Troubleshooting method, aggregation node, and optical network protection system
First Claim
1. A troubleshooting method, comprising:
- determining, by an aggregation node when a link fault or a device fault occurs on an active optical line termination OLT side, an active logical port used by the active OLT to forward a data packet, wherein the active logical port supports at least one user service, and each user service is denoted by a user service identifier (C-VLAN, S-VLAN) formed by a user local area network tag C-VLAN and a service local area network tag S-VLAN;
searching, by the aggregation node, a locally stored logical port mapping table according to the active logical port to obtain a standby logical port corresponding to the active logical port, wherein the standby logical port supports a same user service as the active logical port; and
triggering, by the aggregation node, the standby OLT to enable the standby logical port to receive a data packet that is sent by the standby OLT through the standby logical port.

Abstract
Embodiments of the present invention disclose a troubleshooting method. The method includes: determining, by an aggregation node when a link fault or a device fault occurs on an OLT side, an active logical port used by the active OLT to forward a data packet; searching, by the aggregation node, a locally stored logical port mapping table according to the active logical port to obtain a standby logical port corresponding to the active logical port, where the standby logical port supports a same user service as the active logical port; and triggering, by the aggregation node, the standby OLT to enable the standby logical port to receive a data packet that is sent by the standby OLT through the standby logical port. The implementation of the present invention can provide utmost compatibility with the live network and enable a communication link to recover from a fault quickly.

6. An aggregation node, comprising:
-
a memory, configured to store a table of mapping between logical ports of an active optical line termination OLT and a standby OLT; a port determining unit, configured to;
when a link fault or a device fault occurs on an active OLT side, determine an active logical port used by the active OLT to forward a data packet, wherein the active logical port supports at least one user service, and each user service is denoted by a user service identifier (C-VLAN, S-VLAN) formed by a user local area network tag C-VLAN and a service local area network tag S-VLAN;a mapping searching unit, configured to search, according to the active logical port determined by the port determining unit, the logical port mapping table stored in the memory to obtain a standby logical port corresponding to the active logical port, wherein the standby logical port supports a same user service as the active logical port; and a port enabling unit, configured to trigger the standby OLT to enable the standby logical port to receive a data packet that is sent by the standby OLT through the standby logical port. - View Dependent Claims (7, 8, 9)

10. An optical network protection system, comprising:
-
an aggregation node, and at least one active optical line termination OLT and at least one standby OLT that are connected with the aggregation node, wherein the aggregation node is configured to;
when a link fault or a device fault occurs on an active OLT side, determine an active logical port used by the active OLT to forward a data packet, wherein the active logical port supports at least one user service, and each user service is denoted by a user service identifier (C-VLAN, S-VLAN) formed by a user local area network tag C-VLAN and a service local area network tag S-VLAN;
search a locally stored logical port mapping table according to the active logical port to obtain a standby logical port corresponding to the active logical port, wherein the standby logical port supports a same user service as the active logical port; and
trigger the standby OLT to enable the standby logical port to receive a data packet that is sent by the standby OLT through the standby logical port.
