Problems solved by technology

[0005] As can be seen from the above description, in the prior art, when different user hosts access different VLANs, the messages of each user host must be transmitted through different VLANs between the aggregation switch and the gateway device, so that the aggregation switch and the gateway device There are too many VLANs between devices, which greatly wastes VLAN resources
[0006] In addition, since the packets of different user hosts must be transmitted through different VLANs between the aggregation switch and the gateway device, the gateway device must perform VLAN termination processing for different VLANs, which greatly increases the service load of the gateway device In addition, for different VLANs, the gateway device must occupy one of its own routing interface resources, which greatly wastes the interface resources of the gateway device

Embodiment Construction

[0031] The present invention proposes a method for realizing VLAN aggregation, the core idea of ​​which is: setting the corresponding relationship between a plurality of user-side virtual local area network VLANs and a network-side VLAN; After receiving the first message sent by the user host, according to the set corresponding relationship, the first message is sent to the gateway device through the network side VLAN; the aggregation switch receives the second message through the network side VLAN, According to the set corresponding relationship and the destination medium access control (MAC) address carried in the second message, the second message is sent to the corresponding user host through the corresponding user-side VLAN.

[0032] Wherein, setting the corresponding relationship may be realized by setting corresponding access control list (ACL) entries in the aggregation switch.

[0033] Correspondingly, the present invention also proposes an aggregation switch. The ag...

Abstract

The invention discloses a convergence method and exchange to realize VLAN, which comprises the following steps: setting corresponding relationship of different user side VLAN and network side VLAN; receiving the first report from user through user side VLAN for convergence exchange; sending the first report to gateway equipment through user side VLAN according to the set corresponding relationship; accepting the second report through network side VLAN for convergence exchange; sending the second report to corresponding user through user side VLAN according to set corresponding relationship and MAC address with carrying goal in the second report. The invention can proceed report transmission between convergence switch and gateway equipment through the same network side VLAN, which realizes VLAN convergence to save VLAN resource.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for realizing virtual local area network (VLAN) aggregation and an aggregation switch. Background technique [0002] Among many broadband network construction schemes, IP network stands out in the construction of metropolitan area network because of its unique features such as easy operation, simple management and flexible technology, and occupies a large proportion. In the IP network, the three-layer (layer 3, L3) switch is mainly used as the core switching device, and the VLAN is used as the means and method to provide users with high-speed Ethernet dedicated lines to achieve high-speed Internet access or realize their own communication between companies. Data services and other services, such as video on demand and the like. [0003] figure 1 It is a schematic diagram of Layer 2 networking in the prior art. see figure 1 , in the prior art, in Layer 2 networking,...
