3.7.2 Quality of Service
Quality of Service refers to the capability of a network device to provide better service to a selected network traffic.
This is achieved by shaping the traffic and processing higher priority traffic before lower priority traffic.
The Broadband Connection to the Internet is typically the most significant bottleneck of the network. This is where the
high speed LAN (100 Mbps) meets limited broadband bandwidth of few Mbps. Special QoS mechanisms must be built
into routers to ensure that this sudden drop in connectivity speed is taken into account when prioritizing and
transmitting real-time service-related data packets.

3.7.2.1 General
The General screen provides a Quality of Service "wizard" with which you can configure your QoS parameters
according to predefined profiles and in just a few clicks. A chosen QoS profile will automatically define QoS rules,
which you can view and edit in the rest of the QoS tab screens, described later.
Note: Selecting a QoS profile will cause all previous QoS configuration settings to be permanently lost.
Click the QoS tab under Services. The Overview screen appears.
