Packet processing (hereinafter referred to as message processing component), policy control (hereinafter referred to as control component) and other components of multiple functions.

如图3中所示，控制器下挂多个宽带接入设备，北向连接业务服务器(如radius服务器、portal服务器等)，宽带接入设备接收宽带用户的业务相关报文，将报文投递到控制器集中处理，控制器将报文处理后，与业务服务器进行业务交互，之后将应答报文发送给宽带接入服务器，宽带接入服务器再返回给宽带用户。As shown in Figure 3, the controller hangs multiple broadband access devices, and connects to the service server (such as a radius server or a portal server) in the north. The broadband access device receives the service-related packets of the broadband users and delivers the packets to the packets. The controller processes the packet, and after the controller processes the packet, it performs service interaction with the service server, and then sends the response packet to the broadband access server, and the broadband access server returns to the broadband user.

The message processing component of the packet is recorded, and the user information is recorded, corresponding to the packet processing component, and then sent to the packet processing component through the output port in the group table.

进一步，报文处理组件对业务的报文进行处理，并上送到控制组件，控制组件与业务服务器进行交互，之后将业务服务器的应答报文发送给报文处理组件；同时控制组件将业务的处理结果发送给报文接收组件Further, the packet processing component processes the packet of the service and sends it to the control component, and the control component interacts with the service server, and then sends the response packet of the service server to the packet processing component; The processing result is sent to the message receiving component.

进一步，报文接收组件接收到控制组件的处理结果后，对mac表项进行处理。Further, after receiving the processing result of the control component, the packet receiving component processes the mac entry.

Return to broadband users

总体而言，本实施例通过openflow组表中的权重值的动态调整或通过用户mac的映射计算，实现宽带接入设备上送的业务相关报文，在不同的报文处理组件间进行负载分担，提高控制器对报文的处理性能，并可通过命令，在两种负载分担方式间灵活切换。两种方式中，通过openflow组表中的权重值的动态调整实现某一时间段内多个组件间并发处理报文的负载分担方式；通过用户mac的映射计算实现某一时间 段内多个组件间并行处理报文的负载分担方式。In general, in this embodiment, the service-related packets sent by the broadband access device are implemented through the dynamic adjustment of the weight value in the openflow group table or the mapping calculation by the user mac, and load sharing is performed between different packet processing components. The controller can improve the processing performance of packets, and can flexibly switch between the two load sharing modes through commands. In the two modes, the load balancing mode of concurrently processing packets between multiple components in a certain period of time is implemented by dynamically adjusting the weight value in the openflow group table; Load balancing mode for processing packets in parallel between multiple components in a segment.

下面通过对具体场景的描述来进一步说明：The following is further illustrated by a description of the specific scenario:

具体场景例1：Specific scenario example 1:

以用户接入报文为例，说明通过openflow组表中权重值的动态调整，使用户的接入报文在多个报文处理组件间以并发处理方式进行负载分担的实施过程。The user access packet is used as an example to describe the implementation of the load balancing of the user's access packets in the concurrent processing mode.

具体步骤为：The specific steps are:

步骤1：在控制器启动时，策略控制组件向报文接收组件下发openflow的组表，组表中内容主要包括：output端口－与控制器中的报文处理组件连接的端口，每个组表中可有多个output端口，每个output端口对应一个权重值，权重值由报文接收组件根据内部策略进行初始化，并设置为大小不同的值Step 1: When the controller is started, the policy control component sends an openflow group table to the packet receiving component. The contents of the group table mainly include: an output port - a port connected to the packet processing component in the controller, and each group There may be multiple output ports in the table, and each output port corresponds to a weight value. The weight value is initialized by the packet receiving component according to the internal policy, and is set to a value different in size.

步骤2：在控制器启动时，策略控制组件向报文接收组件下发各报文处理组件的性能指标，性能指标用途：指明每个报文处理组件在业务处理上的性能，性能值是一个区间的值，代表组件的性能已经达到了告警状态，在报文处理组件的性能达到此区间的下限时，表明组件已经满足切换条件，可由其他组件接手后续的业务报文处理工作，当组件的性能达到此区间的上限时，表明组件已经达到饱和状态，不能再处理业务报文，必须转由其他组件处理业务报文，否则会导致报文处理异常，当组件的性能再次下降到此区间的下限以下时，表明组件已解除警告状态，可作为备选组件处理业务报文。Step 2: When the controller is started, the policy control component sends the performance indicators of each packet processing component to the packet receiving component. The performance indicator uses: indicates the performance of each packet processing component in the service processing, and the performance value is a The value of the interval indicates that the performance of the component has reached the alarm state. When the performance of the packet processing component reaches the lower limit of the interval, it indicates that the component has met the switching condition, and other components can take over the subsequent service packet processing work. When the performance reaches the upper limit of the interval, it indicates that the component has reached the saturation state, and the service packet cannot be processed. The service packet must be processed by other components. Otherwise, the packet processing is abnormal. When the performance of the component falls again to this interval. Below the lower limit, the component has been de-asserted and can be used as an optional component to process business messages.

步骤3，报文接收组件接收到控制组件下发的openflow组表后，将output端口与北向的各报文处理组件建立对应关系；同时根据报文处理组件的初始化过程，为每一个output端口设定不同的权重值。Step 3: After receiving the openflow group table sent by the control component, the packet receiving component associates the output port with each packet processing component in the north direction; and sets the output port for each output port according to the initialization process of the packet processing component.
