1. PSBA Developments Gregynog Colloquium 2010

3. PSBA Overview Public Sector Broadband Aggregation Assembly-led collaborative national communications service Enable greater efficiency and improve collaborative potential Assist in the delivery of improved services Initial stakeholders: HE/FE, Health sector, Unitary Authorities

4. The PSBA Network Procurement completed July 2007 Award of 7-year �74m contract to Logicalis on Aug 31st 2007 Single unified national broadband network Initial order to connect 1000 end-points including: 50+ HE/FE/Research sites 22 Unitary Authorities 650+ GP Practices Acute health sites & services

5. PSBA Network Topology Resilient Ring Design BT Wavestream core 2.5Gbps scalable to 32Gbps 12 Core Points of Presence 22 Core Neighbourhood Access Points (NAP�s) 172 Local NAP�s (Local Loop Unbundled Exchanges)

6. PSBA External Connectivity SuperJANET5 & Internet Dual resilient 10Gbps feeds to SJ5/Internet (active/standby) GCSX Dual resilient connections (active/standby) Health Gateway Dual resilient 100Mbps direct from PSBA in to HSW and onto N3 (load balanced) VRF Gateway Services/ IWF Filtering Dual resilient VRF Gateways at 2Gbps providing IWF filtering (active/standby) ADSL Dual resilient 100Mbps connections in to Griffin network (load balanced)

9. PSBA Resilience Ring design can accommodate one break on core backbone Dual feeds to JANET Resilience to NAPs based at Unitary Authority premises using microwave overlay Multi-sector Network Neighbourhood Design groups building �collector arcs� running off core-backbone No HE/FE sites have yet setup resilient connections, although option exists

10. Utilisation of Network 2.5Gbps DWDM (Wavestream) backbone Capacity management process continually being refined Simple upgrade path � add additional 2.5Gbps wavelength (scale up to 32Gbps) Southern sections of network showing highest utilisation Swansea � Cardiff section primary candidate for upgrade Upgrade of NAP-Core links to 1Gbps complete by Q3 2010 Multi-sector Network Neighbourhood Design groups building �collector arcs� running off core-backbone can reduce loading on backbone

11. PSBA Connectivity Services

12. PSBA Connectivity Services ADSL ADSL �max� up to 8Mbps 2.5:1 or 5:1 contention ratio Griffin Internet as partner (dedicated interconnects to PSBA) SDSL Bonding copper pairs to provide symetrical service to BT Exchange Offers bandwidths up to 24Mbps (but usually not cost effective after 10Mbps) Updata as LLU partner

13. PSBA Connectivity Services Ethernet (LES, WES type services) Megastream products LES, WES 10, 100, 1Gbps Special Purpose (Dedicated) Bandwidth Lightpath services (speak to JANET first!) Also available upon request Telco resilience, diverse routing, separacy

14. PSBA Connectivity Services Need to remember that PSBA is a shared resource Not suitable for instances where dedicated �nailed-up� bandwidth is required For those who have concerns about congestion Contention ratio of 5:1 on shared infrastructure Utilisation of shared infrastructure monitored 60% utilisation triggers alerts for further analysis Regular utilisation of 80% normally triggers upgrade

15. PSBA NETWORK SERVICES

16. Quality of Service Diffserv protocol for specifying and controlling network traffic by class so that certain types of traffic get precedence over others. 6 levels or categories of service DSCP values maintained during transit across PSBA Traffic shaping applied outbound from PE to CPE 5 standard QoS Templates to chose from Bespoke option available No additional charge

17. QoS Templates Option 2: Voice & Data

18. Multicast JANET mandatory requirement Originally a problem hence HE/FE placed in the Global Services or BGP layer Resolved May 2008 Internet Multicast Support Support for Multicast VPN�s Inter-VRF multicast Support Still few applications demanding multicast Traffic-Wales, Access-Grid, any others?

19. IPv6 JANET mandated requirement Network not dual-stack (yet...) IPv6 Peering with Janet IPv6 supported through 6PE technique Isolated islands of IPv6 in Wales No requests from end-sites to carry IPv6 over backbone... yet

20. PSBA NETWORK TRANSPORT

21. MPLS and VRFs Multi-Protocol Label Switching Standards-approved technology for speeding up network traffic flow MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet Saves time needed for a router to consult routing tables for the address of the next node to forward the packet to MPLS allows most packets to be forwarded at the layer 2 (switching) level rather than at the layer 3 (routing) level. MPLS carried out at the Provider Edge node on PSBA, not on the Customer Premise Equipment.

22. MPLS and VRFs Virtual Routing and Forwarding Technology that allows multiple instances of a routing table to exist in a router and work simultaneously Increases functionality by allowing network paths to be segmented without replicating network infrastructure Segmentation increases security and can eliminate need for encryption Organisational VRFs (or even sector-wide VRFs) can be created VRFs prevent traffic from being forwarded outside a specific path, and keep out traffic that should not be part of VRF VRFs are approved by the CESG

24. Routing Between CPE and the PE Each site should have Customer Premise Equipment (CPE) device Demarcation point for the Managed Service CPE does not need to be MPLS aware - runs standard IP software Each VRF is presented on a separate dedicated physical interface on the CPE device �. So this is an issue for those 7 HE sites that don�t have a CPE device! Should be resolved within next six months

