Current State of LHCONE

You can see as of the current date, and is clearly a work in progress.

Thanks to Mian Usman (Dante) for the picture as part of the architecture group discussions.

Summary of the LHCONE Architecture Meeting 08/07/11

Notes from Artur

Participants: Jim Williams, Gerben van Malenstein, Bill Johnston, David Foster, Alberto Escolano, Gerard Bernabeu, Richard Hughes-Jones, Roberto Sabatino, Mian Usman, Thomas Tam, Artur Barczyk

"what's there":

DANTE/GEANT (Roberto): GEANT setup with 6 nodes is ready. RENATER has been connected, GARR will be connected on July 14, followed by REDIris end of July. 2 route servers operational. GEANT is distributing addresses from their own address space, not any more from the subnet assigned by Edoardo.

LHCONE Prototype News as of Today

At the architecture phone conference, the Dante/Geant prototype is moving along with Renater connected and DFN and GARR due to be connected on the 14th. Rediris should be connected in August. The Open Lightpath Exchange prototype is also progressing with ongoing work with Netherlight, CERNLight, NorthernLight and CzechLight to investigate connecting the NDGF and NL-T1 as well as associated T2's.

100G Link between Netherlight and CERNLight

The dark fiber connecting Amsterdam and Geneva has been tested and shown to be error free validating the use of the fiber for 100G traffic.

LHCONE Should Focus on L2 services

Even though L2 redundancy and sharing across multiple circuits was an unresolved problem in Washington leading to the conclusion that a practical first step was to connect L2 "islands" with a more traditional L3 approach, the recent article in telegeography seems to indicate that we are on ther right track concentrating on L2 services: “Ethernet VPN services are generally more cost effective than MPLS IP VPN services for capacity requirements above 50 Mbps, and are most appropriate for linking high-capacity headquarter sites and data centers. MPLS IP VPN services tend to be better suited for linking large numbers of sites with more modest capacity requirements,”
