• Interxion, Parkwest – live Feb 2009

• Fit out nearing completion

• 102m2 geographically diverse from existing Servecentric & Citywest PoPs• Client colocation & hosting• Off-site backup & replication• Future services

• INEX presence

Refreshed PoP Strategy


Refreshed PoP Strategy• Extend reach, resilience, capacity

• New PoP in LYIT• migration from e|net PoP

• Upgrade client sites toPoP status (with resilience project):• Cork IT• Limerick IT• Athlone IT• ... and more ...


Schools – Phase II• 99.999% HEAnet backbone availability since

inception in 2005(Source: Norcontel Schools Broadband Program Evaluation Report 2009)

• Single day high of 3,745 (of 4,000) schools connecting the the internet

• 2,850 schools connecting daily (monthly avg.)• Traffic profile doubling approx. every 12-18 months

• Phase II rollout commencing Q4 2009:• Increased bandwidth (2Mb ~ 7Mb typically)• Reduction from 1,850 satellite connections to 127.


Schools – Phase II

Schools traffic profile: 2007 to 2009 (2 years)


Schools 100Mb• Renewed Program for Government to deliver

100Mbit/s connectivity to all post primary schools• Pilot of 78 schools by 1st April 2009• All approx. 735 schools by 2012

• Sponsored by DCENR, who requested HEAnet to manage the program

• Leverages public investment in HEAnet core net

• Acknowledge client community support re interconnecting schools at regional PoP locations


Out-of-Hours NOC• Now a full production service

• NOC available for P1 (complete site) outages, 24 x 7 x 365

• Increasing number of tickets• increased complexity of

network• significant planned

works through 2008-9• better issue tracking

HEAnet Evolution & Revolution• The HEAnet network continues to evolve:

• 2008/9 – Major Network Evolution• 2009/10 – Network Resilience project

• Software Development• 2009 – Building custom software to better manage

and monitor customer services


Lambda Extension• Expand the use of the CWDM spectrum

• from 8 to 16 wavelengths (without power)• passive equipment from ‘Cube Optics’ (Germany)

• Retrofit multiple DWDM channels within a single CWDM channel• facilitates co-existence of 1G & 10G wavelengths on

the same fibre.


Lambda Extension

1470nm 1490nm 1510nm 1530nm 1550nm 1570nm 1590nm 1610nm

Up to 16DWDM channels insertion

into one 1550nm CWDM filter

1547.72nm 1553.33nm1549.32nm 1550.92nm 1552.52nm1548.51nm 1550.12nm 1551.72nm

0.8nm spacing

20nm spacing


Lambda Extension• Existing fibre ring between HEAnet office and

TCD being used as test bed

• All required equipment installed, configured and operational

• Next step: formal testing of 1G and 10G channels on new DWDM and existing CWDM channels.


Video Streaming• Simple multimedia hosting

• Accessed by federated login• uses Edugate

• Content can be embedded in any webpage• or used as a podcast,• or a Windows Media file, etc.

• Content automatically ‘transcoded’ into multiple different formats


• Each version of the content has its own ‘embed’ code

• Selection of thumbnails to choose from

• ‘Transcoding’ work is queued for processing – user does not have to wait


Video Streaming• System developed in-house

• Summer ‘09

• Currently on trial with University of Limerick

• Ready for more people to trial

• Aim to end trial & enter production, Q1 2010


eduroam• Roaming wifi access for users

• Use existing ‘home’ credentials when visiting a guest network

• Users can get internet access worldwide in any of the eduroam enabled institutions


eduroam• Now available in 13 Irish sites and 1000’s of

European sites

• Guides / wizards / profiles available for:• Windows• Mac OS X• iPhone / iPod• Nokia

• We will help you with any other platforms you might need


Mirror Service• ftp.heanet.ie

• well known service• providing fast access to many projects

• Challenges• scale traffic to 10Gbit/s• provide resilient scalability


Mirror Service – why?• Given growth of access capacities?

• 1Gbit/s not uncommon, 10Gbit/s not too far away• content providers often have 1Gbits/s or more too

• Simple scaleability• very popular content will always beat a 1Gbit/s pipe• resilience• sharing cost


Mirror Service – what?• Application transparently use global mirrors

• firefox updates• ie.releases.ubuntu.com, ftp.ie.debian.org• ClamAV anti-virus updates• SourceForge• many more...

2010 and beyond...• Faster networking

• 40G v 100G standards?• 10G connectivity to clients?

• Different connectivity• layer 2 point-to-point connectivity (rather than L3?)• layer 1 optical lamdbas with GMPLS?

• Ubiquitous networking• 3G / HSPA connectivity• Wimax
