Abstract
The invention discloses a timer control method of a GVRP (GARP VLAN registration protocol) system. According to the method, each GARP (generic attribute registration protocol) entity extends in message information to set attribute information of four timers, when an exchanger and the GARP entity are in communication, the exchanger judges timer information in the message information of the GARP entity so as to enable attribute values of the four times in the exchanger to be consistent with the attribute value of the GARP entity through setting, the identical timer configuration is kept between each of a plurality of GARP entities participating in the GVRP and the exchanger, and the virtual local area network configuration in the GVRP system can keep stable. According to the timer control method based on the GARP entity of the GVRP, oscillation of the virtual local area network environment of the GVRP system can be avoided, and accordingly, the GVRP system performance and the user experience are improved.
Description
Technical field
The present invention relates to GARP timer collocation method, be specifically related to a kind of timer control method of GVRP system.
Background technology
Generic Attribute Registration Protocol (Generic Attribute Registration Protocol is called for short GARP).It is be between the exchange member in same switching network the means providing distribution, propagate, register certain information (attribute such as multicast mac address and VLAN).By GARP mechanism, the configuration information meeting bamboo telegraph on a GARP member is to whole switching network.
GARP itself is only a protocol specification, does not exist in a switch as an entity.The application entity following GARP agreement is called that GARP applies, and GARP main is at present applied as GVRP and GMRP.Agreement existence is in a switch embodied by various GARP application.
The propagation service of VLAN information between GVRP (GARP VLAN Registration Protocol-802.1P, 802.1Q) support equipment.Enabling in GVRP application, can the VLAN information of a manual configuration switch, other all switch in this network can the situation of those VLAN of dynamic knowledge.Terminal node can access any switch and be connected on required VLAN.Terminal will use GVRP just to need to install the network interface unit (Network Interface Card is called for short NIC) of GVRP compatibility.The NIC of GVRP compatibility can configure and join required VLAN or VLAN, then accesses a GVRP-enabled switch.Establish a communications link between NIC and switch, and achieve VLAN connectedness between, achieve the automation configuration of vlan, reduce the workload of manual configuration management.
In GVRP agreement, define 4 class timers: GARP protocol definition four kinds of timers maintain the change of state machines, the transmission of protocol message, the action such as registration, cancellation of attribute.Four kinds of timers are respectively: Hold timer, Join timer, Leave timer and LeaveAll timer.Wherein LeaveAll timer is the timer that the overall situation controls, and other three timers are relevant with each port.As long as a GARP protocol application entity management LeaveAll timer, but there is multiple participation port will have corresponding multiple Hold timer, Join timer and Leave timer.The unit of the timer that GARP agreement uses is centisecond (centsecond).
Summary of the invention
The object of the present invention is to provide a kind of timer control method of GVRP system, in its message information, the attribute information that four kinds of timers are set is expanded by GARP entity, when switch and GARP entity carry out communication, switch is by judging the timer information in the message information of GARP entity, thus the attribute value of the inner four kinds of timers of switch is set and GARP entity attributes value is consistent, the multiple GARP entity making to participate in GVRP agreement with maintain identical timer between switch and configure, VLAN configuration in GVRP system can be kept stable.Provided by the inventionly a kind ofly the concussion of the VLAN environment of GVRP system be can avoid based on the timer control method of GARP entity under GVRP agreement, GVRP systematic function and Consumer's Experience improved with this.
