In an eleven-class queueing model following Realtime. Best effort, and scavenger queuing rules. What recommended percentage of bandwidth must be allocated for interactive video?

10% is a common recommendation for voice traffic (EF) but is generally considered insufficient for interactive video in an eleven-class model.

12% is not a standard recommended bandwidth allocation for interactive video in Cisco's eleven-class QoS model.

Cisco's QoS design guidelines for an eleven-class model typically recommend allocating 15% of the available bandwidth for interactive video traffic (AF41). This ensures sufficient resources for real-time video applications to maintain quality and minimize latency and jitter.

20% bandwidth allocation for interactive video might be excessive and could starve other critical applications, as 15% is the generally recommended maximum for this class.
