These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. The word "if," as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination," depending on the context.
In order to facilitate understanding of the implementation method for loose coupling of the service board of the frame device, a tight coupling mode and a loose coupling mode of the service board are first described:
(1) Tight coupling mode:
please refer to fig. 1, which is a structural diagram of the internal structure of the frame device in the service board close coupling mode.
As shown in fig. 1, in the service board tight coupling mode, the main control board is connected to the CPU of the service board and the switch chip through the switch network board, for example, in fig. 1, the CPU of the service board uses an internal interface ieth0_1 as an interface of the main control service channel, the CPU of the main control board uses an internal interface ieth0_2 as another interface of the main control service channel, and the main control board manages the whole service board through the main control service channel. Therefore, in the service board close coupling mode, the software version operated by the service board CPU needs to be consistent with the software version operated by the main control board CPU.
Under the service board tightly coupled mode, the physical interface of the exchange chip of the service board and the CPU of the service board is registered as an internal port, adopts the Hig mode, and is set as an internal aggregation port. From the user use aspect, these internal aggregation ports are imperceptible to the user, and meanwhile, by adopting the Hig mode, the packet can be internally forwarded between the internal switching chips of the network device through the internal ports.
In the service board close coupling mode, the switching chip of the service board can also be connected with a box-type device to process services supported only by the box-type device, such as probe, through the box-type device. Furthermore, the cartridge device can independently run the software version without being consistent with the software version run by the main control board.
Based on the structure illustrated in fig. 1, in the service board tight coupling mode, after network traffic (equivalent to a message) enters the service board switching chip, the service board switching chip sends the network traffic to the service board CPU through an internal aggregation port between the service board switching chip and the service board CPU, so that the service board CPU performs service processing, such as traffic cleaning, intrusion prevention, and the like. Then, the service board CPU sends the processed network traffic to the service board switching chip through an internal aggregation port between the service board CPU and the service board switching chip, so as to be forwarded by the service board switching chip. Therefore, in the service board tightly-coupled mode, the whole frame type device is taken as a whole, and the forwarding process of the network flow between the service board switching chip and the service board CPU belongs to the frame type device internal forwarding.
(2) Loosely coupled mode
Please refer to fig. 2, which is a diagram illustrating an internal structure of a frame device in a service board loose coupling mode.
As shown in fig. 2, in the service board loose coupling mode, the main control board is connected to the switch chip of the service board through the switch network board, and the main control board is only responsible for managing the switch chip of the service board. Therefore, in the service board loose coupling mode, the software version operated by the service board CPU does not need to be consistent with the software version operated by the main control board CPU, in one example, the service board CPU can operate the software version operated by the box type device in fig. 1, and through the processing, the service board switching chip does not need to be connected with the box type device, thereby simplifying the networking structure.
In the loose coupling mode of the service board, the physical interface of the exchange chip of the service board and the CPU of the service board is registered as a panel port, and the IEEE mode is adopted. From the user use aspect, the panel ports are perceivable by the user, and meanwhile, by adopting the IEEE mode, the external forwarding of the message between different network devices through the panel ports can be realized.
Based on the structure illustrated in fig. 2, in the loose-coupling mode of the service board, after the network traffic enters the service board switching chip, the service board switching chip directly forwards the network traffic, and may forward the network traffic to the service board CPU for service processing, or forward the network traffic to another CPU for service processing, which is specifically determined by the destination address of the network traffic. Therefore, in the service board loose coupling mode, the service board is taken as a whole, and the forwarding process of the network traffic between the service board switching chip and the service board CPU belongs to external forwarding. As can be seen from the above description, the following drawbacks exist in the service board close coupling mode:
(1) When services supported by only the box-type device need to be used, the box-type device and the box-type device need to be deployed simultaneously in the networking structure, thereby increasing the complexity and the space occupation of the networking deployment.
(2) When the software version is upgraded, the main control board and the service board are required to update the software version synchronously, and the requirement that the service board runs a special software version cannot be supported.
(3) When the service board supports various services in a tight coupling mode, the service board branches of various products need to be maintained, which results in higher development investment cost.
In the service board loose coupling mode, the defects can be easily solved.
