  3. Agenda

  4. Objectives of the day • The objectives of today are to: • Provide details of the N3 broadband migration • Present a product overview of IPstream • Outline the network migration strategy • Provide an opportunity for questions and answers • Outline the customer order process

  5. N3 Broadband Migration – Context Len Chard NHS CFH

  6. Context for change • N3 Live for 4 years • New Catalogue Services added • Full Catalogue refresh • Individual site migration activity • First new technology with mass applicability • Performance and cost improvements • Unprecedented in life of N3 or NHS Net! • Benefits significant proportion of the estate (c. 12,000 sites)

  7. N3 ADSL Configuration Datastream CAL Primary via IPstream Max Premium • Re-used :- • N3 Customer Router • PSTN Line • ISDN • Only the ADSL • Service is changed Primary via Fixed Rate Datastream N3 Core Network DSL Network IPstream Central Backup via ISDN ISDN N3 Customer Router Local Network

  8. Characteristics of IPstream • Rate Adaptive – variable bandwidth • Shared with non NHS, including domestic use • QoS ‘marked’ but not ‘policed’ end to end • N3SP currently do not consider it suitable for voice • More cost effective than Datastream • Capabilities and performance proven with extended trial • More resilient than Datastream • Failover capability in ‘core’ through use of ‘BT Central’ • Does not use CALs (aggregation points) • IPstream has upgrade path into 21CN product set

  9. IPstream Trial • 45 Sites – geographically dispersed*, chosen to represent different aspects of NHS ADSL sites • Sites migrated using a new PSTN and IPstream service, which would differ from mass migration • Remote migration was not tested in the trial • Sites were surveyed before and after the new service for user perception of performance • In addition speed tests have been done at several sites and probes installed * Dorset, Leicestershire, Surrey and London

  10. Profile of Trial Sites • All formerly 1Mb/s ADSL services* • 29 EMIS LV, 3 EMIS PCS, 5 Vision, 3 iSoft Synergy, 5 Mental Health • 26 Main GP sites, 14 Branch • Variety of VPN configurations * Except 5 Mental Health sites with no previous N3 connection

  11. Customer Perception Feedback • 45 questionnaires returned (from 40 sites) • 35 perceived either an ‘improvement’ or ‘no change’ • 5 perceived deterioration * • 5 questionnaires returned from new sites • All of them satisfied/extremely satisfied with service * All were associated with issues not related to IPstream

  12. Network Setup Results • Maximum Stable Rate (MSR) • Downstream • 70% over 6Mb/s • 100% over 2Mb/s • Upstream • 95 % over 800kb/s • 100% over 400kb/s

  13. Throughput/performance using N3 Speed Tester

  14. Average Down Speed at Trial Sites Averagedownspeed at trial sites

  15. Average Up Speed at Trial Sites

  16. Conclusions • IPstream offers significant benefits • Small possibility that some locations may not benefit • Issues during trial mostly linked to new PSTN or local configuration • Upgrade main & branches for maximum benefit • Change DNS and web proxy settings for branches into N3 directly • Outstanding questions over mass migration will be validated in phases 2a and 2b • Trial findings have been reviewed with and accepted by the GPITC of the BMA

  17. Funding • NHS sites migration funded • Locally funded DSL ‘top-ups’ not required • Locally funded PC upgrades may not be required • Local decision to evaluate

  18. February 08 May 08 June 08 November 07 Timeline • 1st trial • (Phase 1) • November 2007 • 45 small sites • Feedback on product performance • 2nd trial (Phase 2a) • February 2008 • 38 small sites • Test migration process • Pilot • (Phase 2b) • May 2008 • 200 sites • Test mass migration process • Mass migration • (Phase 3) • June 2008 • 12 months • CAL by CAL

  19. New broadband product: IPstream Dean Smith N3SP Network Architect

  20. IPstream • Rate Adaptive broadband service • Similar to home broadband but N3 utilises the Max Premium or Business variant • Offers increased upstream bandwidth over residential offering. Up to 832 kb/s

