Title:
ACCURATE REPORTING MECHANISM FOR BANDWIDTH REQUIREMENTS OF OPTICAL NETWORK UNIT
Document Type and Number:
WIPO Patent Application WO/2024/031206
Kind Code:
A1
Abstract:
Disclosed in the present invention is an accurate reporting mechanism for a bandwidth requirement of each priority queue of an optical network unit in a passive optical network communication system. In the present invention, defects of existing passive optical network protocols in an optical network unit bandwidth requirement reporting mechanism are first analyzed, and it is proposed that an optical line terminal needs to be prevented from remotely estimating the bandwidth requirements of the optical network unit. In the new reporting mechanism, the amount of data received by the input port of a buffer within a period of time instead of the amount of buffer data at a certain moment is reported by the optical network unit, and reported information contains payload and corresponding overhead. After such an improvement, the optical network unit no longer needs to send an idle frame to the optical line terminal, thereby achieving 100% effective utilization of an uplink bandwidth. In addition, the reporting mechanism performs reporting at the entrance of the buffer instead of performing reporting after an uncertain delay after the payload has entered the buffer, and therefore, compared with implementation methods proposed based on the existing passive optical network protocols, the method provided by the present invention can achieve the smallest possible and more stable delay. FIG. 2 is the drawing of the abstract of the present invention.
