[JUNOS] Class of Service – Queuing and Scheduling

 

CoS Process

 

Why we need Queuing process and when we use it?

Queuing and scheduling control the prioritization of traffic flows

    <> Queue priority – which forwarding class (FC) gets more/less access to the outbound interface

    <> Transmission rate – how much bandwidth each FC gets.

    <> Delay buffer – how many packets can be held during congestion

    <> Congestion management – which flows get dropped during congestion.
