Connection management server, OLT, ONU/ONT and the system and method for providing ethernet-based PTL-PON

摘要

Provided is a passive optical network (PON) providing system of an Ethernet-based packet transport layer (PTL) scheme, including: a connection management server to manage a unified PTL connection overall over the network by establishing a PTL connection between an optical network unit (ONU)/optical network terminal (ONT) of a customer termination of one party and an ONU/ONT of a customer termination of another party, and by applying a PTL-PON scheme to a PON section between the ONU/ONT and an optical line termination (OLT); an OLT to manage a connection of a received packet, and to convert a format of the packet according to a transmission direction of the packet and thereby transmit the packet; and an ONU/ONT becoming an end point of the PTL connection to convert the format of the packet according to the transmission direction of the received packet and to thereby transmit the packet to a customer terminal or the OLT.

主权项

1. An OLT of a PON providing system of an Ethernet-based PTL scheme, wherein the OLT manages a connection of a received packet, and converts a format of the packet according to a transmission direction of the packet and thereby transmits the packet to an ONU/ONT or a packet switch, and
wherein the connection management of the packet is performed by receiving, from a connection management server, a base connection table including information on the packet, by generating a first connection table including identification information of the OLT ports and the ONU/ONT based on the base connection table, by generating a second connection table used by the ONU/ONT based on the first connection table, and by transferring the second connection table to the ONU/ONT.
