Information Technology for Indonesian Education Network Computer Network Research Group Institute of Technology Bandung

Focus zExisting Implemented Infrastructure. zExperience in Building an AII. zLow Cost Technology To Educate Indonesia.

Our situation zDevelop by University zImplemented & Run by Education Sector zFor Indonesia ….

Outline zHistorical Perspective zCurrent Infrastructure. zBrief overview on our research results in: yphysical layer. yNetwork layer. yApplication layer.

Experience in Internet building zJanuary Suryono (Texas) install a packet radio 1200bps to LAPAN. zLAPAN 1200bps to BPPT & Internet 64Kbps. z286 PC as gateway! to connect the whole ITB campus. zSoftware NOS (running on DOS) as gateway.

Indonesia Topology Jan.1993

ITB in 1995 zTelkom Leased Line at 14.4Kbps zRISTI-Telkom to BPPT 64Kbps. zITB uses FreeBSD (UNIX) as Router & Server. zFor the first time ITB sees Web in Internet. zITB learns to build a campus network (how to handle the lightning).

Typical ITB Campus Net

ITB Today.... zT1 Satelite link to Japan. z2Mbps link to Indonesia IX. zVSAT TDMA & SCPC to various universities. z4Mbps Uwave Jakarta-Bandung. z128 Kbps to Jakarta, Surabaya & Malang. zWaveLAN 2Mbps for Metropolitan Area Network (MAN).

ITB Network Operation Center

Key to Success Human Resource Development! Self-financing! Community-base development.

Results in Physical Layer zHomebrew 2Mbps CDMA. zVSAT TDMA vs. SCPC Network. zLow Cost Access for Schools. zInternet Access for Amateur Radio

Homebrew 2Mbps CDMA zUses Lucent CDMA 2Mbps card 915MHz 250mW. zRun on FreeBSD. zHomebrew antenna (cost ~US$150). zMax. distance 15km (use PA for more). zMost of our high speed MAN using this technology.

Homebrew Kbps packet radio zWe are prototyping Kbps packet radio network in the lab by zAX.25 link layer protocol is used. zGMSK MX 589 one chip modem is used. zWe drive the modem via parallel port. zMMIC Minicircuit is being build for transverter.

Mobile Computing

Results in Network Layer zNetwork Monitoring by zMonitor at yNetwork Map ySample of traffic by protocol, port, etc. yGraph of total traffic.

Scotty monitor Web screen

Text Map Timeout alarm to Administrator

Results in Application Layer zMailing Lists zEnglish Technical Writting Course distance learning test bed. zCache & Cache Monitoring. zMPEG-3 Test Bed. zRealPublisher & NetShow test bed.

Cache zITB has set several Parents cache. zCache person is zWe cache all of our Web traffic. zcheck out

Cache Hierarchy at ITB Network

Cache Usage Monitoring zLog files zDaily statistics zWeb-based report

Cache stats: ns1.itb.ac.id

Results zOver 1.5Gbytes transferred data at a normal work-day zOver 400Mbytes transferred data at a weekend-day zReduces upto 19% in HTTP traffic

Mailing Lists zUses majordomo on FreeBSD zRun on Dual Pentium 166MHz 32Mb RAM. zMore than 220 mailing lists at ITB. (more than 75% Indonesian mailing lists). zMore than subscribers. zWe are trying to build the community in Indonesia.

Distance Learning zITB’s Server:

Video Conference z25 October 1997: 14:00 Indonesia Time. zThree Cities: Bandung-Surabaya-Malang zCU-SeeMe & Its Reflector. zAiming for high school network in Indonesia. zJuly 1997: Panel Discussion on the future of higher education (UNU).

Video on Demand zSupported by Microsoft & Progressive Network. zSplitter for UNFCC COP3 December zPublisher for “ITB’s Alumny Congress” December 1997.

Summary zITB has managed to integrate 20+ educational institutions to Internet. zMajor IT used: y2Mbps CDMA Network. yWeb based distance learning. yReal Publisher / Microsoft NetShow. zKey to success: Mass Qualified Human Resource
