Transport Profile MPLS-TP Who can benefit?
Some Service Providers are focusing on transporting data (wholesale, SDH migration etc).
Flows are well defined and predictable
IP/MPLS is very flexible – Traffic Engineering could be used.
How it could be done simpler? MPLS-TP is the answer

OAM tools are addedOld, pre-standard based on ITU Y.1731 (T-MPLS, PTN) are not part of IETF
recommendations. IETF experience showing that using different solutions for the same tasks brings more problems.

Carrier Ethernet Virtualization

Virtualization todayPhase 1. Satellites
Virtualization is very “fashionable” word – and very useful
‘Abstract’ from real hardware
Simplifies and reduce costs of operations: Configuration, Maintenance, Upgrades etc.

Service integration. IPv4 to IPv6Carrier Grade NAT (CGN), Large Scale NAT (LSN)
SPs are facing two separate tasks
Introduction of IPv6 – important to introduce because of the future
IPv4 exhaustion – important to keep because of the content in IPv4
Cisco developed IPv6 migration strategyy and CGN solution which could be optimized for specific network design
