However, due to its broadcast characteristics, Ethernet has also created a very fragile side of Ethernet.

由于网络连线不规范、碰线等原因致使整个网络的数据转发路径存在环路，这种环路称为以太网环路。由此引发的危害主要包括广播风暴、 MAC地址漂移、转发表错乱等，从而导致整个网络的阻塞和中断。除了以太网环路问题之外，网络攻击所导致的 MAC地址频繁漂移，也是影响网络性能和安全的重要因素。 Because the network connection is not standardized, and the line is touched, the data forwarding path of the entire network is looped. This type of loop is called an Ethernet loop. The resulting hazards mainly include broadcast storms, MAC address drift, and forwarding table confusion, which cause congestion and interruption of the entire network. In addition to the Ethernet loop problem, frequent MAC address drift caused by network attacks is also an important factor affecting network performance and security.

为使本发明的目的、技术方案和优点更加清楚明白，下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。 In order to make the objects, the technical solutions and the advantages of the present invention more clearly, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be arbitrarily combined with each other.

图 1为本发明实施例中 MAC地址漂移的控制方法的流程图，如图 1所示，包括： FIG. 1 is a flowchart of a method for controlling MAC address drift in an embodiment of the present invention. As shown in FIG. 1, the method includes:

步骤 11、根据接收到的报文对应的转发实例信息，获取 MAC地址漂移使能标记。 Step 11: Obtain a MAC address drift enable flag according to the forwarding instance information corresponding to the received packet.

交换机或者分组传送网 ( PTN , Packet Transport Network )设备通常可以实现多个桥（bridge )或者二层虚拟专用网络（L2VPN )实例，每个实例独立完成各自的 MAC地址学习功能。在本发明实施例中，在 bridge/12vpn实例信息的控制表中，新增一个控制标记，即 MAC 地址漂移使能 ( MAC— Transfer— Enable ) , 用于表示是否允许 MAC地址漂移，比如：可以设置 0表示不允许 MAC地址漂移； 1表示允许 MAC地址漂移。 A switch or packet transport network (PTN, Packet Transport Network) device can usually implement multiple bridges or Layer 2 virtual private network (L2VPN) instances, each of which independently performs its own MAC address learning function. In the embodiment of the present invention, a control flag is added in the control table of the bridge/12vpn instance information, that is, MAC address drift enable (MAC_Transfer-Enable), which is used to indicate whether MAC address drift is allowed, for example: Setting 0 means that MAC address drift is not allowed; 1 means that MAC address drift is allowed.

步骤 12、确定 MAC地址表中 MAC地址条目的端口号与报文流入的端口号是否一致，在 MAC地址表中 MAC地址条目的端口号与接收到的报文流入的端口号不一致时，根据获得的 MAC地址漂移使能标记控制 MAC地址漂移。 Step 12: Determine whether the port number of the MAC address entry in the MAC address table is consistent with the port number in which the packet flows. When the port number of the MAC address entry in the MAC address table is inconsistent with the port number of the received packet, The MAC address drift enable flag controls the MAC address drift.

本步骤中，在 MAC地址表中查找与接收到的报文匹配的 MAC地址条目，如果查找到，则判断 MAC地址条目的端口号与接收到的报文流入的端口号是否一致，如果一致，则刷新 MAC地址条目中的 MAC地址老化时间，具体实现属于本领域技术人员的公知常识，这里不再赘述，这里强调的是在 MAC 地址条目的端口号与接收到的报文流入的端口号一致时，才进行刷新；如果不一致，则继续查询获得报文所属的转发实例，并根据获得的 MAC地址漂移使能标记控制 MAC地址漂移。其中， In this step, the MAC address entry matching the received packet is searched in the MAC address table. If the MAC address entry is matched, the port number of the MAC address entry is consistent with the port number of the received packet. Then, the aging time of the MAC address in the MAC address entry is refreshed, and the common knowledge of those skilled in the art is implemented. The details are not described herein. The port number of the MAC address entry is the same as the port number of the received packet. If it is inconsistent, continue to query to obtain the forwarding instance to which the packet belongs, and control the MAC address drift according to the obtained MAC address drift enable flag. among them,

根据获得的 MAC地址漂移使能标记控制 MAC地址漂移包括： According to the obtained MAC address drift enable flag control MAC address drift includes:

如果判断出 MAC— Transfer— Enable标记的值显示为不允许如为 0,则不允许 MAC地址漂移，结束本流程；如果该值显示为允许如为 1 ,则进一步包括：可以根据报文流入的端口的优先级信息进一步判断，如果 MAC地址条目指向的端口优先级高于接收到的报文流入的端口的优先级，则不允许 MAC 地址条目进行漂移，结束本发明实施例的流程；如果 MAC地址条目指向的端口优先级低于或等于接收到的报文流入的端口的优先级，则允许 MAC地址条目进行漂移，将该 MAC地址条目中的来源端口号和指向的端口优先级更新为报文的来源端口及优先级。 If it is determined that the value of the MAC-Transfer-Entry flag is not allowed to be 0, the MAC address drift is not allowed, and the process is ended; if the value is displayed as allowed as 1, it further includes: Further, according to the priority information of the port in which the packet flows, the MAC address entry is not allowed to drift if the priority of the port pointed to by the MAC address entry is higher than the priority of the port in which the received packet flows, and the implementation of the present invention is terminated. The flow of the example; if the priority of the port pointed to by the MAC address entry is lower than or equal to the priority of the port in which the received packet flows, the MAC address entry is allowed to drift, and the source port number and the pointed address in the MAC address entry are The port priority is updated to the source port and priority of the packet.

