Abstract
Methods for increasing upstream bandwidth utilization in an Ethernet passive optical network (EPON) use in some instances round-down instead of round-up occupancy values reported to an optical line terminal. An optical network unit determines whether the occupancy needs to be round-up or round-down and reports the occupancy in either round-up or round-down report units to the optical network terminal.

A method for increasing upstream bandwidth utilization in an Ethernet passive optical network (EPON), comprising the steps of:
- by an optical network unit (ONU) having queues with occupancy levels:
- a) determining whether a queue occupancy needs to be round-up or can be round-down;
- and
- b) based on the results of the determination, reporting the queue occupancy in either a rounded-up or rounded-down report value to an optical network terminal (OLT) of the EPON.
A method for increasing upstream bandwidth utilization in an Ethernet passive optical network (EPON), comprising the steps of:
- by an optical network unit (ONU) having an occupancy:
- a) checking if the occupancy can be round-down to a first report value, and if yes;
- b) rounding-down the occupancy to the nearest time quanta (TQ) units to obtain the first report value;
- and
- c) reporting the first report value to an optical network terminal (OLT) of the EPON.

- a) checking if the occupancy can be round-down to a first report value, and if yes;
- b) rounding-down the occupancy to the nearest time quanta (TQ) units to obtain the first report value;
- c) checking if the first report value is smaller than five TQs and if yes,
- d) rounding-up the occupancy to the nearest TQ units to obtain a second report value;
- and
- e) reporting the second report value to an optical network terminal (OLT) of the EPON.
