memanage bandwith warnet kita

Warung internet atau yang akrab disebut warnet merupakan lapak yang bagus bagi para freelance Nerwork engineer. Namun berbisnis warung internet saja tidak cukup jika hanya sekedar melepas jaringan pada suatu perangkat computer saja tanpa memikirkan kualitas dan tehnik yang digunakan untuk melepas jaringan pada setiap perangkat computer. Apalagi warnet tersebut tidak hanya menyediakan fasilitas browing semata ada pula warnet yang dilengkapi fasilitas Game Online atau biasa disebut Game Center

Cara-cara pengoptimalan jaringan internet warnet kita:

Settingan ini tidak bermain port game melainkan memisahkan IP game via Nice, yang mana IP yang tidak ada di nice list di lewatkan di speedy 1 nya.

2. MEMBAGI PORT GAME ONLINE
Untuk sebuah warnet yang juga menyediakan game online ternyata lebih optimal dengan Bandwith Management menggunakan methode Simple Queue. Dengan Simple queue kita cukup me mangle setiap ip/port game online dan seterusnya di queue diberikan limit bandwith yang lebih besar atau unlimited saja dan prioritaskan paling tinggi.
