Abstract
A method of transmitting an Operations, Administration and Maintenance (OAM) message and of processing an error in a Passive Optical Network (PON) system is provided. Using an OAM packet format that may be used in common in the PON system, a process of transmitting or receiving an OAM message may be simplified, an efficiency of the process may be increased, and an Optical Network Unit (ONU) may be managed at a high speed.
Claims11
A method of transmitting an Operations, Administration and Maintenance (OAM) message in a Passive Optical Network (PON) system, the method comprising:
- transmitting a create OAM message to an Optical Network Unit (ONU);
- and
- receiving a response OAM message from the ONU,
- wherein the create OAM message comprises a message identifier (ID) field, a message contents length field, and a message contents field that are associated with at least one Ethernet switch control creation message, the Ethernet switch control creation message capable of being at least one of a create Gigabit-capable Passive Optical Network Encapsulation Method (GEM) Connection Termination Point (CTP) message, a create Gigabit-capable encapsulation method adaption layer (GAL) Ethernet message, and a create Media Access Control (MAC) bridge service message, and
- wherein the response OAM message comprises a message ID field, a message contents length field, and a message contents field that are associated with at least one Ethernet switch control response message.
A method of transmitting an Operations, Administration and Maintenance (OAM) message in a Passive Optical Network (PON) system, the method comprising:
- receiving a create OAM message from an Optical Line Terminal (OLT);
- and
- transmitting a response OAM message to the OLT,
- wherein the create OAM message comprises a message identifier (ID) field, a message contents length field, and a message contents field that are associated with at least one Ethernet switch control creation message, the Ethernet switch control creation message capable of being at least one of a create Gigabit-capable Passive Optical Network Encapsulation Method (GEM) Connection Termination Point (CTP) message, a create Gigabit-capable encapsulation method adaption layer (GAL) Ethernet message, and a create Media Access Control (MAC) bridge service message, and
- wherein the response OAM message comprises a message ID field, a message contents length field, and a message contents field that are associated with at least one Ethernet switch control response message.
A method of processing an error of an Operations, Administration and Maintenance (OAM) message in a Passive Optical Network (PON) system, the method comprising:
- transmitting an OAM creation message to an Optical Network Unit (ONU), the OAM creation message comprising a plurality of OAM messages;
- receiving an OAM response message from the ONU, when the error occurs in an OAM message among the plurality of OAM messages, the OAM response message being associated with a completely processed OAM message among the plurality of OAM messages and a result of processing the OAM message with the error among the plurality of OAM messages;
- and
- transmitting an OAM creation message to the ONU, the OAM creation message comprising a non-processed OAM message following the OAM message with the error among the plurality of OAM messages.
A method of processing an error of an Operations, Administration and Maintenance (OAM) message in a Passive Optical Network (PON) system, the method comprising:
- receiving an OAM creation message from an Optical Line Terminal (OLT), the OAM creation message comprising a plurality of OAM messages;
- processing the plurality of OAM messages, and when the error occurs in an OAM message among the plurality of OAM messages during the processing, transmitting an OAM response message to the OLT, the OAM response message being associated with a completely processed OAM message among the plurality of OAM messages and a result of processing the OAM message with the error among the plurality of OAM messages;
- receiving an OAM creation message from the OLT, the OAM creation message comprising a non-processed OAM message following the OAM message with the error among the plurality of OAM messages;
- and processing the OAM message with the error and the non-processed OAM message, and transmitting, to the OLT, an OAM response message associated with the processed OAM messages.
