virtual local network in the data packet, and storing said correspondence. ! 3. The method according to claim 2, characterized in that the step of determining the correspondence between the identifier of the virtual local area network and the fixed port and storing the specified correspondence comprises maintaining by the bridge device of the Ethernet network the correspondence between the identifier of the virtual local network in the data packet and the input port in case of mismatch of any of records in saved correspondence between virtual LAN identifiers and fixed ports with virtual identifier
