Method, apparatus, and system for managing label of access network

A non-transitory computer readable medium including computer-executable instructions for execution on an Optical Line Terminal (OLT), such that when the computer-executable instructions are executed by the apparatus a method is carried out comprising:

• allocating a Pseudo Wire (PW) label of an access segment PW for a first port of an Optical Network Unit (ONU) having at least two ports;
• establishing a corresponding relationship between an identifier of the first port of the at least two ports and the PW label;
• carrying the corresponding relationship between the identifier of the first port of the at least two ports and the PW label in a label management message;
• sending the label management message to the ONU wherein the label management message adopts an access network management protocol;
• and
• receiving a frame from the ONU, wherein the frame is encapsulated with the PW label.

A non-transitory computer readable medium including computer-executable instructions for execution on an Optical Network Unit (ONU), such that when the computer-executable instructions are executed by the apparatus a method is carried out comprising:

• sending a label request to an Optical Line Terminal (OLT), wherein the label request carries an identifier of a port of the ONU;
• receiving a response comprising a correspondence between the identifier and a psudeowire (PW) label;
• storing the correspondence in the ONU;
• encapsulating received data into a frame by adding the PW label to the data;
• and
• sending the frame to the OLT.

A method for managing a label, comprising:

• sending, by an Optical Network Unit (ONU), a label request to an Optical Line Terminal (OLT), wherein the label request carries an identifier of a port of the ONU;
• receiving by the ONU, a response comprising a correspondence between the identifier and a psudeowire (PW) label;
• storing, by the ONU, the correspondence in the ONU;
• encapsulating, by the ONU, received data into a frame by adding the PW label to the data;
• and
• sending, by the ONU, the frame to the OLT.
