OUTLINE

  •	The Indonesia TCP/IP packet radio computer network.
	  	network topology
	  	network architecture (TCP/IP)
	  	software and hardware configuration

  •	Integration into satellite network.

  •	Proposed experimental work.

SOFTWARE AND HARDWARE CONFIGURATION

  •	Software configuration:
	  	NetBSD or 386BSD
	  	KA9Q TCP/IP Network Operating System

  •	Satellite Router Hardware configuration:
	  	PC 486 running NetBSD or 386BSD
	  	Two (2) serial ports
			38.4Kbps SLIP to ETS-V.
			9600bps SLIP to packet radio gateway.

  •	Packet Radio Gateway Hardware configuration:
	  	PC 286 running KA9Q NOS
	  	Two (2) serial ports
			9600bps SLIP to Satellite Router.
			1200bps packet radio equipment.
	  	Ethernet to Local Area Network

  •	Packet radio equipment.
	  	Terminal Node Controller
		HDLC AX.25
	  	VHF Transceiver

INTEGRATION INTO SATELLITE NETWORK

  •	Current experiment configuration with single client connected to the satellite hub is inefficient since networking is very popular in Indonesia and so many people is interested to peek into the InterNet :-) ...
	all within the precious seven (7) hours :-( ...

  •	If there is a possibility to integrate the client ETS-V machine in Indonesia into the Indonesia packet radio computer network - will be more people in Indonesia exposed to ETS-V satellite link!

PROPOSED EXPERIMENTAL WORK

  •	Experimental configuration

  •	Use of Routing Information Protocol (RIP)

  •	Applications
	  	File Transfer
	  	Network News Transfer Protocol
	  	Gopher / database access.

SUMMARY

  •	The current packet radio network topology is described.

  •	Integration into satellite network is proposed.

  •	Experimental method as well as the application integrated satellite and terrestrial network is described.
