N3 Broadband Migration Customer Workshop Neil Jackson N3SP Programme Manager
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
N3 Broadband Migration – Context Len Chard NHS CFH
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)
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
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
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
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
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
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
Average Down Speed at Trial Sites Averagedownspeed at trial sites
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
Funding • NHS sites migration funded • Locally funded DSL ‘top-ups’ not required • Locally funded PC upgrades may not be required • Local decision to evaluate
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
New broadband product: IPstream Dean Smith N3SP Network Architect
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
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
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
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
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
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
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

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)
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
