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 2.2.5RELEASE)
 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

Computer Network Research
Group ITB
Traditional Kernel Design
Full Hardware Abstraction.
Centralized Resource Management.
Protection Mechanism / Multiplexing Raw
Hardware.
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
Large Kernel Size.
Complex Algorithm.
Unreliable.
Inflexible.
Hard global optimization since too many
codes and routines are affected.
Impact on Applications
Inefficient.
Complex Algorithm.
Can not grealty improve the efficiency
since many details have been hidden
away from application.
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
Design
Use distributed resource management.
Exokernel concentrate on multiplexing raw
hardware.
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).
Exotick
Use Assembler language for best size and
speed fulfillment.
Use Netwide Assembler (NASM) version
0.97 as the compiler and linker.
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
The project has been started since August
1998.
The project will be completed by the end
of 1998.

Cache
ITB has set several Parents cache.
Cache person is [email protected]
We cache all of our Web traffic.
check out
http://www.lp.itb.ac.id/~cacher/
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
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 reduces WAN traffic
More Effective than Server mirror
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 WWWobject
