Document Type and Number:
WIPO Patent Application WO/2022/001238
Kind Code:
A1
Abstract:
Embodiments of the present application provide a bandwidth scheduling method and system based on a multi-level passive optical network. The method comprises: a first-level optical line terminal receives a first bandwidth request sent by a first-level optical network unit; the first-level optical line terminal sends a first bandwidth size to the first-level optical network unit; the first-level optical line terminal sends a second bandwidth request to a second-level optical line terminal, the data traffic size requested by the first-level optical line terminal comprising part of the data traffic size requested by the first-level optical network unit; and the first-level optical line terminal receives a second bandwidth size sent by the second-level optical line terminal. According to the present application, signaling interaction and data interaction are reduced, the time of allocating bandwidth to the first-level optical line terminal can be accelerated, the delay of bandwidth allocation is reduced, the overall bandwidth allocation delay of the multi-level passive optical network is reduced, and the overall data transmission efficiency of the multi-level passive optical network is improved.
