Network Infrastructure

12th October 2005, 4th EVN-NREN Meeting, Schiphol Airport, Amsterdam

Michael EnricoNetwork Engineering & Planning, DANTE


• Reminder of Remit

• Procurement history (why so long?)

• Planned GÉANT2 build

• Equipment to do it

• Service overview

Agenda


• Upgrade GÉANT (1)– Reached end of 4-year funding cycle– Possibility for greater infrastructure ownership (fibre)

• But requires longer term views than hitherto adopted

• Provide support for new services– Not just a bigger IP network…– …support for high-capacity P2P services…– …and (if needed)…lots of them!

• Facilitate (joint) R&D efforts• Extend geographical coverage

GÉANT2 (GN2 I3) Remit

Services


• Continue to support usual IP services– BE, LBE, PIP, mcast (v4), v6, mcast (v6)

• Enhance these with:– implementation of new features as required and available

• e.g. embedded RP for IPv6mcast– improved performance monitoring (JRA1 & SA3)– more automated PIP provisioning (SA3)– network security best practice (JRA2)

• Continue to support emulated L2 P2P services– L2VPNs for lower capacity [“lightpath”] support

• Add portfolio of new L1 and L2 P2P services– cost-effective support for high-capacity [“lightpath”] services

• up to 10G (for now)– emphasis placed on support for Ethernet framing– experiment with translational P2P service support

• e.g. native gigE to GFP VC-4-7v over SDH– experiment with support for various protection modes
