Description
Technical field
The present invention relates to the transfer approach of field of communication technology more particularly to LAN protocol message, device and systems.
Background technique
Since the number of applications of enterprise gateway is bigger, hung under remote enterprise gateway under local side enterprise gateway, due to remote
Hold enterprise gateway unclear for the network environment of local side enterprise gateway, therefore remote enterprise gateway cannot specify in pre-configuration
Administrative vlan (Virtual Local Area Network, VLAN).It, need to be in beginning if not using zero configuration management
When, to remote enterprise gateway equipment, manual configuration, allocative efficiency are low one by one.According to zero configuration management, in remote enterprise net
Closing after equipment plugs cable can be used.Local side enterprise gateway can find remote enterprise gateway equipment using zero configuration automatically, and
VLAN, the information such as Internet protocol (Internet Protocol, IP) configuration, and configuration purpose address are distributed and managed for it
(Destination Network Address Translation, DNAT) rule is converted, for Simple Network Management Protocol
(Simple Network Management Protocol, SNMP) network management is managed concentratedly.
Since above-mentioned local side enterprise gateway is equivalent to dynamic host configuration protocol (Dynamic Host
Configuration Protocol, DHCP) client, above-mentioned remote enterprise gateway is equivalent to Dynamic Host Configuration Protocol server.Local side enterprise
Industry gateway uses the prior art of zero configuration to create band VLAN mark (Identification, id) in dhcp client
4094 interface packets, one interface packets of every creation are sent to Dynamic Host Configuration Protocol server.Dynamic Host Configuration Protocol server receives required message
Response message is sent to dhcp client afterwards, when dhcp client receives the response message, stops creation interface report immediately
Text and stop to Dynamic Host Configuration Protocol server transmission interface message.User space building is received in the linux kernel of dhcp client
After 0x0800 interface packets, that calls kernel is originally created Interface Flowchart, the interface packets after being originally created, then at this
VLANID is added in interface packets, so far interface packets creation finishes, wherein to avoid handling function in kernel dispatching process
Linkwatch_event operation is too frequent, and the execution time interval of function linkwatch_fire_event is set as one second.Cause
This, one interface packets of every creation need at least one second, then 4094 interface packets of creation then need 4094 seconds, i.e., more than one
The creation time of hour.Since the creation time of interface packets is too long, zero configuration, allocative efficiency are carried out according to the prior art
It will be extremely low.
In conclusion causing creation one to connect due to the scheduling flow overlong time for the linux kernel for calling dhcp client
Mouth message needs at least one second, therefore, carries out zero configuration using the prior art, allocative efficiency will be extremely low.
