Qos—Mapping Flows to Desired CoS

• High Priority = Highest Priority
• Best Effort = Medium Priority
• Low Priority = Lowest Priority

• Always Drop
  • Means the firewall drops all packets in excess of the specified rate limit
• Congested Drop
  • Excess packets receive the same priority as non-excess but are dropped on congestion
• Low Priority
  • Excess packets are deprioritized to the low priority queue
• Congestion Detection
  • Excess packets will be scheduled using Random Early Detection (RED)
