Method and apparatus for optical network unit ONU overall rate limiting
Embodiments of the present disclosure provide a method and a device for ONU overall rate limiting. The method includes: receiving a multicast program sent by a multicast program server; making N+M copies of the multicast program; sending N copies of the multicast program to N passive optical network PON ports that request the multicast program on demand; and sending M copies of the multicast program to M ONU rate limiting units corresponding to M ONUs that request the multicast program on demand, discarding the M copies of the multicast program. In the method, after the rate limiting is performed on the multicast program, the multicast program is discarded, so that real-time rate limiting is performed on each ONU without affecting bandwidth of a PON.