  21. IPstream - Benefits IPstream is a fast broadband service that has been proven to bring the NHS: • Consistent 2 Mb/s download and 600 kb/s upload for Faster local applications performance • Higher Main and Branch speed • Ability to make the transmission of scanned documents more efficient • Faster downloads for software downloads/patches • Improved Internet browsing speed

  22. IPStream Speed Upstream and Downstream speeds affected by 2 factors • Line Rate negotiated by the DSL Equipment • Standards based • As the line gets noisier…bandwidth is reduced • Distance and Line Quality affect noise • Throughput achieved End-to-End • Max Premium is given preferential treatment to Max within BT Wholesale • Residential throughput affected by congestion within the Service Provider Network. • N3SP and NHSCFH have control of this factor

  23. Maximum Stable Rate (MSR) • 10 day ‘settling’ period • Router and Exchange equipment synchronise • Variance in speed during this time • Maximum Stable Rate determined by BT Dynamic Line Management • Not an upper limit but a benchmark used within BT Wholesale

  24. IPstream: VPNs and VoIP • N3 VPNs • May need a router upgrade if Cisco1701 • Higher throughput requires more CPU for encryption • Prior to migration, VPN will be enabled over backup circuits • Voice over IP • Currently not supported for business critical voice services • N3SP continuing to look at solutions

  25. Quality of Service • QoS • N3 Model Implemented on all services • End to End marking will be maintained • Not recognised across IPstream N3 QoS Marking & Policing Preferred to Residential Full N3 QoS Model Application Flow N3 Core Network IPstream LAN N3 Central Aggregation Routers N3 Customer Router

  26. Core infrastructure • Two DSL aggregation PoPs • Each with 622Mb/s central • Direct DWDM connections to Internet Gateway • Allows other broadband offerings and other suppliers to be connected in the future

  27. N3 Core N3 PoP N3 PoP Faraday N3 PoP Colindale N3 PoP N3 Internet Gateway DSL Aggregation Infrastructure DSL Aggregation Infrastructure IPstream Other BroadBand Core Infrastructure DWDM Ring

  28. Mass migration: Technical • CAL by CAL migration • No impact to firewall configuration • 3 Stages • N3SP remote router preparation • No interruption to service • Supplier migration to IPstream • Max one hour downtime, backup service maintained • N3SP remote configuration update • New SIN allocated • No interruption to service (except VPN)

  29. Main and Branch connections • Main and Branch migrated independently • N3SP re-build VPN configurations after migration • May incur downtime • Optimisation of systems to minimise disruption

Today’s migration - a stepping stone for future technology development Allows customers access to new technology developments Allows NHSCFH to access best commercial terms & best value for NHS Catalogue services provided on 3 years terms

  35. Scope - Connections Being Migrated • All Datastream connections • For identified catalogue services • Mass migration • Exclusions • Community of Interest Networks (CoINs) • Kingston-Upon-Hull

  38. Migration numbers

  39. Datastream Catalogue Services • No new Datastream orders will be delivered • Immediate DSL requirements will be delivered with IPstream

  40. Other services • Non DSL services not in scope for mass migration

  41. Mass Migration strategy • Datastream connections • CAL by CAL • No impact to firewalls • Remote process • Re-use equipment (in most cases) • Seamless • Limited downtime

  42. Special Considerations • Bespoke • Load Balanced • Out of Limits

  43. Mass Migration Implementation Migration Manager places IPstream order in N3 CRM • N3SP remote router preparation • No interruption to service • Supplier migration to IPstream • Max one hour downtime, backup service maintained • N3SP remote configuration updated • New SIN allocated • No interruption to service (except VPN) N3SP email the Migration Manager to confirm the order has been received N3SP begin processing the order CAL by CAL N3SP email the Migration Manager to advise of the date of migration The migration to IPstream takes place – 3 stages

  44. Mass Migration Implementation Migration Manager places IPstream order in N3 CRM N3SP email the Migration Manager to confirm the order has been received N3SP begin processing the order CAL by CAL N3SP email the Migration Manager to advise of the date of migration The migration to IPstream takes place – 3 stages N3SP will email the Migration Manager to confirm the migration has been completed – returned SRC required

  45. VPN migration strategy • Migrated independently • Remote reconfiguration work required

  46. PC + DSL Strategy • PC + DSL • Part of mass migration
