Trans Eurasia Information Network 1st link: Korea- France 2001 (2 Mbps)

From TEIN1 to TEIN2Intra-Asia regional networkAsia-Europe inter-regional links10million Euros European Commission funding + funding by Asian partner countriesTEIN2 programme aims to:build and operate a regional networkpromote network usage through catalysing applicationstrain technical staff in developing countriesreduce the digital divide

TEIN2 is part of the regional (APAN) network fabricLaunched at Halong Bay in June 2006Provides short paths to Europe (going west)Provides short paths WITHIN the APAN region (instead of transit via US or Japan)Capacity ranges from 45Mbps to 2.5GbpsComplements the multi-Gigabit networks from Japan and Korea to the USCatalysed new NRENS in Malaysia, Indonesia and Vietnam

TEIN2 network started Jan 2006, now connects:

30million researchers and students 4000 institutions 10 countries

PoPs in Singapore, HK and Beijing; NOC in HK

Timezones and PopulationsTEIN2:Member countries represent 1/3 of the worlds population in a timezone range spanning only 3 hoursTEIN3Potential member countries represent almost 60% of the worlds population in a timezone range spanning only 5 hours

Small timezone range is critical for interactive collaboration

TEIN3 Network TopologyTo be determined from the tender results (not pre-defined)Current TEIN2 hub locations to be reviewedEurope-Asia links going West from Asia, likely to be 622Mbps, 2.5 or 10 GbpsIntra-Asia links likely to be in range 155Mbps to 10Gbps depending on partner needs, affordability by project and partner, and topology requirements (cost for some countries still currently very high)

Thank you

This page shows the demonstration of Mobile Classroom conducted at Burirum, the north-eastern part ofThailand. Lecture was given directly from the archaeological site at which an ancient furnace was discovered. Furnace was used to produce ceramical and iron products around 1,000 years ago. Lecture was sent from the archaeological site over the satellite directly to SOAS, UK. Satellite dish, connection and full satellite networksetup was kindly donated by the Telephone Authority of Thailand for educational purposes.Mobile Classroom (MC) is a real-time e-learning application used in VClass platform.It uses Session Initiation Protocol (SIP) as its main underlying protocol. MC is integrated into an existing VClass e-learning platform and uses its Learning Management System (LMS) in order to operate with full potential. Mobile Classroom can be used to setup various learning environments ranging from a static remote lecture to a completely mobile environment where class participants are located inside ad-hoc networks. Features of this application include :Class presenceAudio/Video conferencingInstant messagingInstant message loggingPresentation slides with remote pointerMulticast whiteboardWebcast viewingShared folderOnline error/bug reportingScreenshots of Mobile Classroom during its testing period are available here.
