保证分布式虚拟局域网中子系统间配置一致的方法 Guarantee Distributed Virtual LAN configuration subsystems consistent approach

技术领域 FIELD

本发明涉及分布式虚拟局域网中的数据同步技术,特别涉及保证分布式虚拟局域网中子系统间配置一致的方法。 The present invention relates to a distributed virtual LAN data synchronization technology, in particular to ensure consistency between the method of configuring a distributed virtual LAN subsystem.

背景技术 BACKGROUND

用户设备所属VLAN(虚拟局域网)常常与其相邻的其他VLAN相互通信,这就要求用户所属VLAN通过通用属性注册虚拟局域网协议(GVRP),学习到相邻VLAN网络设备所设置的VLAN消息,为了区分用户设备所属VLAN网络和用户设备相邻的VLAN网络,用户设备学习到相邻VLAN网络设置的VLAN标识为动态VLAN,用户设备所属VLAN网络设置的VLAN标识为静态VLAN。 User devices communicate with each other VLAN belongs VLAN (Virtual LAN) often adjacent, which requires the user belongs to a virtual local area network VLAN Registration Protocol by common attributes (GVRP), learning to VLAN VLAN news network equipment set adjacent to distinguish user device belongs VLAN network and user equipment adjacent VLAN network, the user equipment to the adjacent VLAN learning network settings for dynamic VLAN ID VLAN, VLAN and VLAN network identifies a user equipment set for a static VLAN.

用户设备所属的VLAN网络通过各个干道(trunk)端口与相邻的VLAN建立通信,当用户设备要接入相邻VLAN网络时,会运行GVRP/VTP,用户设备所属的VLAN网络系统检测与其相连的各个trunk端口的状态,判断trunk端口是否可用,如果检测到trunk端口可用,则建立相邻VLAN网络的动态VLAN与该trunk端口的绑定,如果检测到trunk端口不可用,则相邻VLAN网络的动态VLAN老化,从该trunk端口学习到的动态VLAN将被全部老化,即:解除动态VLAN与该trunk端口的所有绑定。 VLAN network user equipment belongs to each trunk port to establish communication through (trunk) and adjacent VLAN, when users want to access the adjacent VLAN network equipment, will run GVRP / VTP, VLAN network user equipment belongs to detect the connected each trunk port status, determine the trunk port is available, if it detects a trunk port is available, the establishment of a dynamic VLAN VLAN network adjacent to the trunk port binding, if it detects a trunk port is unavailable, the neighboring network VLAN Dynamic VLAN aging, learning from the trunk port to dynamic VLAN will be full of aging, namely: remove all the bindings dynamic VLAN trunk port. 在用户设备所属的VLAN网络中,所有动态VLAN与trunk端口的绑定关系最终要下发给网络处理器使用。 Internet users in VLAN the device belongs, all the binding relationship with the dynamic VLAN trunk port ultimately distributed to the network processor.

动态VLAN与trunk端口建立或解除绑定关系的过程如图1所示,图1为动态VLAN与trunk端口建立或解除绑定关系的结构图,其具体过程描述为:用户设备所属的VLAN网络系统是由VLAN网络的子系统100和VLAN网络的子系统101组成,其中,子系统100包括GVRP模块102和接口管理模块103,子系统100中的两条线用于连接GVRP模块102和接口管理模块103,左边的线表示GVRP模块学习到相邻VLAN网络的动态VLAN,建立与trunk端口的绑定关系,右边的线表示GVRP模块老化相邻VLAN网络的动态VLAN,解除与trunk端口的绑定关系,无论建立或老化trunk端口的绑定,两条线的方向均是由GVRP/VTP模块102到接口管理模块103;子系统101包括配置消息处理模块104,接口管理模块103与配置消息处理模块104之间的加重线表示:将动态VLAN与trunk端口的绑定关系由接口管理模块103发送到配置消息处理模块104,即建立动态VLAN与trunk端口的绑定关系,或解除动态VLAN与trunk端口的绑定关系,再通过该配置消息处理模块104下发配置消息给用户所属的VLAN网络处理器。 Dynamic VLAN and trunk ports to establish or unbind the process shown in Figure 1, Figure 1 is a dynamic VLAN and trunk ports to establish or unbind the diagram, the specific process is described as: VLAN network user device belongs by VLAN network subsystem 100 and VLAN network subsystems 101, of which, the subsystem 100 includes GVRP module 102 and interface management module 103, subsystem 100 is used to connect the two lines GVRP module 102 and interface management module 103, the left line represents the learning modules into adjacent GVRP dynamic VLAN VLAN network, establish a binding relationship with the trunk port, the right of the line represents the adjacent module aging GVRP dynamic VLAN network VLAN, unbind and trunk ports , whether established or aging bound trunk port, the direction of the two lines are from the GVRP / VTP management module interface module 102 to 103; subsystem 101 includes a configuration message processing module 104, interface management module to configure message processing module 103 and 104 aggravation between the lines, said: Binding relationship with dynamic VLAN trunk port 103 sent by the interface management module to configure message processing module 104, namely the establishment of binding relationship with the dynamic VLAN trunk ports or lift a dynamic VLAN and trunk ports binding relationship, and then through the configuration message processing module 104 next configuration message sent to the user belongs to VLAN network processor.

