Institute of Technology Bandung What AI3 has done to Indonesia Onno W. Purbo Institute of Technology Bandung Bandung, Indonesia June 1997
Institute of Technology Bandung Outline n Indonesia Internet Topology. n Indonesia Education Network. n Brief results in Physical layer. n Brief results in Network layer. n Brief results in Application layer. n Summary.
Institute of Technology Bandung 7 Universities via VSAT TDMA
Institute of Technology Bandung New Installation Will Connect 3 Universities
Institute of Technology Bandung Connect to 6 Universities
Institute of Technology Bandung 5 Universities / Research Inst
Institute of Technology Bandung > 10 educational institutions
Institute of Technology Bandung Results in Physical Layer n Homebrew 2Mbps CDMA. n Wireless Data Network. n VSAT TDMA vs. SCPC Network. n Fast Ethernet Test Bed. n Low Cost Access for Schools.
Institute of Technology Bandung Homebrew 2Mbps CDMA n Uses Lucent CDMA 2Mbps card 915MHz 250mW. n Run on FreeBSD. n Homebrew antenna (cost ~US$150). n Max. distance 15km (use PA for more). n Most of our high speed MAN using this technology. n contact email@example.com.
Institute of Technology Bandung Consequences CDMA2Mbps n bypassing local line. n FYI, Indonesia currently have only 300 N-ISDN lines in operation. n We promote diffierent alternative for building high speed network.
Institute of Technology Bandung Wireless Data Network n DataTAC 19.2Kbps WIreless Data Network
Institute of Technology Bandung Wireless Data Network n DataTAC Wireless Data Network at 19.2Kbps. n Internet Access. n Interface to FAX. n Interface to Pagers. n Interface to Short Message Services (SMS)
Institute of Technology Bandung Homebrew 64-256Kbps packet radio n We are prototyping 64-256Kbps packet radio network in the lab by firstname.lastname@example.org. n AX.25 link layer protocol is used. n GMSK MX 586 one chip modem is used. n We drive the modem via parallel port. n MMIC Minicircuit is being build for transverter.
Institute of Technology Bandung Fast Ethernet Test Bed n Supported by Intel. n Test Intel Fast Ethernet board to run on FreeBSD. n This test bed is driven by our overloaded MPEG-3 traffic :-)....
Institute of Technology Bandung Low Cost Access for Schools n AX.25 1200bps Packet Radio Network. n Proxy Server. n Dial on Demand for Web & Interactive Internet Access.
VSAT TDMA vs. SCPC n VSAT TDMA 128Kbps Outbound n VSAT TDMA 64Kbps Inbound n VSAT TDMA is not suitable for Internet application (especially Web). n Tune TDM for 40 byte (originally 256byte packet). n Migrating to VSAT SCPC 19.2Kbps at least.
Institute of Technology Bandung Results in Network Layer n Network Monitoring by email@example.com. n Monitor at http://netmon.itb.ac.id/ Network Map Sample of traffic by protocol, port, etc. Graph of total traffic. n Migration to OSPF for internal routing.
Results in Application Layer n Mailing Lists n Homepage for Network Beginners. n English Technical Writting Course distance learning test bed. n Cache & Cache Monitoring. n MPEG-3 Test Bed. n Java Test Bed.
Institute of Technology Bandung Java Test Bed n Supported by Sun Microsystem & Intel. n Only last 2 week,they provide the public domain software, documentation. n No machine is dedicated to it yet. n We are still learning on how to program Java.
Institute of Technology Bandung English Technical Writting Course n Web based distance learning, with chat & newsgroup. n URL http://itrc.uwaterloo.ca/~engl210e/ n Uses to teach SGML for technical writting. n will start September 1997. n In collaboration with Prof. Paul Beam, University of Waterloo, Canada - firstname.lastname@example.org.
Institute of Technology Bandung Homepage for Network Beginner n check out http://www.lp.itb.ac.id/~yc1dav/beginner/ n Materials on: Satellite Technology. Packet Radio Technology. Tools to integrate Novell to Internet. n Some materials can be downloaded via Majordomo@itb.ac.id via E-mail.
Institute of Technology Bandung Cache n ITB has set 4 Parents. n Cache person is email@example.com n We cache all of our Web traffic. n May be our cache machine is the bottleneck. n check out http://www.lp.itb.ac.id/~cacher/
Institute of Technology Bandung Mailing Lists n Uses majordomo on FreeBSD n Run on Pentium 166MHz 32Mb RAM n >150 mailing lists at ITB. (more than 75% Indonesian mailing lists). n More than 5000 subscribers. n We are trying to build the community in Indonesia.
