US 2014/0178074 A1 · METHOD FOR ACQUIRING PON PORT ASSOCIATION RELATIONSHIP, OPTICAL NETWORK DEVICE, AND OPTICAL NETWORK SYSTEM

Abstract

The present invention discloses a method for acquiring a PON port association relationship. An OLT where a standby PON port is located receives a protection packet from an optical network unit, parses the protection packet to obtain an identifier of an active PON port carried in the packet, and acquires an association relationship between the active PON port and the standby PON port according to an identifier of the standby PON port receiving the protection packet. When the present invention is implemented, the OLT where the standby PON port is located can acquire an association relationship between an active PON port and a standby PON port, and determine, according to the association relationship, whether the protection packet is valid or acquire, according to the association relationship, configuration information of the active PON port.

Dependent claims

A method for obtaining a PON port mapping relationship, comprising:

receiving, through a standby PON port, a protection packet that carries a port identifier of active PON port from an optical network unit ONU;
parsing the protection packet to obtain the port identifier of the active PON port carried in the protection packet;
and
acquiring an association relationship between the standby PON port and the active PON port according to a port identifier of the standby PON port receiving the protection packet.

1 more element

An optical network device, comprising:

a receiver, configured to receive, through a standby PON port, a protection packet that carries a port identifier of an active PON port from an optical network unit ONU;
a parsing unit, configured to parse the protection packet received by the receiver to obtain the port identifier of the active PON port carried in the protection packet;
and
an acquiring unit, configured to acquire an association relationship between the active PON port and the standby PON port according to a port identifier of the standby PON port receiving the protection packet.

1 more element

An optical network system, comprising an optical network unit ONU and a first optical line terminal OLT, wherein:

the ONU is configured to send a protection packet that carries a port identifier of an active PON port to the first OLT;
and
the first OLT is configured to receive the protection packet through a standby PON port, parse the protection packet to obtain the port identifier of the active PON port carried in the protection packet, and acquire an association relationship between the active PON port and the standby PON port according to the port identifier of the standby PON port receiving the protection packet.
