Abstract
Official abstract text for this publication.
A method for upstream bandwidth allocation in a passive optical network is provided by the disclosure. The method includes the following steps: an Optical Line Terminal (OLT) allocates an upstream bandwidth for an Optical Network Unit (ONU) through an upstream bandwidth mapping (US BWmap) domain, wherein the total length B of payloads transmitted by consecutive Transmission Containers (T-CONTs) allocated for the ONU is: the product of the positive integer n and the data byte length L contained in a code word when the ONU uses Forward Error Correction (FEC) encoding, minus the byte length R of the contents protected by FEC, except the payloads, in an upstream burst slot transmitted by the ONU, i.e. B=L×n−R bytes ( 401 ); and the ONU encapsulates the upstream data according to the size of the T-CONT total bandwidth allocated by the OLT and transmits it to the OLT ( 402 ). A system for upstream bandwidth allocation in a passive optical network is also provided by the disclosure. Application of the disclosure reduces the complexity of processing FEC-encoded data by the ONU and the OLT, and improves the encoding efficiency of the ONU and the decoding efficiency of the OLT.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for upstream bandwidth allocation in a Passive Optical Network (PON), comprising: allocating, by an Optical Line Terminal (OLT), an upstream bandwidth for an Optical Network Unit (ONU) through an Upstream Bandwidth Map (US BWmap) domain in terms of a total length B of payloads transmitted by consecutive Transmission Containers (T-CONTs) allocated for the ONU, wherein B is the product of a positive integer n and a byte length L of data containe…
