MPLS_TP is a protocol similar to IP MpLS and designed for transport networks
-
TP means transport profile , so it can work with multiple types of traffic protocols
-
MPLS TP implemented on Ethernet ports in WDM equipments
-
MPLS TP protection is bidirectional 1:1 LSP
-
Similar to SNCP , protection can be through another backup route
-
We can configure protection to be revertive and non revertive
-
Protection switching time should be less than 50 m sec
-
In revertive mode , we can control the WTR ( wait to restore )
-
IEEE 802.1ag is the OAM message protocol that’s used for control and maintain the WDM Ethernet Links
-
Features and messages included inside the OAM as follow :
-
Continuity check message
-
Loopback message
3-. Link Trace message
-
Alarm indication signal
-
Remote defect indication
These messages will be explained in details later.
