Mirror Service• ftp.heanet.ie
• well known service• providing fast access to many projects
• Challenges• scale traffic to 10Gbit/s• provide resilient scalability
HEAnet Conference, 2009
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
HEAnet Conference, 2009
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...
