Abstract

Disclosed are a packet transport network troubleshooting method, packet transport network node and packet transport network. The method comprises: a PTN node detects whether a present MPLS outbound route established with other PTN nodes has any problems; if yes, then information of a route-associated protection group where the MPLS outbound route is located is obtained; the PTN node detects whether other outbound routes in an outbound route labeled list of the obtained route-associated protection group all have problems; if yes, then one or more user network edge device CE will be notified of the fault information. The user network edge device CE is connected with the PTN node through an inbound route in an inbound route labeled list of the obtained route-associated protection group, to facilitate the CE in switching present services to other PTN nodes. Embodiments of the present invention can achieve protection of services when problems occur.
