Objectives

Connect. Communicate. Collaborate • To provide and promote project-wide meetings… • To provide a forum for discussion and resolution of networking and technical issues… • To discuss, critically review and develop results and ideas from SA1, SA2, JRA1 • Provide input to EXPReS outreach team

Status of Global Connectivity

Connect. Communicate. Collaborate • • Europe Dedicated 1Gbps circuits in place from: – Westerbork – Jodrell Bank – Cambridge – Medicina – Torun Expected soon: – Yebes (Madrid) – Effelsberg??

– Ventspils??

– Onsala??

• China Shanghai achieved 512Mbps in UDP tests to JIVE: fringes at 256 Mbps • Australia Achieved 512Mbps to JIVE as part of the APAN demo • Chile Tigo hoping for 128Mbps to Europe by May 2008

Connectivity (continued)

Connect. Communicate. Collaborate USA • Aricibo (64Mbps achieved) –future plans?

Japan • Mizusawa VERA has achieved 300Mbps to EU –more?

FABRIC • 4Gbps from London to Stockholm – Hoping for Jodrell-Onsala soon

Update: APAN Demo

Connect. Communicate. Collaborate • APAN Meeting in Xi’an, China – Demo connecting Shanghai to JIVE – Utilising the new ORIENT circuit – Highly successful -256Mbps fringes achieved – Press release well received
