nbe the project
NBE – the project
  • Project plan and management
  • Inventory of sites
  • Criteria, priorities
  • Surveys and schedules
  • Procurement, multivendor scenario

7

project goals
Project goals
  • A network for connecting clients, with the following features
      • High bandwidth
      • Multi-service
      • Resilient
      • Scaleable
      • Flexible
      • Secure

9

goals multi service
Goals – Multi-service
  • Service orientated connectivity, e.g:
    • Private secure connection per Institute to An Chéim
    • Interconnectivity with the Government VPN
  • Not just focused on internet reachability
  • Capable of delivering access to multiple services using the same infrastructure
  • Advanced networking protocols supported – IPv6, multicast

10

goals resilience
Goals - Resilience
  • Seek to build in circuit, equipment, path, and routing diversity
  • Equivalent service levels on primary and secondary
  • Using multiple ducts, termination points, equipment
  • Using a robust routing technology (BGP)
  • Can make use of existing connectivity via other service providers

11

goals scalability
Goals - Scalability
  • Can deliver multiple 1 Gigabit/s circuits
  • Can operate at line speed end to end
  • Capable of offering even higher speeds subject to requirements (10 Gbps, higher)
  • 10 Gbit/s access for clients being explored
  • Technology refresh available for 40 Gbit/s…
  • …and similar for 100 Gbps in development

12

goals flexibility
Goals - Flexibility
  • Not subject to telco business case scenarios
  • Not tied by contract to any particular network implementation technology or model
  • Can use a mix of fibre and traditional managed Ethernet circuits
  • Fully compatible with existing networks (no big bang changes)
  • Capable of delivering wavelengths to clients if the need is proven

13

client perspective
Client perspective
  • Client priorities are key throughout
  • Aim is to keep change to client sites minimal
  • HEAnet installs managed routers and switches in addition to current network equipment
  • When ready, services can be tested and migrated individually
  • No Big Bang change
  • No change without explicit client agreement

14

typical installation
Typical installation
  • Research of available providers (fibre, managed circuits), usually via Tender process
  • Client site survey by provider with client
    • Paths identified, leading to “way leave” contracts
  • Civil works commence
  • Fibres are pulled into building, and subsequently spliced
  • Routers and switches are delivered, configured by HEAnet
  • Services can be tested and used by client

15

new link services
New link services
  • Point-to-point Ethernet links (p2p)
    • 1 Gbit/s, Ethernet framed
    • Ethernet Port Service
    • Ethernet VLAN Service
    • No aggregation
    • Automatic monitoring/graphing

16

some examples
Some examples
  • Services- connectivity- institutional access and security- p2p
  • Applications- Oireachtas- ICHEC- An Chéim- UCLP
  • Client examples- DCU

lan extensions ryan academy
LAN Extensions – Ryan Academy
  • Centralise services, both voice and data
  • Servers centrally located at DCU
  • IP Telephony Extension to Nortel Meridian
  • Seamless telephony integration
  • Security cameras and DVR remote view and monitoring
  • Buildings Management System
  • High-End Video Conferencing > 2 Meg/sec
  • Reliability
  • No onsite technical support ( low maintenance )

19

lan extensions mater dei institute
LAN Extensions – Mater Dei Institute
  • Sister College of DCU
  • All Servers consolidated in DCU
  • Previous difficulties with server location in MD ( Dust and no Aircon )
  • Minimal on-site technical support ( mainly helpdesk 2/3 days per week )
  • No requirement for Sysadmin
  • Reliability of service

20

under the bonnet
Under the bonnet
  • DWDM, CWDM
  • Ethernet switches
  • MPLS
  • New routing strategies
  • Out of band access for network management
  • CPE, routers
  • Outsourcing of L2 ops management
  • Provisioning tool
  • Contributions, SLA

21

multiple sources
Multiple sources
  • We make use of many fibre providers to connect at the lowest cost for our requirements
    • E-net
    • Dublin City Council
    • ESBT
    • BT Ireland
    • NTL
    • Aurora

22

transmission technologies
Transmission technologies
  • We use a heterogeneous mix of technologies to achieve our goals:
    • CWDM in metropolitan areas gives us multiplexed fibre services for short hops
    • DWDM between regions to give the same for longer hops
    • MPLS network to give multi-service offering
    • Multiple physical connections to add resiliency

25

how does it do it
How does it do it?
  • Circuits are managed using an automated provisioning system
  • Based on client requirements, the system is used to configure routers, service monitoring portal
  • Aim to have client use the tool directly, with administrator later checking/approving circuit change requests

27

the bigger picture
The bigger picture
  • NIBEST – NW link with NIRAN
  • UKERNA DF – SuperJANET 5 links
  • GÉANT – hybrid networking
  • Transit – preparing for the next step
  • INEX – peerings and more

project history
Project history
  • In 2004, we commenced implementation of dark fibre point to point links
  • Followed by additional of CWDM and DWDM equipment to increase service possibilities
  • Commenced work on an automated provisioning tool to create and manage configurations
  • Quickly grew into a heterogeneous network combining a mix of technologies and providers
