  1. AI3 IndonesiaActivity Report AI3@ITB.ac.id

  2. Focus • Existing Implemented Infrastructure. • Experience in Building an AII. • Low Cost Technology To Educate Indonesia. Low cost is the real challenge

  3. Our situation • Develop by University • Implemented & Run by Education Sector • Thanks to AI3, WIDE, JCSAT without whom all of these activities never exists!

  4. Outline • Historical Perspective • Current Infrastructure. • Brief overview on our research results in: • physical layer. • Network layer. • Application layer.

  5. Experience in Internet building • January 1993 - Suryono (Texas) install a packet radio 1200bps to LAPAN. • LAPAN 1200bps to BPPT & Internet 64Kbps. • 286 PC as gateway! to connect the whole ITB campus. • Software NOS (running on DOS) as gateway.

  6. Indonesia Topology Jan.1993 Amateur Packet Radio AX.25 at 1200bps Starts from simple equipment We grow the community PC Gateway 286!

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

  8. Typical ITB Campus Net

  9. ITB Today .... • T1 Satelite link to Japan. • 2Mbps link to Indonesia IX. • VSAT TDMA & SCPC to various universities. • 4Mbps Uwave Jakarta-Bandung. • 128 Kbps to Jakarta, Surabaya & Malang. • WaveLAN 2Mbps for Metropolitan Area Network (MAN).

  10. ITB Network Operation Center

  11. Connection to IIX via RadNet Connect to 6 Universities 5 Universities / Research Inst 7 Universities via VSAT TDMA SCPC Connect 3 Universities > 10 educational institutions

  12. Involving students in the process! Key to Success Gives incentives for education! The more people the lower the cost Human Resource Development! Self-financing! Community-base development.

  13. National Policy / Activities • AI3 Indonesia has been connecting 27+ educational institutions to Internet. • AI3 Indonesia is becoming a test bed for Indonesia AII. • AI3 Indonesia actives at National NII policy level at http://n21.ac-id.net/

  14. Results in Physical Layer • Homebrew 2Mbps CDMA. • VSAT TDMA vs. SCPC Network. • Low Cost Access for Schools. • Internet Access for Amateur Radio

  15. VSAT TDMA vs. SCPC • VSAT TDMA 128Kbps Outbound • VSAT TDMA 64Kbps Inbound • VSAT TDMA is not suitable for Internet application (especially Web). • Tune TDM for 40 byte (originally 256byte packet). • Migrate to VSAT SCPC (min) 19.2Kbps.

  16. Homebrew 2Mbps CDMA • Uses Lucent CDMA 2Mbps card 915MHz 250mW. • Run on FreeBSD. • Homebrew antenna (cost ~US$150). • Max. distance 15km (use PA for more). • Most of our high speed MAN using this technology.

  17. Consequences CDMA 2Mbps • bypassing local line. • We promote different alternative for building high speed network.

  18. Homebrew 64-256Kbps packet radio • We are prototyping 64-256Kbps packet radio network in the lab by adnan@itb.ac.id. • AX.25 link layer protocol is used. • GMSK MX 589 one chip modem is used. • We drive the modem via parallel port. • MMIC Minicircuit is being build for transverter.

  19. Block Diagram

  20. Homebrew 64-200Kbps Modem

  21. TX & RX BoardVHF CB Frequency

  22. Low Cost Access for Schools • AX.25 1200bps Packet Radio Network. • Proxy Server. • Dial on Demand for Web & Interactive Internet Access.

  23. IntraNet for High Schools 24 hours Packet Radio E-mail Proxy & Dial-on-Demand for Web on Demand

  24. Soundblaster Modem • PC running Linux • Software Modem Packet Radio for Soundblaster • Connect SB-10 to Radio • Speed 1200-9600bps.

  27. Mobile Computing

  28. IPv6 Test Bed Background : The Internet growth caused there is a need for new generation of IP (Internet Protocol) IPv6 Implementation using INRIA Rocquencourt’s IPv6 Implementation which based on FreeBSD (2.2.2-RELEASE and 2.2.5-RELEASE) The participants are : ITB, (Institut Teknologi Bandung), UNPAR (Universitas Parahyangan), and UNILA (Universitas Lampung) Next step : Expand IPv6 Network in AI3-Indonesia Network Connect to 6Bone Develop IPv6 Applications

  30. Exotick:A Single-User Network Operating System Based By Joko Yuliantoro <jky@itb.ac.id> Computer Network Research Group ITB

  31. Traditional Kernel Design • Full Hardware Abstraction. • Centralized Resource Management. • Protection Mechanism / Multiplexing Raw Hardware.

  32. Hardware Abstraction • Large coverage to make it useful to all applications. • Planned to accommodate all interfaces from application to hardware resources. • Trapped in vast small details that make the abstraction composed of inefficient codes and routines.

  33. Impact on Kernel • Large Kernel Size. • Complex Algorithm. • Unreliable. • Inflexible. • Hard global optimization since too many codes and routines are affected.

  34. Impact on Applications • Inefficient. • Complex Algorithm. • Can not grealty improve the efficiency since many details have been hidden away from application.

  35. Exokernel Prototype Design • Created and introduced by Dawson R. Engler and M. Frans Kaashoek from MIT in January 1995. • Main principle is application should manage all physical resources. • Exokernel should only manage resources to the extent required by protection.

  36. Exokernel Prototype Design • Use distributed resource management. • Exokernel concentrate on multiplexing raw hardware.

  37. Exotick • A single-user network operating system based on Exokernel design. • As a start, planned to be a simple TCP/IP router. • Focus on: • Simple operation & programming. • Smaller kernel size. • Fast response (real time).

  38. Exotick • Use Assembler language for best size and speed fulfillment. • Use Netwide Assembler (NASM) version 0.97 as the compiler and linker.

  39. Exotick’s Feature • 32-bit OS on Intel’s architecture. • Preemptive multitasking. • Flat memory model. • Small kernel size. • Fast response (real time). • Plain text user interface. • TCP/IP support.

  40. Exotick Project Status • The project has been started since August 1998. • The project will be completed by the end of 1998.

  41. Results in Network Layer • Network Monitoring by ismail@cnrg.itb.ac.id. • Monitor at http://netmon.itb.ac.id/ • Network Map • Sample of traffic by protocol, port, etc. • Graph of total traffic.

  42. Traffic Distribution Grapher Describes: • Comparison between Inbound and Outbound Traffic • Traffic Distribution by Protocols • The Most Active Routers/Hosts by Protocols • Daily Usage Trend for some Protocols • WeeklyProtocol Usage Trend

  43. TDG URL: http://netmon.itb.ac.id/ In vs Out Host Protokol Trend

  44. Benefits: • Behaviour of the users in ITB (AI3): • Subjects of interest • Sites to be visited • The rush hours • Most actives computer/host • Planning the traffic routing, firewalling, etc.
