Web Caching
Pemakan traffic terbesar di Internet
 Perlu dilakukan caching secara serius.
Artinya Page yang pernah di ambil, tidak
perlu di ambil ulang.
 ITB saat ini yang mempunyai paling tidak
mempunyai 6-7 Web cache server running
squid di FreeBSD.

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!
