Description
Technical field
The present invention relates to the communications field, relate in particular to the technology of dividing VLAN in the communications field.
Background technology
Virtual LAN VLAN (Virtual Local Area Network), thus be a kind of by with the apparatus logic ground in the local area network (LAN) rather than physically be divided into the emerging technology that the network segment is one by one realized the virtual work group.
VLAN proposes for broadcast issue and the fail safe that solves Ethernet, it has increased the VLAN head on the basis of ethernet frame, with VLAN ID the user is divided into littler working group, the two layers of exchanging visit of user between restriction different operating group, each working group is exactly a VLAN.The benefit of VLAN is to limit broadcasting area, and can form the virtual work group, the dynamic management network.
It is VLAN that vlan technology allows network manager that the local area network (LAN) LAN (Local AreaNetwork) of a physics logically is divided into different broadcast domains, each VLAN comprises one group of computer workstation that same requirements is arranged, and with the LAN that physically forms identical attribute is arranged.But because it is logically rather than physically to divide, so each work station in the same VLAN need not be placed in the same physical space, promptly these work stations not necessarily belong to the same physics LAN network segment.The broadcasting of a VLAN inside and unicast traffic can not be forwarded among other VLAN, even two computers have the same network segment, but they but do not have identical vlan number, their broadcasting stream separately can not transmitted mutually yet, thereby helps to control the fail safe of flow, minimizing equipment investment, simplification network management, raising network.
In the prior art, the technology of multiple division VLAN is arranged,, divide, divide, divide according to the IP multicast according to network layer according to MAC Address as dividing according to port, specific as follows described.
1, divides VLAN according to network equipment port
Utilize the port of switch to divide the member of vlan, as shown in Figure 1, the switch LAN switch with 8 ports with two groups of 8 ports-settings, corresponds respectively to different VLAN.For example, the port one of switch, 3,4,7 are defined and belong to virtual LAN VLAN 1, and the port 2,4,6,8 of this switch is defined and belongs to virtual LAN VLAN 2.
Along with the development of technology, a plurality of different ports that second generation port vlan technology allows to cross over a plurality of switches are divided VLAN, and several ports on the different switches can be formed same virtual net.
Divide network members with switch ports themselves, its layoutprocedure is simple and clear, and can allow the communication between each port, and allows the upgrading of shared network.But this partition mode is limited in virtual net on the fixing switch, and for static dividing according to physical port, is not easy to dynamic management.
2, divide VLAN according to MAC Address
The method of this division VLAN is to divide according to the MAC Address of each main frame, promptly the main frame of each MAC Address is all disposed it and belongs to which group.As shown in Figure 2, switch LAN switch and five users with 8 ports, five users' MAC Address is respectively: MAC1, MAC2, MAC3, MAC4, MAC5, with MAC1, MAC2, user's configuration of MAC3 correspondence belongs to virtual LAN VLAN 1, with MAC4, the user of MAC5 correspondence configuration belongs to virtual LAN VLAN 2.
The great advantage of this division VLAN method is exactly when user's physical location moves, promptly when a switch is changed to other switch, VLAN need not reconfigure, so, can think that this division methods according to MAC Address is based on user's VLAN, when the shortcoming of this method was initialization, all users must be configured, if individual even thousands of the users of hundreds of are arranged, configuration is very tired.And the method for this division also may cause switch to carry out the reduction of efficient, because all may have the member of a lot of VLAN groups at the port of each switch, so just can't limit broadcast packet.In addition, for the user who uses notebook computer, their network interface card may often be changed, and like this, VLAN just must ceaselessly dispose.
3, divide VLAN according to network layer
The method of this division VLAN is to divide according to the network layer address of each main frame or protocol type (if supporting multi-protocols), though this division methods is according to the network address, such as the IP address, it is not a route, has no relation with the route of network layer.
When the advantage of this method is user's physical location change, VLAN under not needing to reconfigure, and can divide VLAN according to protocol type, this is very important concerning network manager, also have, the frame tagging that this method does not need to add is discerned VLAN, can reduce the traffic of network like this.
But it is low that the shortcoming of this method is an efficient, because checking the network layer address of each packet is to need to consume the processing time, general exchanger chip can the automatic inspection network on the Ethernet frame head of packet, but allow chip can check the IP frame head, need higher technology, simultaneously also more time-consuming.
4, divide VLAN according to the IP multicast
The IP multicast in fact also is the definition of a kind of VLAN, think that promptly a multicast group is exactly a VLAN, the method of this division has expanded VLAN to wide area network, therefore this method has greater flexibility, and be easy to expand by router, but this method is not suitable for local area network (LAN), mainly is that efficient is not high.
By foregoing description as can be known, the method for above-mentioned division VLAN all is based on traditional data communication network structure, does not realize dividing the method for VLAN in wireless network.
