A COMPULSORY DECISION

PROBLEM

4. QOS
GRADES OF PRIORITY DEPENDING
ON THE KIND OF TRAFFIC
• Our phones need
higher bit rates
• Nets and devices
have to improve
• We want video and
music streaming

5. HIDE WEAK POINTS OF THE NET TO THE
USER
MAKE USERS THINK THAT IT WORKS QUITE
WELL
AIM

6. IF WHEN A USER…
HOW CAN WE DO IT?
• Make an IP phone
call, there are no
delays
• Watch a video, it
doesn´t stop after
having started
• Net works well!

7. IT DOES NOT MATTER IF A WEB PAGE NEEDS
0.8 OR 1.2 SECONDS TO BE SHOWN
HOWEVER

8. SO
PACKAGES MUST BE MARKED, AND ROUTERS
SHOULD DECIDE WHAT PACKAGE PASS FIRST

9. IT IS CLOSE TO THE IDEA OF STREET LIGHTS
AND SPEED LIMITS IN DIFFERENT ROADS

10. QUALITY OF SERVICE MUST BE IMPLEMENTED
IN ORDER TO AVOID WASTING RESOURCES
WHICH IS SOMETHING
CRITICAL TO AN ENGINEER
