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

Network and Service Management

recommendations. IETF experience showing that using different solutions for the same tasks brings more problems.

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.

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
