• “Standard Services”– MPLS VPN – Ethernet E-LINE– Ethernet E-LAN– Wholesale Broadband
• Other Services– Mobile (Cellular) Backhaul
• E1, ATM & Ethernet PWE3s– High performance Financial Markets Services– Content Services
• Broadcast Video• CDN, IP (Linear) TV & Canvas
• Converging onto a single Ethernet/MPLS platform– How 21CN underpins Ethernet, Mobile Backhaul, Broadband &
Content services
Describe the diverse range of services that BT supports using Ethernet and MPLS

MPLS VPN
• 172 Countries– >230000 customer ports
• >100000 outside UK– >200 PoPs
• >180 outside UK– Still seeing significant growth
• Market Share (IDC)– UK: 40%– Global: 16%
• Customers include– Large financial institutes
• Some of the world's largest financial market data vendors
• Multiple banks– Public Sector / Government– Transport Industry– Retail & Food Industries– Pharmaceutical Industry
• Hierarchy– Tier 1: Aggregation & Routing– Tier 2: Aggregation & Customer
access– Regional Route Reflectors
• Resilience– Intra & Inter PoP
• Dual Vendor Core– Dual Tier 1 Core– Physical separation
• 6 CoS• Multicast enabled• Future evolution
– Even more Ethernet access– Further NNIs to complement
traditional PoP expansion• Expand in-country coverage
– IPv6

E-LINE & Mobile (Cellular) Backhaul
• Etherflow UK– P2P Service
• VLAN access• Ethernet PWE3 backhaul/core
– >700 PoPs– >100 PoPs of EEA
• Access & Aggregation layer– ~600 PoPs of EES
• Access layer– Port speeds from 10 Mbps to 1 Gig
• Sub rates from 1 Mbps
• Mobile (Cellular) Backhaul– Built on top of Etherflow– E1 & ATM PWE3s
• From base station to mobile switch site– 4 out 5 UK Mobile Operators– Still in deployment
• Contracts total ~20k base stations– Future direction:
• Near term: Ethernet presentation & synchronisation
• Long term: supporting LTE with IP layer & any to any capabilities

• Managed VPLS service covering Spain– First launched in 2004
• Mainly E-LAN Any to Any connectivity– Some E-LINE (P2P) and Hub & Spoke– Access port speeds from 10 Mbps up to 1
Gbps• Mixture of technoogies including EFM
– Access sub-rates from 1 Mbps to 990 Mbps
– 6 CoS• HVPLS implementation.
– Core of 4 nodes in 4 PoPs• Madrid and Barcelona
– 10 VPLS regions covering different geographical areas.
– 46 PoPs covering all 51 provinces.• Including the Canary and Balearic Islands.
– Gateways to• BT MPLS VPN• Internet• Voice Softswitches
E-LAN (VPLS)
• Standalone managed VPLS service covering London
– E-LAN Any to Any connectivity• Access port speeds from 10 Mbps up to 1
Gbps• Access sub-rates from 2 Mbps to 900 Mbps• 2 CoS
– 6 Access PoPs– 2 Core PoPs
• VPLS used for some internal management (DCN) on 21CN
• Planning VPLS for supporting Wholesale IPTV services

“When talking about low latency connectivity to execution venues, no one else compares [to BT].” Bryce Byers – President & CEO, Neovest
Ultra Access voted “Best New Vendor Solution” Financial News, 2007
ULTRA
• Capital markets participants require:
– Fast, direct connectivity to execution venues in major financial markets
– Extremely low, deterministic latency• “Yesterday’s ultra-low latency is merely
today’s low-latency.” Tabb Group– Extremely High SLAs
• ULTRA offers:– Services in New York, Chicago, London– Up to 10 Gbps Access– Deterministic latency & RTD <1 ms– 100% Uptime Guarantee– Fully resilient, non-blocking architecture
• Single Telco hop– Multicast replication– Direct Market Access Speedometer– Network visibility tools– Bandwidth management
“If a broker’s electronic trading platform is 5 milliseconds behind the competition, it could lose at least 1% of its flow; that’s $4 million in revenues per millisecond” Tabb Group
As if the exchange is connected in their basementAlgorithmic trading and direct market access are the biggest disruptors in
modern-day markets
Gone from virtually 0% to 35% of institutional order flow in 5 years.

Media & Broadcast Global MPLS Media Network
• Broadcast applications– Dynamic ‘contribution’– Permanent contribution &
distribution– High priority data
• Non RT programmes, VoIP, CES– Lower priority data
• Broadcast requirements– Low latency, Low Jitter– Zero packet loss– Flexible control path– Bandwidth on demand

Wholesale Content Services
• Wholesale Content Connect (wCC)• Establishing broadband as a
content delivery platform– Reduce impact of OTT content for
ISPs• Insert ISPs into the commercial value
chain for distribution of OTT content over broadband
– Enable ISPs/CSPs to launch Quality Assured content services
• Harnessing QoS & BB to deliver a fantastic content experience for End Users
• Co-locating Content Caches with BB IP Service Edge
– QoS enabled CDN & BB– Distribution via MPLS VPN
• Wholesale IPTV services– VPLS or MPLS VPN
• Future: Move BB IP Service Edge closer to End Users
