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

MPLS-TP in action
 MPLS-TP dedicated session in this EXPO
 Simply it ‘detached’ control plane from IP routing and devices
 Paths provisioned from Centralized NMS
 OAM tools are added
Old, 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.

Current IETF approved based on MPLS OAM extensions

Virtualization today
Phase 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 IPv6
Carrier 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
 High speed data logging

 There are different types of video traffic
 Video traffic is ‘most prominent’
Highest volume
One of the highest SLA requirements (no packet loss)
Design your network for video – rests will be fine 
 Video SLA
Delay/Jitter. QoS design
Throughput. Network capacity planning, local replication and caching
Packet Loss and Service Availability. Protection and recovery.
