Embodiment Construction

[0037] Functional Overview

[0038] Considering that the IPACT algorithm in the related art cannot obtain the traffic transmitted from the client to the TCONT and cannot accurately estimate the overhead of the upstream traffic, the embodiment of the present invention provides a bandwidth allocation scheme. The processing principle of the scheme is as follows: Estimate the input flow of ONU according to the information; set the input flow jump signal, wherein the input flow jump signal is used to indicate the change of the input flow of two adjacent DBA cycles of the ONU; according to the input flow and the input flow jump signal, the ONU Allocate bandwidth. Through this scheme, a DBA including DBRU report-based dynamic bandwidth allocation (StatusReporting DBA, referred to as SR-DBA) and non-DBRU-based dynamic bandwidth allocation (Non-Status Reporting DBA, referred to as NSR-DBA) algorithms is provided. The overall architecture solves the defects of the IPACT algorithm and a...

Abstract

The present invention discloses a bandwidth allocation method and an optical line terminal (OLT). This method is used for the OLT to allocate bandwidth to an optical network unit (ONU) and includes: estimating input traffic of the ONU according to information from the ONU (S302); setting an input traffic transition signal (S304), wherein the input traffic transition signal is used for indicating a change of the input traffic of two adjacent dynamic bandwidth allocation DBA cycles of the ONU; and allocating the bandwidth to the ONU according to the input traffic of the ONU and the input traffic transition signal (S306). With the present invention, a steady bandwidth allocation, a good transmission delay and a sufficient use of uplink bandwidth are obtained.

Description

technical field [0001] The invention relates to the communication field, in particular to a bandwidth allocation method and an optical fiber line terminal. Background technique [0002] Gigabit Passive Optical Network (GPON) is one of the passive optical networks stipulated by International Telecommunications Union-Telecommunications standardization sector (ITU-T) G.984 Communication protocol, GPON adopts a point-to-multipoint topology. figure 1 It is a schematic diagram of the topology of the GPON network according to related technologies, such as figure 1 As shown, an optical line terminal (Optical Line Terminal, referred to as OLT) 101 is a main node, which is connected to many optical network units (Optical Network Unit, referred to as ONU), for example, ONU 103, ONU 104, ONU 105, These ONUs are slave nodes, and each ONU includes one or more transport containers (Transport Container, referred to as TCONT), for example, TCONT1 to 4, and these TCONT report message (Dynam...
