Problems solved by technology
[0006] However, because the RSVP protocol is complex to implement and relies on routing tables, it requires strong processing capabilities of system equipment, while the processing capabilities of ONT, ONU, and OLT do not meet the requirements.
In addition, RSVP is based on an end-to-end signaling protocol. It is necessary to reserve resource soft state information for each flow at each transit node in the path, and to refresh these information regularly, resulting in storage overhead and communication. overhead
Finally, due to the scalability problem of RSVP itself, it also causes problems for the compatibility and expansion of the protocol by different manufacturers.

The invention provides a QoS parameter configuration method in an Ethernet passive optical network. QoS parameters are configured on an optical line terminal; subsequently, an optical network unit and an optical network unit carry out selective configuration according to the QoS parameters and transmit the configuration results to the optical line terminal which adjusts the QoS parameters subsequently according to the configuration results. The method adopts simple protocol to realize the consistent configuration on the QoS parameters of OLT, ONU and ONT (optical network terminals), simplifies the negotiation mechanism of the QoS, meets the processing capability and characteristics of all equipments as much as possible, and improves the interoperability of the QoS in the equipment, thus providing better service quality for the user.
Description
technical field [0001] The invention relates to an Ethernet passive optical network, in particular to a method for configuring service quality parameters in an Ethernet passive optical network. Background technique [0002] Ethernet Passive Optical Network (EPON) is a single-fiber bidirectional optical access network using a point-to-multipoint (P2MP) structure, and its typical topology is a tree. The EPON system consists of an optical line terminal (OLT) on the network side, an optical network unit (ONU) on the user side, and an optical distribution network (ODN). It is a fiber optic bidirectional system. In the downlink direction (OLT to ONU), the signal sent by the OLT reaches each ONU through the ODN. In the upstream direction (ONU to OLT), the signal sent by the ONU will only reach the OLT, and will not reach other ONUs. In order to avoid data conflicts and improve network utilization, the uplink adopts TDMA multiple access mode and arbitrates the data transmission of...
