Introduction to Ethernet services over T-MPLS

o Transport MPLS has been defined by ITU-T as an application of the MPLS technology for packet transport networks.
o Ethernet services have been defined by G.8111.x ITU-T Recommendation series as well as by MEF Technical Specification
-> Ethernet services are defined irrespectively on the transport network technology that is used to support them
o Transport MPLS is a packet-based transport network technology well suited to support Ethernet serviceso Transport MPLS has been defined by ITU-T asan application of the MPLS technology forpacket transport networks.

o Transport MPLS has been defined by ITU-T as an application of the MPLS technology for packet transport networks.
o Ethernet services have been defined by G.8111.x ITU-T Recommendation series as well as by MEF Technical Specification
• Ethernet services are defined irrespectively on the transport network technology that is used to support them
o Transport MPLS is a packet-based transport network technology well suited to support Ethernet services
oTransport MPLS networks can be used to implement the following services:
• Point-to-point EPL/EVPL based on MEF E-Line (point-topoint EVC)
• Multipoint EVPLAN (Ethernet Virtual Private LAN) based on MEF E-LAN (multipoint EVC)
• Rooted multipoint Services based on MEF rooted multipoint EVC
oThe implementation of Ethernet services with TMPLS benefit from the Transport MPLS of being both
• a packet technology (i.e. better fitting the nature of packet services like Ethernet)
• a transport technology (i.e. a carrier-grade technology supporting OAM and protection switching capabilities).
Point-to-point EVC over T-MPLS (PW Application)
Pseudowire is traffic  for ethernet service on T-MPLS we will have different QOS (Quality of Service)
PW architecture defined in RFC3985
PW application in T-MPLS networks defined in appendix I/G.8110
PW Application in T-MPLS (Appendix I/G.8110.1)
PW over SDH in T-MPLS (Appendix I/G.8110.1)
Multipoint EVC over T-MPLS
MP EVC over Multicast T-MPLS
R-MP EVC over T-MPLS
Ethernet Services over Multi-domain T-MPLS Networks

o T-MPLS is designed to be a scalable end-to end

packet transport technology

o T-MPLS supports network partitioning

• Network partitioning at the PW level is

supported in line with the multi-segment PW

architecture (draft-ietf-pwe3-
ms-pw-arch-

00.txt)

o T-MPLS supports sub-layer hierarchy
