Institute of Technology Bandung

3 Major IX but talk no BGP :-(

Institute of Technology Bandung ITB de factor major ISP for Education in Indonesia

Institute of Technology Bandung More Than Half Educational Institutions Are Connected to ITB

Institute of Technology Bandung

Connection to Telkom IX

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

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 Kbps packet radio n We are prototyping Kbps packet radio network in the lab by 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 bps Packet Radio Network. n Proxy Server. n Dial on Demand for Web & Interactive Internet Access.

Institute of Technology Bandung

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 n Monitor at Network Map Sample of traffic by protocol, port, etc. Graph of total traffic. n Migration to OSPF for internal routing.

Institute of Technology Bandung

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 n Uses to teach SGML for technical writting. n will start September n In collaboration with Prof. Paul Beam, University of Waterloo, Canada -

Institute of Technology Bandung Homepage for Network Beginner n check out n Materials on: Satellite Technology. Packet Radio Technology. Tools to integrate Novell to Internet. n Some materials can be downloaded via via .

Institute of Technology Bandung Cache n ITB has set 4 Parents. n Cache person is n We cache all of our Web traffic. n May be our cache machine is the bottleneck. n check out

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.

Institute of Technology Bandung Thank You.
