MPLS-TP & PTN
MPLS-TP & PTN
MPLS-TP (Multiprotocol Label Switching - Transport Profile) with PTN (Packet Transport Network) is better than IP/ MPLS and costs lower than SDH/ SONET(TDM).
- Electrical sub-station
- Public and Military air
- Rail and road traffic
- Power grids
MPLS-TP, a simplified version of IP/ MPLS, is a variant of the IP/ MPLS protocol issued in 2006 by the IETF together with ITU-T.
MPLS-TP is a type of MPLS that utilizes Tunnel/ Label Switching Path (LSP), controlled and administrated by Network Management System (NMS), to transport services from multiple protocols in a mesh infrastructure without analyzing their contents.
MPLS-TP eliminates the complexity of IP/ MPLS control plane protocol. With bidirectional LSP, MPLS-TP supports deterministic performance bandwidth, latency, jitter, and codirectional transport with synchronization and timing distribution.
As a connection-oriented packet-switched profile, MPLS-TP and the administrator will implement a PseudoWire (PW) and LSP as a circuit with protection for various services, including PDH, SDH, and Ethernet.
The hierarchic OAM (Operation Administration Maintenance) of MPLS-TP functions provide alarm monitoring and signaling, traffic diagnosis, and circuit performance monitoring at every layer (Section, LSP, and PW).
As the figure below shows, OAM can provide quality guarantee and carrier-class protection, which demonstrate reliability for customers.
