WHAT’S THE VALUE OF MPLS-TP FOR UTILITY NETWORKS?

How


MPLS-TP VALUE FOR UTILITIES NETWORKS

Maintains TDM like predictable and deterministic performance over packet infrastructure



Critical for low latency, low jitter and accurate timing

Must have for mission critical applications like Teleprotection and synchronization

Risk free transition to packet

MPLS-TP(MPLS TRANSPORT PROFILE)


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)


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

DISCARDED ADDEDKEPT

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

Customer Edge (CE)

Customer equipment

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


Discarded


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


DISCARDED ADDEDKEPT

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

CONTROL PLANE


MANAGEMENT/CONTROL & DATA PLANE SEPARATION

IP/MPLS – No separation between control and data planes MPLS-TP – Control plane is totally separated from the data plane

Control Plane

Data Plane

Value for Utilities:Better stability and security - any failure in Management / control plane will not impact the traffic


OAM(OPERATION ADMINISTRATION AND MAINTENANCE)


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

Data Plane

G-Ach for OAM

Value for Utilities:In band OAM ensures transport like operation meeting connection oriented concept

Proactive monitoring triggers fast switch to protection and faster troubleshooting, making network performance predictable


PROTECTION


GUARANTEED <50MSEC SWITCH TO PROTECTION IP/MPLS – Cannot guarantee sub-50 millisecond

convergence for any topology MPLS-TP – guaranteed sub-50 msec switch to protection
