traffic managementprioritizationnetwork optimization
A set of technologies and techniques used to manage and prioritize network traffic, ensuring better performance for critical applications.
Examples
Home router QoS
Prioritize gaming console traffic over file downloads
Business network
VoIP calls get priority over email traffic
Common Misconceptions
- •QoS can't create more bandwidth - it only manages existing bandwidth
- •QoS settings vary greatly between router models
Optimization Tips
Prioritize real-time applications (gaming, VoIP)
Set bandwidth limits for non-critical devices
Use device-based rather than application-based rules
User Impact
Gaming
Reduces lag when others are using network
Video calls
Maintains call quality during network congestion
Streaming
Prevents buffering when network is busy
Troubleshooting
Issue: QoS not working
Solution: Verify settings match device MAC addresses
Issue: Over-restriction
Solution: Adjust bandwidth allocations, avoid too strict limits
Technical Details
Specification: Uses DSCP markings, traffic shaping, and packet scheduling
