  • QOSmerupakancara yang digunakanuntukmengaturpenggunaan bandwidth yang adasecararasional.

  • QOSbisadigunakanjugauntukmengaturprioritasberdasarkan parameter yang diberikan,

  • Pengaturaninidilakukandengancaracara buffering (menahansementara), ataukalaumelampaui limit buffer, akandilakukan drop padapakettersebut.

  • Pada TCP, paket yang didropakandilakukanpengirimanulang agar tidakterjadikehilanganpaket data.

  • Cara yang paling mudahdalammenggunakanQOSadalahmenggunakan simple queue

Staged limitation

STAGED LIMITATION

  • PadaRouterOS, dikenal 2 buah limit:

    • CIR (Committed Information Rate)

    • MIR (Maximal Information Rate)

BURST

  • Burst adalahsalahsatucaramenjalankanQoS

  • Burst memungkinkanpenggunaan data-rate yang melebihi max-limit untukperiodewaktutertentu

  • Jika data rate lebihkecildariburst-threshold, burst dapatdilakukanhingga data-rate mencapaiburst-limit

BURST

  • Setiapdetik, router mengkalkulasi data rate rata-rata padasuatu queue untukperiodewaktuterakhirsesuaidenganburst-time

  • Burst time tidaksamadenganwaktu yang diijinkanuntukmelakukan burst.

Queue type

QUEUE TYPE

  • Queue Scheduler

    • BFIFO (Bytes First-In First-Out)

    • PFIFO (Packets First-In First-Out)

    • RED (Random Early Detect)

    • SFQ (Stochastic Fairness Queuing)

  • Shaper queues

    • PCQ (Per Connection Queue)

    • HTB (Hierarchical Token Bucket)

  • Per Connection Queuing digunakanuntukmenyederhanakanaturan queue, daribeberapaaturanmenjadisatu

  • Mengaturpembatasan yang samauntuk user manapun

  • Menyamakanpenggunaan bandwidth yang samabagisetiap user

Equalize bandwidth

EQUALIZE BANDWIDTH

  • Equalize bandwithadalahmemberikanbatasan total bandwidth yang dibagi rata bagisemua user. Contohberikutmenunjukkankonfigurasibahwaada total bandwidth sebesar128kuntuk download dan512kuntuk download, yang harusdibagimeratabagisemua user.
