DYNAMIC BANDWIDTH ASSIGNMENT METHOD AND APPARATUS ON PASSIVE OPTICAL NETWORK

摘要

The present invention discloses a dynamic bandwidth assignment method and apparatus on a PON, where the method includes: determining length information of at least one data packet in a cache queue of a T-CONT; determining, according to the length information of the at least one data packet, a total length of at least one GEM frame that is corresponding to the at least one data packet and is obtained when the at least one data packet is separately encapsulated into a GEM frame; and sending a DBRu to an OLT according to the total length of the at least one GEM frame, so that the OLT assigns bandwidth to the T-CONT according to the DBRu. According to the dynamic bandwidth assignment method and apparatus in the embodiments of the present invention, bandwidth of a system can be saved, and overall performance of the system can be improved.

主权项

1. A dynamic bandwidth assignment method in a passive optical network (PON) comprising:
determining length information of at least one data packet in a cache queue of a transmission container (T-CONT); determining, according to the length information of the at least one data packet, a total length of at least one gigabit passive optical network encapsulation method (GEM) frame that corresponds to the at least one data packet and is obtained when the at least one data packet is separately encapsulated into a (GEM) frame; and sending an uplink dynamic bandwidth report unit (DBRu) to an optical line terminal (OLT) according to the total length of the at least one GEM frame, to enable the OLT to assign bandwidth to the T-CONT according to the DBRu.
