Embodiment Construction

[0010] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0011] As a specific example, such as figure 1 As shown, a VLAN service division network includes an Internet service VLAN network and an internal service VLAN network. The Internet service VLAN network is connected to a VLAN access switch 2 by an access terminal 1, and the VLAN access switch 2 is connected to a core switch 3. The core switch 3 distributes DHCP, and routes to the egress gateway 4 to connect to the Internet 5; the internal service VLAN network is connected to the access switch 7 by the internal access terminal 6, and the access switch 7 is connected to the aggregation switch 8, and the aggregation switch 8 is connected to the core The switch 9 is assigned DHCP by the core switch 9, and the core switch 9 is connected to the service server 10.

[0012] The core switch 3 and the core switch 7 may be the same switch hardware or two switc...

Abstract

The invention relates to the field of internet technologies, and particularly relates to a VLAN (virtual local area network) service division network. The VLAN service division network comprises an Internet service VLAN network and an internal service VLAN network, wherein the Internet service VLAN network is connected to a VLAN access switch by an access terminal, the VLAN access switch is connected to a first core switch, the first core switch distributes a DHCP (dynamic host configuration protocol), and is routed to an outlet gateway and connected to the Internet; the internal service VLAN network is connected to the access switch through an internal access terminal, the access switch is connected to a convergence switch, the convergence switch is connected to a second core switch, the DHCP is distributed by the second core switch, and the second core switch is connected to a service server. According to the invention, DHCP addresses are distributed by the core switches, thereby ensuring the safety of service division and reasonable distribution of flow.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a VLAN service division network. Background technique [0002] With the development of Internet informatization, the application of VLAN services has become more and more extensive. In order to ensure service security, it is necessary to connect different terminals to different systems at the access layer and ensure physical isolation on the access side. The division of existing VLAN services provides service identification and user group division through VLAN IDs, but its security performance and user groups still cause conflicts in service traffic at the egress gateway. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a VLAN service division network, by terminating the service VLAN at the core switch, and assigning DHCP addresses by the core switch, to ensure the security of service division a...
