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 (NAPs)
172 Local NAPs (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 VPNs
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 dont 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

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
41. PSBA Colocation/Datacentre facility
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.