Based on this, the present application provides a method for implementing loose coupling of a service board of a frame device, which is described by the following embodiments:
referring to fig. 3, a flowchart of an embodiment of a method for implementing service board loose coupling of a frame device according to an exemplary embodiment of the present application is provided, where in an example, the method may be applied to a frame device, for example, a network security frame device, and includes the following steps:
step 301: when the main control board detects that the coupling flag bit is changed from a first value to a second value after restarting, the single board type of the slot position where the service board is located is initialized to be the interface board, and a physical interface connected with a CPU of the service board on a switching chip of the service board is registered as a panel port.
Step 302: and when the service board detects that the coupling flag bit is changed from the first value to the second value after restarting, registering a physical interface connected with a switching chip of the service board on a CPU of the service board as a panel port.
Step 301 and step 302 are collectively described below:
in this embodiment, the coupling flag bit may be used to indicate a coupling mode of the service board, and its value is two, and for convenience of description, the coupling flag bit is referred to as a first value and a second value, where when the coupling flag bit is the first value, the coupling mode of the service board is represented as tight coupling, and when the coupling flag bit is the second value, the coupling mode of the service board is represented as loose coupling.
As an example, the coupling flag bit can be stored in an EEPROM (Electrically Erasable Programmable Read-Only Memory), and the advantage of such processing is that: the value of the coupling flag bit is not erased when the power of the EEPROM is down.
As an example, an EEPROM may be respectively disposed on the main control board and the service board, and values of the coupling flag bits in the two EEPROMs are consistent.
In application, the value of the coupling flag bit can be changed from the first value to the second value manually by a user and the boxed device is controlled to restart.
In this embodiment of the present application, when the main control board detects that the value of the coupling flag bit is changed from the first value to the second value after the restart, the board type of the slot where the service board is located is initialized to the interface board, for example, the board type flag bit corresponding to the slot where the service board is located may be set as an interface board macro definition to initialize the board type of the slot where the service board is located to the interface board, and a physical interface connected to the CPU of the service board on the switch chip of the service board is registered as a panel port. Since the panel port is perceivable to the user, the user can set the rate and duplex mode of the panel port and can also manage the opening and closing of the panel port.
Similarly, when the service board detects that the value of the coupling flag bit is changed from the first value to the second value after the restart, the physical interface connected to the switching chip of the service board on the CPU of the service board is registered as a panel port in the initialization process.
In addition, the main control board can also set the interface mode of a physical interface connected with the CPU of the service board on the exchange chip of the service board as an IEEE mode; correspondingly, the service board sets the interface mode of the physical interface connected with the switching chip of the service board on the CPU of the service board to be the IEEE mode.
In addition, as can be seen from the above description, in the service board loose coupling mode, the service board may independently run the software version, and based on this, in an embodiment, the management port of the service board may be connected to another terminal, such as a PC, the service board may start the BIOS program after being restarted, and obtain the software version with the specified version number from the terminal connected to the management port, and after the service board is restarted, the service board CPU may run the obtained software version.
It should be noted that, the sequence between step 301 and step 302 in the flow shown in fig. 3 is only an example, and in practical applications, step 301 and step 302 may be executed synchronously.
So far, the description about the flow shown in fig. 3 is completed.
It can be seen from the above embodiments that, after the restart, when detecting that the coupling flag is changed from the first value to the second value, the main control board initializes the board type of the slot where the service board is located as the interface board, registers the physical interface connected to the CPU of the service board on the switch chip of the service board as the board port, and when detecting that the coupling flag is changed from the first value to the second value, registers the physical interface connected to the switch chip of the service board on the CPU of the service board as the board port, so that the coupling mode of the service board in the frame device can be changed from the tightly coupled mode to the loosely coupled mode.

Based on this, after the service board 42 receives the message, the switching chip 422 of the service board 42 directly forwards the received message, and the CPU421 of the service board 42 may serve as an external device to receive the message forwarded by the switching chip 422 of the service board 42 and perform service processing on the received message.
When the coupling mode of the service board 42 is tight coupling, the main control board 41 is connected to the switching chip 422 and the CPU421 on the service board 42 through the switching network board 43, so that the main control board 41 manages the service board 42; the switching chip 422 on the service board 41 is also connected to the CPU421 on the service board 41 via a respective registered internal aggregation port (not shown in fig. 4). Based on this, after the service board 42 receives the message, the switching chip 422 of the service board 42 sends the received message to the CPU421 of the service board 42 for service processing, and the switching chip 422 of the service board 42 forwards the processed message.
