-Prioritization: Assigns different priority levels for different applications, prioritizing 
traffic. High, Normal and Low priority settings. 
-Outbound and Inbound IP Throttling: Controls network traffic and allows you to 
limit the speed of each application. 
-DiffServ Technology: Manages priority queues and DSCP tagging through the 
Internet backbone. Manages traffic among Ethernet, wireless, and ADSL interfaces. 
 
G.4  Who Needs QoS? 
QoS is ideal for home and office users who need to use a variety of real-time 
applications like VoIP, on-line games, P2P, video streaming, and FTP simultaneously. 
With QoS, you can optimize your bandwidth to accommodate several of these 
applications without experiencing latency or service interruptions. 
 
G.4.1  Home Users 
 
Low latency is everything for gamers. Most home users feel frustrated when trying 
to play an online game over a shared ADSL connection. Unfortunately, most routers 
have no way of determining the importance of the packet at any given time. All the 
traffic is treated equally, so a packet containing an "urgent" command may be 
delayed. QoS gives you the ability to control the bandwidth. Using IP Throttling, 
bandwidth limits can be enforced on a particular application or any system within 
the LAN. Prioritization specifies which packets have priority and should not be 
delayed, and which packets have lower priority and should be moved to the end of 
the upload queue. 
 
Suppose there are four students sharing a three-floor house with one single 
broadband connection. Tom, a college freshman, is playing the online game with his 
group members, while Mary, a sophomore student, is talking to her net pal via 
Skype. Meanwhile, Jacky is downloading a movie file by using the P2P application 
program. Sophia, however, is just trying to log on to the website to send her photos 
to her family. As a result, the net speed slows to a crawl and affects everyone 
sharing the Internet connection. QoS is designed for managing traffic flow and 
bandwidth to solve this problem. You can first classify different applications (online 
games, FTP, Skype, email) as shown in the table below. Then, you can manage and 
prioritize the flow of bandwidth at different levels (e.g. 30% for games, 20% for 
downloads, 10% for email, 20% for FTP, and 35% for others). QoS can be used to 
identify different applications and assign priority to enable a smooth and responsive 
broadband connection.
