The multi-frame cascading scheme commonly used in the industry is a first-level star connection, that is, one main frame is connected to multiple slave frames, the main frame exchange board and each There is a physical connection between the slave switchboards. There is no connection between the slave and the slave switchboard. The data exchange between any two slaves must be forwarded through the switchboard of the primary chassis. As shown in Figure 1.
这种连接方式下，一个从框和主框间连线出现问题，只会影响到这个从框，其他从框不受影响，这也是目前业界普遍采用星型连接方式的主要原因；另外，星型连接只有主框交换板需要保存路由表，负责框间数据转发，软件上比较容易实现，维护简单。但是这种连接方式受限于主框交换板的处理能力和面板上级连口的个数，往往不可能连太多的框，网络扩容受影响。另外，主框交换板如果出现故障，系统中所有的跨框通信业务将受影响。In this connection mode, a problem occurs between the connection between the frame and the main frame, which only affects the slave frame, and the other slave frames are not affected. This is the main reason why the star connection method is generally adopted in the industry at present; Only the main frame switch board needs to save the routing table and is responsible for data forwarding between frames. The software is easy to implement and easy to maintain. However, the connection mode is limited by the processing capacity of the main chassis switch board and the number of upper-level interfaces on the panel. It is often impossible to connect too many frames, and network expansion is affected. In addition, if the main frame switch board fails, all cross-frame communication services in the system will be affected.
因此，可以看出上述一级星型连接系统存在系统扩容难、可靠性低等方面的问题。Therefore, it can be seen that the above-mentioned first-level star connection system has problems in that system expansion is difficult and reliability is low.

Here, the switch frame is a frame device that implements message exchange control, and the resource frame is a box device that performs service processing on the message. The switch box contains multiple switch boards (at least two) that process the packets across the board. The resource box contains the switch board that forwards the packets and the service board that processes the service. There are usually two switch boards in the resource box. The service board sets one or more blocks according to system requirements and business processing needs. The switch board in the switch chassis only provides cross-frame routing to implement data forwarding across frames.

That is, the switch board and the resource box in each switch frame form a star connection, so that the entire system has a secondary star structure. . The switch board in the central switch board group is the center switch board. The switch boards in the non-central switch board group are non-center switch boards.
为提高系统的可靠性，交换框内一个交换板只能作为一个交换板组的成员，不能同时作为两个或两个以上交换板组的成员。此时，其中一组交换板为中心交换板组，其他为非中心交换板组，非中心交换板组和中心交换板组之间星型连接，每组交换板组可以通过资源框内的交换板连接多个资源框，即每组交换板组和资源框之间又构成星型连接，使整个系统呈二级星型结构，如图2所示：To improve system reliability, a switch board in a switch chassis can only be a member of a switch board group and cannot be a member of two or more switch board groups at the same time. In this case, one of the switch boards is a central switch board group, the other is a non-center switch board group, and the non-center switch board group and the center switch board group are connected by a star. Each group of switch boards can be exchanged in a resource box.

The two switch boards in each group in the switch chassis work in active/standby mode or load sharing mode.
交换框内的每组交换板组和所述资源框内的交换板均可以通过物理连线相互连接。交换框内每组交换板组可以连接多个资源框。本实施例中，资源框间无需通过物理连线连接，任意两个资源框间数据转发都需要通过交换框实现。Each group of switchboards in the switch frame and the switchboards in the resource frame can be connected to each other through physical connections. Each resource switch group in the switch box can be connected to multiple resource frames. In this embodiment, the resource frames need not be connected through physical connections, and data forwarding between any two resource frames needs to be implemented through a switch frame.
所述的交换框内的其中一组交换板组为中心交换板组，其他组为非中心交换板组。每组非中心交换板组和中心交换板组之间均可以通过物理连线连接。非中心交换板组之间则不需要物理连线。One of the switch board groups in the switch frame is a central switch board group, and the other groups are non-center switch board groups.

The egress port is the port connected to the central switch board. When the packet fails to find a route, the default route is taken to the central switch board. This is simple and reliable. The central switch board saves the switch board connection. The service board routes to all resource boxes and the network segment routes to other resource boxes.

The steps of the data exchange method based on the multi-frame interconnection system provided by the embodiment of the present invention are described in detail in the resource frame of the switch board connection:
步骤A：业务板A向业务板B发送数据，目的MAC为一特定的MAC。Step A: The service board A sends data to the service board B, and the destination MAC is a specific MAC.
步骤B：资源框0内交换板收到报文后，根据二层交换将报文发送到和交换框相连的端口。Step B: After receiving the packet, the switch board in resource frame 0 sends the packet to the port connected to the switch frame according to the Layer 2 switch.

The service board A is in a resource frame that is not connected to the central board, and the service board C is in the resource box that is connected to the central switch board. The steps of the data exchange method of the multi-frame interconnection system are described in detail:
步骤a：业务板A向业务板C发送数据，目的MAC为一特定的MAC。Step a: The service board A sends data to the service board C, and the destination MAC is a specific MAC.
步骤b：资源框0内交换板收到报文后，根据二层交换将报文发送到和交换框相连的端口。Step b: After receiving the packet, the switch board in resource box 0 sends the packet to the port connected to the switch frame according to the Layer 2 switch.
步骤c：交换框内交换板A收到报文后，通过缺省路由则将报文送至和中心交换板相连端口。Step c: After receiving the packet, the switch board A sends the packet to the port connected to the central switch board through the default route.

业务板A和B、C所在的资源框都挂接在不同的交换板下，所以必须经过中心交换板的转发，当源板和目的板所在的资源框挂接在同一组交换板下时，则不需要经过中心交换板。The resource frames of the service boards A and B and C are connected to different switch boards. Therefore, you must forward them through the central switch board. When the resource frames where the source board and the destination board are located are connected to the same switch board, You do not need to go through the central switchboard.

1、本发明实施例提供的多框互联系统设有单独的交换框，内有多块交换板，可以连接更多的资源框，增强了系统的处理能力，扩大了系统的容量。并且，当一个交换框所连接的资源框个数无法满足需求时，还可以通过以多 个交换框间构成星型连接，将系统扩展为三级甚至更多级的星型连接，图9给出了三级星型连接的示意图。可见，本实施例的系统实现扩容只需要增加交换板或交换框的个数，方便了系统扩容。The multi-chassis interconnection system provided by the embodiment of the present invention has a separate switch frame, and has multiple switch boards, which can connect more resource frames, enhance the processing capability of the system, and expand the capacity of the system. Moreover, when the number of resource frames connected to a switch box cannot meet the requirements, The exchange boxes form a star connection, which expands the system into three or more levels of star connections. Figure 9 shows a schematic diagram of a three-level star connection. It can be seen that the system in this embodiment only needs to increase the number of switch boards or switch frames to facilitate system expansion.
2、本实施例中多组交换板都承担跨框数据转发，一组交换板故障，不会导致整个系统框间通信异常，且每组交换板组间是主备或负荷分担工作，提高了系统可靠性。2. In this embodiment, multiple switch boards are in the process of forwarding data across the chassis. If a group of switch boards is faulty, the communication between the entire system is not abnormal, and the switch boards in each group are active/standby or load-sharing. System reliability.
3、另外，非中心交换板上保存到中心交换板的路由条目仅一条，减少了软件上保存的路由表项，便于系统维护。3. In addition, only one routing entry is saved to the central switching board on the non-central switching board, which reduces the routing entries saved in the software and facilitates system maintenance.
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权力要求书的保护范围为准。The above is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or within the technical scope disclosed by the present invention.
