S201: when pseudo-circuit warp is switched to described pseudo-thread path for subsequent use from primary pseudo-thread path, then SPE1 sends the routing information of described pseudo-thread path for subsequent use to UPE1;
Further, in the present embodiment, label mapping (label mapping) message of carrying the routing information of described pseudo-thread path for subsequent use can be sent to UPE1;
In the present embodiment, the form of the existing label mapping message shown in table 1 can be used to UPE1 to send the label mapping message of carrying the routing information of described backup path.
Table 1
Wherein, the routing information in 0x01 type Data Units and 0x04 type Data Units carrying about standby path is used.
The label mapping message of the routing information of described backup path is carried described in S202:UPE1 receives;
The routing information of for subsequent use pseudo-thread path carried in 0x01 type Data Units and 0x04 type Data Units is replaced the routing information stored by S203:UPE1.
That is: the routing information of the primary pseudo-thread path stored is updated to the routing information of pseudo-thread path for subsequent use.
In the present embodiment, after the pseudo-thread path of current use changes, the routing information of the pseudo-thread path of current use is sent to user-end provider edge by SPE equipment, when user-end provider edge uses two-way converting to detect (Bi-direction Forwarding Detection, BFD), multiprotocol label switching transmission specification operation management (Multiprotocol Label Switching Transport Profile Operation Administrationand Maintenance, MPLS-TP OAM) etc. application time, life span (the Time to Live in the path of current use can be calculated according to routing information, TTL), for BFD, the application such as MPLS-TP OAM.
Visible, method described in the present embodiment, when pseudo-thread path changes, the routing information of the pseudo-thread path after change can be sent to user-end provider edge by SPE equipment in time again, thus ensure that user-end provider edge can normally run BFD, MPLS-TP OAM etc., and SPE equipment is same as the prior art to the process of user-end provider edge transmit path information, do not relate to the change of label mapping message packet form, be easy to realize.
The embodiment of the present invention another routing information disclosed sends and storage means, be applied to following scene: as shown in Figure 1, SPE1 receives the routing information of the primary pseudo-thread path that UPE2 sends, the routing information of described primary pseudo-thread path is sent to UPE1, UPE1 preserves the routing information of described primary pseudo-thread path, and SPE1 receives again the routing information of for subsequent use pseudo-thread path that SPE2 sends.
