Here, the first message and the second message have the same message encapsulation format, and the message encapsulation format includes: magic number, message type, process identification ID, message length, message content and crc check value of the message. The magic number identifies the beginning of a message, the message type is used for identifying the specific type of the message, and the message type comprises the port configuration message, the port LED state control message and the like; the process ID is used to indicate which process the message originated from, and is 0 by default.
Here, two types of communication modes exist between the main control chip and the control chip, one is synchronous message, and the other is asynchronous message, and the asynchronous message can improve the parallel capability of the MDU and improve the processing efficiency.
Here, in order to enable the switching control chip to perform information transmission with the master control information, the method further includes: when the main control chip sends a synchronous message to the exchange control chip, the exchange control chip establishes a first server, and the first server simultaneously supports at least 32 communication connections; when the exchange control chip sends an asynchronous message to the main control chip, the main control chip establishes a second server, and the second server simultaneously supports at least 32 communication connections.
Specifically, for example, when the current process of the main control chip sends a synchronization message to the switching control chip, the process waits for a response returned by the switching control chip within a set time. Therefore, the switching control chip needs to establish a first server and create a first listening port (for example, the listening port may be defined as 10001), and the switching control chip listens to the message sent by the main control chip through the first listening port. When the current process of the main control chip sends a certain synchronous message to the exchange control chip, the main control chip establishes a TCP connection to the first server, and after the message interaction is completed, the TCP connection of the first server is ended.
Here, since the main control chip is a chip including multiple processes/threads, multiple connections to the switching control chip may be established at the same time, and therefore, the first server of the switching control chip needs to support at least 32 communication connections at the same time.
For example, asynchronous messages can be divided into two types, the first type is that asynchronous messages are sent by a main control chip, and the second type is that asynchronous messages are sent by a switching control chip.
When the current process of the main control chip sends an asynchronous message to the exchange control chip, the current process does not wait for the response of the exchange control chip. When the switching control chip sends out an asynchronous message, the main control chip needs to establish a second server and create a second listening port (for example, the port may be defined as 10002), and likewise, the second server supports at least 32 communication connections at the same time.
Further, in this embodiment, the first message, the port configuration message, the port LED status control message, the data stream creation message, the MDU upgrade message, the active partition setting message, the DSCP priority mapping configuration message, the port return status configuration message, the uplink speed limit configuration message, and the downlink speed limit configuration message are asynchronous messages;
the acquisition port state report message, the heartbeat message, the acquisition current active zone message, the 802.1X message control message, the uplink speed limit acquisition message and the downlink speed limit acquisition message are synchronous messages.
S112, the exchange chip executes corresponding communication service operation based on the second message;
and when the switching chip receives the second message forwarded by the control chip, executing corresponding communication service operation based on the second message.
For example, when the second message is a port configuration message, the switch chip configures corresponding port information according to the port configuration message.
Thus, the master control chip realizes the management of the exchange chip, thereby realizing the configuration of the communication service.
Based on the same inventive concept, the invention also provides an MDU, which is detailed in the second embodiment.

The magic number identifies the beginning of a message, the message type is used for identifying the specific type of the message, and the message type comprises the port configuration message, the port LED state control message and the like; the process ID is used to indicate which process the message originated from, and is 0 by default.
Here, there are two types of communication modes between the main control chip 21 and the control chip 22, one is synchronous message, and the other is asynchronous message.
When the main control chip 21 sends a synchronization message to the switching control chip 22, the switching control chip 22 establishes a first server, and the first server supports at least 32 communication connections simultaneously; when the switching control chip sends an asynchronous message to the main control chip, the main control chip 21 establishes a second server, and the second server supports at least 32 communication connections at the same time.
Specifically, for example, when a current process of the main control chip 21 sends a synchronization message to the switching control chip 22, the process waits for a response returned by the switching control chip 22 within a set time. Therefore, the switching control chip 22 needs to establish a first server and create a first listening port (for example, the listening port may be defined as 10001), and the switching control chip 22 listens to the message sent by the main control chip 21 through the first listening port. When the current process of the main control chip 21 sends a synchronization message to the switching control chip 22, the main control chip 21 establishes a TCP connection to the first server, and after the message interaction is completed, the TCP connection of the first server is terminated.
Here, since the main control chip 21 is a chip including multiple processes/threads, multiple connections to the switching control chip 22 may be established at the same time, and thus the first server of the switching control chip needs to support at least 32 communication connections at the same time.
For example, the asynchronous messages can be divided into two types, the first type is asynchronous messages sent by the main control chip 21, and the second type is asynchronous messages sent by the switching control chip 22.
After the current process of the main control chip 21 sends an asynchronous message to the switching control chip 22, the current process does not wait for the response of the switching control chip 22. When the switching control chip 22 sends out an asynchronous message, the main control chip 21 needs to establish a second server and create a second listening port (for example, the port may be defined as 10002), and likewise, the second server supports at least 32 communication connections at the same time.
Further, in this embodiment, the first message, the port configuration message, the port LED status control message, the data stream creation message, the MDU upgrade message, the active partition setting message, the DSCP priority mapping configuration message, the port return status configuration message, the uplink speed limit configuration message, and the downlink speed limit configuration message are asynchronous messages;
the acquisition port state report message, the heartbeat message, the acquisition current active zone message, the 802.1X message control message, the uplink speed limit acquisition message and the downlink speed limit acquisition message are synchronous messages.
When the switching chip 23 receives the second message forwarded by the switching control chip 22, the corresponding communication service operation is executed based on the second message.
For example, when the second message is a port configuration message, the switch chip 23 configures the corresponding port information according to the port configuration message.
The main control chip 21 thus implements management of the switch chip 23, thereby implementing configuration of communication services.
