  • Existing Implemented Infrastructure.

  • Experience in Building an AII.

  • Low Cost Technology To Educate Indonesia.

Low cost is the real challenge

Our situation
Our situation

  • Develop by University

  • Implemented & Run by Education Sector

  • Thanks to AI3, WIDE, JCSAT without whom all of these activities never exists!


  • Historical Perspective

  • Current Infrastructure.

  • Brief overview on our research results in:

    • physical layer.

    • Network layer.

    • Application layer.

Experience in internet building
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.

  • 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).

Ipv6 test bed

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

Traditional kernel design
Traditional Kernel Design

  • Full Hardware Abstraction.

  • Centralized Resource Management.

  • Protection Mechanism / Multiplexing Raw Hardware.

Hardware abstraction
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.

Impact on kernel
Impact on Kernel

  • Large Kernel Size.

  • Complex Algorithm.

  • Unreliable.

  • Inflexible.

  • Hard global optimization since too many codes and routines are affected.

Impact on applications
Impact on Applications

  • Inefficient.

  • Complex Algorithm.

  • Can not grealty improve the efficiency since many details have been hidden away from application.

Exokernel prototype design
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.

Exokernel prototype design1
Exokernel Prototype Design

  • Use distributed resource management.

  • Exokernel concentrate on multiplexing raw hardware.


  • 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).


  • Use Assembler language for best size and speed fulfillment.

  • Use Netwide Assembler (NASM) version 0.97 as the compiler and linker.

Exotick s feature
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.

Exotick project status
Exotick Project Status

  • The project has been started since August 1998.

  • The project will be completed by the end of 1998.

  • ITB has set several Parents cache.

  • Cache person is

  • We cache all of our Web traffic.

  • check out

Http cache what
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

Http cache why
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

Http cache facts
HTTP-Cache: Facts

  • HTTP-Cache reduces WAN traffic

  • More Effective than Server mirror

Cache hierarchy
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

Cache usage monitoring
Cache Usage Monitoring

  • Log files

  • Daily statistics

  • Web-based report


  • Over 1.5Gbytes transferred data at a normal work-day

  • Over 400Mbytes transferred data at a weekend-day

  • Reduces upto 19% in HTTP traffic

Typical cache results
Typical Cache Results

  • Hit requests 53.90%
