Description
Technical field
The present invention relates to data communication field, particularly a kind of transmission method of message and device.
Background technology
SUPERVLAN (super VLAN) cries VLAN (VLAN) polymerization again, this technology is tied up a plurality of sub-interfaces or real interface in a virtual interface, this virtual interface is exactly the SUPERVLAN interface, and each sub-interface or real interface are called the Sub-VLAN of this SUPERVLAN.
SUPERVLAN can dispose three layer interfaces, and Sub-VLAN can not dispose three layer interfaces.
When the user in the Sub-VLAN need carry out three layers of communication, IP (the Internet Protocol of SUPERVLAN three layer interfaces will be used, Internet protocol) address is as gateway address, the shared IP network section of a plurality of like this Sub-VLAN, thus saved the IP address resource.
This technology can make the main frame that adheres to different broadcast domains separately that is in the same physical equipment be in same IPv4 (Internet protocol the 4th edition) subnet, and use same default gateway, so just can eliminate the original restriction that in a VLAN or MAN (Metropolitan Area Network, metropolitan area network), must use a special I P subnet.
Use this mechanism can obviously reduce among VLAN or the MAN consumption, improve the service efficiency of IP address, the not enough problem in buffering IP address IP address space.In addition, also can reduce the difficulty of IP address management in the network.
SUPERVLAN can allow the gateway of different VLAN use same IP.And this IP is exactly the IP of SUPERVLAN, and it is VLAN in logic, and following different VLAN can regard its Sub-VLAN as, and these Sub-VLAN are physics, add that port could activate.As long as there is a Sub-VLAN to activate, SUPERVLAN activates so.
When using SUPERVLAN, SUPERVLAN can define any IP address, but does not have the member port of oneself, and port all is to specify in the Sub-VLAN.Sub-VLAN does not have the IP address of oneself as the member of SUPERVLAN, and is to use the routing interface address of the IP address of SUPERVLAN as oneself.Usually client all is to specify in the Sub-VLAN, and we can selectively distribute some address fields, prerequisite in Sub-VLAN be that these address fields must be in the subnet scoping of SUPERVLAN, so that our better management ip address.
In order to realize three layer intercommunications and Sub-VLAN and other network interworkings between different Sub-VLAN, need utilize ARP (Address Resolution Protocol, address resolution protocol) agent functionality.Can carry out the forwarding and the processing of ARP request and response message by ARP proxy, thereby realize three layer intercommunications between two layers of isolated port.
The first step of mutual communication is to send the ARP message between the Sub-VLAN, if SUPERVLAN receives and can not find corresponding member behind the ARP message and just broadcast processing.Broadcasting area is all Sub-VLAN, if what be connected with certain Sub-VLAN is the Sub-VLAN of another SUPERVLAN, at this time message will be broadcast in another SUPERVLAN, the message of Fa Songing is secret messages (a privacy message) if desired, do not wish to be broadcast among another SUPERVLAN, only wish in this SUPERVLAN, to broadcast.
Except broadcasting, normal clean culture, if the newspaper that sends is a secret messages, we only also wish in this SUPERVLAN internal delivery, and do not wish to be forwarded among other SUPERVLAN.
In sum, when sending message, owing to can't know the fail safe of opposite end SUPERVLAN, when propagating between different SUPERVLAN, the fail safe of message is lower, but does not have the scheme of the communication between a kind of SUPERVLAN of control at present in the prior art.
