Patent ID: 8781323

Claim:
A method for a packet transport layer (PTL) connection server to provide a passive optical network (PON) of a PTL, the PTL connection server being connected directly to an optical line termination device (OLT) and PTL switches, connected indirectly to an optical network terminal or optical network unit (ONT/ONU) of a subscriber end, and setting connections, comprising: managing to transmit/receive PTL-PON packets between an ONT/ONU of the subscriber end and an OLT; and setting the ONT/ONU of the subscriber end to be an end point of a PTL connection, wherein the setting of the ONT/ONU of the subscriber end to be an end point of the PTL connection includes: setting a channel from the ONT/ONU of the subscriber end to another ONT/ONU of the opposite side of the subscriber end through the OLT and the PTL switches for transporting the packets as the PTL channel in an access, a metro, and a core networks; bundling a plurality of set PTL channels to be a PTL path in a metro network and a core network; and managing the connection states of intervals through the set PTL channel and the PTL path.
