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
