Method and network equipment for realizing isolated multi-user virtual local area network

Abstract

The invention discloses a method and network equipment for isolating a multi-user virtual local area network. The method comprises the following steps that: first network equipment receives the data which is sent from a user; the first network equipment determines the number of virtual local area networks (VLAN) according to the VLAN MASK value of the set virtual local area network identification range; the first network equipment encapsulates the data into an ether head so as to obtain the ether message, and the ether head carries the VLAN MASK value and the number of the VLAN; the first network equipment configures VLAN identifications for users according to the number of the VLAN; and the first network equipment sends the ether message to second network equipment, and the ether message carries the corresponding VLAN identifications of the users. According to the method for isolating the multi-user virtual local area network, the VLAN range can be flexibly defined in accordance with the practical requirements so as to satisfy the isolation of multiple users.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a method and network equipment for realizing the isolation of a multi-user virtual local area network. Background technique [0002] The advent of the cloud computing era has changed the traditional IT office methods, as well as the existing enterprise IT information networking methods. In the era of cloud computing, there will be many large-scale public clouds. These super-large clouds can provide rental services for many small and medium-sized enterprises or individual users. Small and medium-sized enterprises can rent the network resources of public clouds to complete their own IT information construction. It will greatly reduce the cost of IT for SME networks, and this model will be the main way for SMEs to use IT in the future. But to meet this business model, one of the problems is that many users need to be served in the same network...

AI Technical Summary

Problems solved by technology

[0003] Existing multi-user isolation schemes are realized through virtual local area network (Virtual Local Area Network, hereinafter referred to as: VLAN) in the two-layer network. Different users are isolated by providing different VLANs for each user. The scope of VLAN The maximum is 4094, so a data center network can only be used by 4094 users at most, which cannot meet the needs of a large number of users