相关技术的实例可能包括多个端口，端口又对应相应优先级。如果希望通过修改端口优先级禁止漂移时，就需要在该实例下所有端口和优先级中查找，而本发明实施例中，通过本发明实施例中新增的 MAC— Transfer— Enable 标记，只需修改实例的全局配置，就在端口优先级的基础上提供了全局控制，即简单实现了对 MAC地址漂移的控制，同时也更加方便了工程维护和使用。 An example of a related art may include multiple ports, which in turn correspond to respective priorities. If you want to disable the drift by modifying the port priority, you need to look up all the ports and priorities in the instance. In the embodiment of the present invention, only the MAC-Transfer-Enable flag added in the embodiment of the present invention is required. Modifying the global configuration of the instance provides global control based on the port priority, which simply controls the MAC address drift and facilitates project maintenance and use.

以简单的方法实现交换机或者 PTN设备的 MAC地址漂移控制。 The MAC address drift control of the switch or PTN device is implemented in a simple manner.

As shown in FIG. 2, the device includes an ear module, a comparison module, a control module, and a storage module for storing a MAC address table. among them,

控制模块，设置为在接收到来自比较模块的第一通知时，根据获得的 MAC地址漂移使能标记控制 MAC地址漂移，具体设置为： The control module is configured to, when receiving the first notification from the comparison module, control the MAC address drift according to the obtained MAC address drift enable flag, and the specific setting is:

根据报文流入的端口的优先级对媒体接入控制地址漂移进行控制：判断 MAC地址条目指向的端口的优选级是否高于接收到的 ^艮文流入端口的优选级，如果高于，则不允许 MAC地址漂移，如果低于或等于，则允许 MAC地址漂移。 Controlling the media access control address drift according to the priority of the port in which the packet flows: determining whether the preferred level of the port pointed to by the MAC address entry is higher than the preferred level of the received inflow port, if higher, not MAC address drift is allowed. If it is lower than or equal to, MAC address drift is allowed.

在允许 MAC地址漂移时，所述控制模块还设置为：将该 MAC地址条目中的来源端口号和指向的端口优先级分别更新为报文的来源端口及优先级。比较模块还设置为，在确定出 MAC地址表中 MAC地址条目的端口号与接收到的报文流入的端口号一致时，向控制模块发送第二通知；相应地，控制模块还设置为，在接收到来自比较模块的第二通知时，不做处理。本发明实施例提供的控制装置可以设置在网络设备，如分组传送网络When the MAC address is allowed to drift, the control module is further configured to: The source port number and the port priority pointed to are updated to the source port and priority of the message. The comparison module is further configured to: send a second notification to the control module when determining that the port number of the MAC address entry in the MAC address table matches the port number of the received message; accordingly, the control module is further configured to When the second notification from the comparison module is received, no processing is performed. The control device provided by the embodiment of the present invention may be set in a network device, such as a packet transmission network.

In this embodiment, a packet transport network device is taken as an example to describe a specific process for implementing MAC address drift control according to the embodiment of the present invention. It is assumed that the packet transport network device in this embodiment is a centralized PTN device, and one master control switch board and two The block service interface board is composed of a motherboard, and the motherboard adopts an LSI company APP series network processor, which is responsible for searching and processing various service tables, and the service interface board is responsible for receiving and transmitting services. In this embodiment, it is assumed that the value of MAC_Transfer_Enable is 0, indicating that MAC address drift is not allowed, and the value of MAC_Transfer_Enable is 1 to allow MAC address drift. As shown in Figure 3, the specific implementation steps are as follows: Step 301: The main control board receives the packet from the interface board. The network processor obtains the instance number of the forwarded packet according to the inbound port of the packet.

步骤 302:根据转发实例编号，查询实例信息，获得 MAC— Transfer— Enable 标记。 Step 302: Query the instance information according to the forwarding instance number, and obtain the MAC_Transfer_Enable flag.

步骤 303〜步骤 305:查询 MAC地址表，如果没有查询到 MAC地址条目，则新增 MAC地址条目并结束处理，如果查询到 MAC地址条目，则进入步骤 306。 Step 303 to step 305: Query the MAC address table. If the MAC address entry is not queried, the MAC address entry is added and the processing ends. If the MAC address entry is queried, the process proceeds to step 306.

步骤 306〜步骤 307: 判断 MAC地址条目的端口号和 4艮文的入端口号是否一致，如果 MAC地址条目的端口号和 ^艮文的入端口号一致，则刷新 MAC 地址条目中的 MAC地址老化时间并结束处理，如果 MAC地址条目的端口号和 "^文的入端口号不一致，则进入步骤 308。 Step 306 to step 307: It is determined whether the port number of the MAC address entry is the same as the port number of the 4艮 file. If the port number of the MAC address entry and the inbound port number of the message are the same, the MAC address in the MAC address entry is refreshed. The aging time ends and the process ends. If the port number of the MAC address entry does not match the entry port number of the ^^ file, the process proceeds to step 308.

步骤 308：判断 MAC— Transfer— Enable 的值是 0 还是 1 , 如果 MAC— Transfer— Enable为 0, 则转步骤 309, 如果是 1 , 则转步骤 310。 Step 308: Determine whether the value of MAC_Transfer_Enable is 0 or 1. If MAC_Transfer_Enable is 0, go to step 309. If yes, go to step 310.

步骤 309: 不允许 MAC地址漂移并结束处理。步骤 310〜步骤 312: 判断 MAC地址条目指向的端口优先级是否高于数据报文流入端口的优先级，如果高于，则不允许 MAC地址漂移，如果低于或等于，则允许 MAC地址漂移。 Step 309: The MAC address is not allowed to drift and the processing ends. Steps 310 to 312: Determine whether the priority of the port pointed to by the MAC address entry is higher than the priority of the data packet inflow port. If it is higher, the MAC address is not allowed to drift. If it is lower than or equal to, the MAC address is allowed to drift.
