AI Technical Summary

Technical Problem

In existing PON networks, the fixed period and fixed length of the discovery window parameters of OLT devices cannot adapt to the conflict requirements of different scenarios, resulting in problems such as delayed registration of new ONUs, low bandwidth utilization, and high probability of conflict.

Method used

By introducing a collision index (CI) calculation formula into the OLT device, the window period and window length of the discovery window are dynamically adjusted, and adaptive adjustment is achieved by combining the weight values ​​of delimiter errors and CRC check errors.

Benefits of technology

It improves the efficiency of batch registration of ONUs, optimizes bandwidth resource utilization, reduces the latency and probability of conflict in new ONU registration, and adapts to different network characteristics and business scenarios.

Abstract

The invention provides a method and equipment for adaptively adjusting parameters of a discovery window of a passive optical network. The method comprises the steps of opening a current discovery window based on a current window period; performing delimiter error detection and cyclic redundancy check error detection on each received registration request message within the current window length of the current discovery window; counting the total number of delimiter errors and the total number of cyclic redundancy check errors detected in the current window length; calculating a conflict index CI corresponding to the current window period and the current window length based on a conflict index calculation formula; and adaptively adjusting the window period and / or the window length of the next discovery window based on the conflict index.
