Results in Physical Layer

 Homebrew 2Mbps CDMA.

 Wireless Data Network.

 VSAT TDMA vs. SCPC Network.

 Fast Ethernet Test Bed.

(15)

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.

(16)

Consequences CDMA2Mbps

 bypassing local line.

 FYI, Indonesia currently have only 300

N-ISDN lines in operation.

 We promote diffierent alternative for

(17)

Wireless Data Network

 DataTAC 19.2Kbps WIreless Data

(18)

Wireless Data Network

 DataTAC Wireless Data Network at

19.2Kbps.

 Internet Access.

 Interface to FAX.

 Interface to Pagers.

 Interface to Short Message Services

(19)

Homebrew 64-256Kbps packet

radio

 We are prototyping 64-256Kbps packet radio network in the lab by

[email protected].

 AX.25 link layer protocol is used.

 GMSK MX 586 one chip modem is used.

 We drive the modem via parallel port.

(20)

Fast Ethernet Test Bed

 Supported by Intel.

 Test Intel Fast Ethernet board to run on

FreeBSD.

 This test bed is driven by our

Low Cost Access for Schools

 AX.25 1200bps Packet Radio Network.

 Proxy Server.

 Dial on Demand for Web & Interactive

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).

(24)

Results in Network Layer

 Network Monitoring by

[email protected].

 Monitor at http://netmon.itb.ac.id/

• _{Network Map}

• Sample of traffic by protocol, port, etc.

• _{Graph of total traffic.}

Results in Application Layer

 Mailing Lists

 Homepage for Network Beginners.

 English Technical Writting Course

distance learning test bed.

 Cache & Cache Monitoring.

 MPEG-3 Test Bed.

(29)

Java Test Bed

 Supported by Sun Microsystem & Intel.

 Only last 2 week,they provide the public

domain software, documentation.

 No machine is dedicated to it yet.

 We are still learning on how to program

(30)

English Technical Writting

Course

 Web based distance learning, with chat & newsgroup.

 URL http://itrc.uwaterloo.ca/~engl210e/

 Uses to teach SGML for technical writting.

 will start September 1997.

 In collaboration with Prof. Paul Beam, University of Waterloo, Canada -

(31)

Homepage for Network Beginner

 check out

http://www.lp.itb.ac.id/~yc1dav/beginner/

 Materials on:

• Satellite Technology.

• Packet Radio Technology.

• Tools to integrate Novell to Internet.

 Some materials can be downloaded via

Cache

 ITB has set 4 Parents.

 Cache person is [email protected]

 We cache all of our Web traffic.

 May be our cache machine is the

bottleneck.

 check out

(33)

Mailing Lists

 Uses majordomo on FreeBSD

 Run on Pentium 166MHz 32Mb RAM

 >150 mailing lists at ITB. (more than

75% Indonesian mailing lists).

 More than 5000 subscribers.

 We are trying to build the community in
