BTW itu dari hop 0 ke 1, kita di lingkungan 100 Mbps, walau kalau tidak
salah sih ada satu bagian yang pakai Hub. Mungkin karena ini, jadi hanya
dapat 25 Mbps ya ?
Dari hop 1 ke 2 itu gigabit ethernet, entah full duplex atau half
duplex, wong pakai fiber kok.
Kalau hop ke 2 ke 3 itu ada yang salah rasanya, wong dia dual DS3 kok
(harusnya 90 Mbps). Mungkin pas lagi jam sibuk ya ?
