Problems solved by technology

However, the SVL method also has a disadvantage that is difficult to overcome: in the multicast mode, the forwarding table entries of the same purpose have different forwarding destination ports in different VLANs, so the application of the multicast mode is limited.
Therefore, the application of this IVL method produces two problems: one is the problem of bandwidth waste of network equipment, all messages are broadcasting, without taking advantage of the switch; the second is the problem of network security, a user The message can be received by other users, security cannot be guaranteed

Embodiment Construction

[0057] The content of the present invention has been described above, and the specific implementation manner of the present invention will be further described by taking PVLAN as an example. In the IVL (independent VLAN learning) mode, the hosts in the Secondary VLAN of PVAN and the servers in the Primary VLAN do not share the MAC addresses, so they can only exchange information with each other through broadcasting. A large number of broadcasting in the network Packets will inevitably affect the performance of the network obviously. For this reason, the problem that the present invention needs to solve is to realize the sharing of MAC address between Secondary VLAN and Primary VLAN under IVL mode, promptly guarantees that same MAC address exists in Secondary VLAN and Primary VLAN simultaneously, that is to say the MAC address of a user When the address is added to the default VLAN of the port, it must be added to other VLANs that need to share the MAC address. We can call the ...

Abstract

The method includes steps: when adding or deleting access addresses in independent virtual local area network (VLAN), meanwhile operation for adding or deleting access addresses is carried out in address table of defaul VLAN of access address and address table of sharing the access address. The invention prevents lots of broudcast message from occurring on network so as to save limited communication network resources or provide more bandwidth resources for users. Moreover, the invention raises efficiency for searching MAC address table under IVL mode.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing address synchronization in an independent VLAN (virtual local area network) learning mode. Background technique [0002] In network communication, in order to facilitate the management of the communication network and ensure the security of network communication, it is usually necessary to isolate the application of network access devices such as Ethernet switches. A VLAN ID (virtual local area network identifier), and the communication between users in this VLAN and the outside world needs to be realized through the network access device. However, with the increasing development of network communication and the increasing size of network networking, more and more VLAN IDs are required for networking, and the VLAN ID resources that can be allocated are limited. Therefore, when the network scale is large, The number of VLAN IDs that can be pro...
