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.

A drawing of the first Ethernet system by Bob Metcalfe .

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

 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
