Networks critical to the shared services agenda
Network for the Community
Education, Digital inclusion, Healthcare, Economic development,
environment
Cost reduction
Shared platformFor processes, data and applications

Who stands to benefit?• County, District and Borough Councils• Schools and Further Education• Healthcare• Police and emergency services• Local communities• Third sector (charity workers)• New and transforming businesses

Education• Enables effective use of Learning Platforms
– Content and usage doubling every 18months – More personalised Learning– Students moving from consumers to collaborators
• Equal access for disadvantaged students• Enables multiple use of facilities e.g. for adult
education• Meeting BSF guidelines
On Broadband in schools:“… We've got evidence that shows that it is probably worth half a grade at GCSE difference, if you have access to (on-line) resources…”
Neil McLean, Executive director of Becta

Environment
• Network consolidation reduces carbon impact
• Enables flexible working to reduce council employees’ business travel and commuting
www.mlltelecom.com
Digital Inclusion
• Platform for broadband in disadvantaged areas– Often those people who use most council services
• Platform to target broadband ‘notspots’– Local business stimulus – Develops rural IT-dependant businesses– Attracts and retains businesses, jobs and skills
“We need to ensure that EVERYONE has access to high speed Internet if we're all to compete on a "level playing field".
Federation of Small Businesses

Care Closer to Home
• Connect local people to deliver collaborative solutions– Social workers, health workers, security workers
• Platform for delivering care in the home

Security and assurance concerns• Today restricted data usually sent over private
network• Shared networks can provide connectivity to GCSX
(Government Secure eXtranet) for sensitive data• Shared networks can prioritise traffic types
• However;• Any shared network solution MUST assure complete
privacy of restricted data from other community groups
• In state of emergency certain user groups MUST be given assured use of limited network capacity

How to build a shared community network
• Low Cost• Flexible • Trust
– Availability– Privacy – Security– Bandwidth assurance
www.mlltelecom.com
Each shared service needs its own connectivity
But what’s inside the cloud?

Delivering Security

MPLS provides complete traffic separation between community user groups
Common Criteria Certified premise equipment encrypts restricted data for added security
GCSX
Map encrypted tunnels directly into MPLS to assure QoS
Secure Interconnect to GCSX
www.mlltelecom.com
Delivering Assurance• MPLS Traffic engineering can ‘reserve’ minimum bandwidth for a
class of user• All the bandwidth is available when there is no congestion• Profile can be changed under network fault conditions if desired• Multiple levels of QoS (Quality of Service) available per user – eg for
voice, video, client-server, browsing…
MPLS LSP 1
MPLS LSP 2
Encrypted

Delivering Customised Benefits• Customised traffic prioritisation policy
– By application– By site– By user or groups of users
• Flexible Bandwidth• Option to integrate WiMAX and xDSL access• Multicast for video broadcast
– Staff briefings– News– Training and lessons– We recommend use of Next Gen Multicast VPN (NG-MVPN) proptocol within the core ) as it provides better integration with
MPLS than PIM (Protocol Independent Multicast)
• Direct Connections to other Govmnt Networks – JANET, GSCX…• Option to host content, applications, firewalls in core
www.mlltelecom.com
Delivering Availability
• House equipment in a secure exchange environment where possible– Redundant access circuit risk – Allows access for planned works out-of-
hours
• MPLS core– fast re-route– Simplified routing topology = more stable
network
• Use 24x7 proactive management
www.mlltelecom.com
Example – East Sussex County Council’s NGN
• 1Gbit resilient fibre core• 150 Schools connected by radio at 10-
100MBit/s• Other schools connected on fibre• Council offices ready to benefit from cost
advantage of existing community network
www.mlltelecom.com
Example - North West County Council • 9 site 1GBit/s resilient core• 180 Access sites connected at 100MBit/s
• 5 Year Pricing• BT Ethernet Circuits* - £6.111M• MLL Switched Core Network* - £5.021M• Saving of 18%
• And it’s more resilient, more flexible and lowers CPE costs
* Based on standard MLL Telecom pricing of BT circuits* Both designs subject to similar BT excess construction charges
www.mlltelecom.com
Example – East of England County Council
• 500 Schools connected at 10 - 40MBit/s• 150 Council offices connected at 100Mbit/s
• 5 Year Pricing• Initial Project Pricing £20M*• MLL Private Switched Network £15M*• Saving of 25%
* Both designs subject to similar BT excess construction charges