为了方便处理和提高VLAN网络系统的效率,接口管理模块103中相邻VLAN网络的动态VLAN数据结构中有表示该动态VLAN是否存在的存在标志位,当该动态VLAN老化时,解除该动态VLAN与相应trunk端口的绑定关系,该动态VLAN将从用户所属的VLAN网络系统中删除,该动态VLAN的存在标志位复位。 In order to facilitate processing and improve the efficiency of the system VLAN network interface management module 103 adjacent dynamic VLAN VLAN network data structure indicating the existence of dynamic VLAN exists flag, when the dynamic VLAN aging, lifting the dynamic VLAN and the binding between the corresponding trunk port, VLAN dynamic VLAN network system that will delete the user belongs, there are flags that dynamic VLAN reset. 但是,当接口管理模块103向子系统101下发解除绑定的配置消息时,有可能出现配置消息丢失的情况,为了避免这种情况的发生,现有技术采用定时刷新的策略,即子系统100启动定时器,定时将所有相邻VLAN网络的动态VLAN配置情况发送到子系统101中,刷新子系统101中的动态VLAN消息。 However, when the interface management module 103 to 101 issued under sub-lift configuration message binding, it is possible to configure the message is lost in the situation, in order to avoid this from happening, the existing technology uses timed refresh strategy, that subsystem 100 to start the timer, the timer will send dynamic VLAN configuration VLAN network all adjacent to the subsystem 101, refresh subsystem 101 dynamic VLAN message.

但这种定时刷新的方法对于相邻VLAN网络的动态VLAN老化是不可行的,当该动态VLAN老化时,该动态VLAN将被删除,删除后该动态VLAN的存在标志位将被复位,刷新流程将查询该动态VLAN的存在标志位。 But the timing of the refresh method for dynamic VLAN aging adjacent VLAN network is not feasible when the dynamic VLAN aging, the dynamic VLAN will be deleted after deleting the dynamic VLAN exists flag will be reset and refresh process The flag of the query exist dynamic VLAN. 如果该存在标志位被复位,该动态VLAN将被刷新流程跳过,即刷新流程不刷新该动态VLAN,该动态VLAN当前的配置消息就不能由子系统100下发到子系统101中去,因此,一旦解除动态VLAN与相应trunk端口绑定的配置消息丢失,定时刷新的方法也无能为力,造成分布式VLAN网络系统中的子系统间配置不一致的问题。 If this flag is reset exist, the dynamic VLAN will be refreshed processes skipped that refresh process does not refresh the dynamic VLAN, the dynamic VLAN information on the current configuration is not issued by the subsystem to subsystem 100 to 101, and therefore, Once the lifting of the corresponding dynamic VLAN trunk port binding configuration message is lost, regularly updated methods can not do anything, cause between distributed network systems VLAN subsystem configuration inconsistencies.

预先设置刷新次数阈值,该方法进一步包括:在每次对已被删除动态VLAN进行刷新后,判断该动态VLAN的刷新次数是否达到刷新次数阈值,如果没有达到,则将刷新次数加1;否则,将该动态VLAN的老化标志位复位,并将该动态VLAN从每个子系统中删除。 Refresh preset threshold number, the method further comprising: after each dynamic VLAN has been removed for refresh, refresh times to determine whether the dynamic VLAN refresh frequency threshold has not been met, then refresh the number of plus 1; otherwise, The dynamic VLAN aging flag reset, and the dynamic VLAN is deleted from each subsystem.
