The adjustment module is configured to:

Adding network address data of the optical network unit to the multicast member list, if the multicast join message data meets the multicast join protocol;

Obtaining a multicast data transmission bandwidth by using the multicast data transmission bandwidth configuration data, calculating a difference between the unicast data transmission bandwidth and the multicast data transmission bandwidth, adjusting the unicast data transmission bandwidth, and allocating the The multicast data transmission bandwidth is used to transmit multicast data.
The apparatus for uniformly managing bandwidth of a passive optical network terminal according to claim 7, wherein if the request data is multicast leave message data, the determining module is configured to:

Obtaining a preset multicast leaving protocol, where the multicast leaving protocol includes a multicast member list;

Assessing the request data, determining whether the multicast leaving message data conforms to the multicast leaving protocol;

The adjustment module is configured to:

If the multicast leaving message data conforms to the multicast leaving protocol, deleting network address data of the optical network unit in the multicast member list;

And obtaining, by the multicast data transmission bandwidth configuration data, a multicast data transmission bandwidth, recovering the unicast data transmission bandwidth as an initial bandwidth of the unicast data, and zeroing the multicast data transmission bandwidth.
