3.4.3 QoS
Quality of Service (QoS) refers to the capability of a network to provide better service to
selected network traffic over various technologies, including Frame Relay, Asynchronous
Transfer Mode (ATM), Ethernet and 802.1x networks, and IP-routed networks that may use
any or all of these underlying technologies. The primary goal of QoS is to provide priority
including dedicated bandwidth, controlled jitter and latency (required by some real-time and
interactive traffic), and improved loss characteristics. Also important is making sure that
providing priority for one or more flows does not make other flows fail. QoS technologies
provide the elemental building blocks that will be used for future business applications in
campus, WAN and service provider networks. This chapter provides each setting of QoS.
1. Enable QoS Service:
One checkbox appears to activate the QoS control function or
not. Click it to force the router to perform QoS control over traffic flows. By default, it’s
enabled.
2.
Current Upstream Bandwidth:
Allows you to set the upper bound of the port
forwarding rate. It will be of great value to minimize the impact on other users from one
user who would otherwise monopolize the network transmission bandwidth (e.g.
playing games or downloading large files).
3.
Priority:
To limit the bandwidth consumed over a backbone link by FTP transfers or
give priority to an important database access. And the following applications can be
selected individually and distribute the priority level.
4. Application:
Including FTP, HTTP, E-mail, Telnet, Voice, Games, IM and Video priority
setting.
