802.3av compliant method using small timescale bandwidth assignment for increased ONU downstream energy efficiency

摘要

A method for small scale time increased bandwidth assignment to increase optical network unit ONU downstream energy efficiency includes splitting of downstream scheduling cycles into multiple rounds, using selective ones of the multiple rounds as probing rounds and other than said selective ones of the multiple rounds as fixed rounds, the probing rounds and fixed rounds being cooperatively selected for energy efficiency without limitations in length of the downstream scheduling cycles.

1. A method for small scale time increased bandwidth assignment to increase optical network unit ONU downstream energy efficiency, said method comprising the steps of:
a. splitting of downstream scheduling cycles into multiple rounds at an optical line terminal (OLT), comprising:
i) splitting each downstream scheduling cycle into one probing round followed by fixed rounds, splitting a grant calculated from a whole scheduling cycle k into R equal parts and sending the calculated grant in R rounds and regular intervals; and b. using selected ones of said multiple rounds as probing rounds and other than said selected ones of said multiple rounds as fixed rounds, said probing rounds and fixed rounds being cooperatively selected for energy efficiency without limitations in length of said downstream scheduling cycles, wherein said probing rounds represent a transmission, to ONUs in a network, of information comprising a respective transmission duration and interval between consecutive transmissions for each ONU.
