Wherein, the target grouping mark occupies 16 bytes, namely 2 can be supported in the same local area network¹⁶ And (4) grouping. The protocol type identification occupies 32 bits if the protocol is IPv4 protocol; the protocol type identification occupies 128 bits if the protocol is IPv6 protocol; if the multicast address instep 201 includes only a multicast IP address, the multicast group MAC address corresponding to the multicast IP address may be determined according to a mapping relationship between the multicast IP address and the multicast group MAC address. The checksum may be populated according to a four-layer protocol standard.

It should be noted that the data content may also include a multicast address, a target packet identifier, an operation type identifier, and a protocol type identifier, or the data content includes a multicast address, a target packet identifier, an operation type identifier, and a checksum.

Step 304, the server obtains the group identifier of the server.

The group identifier of the server may be configured in advance, and after the group identifier of the server is configured, the server may obtain the configured group identifier of the server.

Step 305, the server determines whether the server's group identity matches the target group identity.

If the group identifier of the server matches the target group identifier, go to step 306; if the group id of the server does not match the target group id,step 307 is performed.

And step 306, executing the operation corresponding to the operation type identification on the multicast address.

The operation corresponding to the operation type identifier is executed on the multicast address, which can be realized by the following steps:

when the operation type identifier is an addition identifier, performing addition operation corresponding to the addition identifier on the multicast address; or,

and when the operation type identifier is the deletion identifier, executing deletion operation corresponding to the deletion identifier on the multicast address.

It should be noted that the broadcast message may further include a checksum; before the operation corresponding to the operation type identification is executed on the multicast address, the following steps can be further included:

judging whether the received broadcast message is complete according to the checksum, and correspondingly, executing the operation corresponding to the operation type identifier on the multicast address can be realized by the following modes:

and if the received broadcast message is complete, executing the operation corresponding to the operation type identifier on the multicast address.

Step 307, the operation corresponding to the operation type identifier is not performed on the multicast address.

It should be noted that, since the server may receive the broadcast packet sent by the control node, determine whether the packet identifier of the server matches the target packet identifier in the broadcast packet, for example, if the packet identifier of the server matches the target packet identifier, if the operation type identifier is an addition identifier, perform an addition operation corresponding to the addition identifier on the multicast address. If the operation type identifier is a deletion identifier, the deletion operation corresponding to the deletion identifier is executed on the multicast address, so that the control node sends a broadcast message once, and the multicast address of the server can be automatically and quickly added or deleted without manually configuring the multicast address of the server.
