  2. 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.

  3. Indonesia Topology Jan.1993 Amateur Packet Radio AX.25 at 1200bps Start from simple equipment We grow the community PC Gateway 286!

  4. ITB Today .... • T1 Satelite Link to Japan. • Installation of 2Mbps to IIX. • VSAT TDMA & SCPC to various universities. • 4Mbps Uwave Jakarta-Bandung. • ISDN Line di Jakarta. • WaveLAN 2Mbps for Metropolitan Area Network (MAN). Homebrew 2Mbps MAN!

  5. Connection to IIX via RadNet Connect to 6 Universities 5 Universities / Research Inst 7 Universities via VSAT TDMA SCPC Connect 3 Universities > 10 educational institutions

  6. Cara Paling Ekonomis? • Internet baru akan menguntungkan jika berlangganan secara kolektif. • Satu kampus dapat dihubungkan ke Internet dengan satu buah leased-line / saluran komunikasi. • Biaya berlangganan bagi 6-10 orang / bulan bisa membiayai langganan satu kampus selama satu bulan! Seringkali Kita Tidak Menyadari Hal ini

  7. Frequently Asked Questions? • Bagaimana cara menyambungkan sebuah Corporate Wide Area Network? • Peralatan apa saja yang dibutuhkan? • Bagaimana konfigurasi peralatan tersebut?

  8. VSAT TDMAUS$ 1500 / month 64Kbps VSAT SCPC US$4000 / m 64Kbps LAN Di Dalam Universitas Tidak Perlu di Ubah ITB: Server Novell dengan 2 Card Ethernet - sebagai Router Hanya Perlu Penambahan Software Internet Corporate / Campus Internet Di rancang Backbone Dalam Gedung / Kampus Bisa Memilih Antara 3 Alternatif IP Dari ISP hanya beberapa buah saja Kampus Network di balik Firewall Menggunakan Kelas A 10.x.x.x Firewall / Proxy 486/586 Untuk: Security & Penghematan IP Address WaveLAN 2Mbps - 15 km US$4000 / node Open Network Tempat Meletakan Mesin Public Sewa Leased Line Telkom / Lintasarta