25. OrganisationalVRFs

26. Multiple Occupancy Site Service (MOSS) Good example of collaboration and aggregation Not aware of any examples in HE/FE sector yet Opportunity for two different organisations that share a site to have a single connectivity service onto PSBA Traffic to each site can be separated using VRFs Single CPE for the site with each organisation receiving a physical interface to connect to their LAN

27. PSBA TODAY

28. Demand for PSBA Connectivity Initial order was for just over 1000 sites 2035 sites currently �on-net� Orders already placed for 3000+ sites by end Q3 2010 Very strong uptake from Unitary Authorities 5 Already signed: Denbighshire, Gwynedd, Blaenau Gwent, Neath-Port Talbot, RCT 13 In discussion: Caerphilly, Torfaen, Monmouthshire, Newport, Merthyr (Gwent NND) Carmarthen, Ceredigion, Powys, Pembrokeshire (Mid & West Wales NND) Swansea, Cardiff, Bridgend & Vale of Glamorgan (South Wales)

29. Demand for PSBA Connectivity Services Blue-Light Services: North Wales Fire & Rescue, Mid & West Wales Police forces: Dyfed Powys Police, Gwent Police, South Wales Police Assembly Sponsored Public Bodies: National Museums & Galleries, Countryside Council for Wales, Welsh Audit Office, National Parks Goal Architecture To provide connectivity services to every single Public Sector Body across Wales Probably unachievable with PSBA v1.0, but worth aiming for! Momentum increasing

30. Demand for PSBA Connectivity Services From FE sector significant interest ColegPowys already migrated WAN onto PSBA summer 2009 Solution Design Packages delivered to: ColegMorgannwg, Coleg Gwent, Barry Colllege Discussions and quotes being prepared for: ColegMenai, Deeside/Llysfasi, Ystrad-Mynach College, Neath-Port Talbot College, Bridgend College

31. Demand for PSBA Connectivity Services HE sector � not such strong uptake� yet? Some institutions single campus or have WAN links <5km of main site Some Universities have extensive private-fibre installations Some interest from Universities where researchers may be working in Health premises Only 3 of 11 have had serious discussions with PSBA Will this change? Difficult to tell�.

32. PSBA & Multi-sector COLLABORATION

33. Neighbourhood Network Design Activity Multi-sector membership Collaborative approach to gain best design Contribution of funds that would be spent on institutional WAN into �shared� fund. Permits better reach of PSBA, increases footprint of network Moves responsibility for managing/operating institutional WAN onto PSBA Opportunities for improved resilience, security, follow on PSBA services Should not compare �Managed Service� to �Wires in the Ground�

34. PSBA FUTURE SERVICES

35. Laying the foundations for future services

36. PSBA Hosted Voice Services PSBA is capable of carrying Voice traffic for all users QoS markup is on all CPE routers just needs to be enabled as needed. Health already have Welsh Health Telephone Network (WHTN) running over PSBA Health have long history and experience of using QoS to route voice traffic �on-net� for toll-free calls. WAG have provided seed-money from �Invest to Save� fund following viability study Multi-sector PSBA Voice Services core team setup Meet with suppliers, see what market can deliver Look at future technology and services Decide what should be procured

37. PSBA Voice Services Main remit Use PSBA network to provide connectivity to enterprise telephony solutions for toll-free �on-net� calling between organisations and access to aggregated low-cost tariffs Provide hosted telephony services to facilitate low cost deployment and operation of telephony as an alternative to organisations buying/managing their own enterprise solutions Supplier workshops held January 2010 Procurement now underway

38. PSBA Voice Services Quick win would be a Welsh gateway for fixed-mobile calls to reduce mobile call charges Should look at solutions that offer a roadmap towards unified communications capabilities Number plan, directories and IP addressing are fundamental and need to be addressed at an early stage Multi-tenanting capability will be mandatory to facilitate provisioning / management / administration on a per customer basis Solution must deliver tariffs as good (ideally better) than those available via Value Wales.

39. PSBA Videoconferencing Service Already have two VC services that complement one another WVN and Health VC Service (WHVN) Aggregation of both WVN and Health VC service to form new PSBA Service Preserve knowledge and experience of both WVN and Health VC service. Initial work to channel funds through PSBA to maintain existing VC services Work to aggregate WVN and Health VC services within 18-24 months Will continue to use JVCS � booking system is essential.

40. PSBA Colocation/Datacentrefacility Joint venture with Torfaen CBC Initially can accommodate 60 racks Resilient connectivity to PSBA Network 7.3Kw per rack, n+1 resilient power, n+1 resilience for cooling Security Internal secure shell CCTV and 24hr staffed facility Electronic access control to room and to racks Hot air containment (full segregation and brush strips and blanking panels) Settings: inlet temperature 24�

42. THE PSBA PROPOSITION

43. PSBA underpinning WAG Strategy PSBA not just a technical solution to deliver greater efficiency, it will provide much wider strategic benefits for public services as a whole. PSBA will provide the building blocks for a whole host of other innovations, such as combined data storage and better value telephone services. � PSBA not an exercise in control and command. The objective behind an �adopt or justify� approach is to catalyse an informed, contextualised response at the right level, which can be publicly accounted for. PSBA is not about forcing a particular decision to the detriment of an organisation.

44. The PSBA �Proposition� Being part of the PSBA community brings additional benefits: Whole range of central services working on your behalf Service management Commercial negotiations Security accreditation PSBA is about more than buying network connectivity, it involves supporting a longer term vision of information sharing and collaborative working.
