INTERNATIONAL NETWORK UPDATE

RECAP: WHAT MAKES UP AN INTERNATIONAL NETWORK?

  • Physical links to other countries eg Subsea Cable Systems.
  • Peering with other Network Operators which provide direct access

to them and their customers.

  • Dedicated links with large content providers eg Google.
  • R&E Peering – Provides direct access to the various other

Research Networks around the globe.

  • IP Transit – Provides a way to reach all internet connected

destinations that we can’t get to via one of the above.

HAWAIKI

WHAT DID WE HAVE?

  • Until recently REANNZ had

20Gbps of capacity on the Hawaiki Cable System to both Australia and the US.

  • Physical PoP locations in

Sydney, Oregon and Seattle.

  • Vodafone IP Transit Service

used to fill in the gaps that we couldn’t pick up elsewhere.

KEY DESIGN PRINCIPLES

  • Scale Bandwidth to meet the current and future needs of our

Membership.

  • Ensure our International Network is fault tolerant.
  • Expand the reach of our Research and Education Connectivity.
  • Gain greater control over traffic flows with less reliance on 3rd

party networks.

  • Evaluate the IP Transit Service to ensure it is still fit for purpose.

INTERNATIONAL NETWORK UPDATE

KEY UPDATES/CHANGES

  • REANNZ now have 50Gbps of capacity to both Australia and the

US bringing forward our scheduled upgrades with Hawaiki.

  • A second Sydney PoP has been commissioned which uses a

different Cable System to provide 50Gbps of resilient connectivity back to NZ.

  • CenturyLink(Formerly Level 3) have replaced Vodafone as our IP

Transit Provider and now connect to us in Sydney and Seattle.

  • Planning is underway to commission new PoPs in Hawaii and

Gaum – This will provide better R&E connectivity and lower latency paths into Asia. Completion due later this year.

IP TRANSIT

  • As of last week CenturyLink now provide our IP Transit Service in

place of Vodafone meaning that any traffic we can’t deliver via one

  • f our other connectivity options (Eg Peering Exchange or NREN)

will route via them instead.

  • Connect to REANNZ in both Sydney and Seattle.
  • Are a Tier 1 Service Provider meaning that they sit at the top of the

hierarchical Internet Backbone and have an extensive global presence.

  • Initial testing into Asia showed latency improvements.
