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 data synchronization Distributed virtual local area networks, and more particularly to a method of distributed virtual configuration to ensure consistent inter-LAN subsystem.

背景技术 Background technique

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。 Other user equipment communicate with each VLAN of the VLAN (Virtual LAN) often adjacent thereto, which requires the user belongs to virtual local area network VLAN Registration Protocol (GVRP) by common attributes, message learned VLAN VLAN network device disposed adjacent to differentiate user equipment belongs to VLAN network and user equipment adjacent VLAN network, user equipment adjacent to learn to set VLAN network VLAN ID is dynamic VLAN, VLAN ID of the VLAN network user equipment set up 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 through the respective roads (Trunk) establishing communication with the adjacent port VLAN, when the user equipment to the access network VLAN adjacent, run GVRP / VTP, VLAN network user equipment belongs detection system connected thereto each trunk port status is determined trunk port is available, if the detected available trunk port, VLAN dynamic binding is established with the neighboring network VLAN trunk port, if it detects a trunk port is not available, then neighboring network VLAN dynamic VLAN aging, learning from the trunk port to dynamic VLAN are all aging, namely: unbind all the 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。 In the VLAN network user equipment belongs, all the binding relationship with the dynamic VLAN trunk ports eventually be delivered to the network processor use.

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V Process and dynamic VLAN trunk port binding relationship to establish or release shown in FIG. 1, FIG. 1 is a configuration diagram of the dynamic VLAN trunk port binding relationship to establish or release, specific process is described as: VLAN network system user equipment belongs subsystem 101 by subsystem 100 and VLAN network VLAN network, where, GVRP subsystem 100 includes a management module 102 and the interface module 103, 100 for connecting the two wires GVRP subsystem module 102 and interface management module 103, the left line represents the dynamic VLAN network VLAN GVRP learning module adjacent to establish a binding relationship with the trunk port, the line on the right indicates the module aging GVRP dynamic VLAN adjacent VLAN network, unbind and trunk ports , establishing whether or aging bound trunk port, the direction of the two lines are GVRP / VTP management module 102 to the interface module 103; the configuration subsystem 101 includes a message processing module 104, the interface management module 103 and the message processing module 104 configured increase line between the representation of: a binding relationship with the dynamic VLAN trunk port is sent by the interface module 103 to the configuration management message processing module 104, i.e., establishing a dynamic V LAN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。 LAN port binding relationship with the trunk, or unbind and dynamic VLAN trunk port, then this message by sending the configuration message processing module 104 configured to a VLAN network processor user belongs.

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。 VLAN dynamic data structure for ease of handling and efficiency VLAN network system, the interface management module 103 adjacent VLAN network indicating whether there is the presence of dynamic VLAN flag, when the dynamic VLAN aging, and releasing the dynamic VLAN corresponding binding relationship trunk ports, dynamic VLAN VLAN network system that will remove the user belongs to, the presence of the flag of the 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 releasing the interface management module 103 send a configuration message to the binding subsystem 101, there may be cases configuration message loss occurs, in order to avoid this situation, prior art uses periodic refresh strategy, i.e., subsystem starts a timer 100, the transmission timing of all neighboring dynamic VLAN configuration to the VLAN network subsystem 101, the refresh dynamic VLAN message subsystem 101.

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。 However, this method of periodically refresh the dynamic VLAN of the VLAN aging neighboring network is not feasible, when the dynamic VLAN aging, the dynamic VLAN is deleted, the presence of the dynamic VLAN flag will be deleted after the reset, the refresh process the presence of the flag of the query 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 the existing flag bit is reset, the process will be refreshed dynamic VLAN skipped, i.e., the refresh process is not refresh the dynamic VLAN, the VLAN dynamic current configuration message can not be issued by the subsystem to the subsystem 101 to 100, and therefore, Once released the corresponding dynamic VLAN trunk port binding configuration message is lost, the method can not do anything regularly updated, resulting in a network system between distributed subsystems VLAN configuration inconsistencies.
