Select a DSCP value

Click any DSCP value on the left to see detailed information

DSCP Quick Reference: EF (46) for voice, AF4x for video, AF3x for critical data, AF2x for transactional data, AF1x for bulk data, DF/CS0 (0) for best effort.

Queuing Mechanism Simulator

See how different queuing mechanisms handle packet prioritization:

Queuing Method:

Voice Packets Processed

Video Packets Processed

Data Packets Processed

Bulk Packets Processed

How it works: Click "Add Random Packet" to generate traffic, then click "Process Next Packet" to see which packet gets transmitted first based on the selected queuing method.

Policing vs Shaping - Token Bucket Demo

Visualize the difference between policing and shaping with the token bucket algorithm:

Traffic Rate: 500 Kbps

Configured Rate (CIR): 1000 Kbps

Policing

Token Bucket

Action: FORWARD

Packets Dropped: 0

Policing: Excess traffic is immediately dropped. No buffering occurs.

Shaping

Token Bucket

Action: FORWARD

Packets Buffered: 0

Shaping: Excess traffic is buffered and delayed. Smoother traffic flow.

Key Difference: Policing drops excess traffic (can cause TCP retransmissions), while shaping buffers it (increases delay but reduces loss).
