MPLS-TP(MPLS TRANSPORT PROFILE)
ECI Telecom Proprietary and Confidential 20ECI Proprietary 20
MPLS-TP OBJECTIVES “To enable MPLS to be deployed in a
transport network and operated in a similar manner to existing transport technologies (SDH/SONET/OTN)”
“To enable MPLS to support packet transport services with a similar degree of predictability, reliability, and OAM to that found in existing transport networks”
Defined jointly by IETF and ITU-T
(MPLS Transport Profile Framework)
ECI Telecom Proprietary and Confidential 21ECI Proprietary 21
MPLS-TP MPLS TP is both a subset and an
extension of IP/MPLS to meet transport requirements
Kept – Packet forwarding Discarded – Features that hurt
deterministic performance or that are not connection oriented
Added – Transport like OAM, protection, operation

LABEL-SWITCHINGA path from source to destination
is determined and a “label” is applied to it
NEs Along the path, use the label to forward the traffic without any additional IP lookups
Value for Utilities: Deterministic performance –
path is known and fixed

Label Switched Path (LSP) A unidirectional network wide tunnel between source and destination routers
Label Edge Router (“LER”) – Ingress Node. The router which adds the MPLS label
Label Edge Router (“LER”) – Egress Node. The final router at the end of an LSP, which removes the label
Label Switching Router (“LSR”) - Transit node. Does only label switching in the middle of an LSP

DISCARDED ADDEDKEPT
NON DETERMINISTIC FEATURES PHP - removes the MPLS label one node before the egress node
Makes protection and OAM functions invalid Assumes traffic is IP
LSP Merge - merging two or more LSPs (going to the same destination) to use the same MPLS label
Source information is lost, preventing original LSPs to be monitored ECMP - split traffic within the same LSP over multiple LSPs that
have equal cost Different packets from the same LSP take different paths – not
connection oriented

CONTROL PLANE IP/MPLS – strictly dependent upon control plane protocols MPLS-TP – does not require any control plane protocols
Value for Utilities:Full visibility and control over the network at any given timeReducing OPEX and CAPEX and scale easily – no distributed complex protocolsEliminating recruiting of new personal - working procedures similar to TDM

BI-DIRECTIONAL LSP
IP/MPLS - uses Uni-directional LSPs – traffic from A to B can flow over different paths than traffic from B to A
MPLS-TP - uses bi-directional LSPs – traffic on both directions traverse exactly the same path

PROACTIVE IN-BAND OAM IP/MPLS – OAM info is carried out of band. Might not take the same
path as data traffic MPLS-TP - OAM is carried with the user traffic inside the MPLS-TP
frame and is proactiveMPLS-TPIP/MPLS
