packets till have a well-defined minimum departure rate.
Assured Forwarding (AF) PHB [RFC 2597] used to offer different levels of
forwarding assurances for packets belonging to an aggregated flow. Each AF
group is independently allocated forwarding resources.
T NERA: By design, the following PHBs
and PHB groups are supported:
• Best Effort (BE) PHB
• Critical Data (CD) PHB
• Real Time Video Conferencing (RT-
