IP Transformation – A Definition
What? Service providers evolve their people, process and tech
nology to leveragea single, converged network on IP.
Why? Enable greater efficiencies, lower costs, and create new revenue streams
from profitable IP-based services.
How?Network IP transformation Multi-purpose converged IP infrastructure
Service IP Transformation Connectivity-centric to service-centric
Organization IP Transformation Internal changes in sync with network IP transformation
External partnerships for service IP transformation

Ethernet as Access
Ethernet is the easiest access technology
Plug-and-play, auto-discovery
Ease of administration and internetworking
Port speed from 10 Mbps to 10 Gbps
Perceived as high-speed, low-cost
Little need for in-house IT support with advanced datacommunication experience
Ethernet is the ideal networking technology for office environment.Ethernet is the ideal networking technology for office environment.

Non-carrier Grade Ethernet Solution
The metro Ethernet services (MES) being deployed by serviceproviders today have significant limitations.
Poor QoS for multi-service over shared media - the only way tominimized packet loss, jitter and delay is to overprovision
Extremely limited service portfolio – best effort only
Poor VPN scalability – 4k VLAN IDs per network
Poor network resiliency – Spanning Tree Protocol is very slow fornetwork re-convergence upon network failure
Lack of OAM capabilities for service assurance
Lack of accounting capabilities for revenue generation
From a carrier’s point of view, Ethernet is not yet ready for the “ primetime ”From a carrier’s point of view, Ethernet is not yet ready for the “ primetime ”

MPLS-based Ethernet
Equipment vendors patch their products to introduce MPLS-
based Ethernet service to achieve: Better QoS based on MPLS forwarding classes
Expanded service portfolio (Layer 2 and Layer 3 VPNs)
Better scalability – VLAN IDs should have only local significance
Better network resiliency – MPLS Fast Reroute (FRR) Better OAM capabilities – LSP ping and traceroute
Better accounting – connection-oriented packet counting
MPLS makes Ethernet a credible carrier service.MPLS makes Ethernet a credible carrier service.
Better = varying degree of improvement

Guaranteed QoS for multi-service

Today ’s IP network is used to provide:
(unprofitable) Internet access and routing
Limited IP/VPN due to weak service QoS and service scalability

•Leased lines•Mostly narrowband•High OPEX due tomanagement
•Perceived as “old”
• Ethernet VPNs• Poor scalability
• Poor QoS• High OPEX due to VLAN

un-realiable”
• High-speed Internet Access• BRAS model limits tripe-play

Addressing the MSE market segment
Consolidated IP edge service delivery platform
Broad range of L2 and L3 services
E.g. FR, Ethernet, ATM and TDM along with IP VPNs
Single core network layer: most commonly MPLS
Primary Drivers
Minimise the cost/risk associated with rolling out newservices: avoid building a new network for each newservice
Generate new revenues from new wide area Ethernetservices (VLL/VPLS) and 2547 IP-VPN
Extend reach of existing Ethernet/FR/ATM services out-of-
region sites Part of a wider IP convergence strategy - next generation
mobile backhaul and residential 3-play
Reduce CAPEX and OPEX
Complete replacement of allpublic networks, driven by PSTN
end of life. Estimated £1B inOPEX savings
Expansion of metro networks withadditional cost savings managing
existing FR / ATM services
Backhauling ATM traffic to anMPLS core
