Default traffic allocation dalam Juniper Router itu 1:19, alias 95:5

95% traffic untuk Best Effort (BE) dan 5% traffic sisa untuk Network Control (NC)

(mungkin lo harus nyebrang2 artikel dulu untuk liat best-effort dan network control dalam QoS itu apa dan gunanya apa)

Link ane

Dalam juniper, BE dan NC ini adalah 2 dari 4 forwarding-class yang bisa dikonfig

Lets see the “show class-of-service”

Ada BE, NC, AF (Assured-Forwarding), dan EF (Expedited-Forwarding)

If you familiar with AF31, AF42,atau EF…yup…this is DSCP (differentiated service code point)

=======================================

Setting CoS (Class of Service) for specific address(es)

Contoh kita pengen LAN kita (10.0.0.0) pake CoS EF

First, create the rule…firewall rule

Jgn lupa yang laen juga (implicit deny/silent discard soalnya nanti)

The show

Second, apply to the interface (the logics are same right?!?)

Eh…kita settingnya kan pake Expedited Forwarding, dapet brp bandwidth tuh?? Kan blum diset ??

Bisa ga di rubah untuk BE 20%, AF 30%, EF 40%, dan NC 10% ??

Bisa…nyok kita setting

======================

Changing Class-of-Service priority bandwidth between Queue

First, create CUSTOM MAPPING for CoS

Lets see the show

Second, we DEFINE that custom mapping (CUSTOM-BE and his friends)

Third, set the interface that we want to apply that Custom CoS Mapping

And here’s the complete configuration

====================================

Andddd…by the way…kita bisa kasi nama buat masing2 queue loh

Trus klo mau kasi custom dscp trus apply ke interface gimana?? (ini bukan basic lagi namanya -_-; )

Trus masukin ke interface (di hierarki class-of-service, bukan di interfacenya)
