Devices produced by the same manufacturer can communicate with each other through private packets, but because of vendor devices. The private message may be modified due to the version upgrade. Therefore, there may be a problem that the new version and the old version of the protocol may not be unified. In addition, if different private protocols are successfully connected to different vendors, it is also necessary to support auto-negotiation of some protocol packets. In addition, although the interaction between most network devices today uses the standard protocol packet format specified in the TCP/IP protocol suite, the padding of each field in the packet will inevitably be somewhat similar. How can it be masked? The difference in the format of the protocol packets of different vendors makes it possible for devices to communicate properly.

In this case, the packet format needs to be adjusted. The format is adjusted to the format of the packet sent by the peer device. Then, the format of the packet sent by the port in the packet format table is updated to the format of the packet sent by the peer device, and then the local device according to the updated packet in the packet format table. The format sends a message.

The packets involved in the foregoing embodiments and embodiments may be packets that are normally communicated. However, in order to not affect the normal communication, in one embodiment, the format of the packets supported by the communication parties may be determined by negotiation. That is, the foregoing packet may be a negotiation packet. When the packet is a negotiation packet, the connection failure may be that the negotiation fails, that is, the negotiation packet sent by the local device is not recognized by the peer device.

The packet format is adjusted according to the foregoing embodiment and the optional implementation manner, and the format of the packet that the local device receives the predetermined protocol on the same port is consistent with the format of the packet that sends the predetermined protocol.

The negotiation packet format is B, and the format of the negotiation packet sent by the port on the device 2 is inconsistent. The global port protocol format table is updated, and the protocol packet format of the port is updated to B.

If the port sends a negotiation packet, the port sends a packet with the corresponding format according to the status flag of the protocol in the global port protocol packet format table. The port directly connected to device 1 receives the negotiation packet format as A. The format of the negotiation packet sent by the port is A. The format of the negotiation packet sent by the port directly connected to device 3 is B. The format of the negotiation packet sent by the port is B.

In the foregoing step b, when the interface directly connected to the device 3 receives the negotiation packet format B, and the format of the negotiation packet currently sent by the port on the device 2 is inconsistent, in the related art, the device 3 and the device 2 are connected. failure. According to the packet format processing method of the embodiment of the present invention, the protocol format table is updated, and the format of the negotiation packet sent by the device directly connected to the device 3 in the device 2 is updated to B, and the port is connected again. The docking was successful.
