AI3 IndonesiaActivity Report
  • AI3_at_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).

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

14
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/

15
Results in Physical Layer
  • Homebrew 2Mbps CDMA.
  • VSAT TDMA vs. SCPC Network.
  • Low Cost Access for Schools.
  • Internet Access for Amateur Radio

16
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.

17
Homebrew 2Mbps CDMA
  • Uses Lucent CDMA 2Mbps card 915MHz 250mW.
  • Run on FreeBSD.
  • Homebrew antenna (cost US150).
  • Max. distance 15km (use PA for more).
  • Most of our high speed MAN using this technology.

  • We promote different alternative for building
    high speed network.

20
Homebrew 64-256Kbps packet radio
  • We are prototyping 64-256Kbps packet radio
    network in the lab by adnan_at_itb.ac.id.

  • Background The Internet growth caused there
    is a need for new
  • generation of IP (Internet Protocol)
  • IPv6 Implementation using INRIA Rocquencourts
    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)

ExotickA Single-User Network Operating System
Based
  • By
  • Joko Yuliantoro ltjky_at_itb.ac.idgt
  • Computer Network Research Group ITB

36
Traditional Kernel Design
  • Full Hardware Abstraction.
  • Centralized Resource Management.
  • Protection Mechanism / Multiplexing Raw Hardware.

37
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.

38
Impact on Kernel
  • Large Kernel Size.
  • Complex Algorithm.
  • Unreliable.
  • Inflexible.
  • Hard global optimization since too many codes and
    routines are affected.

39
Impact on Applications
  • Inefficient.
  • Complex Algorithm.
  • Can not grealty improve the efficiency since many
    details have been hidden away from application.

40
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.

41
Exokernel Prototype Design
  • Use distributed resource management.
  • Exokernel concentrate on multiplexing raw
    hardware.

42
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).

43
Exotick
  • Use Assembler language for best size and speed
    fulfillment.
  • Use Netwide Assembler (NASM) version 0.97 as the
    compiler and linker.

44
Exoticks Feature
  • 32-bit OS on Intels architecture.
  • Preemptive multitasking.
  • Flat memory model.
  • Small kernel size.
  • Fast response (real time).
  • Plain text user interface.
  • TCP/IP support.

45
Exotick Project Status
  • The project has been started since August 1998.
  • The project will be completed by the end of 1998.

46
Results in Network Layer
  • Network Monitoring by ismail_at_cnrg.itb.ac.id.
  • Monitor at http//netmon.itb.ac.id/
  • Network Map
  • Sample of traffic by protocol, port, etc.
  • Graph of total traffic.

47
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
  • Weekly Protocol Usage Trend

Results in Application Layer
  • Mailing Lists
  • English Technical Writting Course distance
    learning test bed.
  • Cache Cache Monitoring.
  • MPEG-3 Test Bed.
  • RealPublisher NetShow test bed.

59
Cache
  • ITB has set several Parents cache.
  • Cache person is husni_at_itb.ac.id
  • We cache all of our Web traffic.
  • check out http//www.lp.itb.ac.id/cacher/

60
HTTP-Cache What
  • Use of Proxy Server
  • Previously fetched WWW objects are stored in
    Proxy Server
  • Proxy Server gives cached WWW object instead of
    fetches it from WWW server
  • Use of non-persistent caching

61
HTTP-Cache Why
  • Web is the most popular application on The Net
  • Web traffic in byte is about 40
  • WAN link get congested
  • Most WWW objects are static

62
HTTP-Cache Facts
  • HTTP-Cache reduces WAN traffic
  • More Effective than Server mirror

63
Cache Hierarchy
  • Cache-Server mesh
  • Collaborates using parent-sibling relationship
  • Sibling fetches WWW-object only if it is found
    in local cache
  • Parent always fetches requested WWW-object

64
Cache Hierarchy at ITB Network
65
Cache Usage Monitoring
  • Log files
  • Daily statistics
  • Web-based report

69
Results
  • Over 1.5Gbytes transferred data at a normal
    work-day
  • Over 400Mbytes transferred data at a weekend-day
  • Reduces upto 19 in HTTP traffic

70
Typical Cache Results
  • Hit requests 53.90
  • Hit bytes 38.79
  • Total requests 406.473
  • Total successfull requests 406.473
  • Average requests /day 695.980
  • Total bytes 582.499.684
  • Average bytes / day 997.383.525

71

  • Run on Dual Pentium 166MHz 32Mb RAM.
  • More than 220 mailing lists at ITB. (more than
    75 Indonesian mailing lists).
