5.3 QoS & BWM
The total amount of data traffic increases nowadays as the higher demand of mobile applications,
like Game / Chat / VoIP / P2P / Video / Web access. In order to pose new requirements for data
transport, e.g. low latency, low data loss, the entire network must ensure them via a connection service
guarantee.
The main goal of QoS & BWM (Quality of Service and Bandwidth Management) is prioritizing
incoming data, and preventing data loss due to factors such as jitter, delay and dropping. Another
important aspect of QoS is ensuring that prioritizing one data flow doesn't interfere with other data
flows. So, QoS helps to prioritize data as it enters your router. By attaching special identification marks
or headers to incoming packets, QoS determines which queue the packets enter, based on priority. This
is useful when there are certain types of data you want to give higher priority to, such as voice packets
given higher priority than Web data packets.
To utilize your network throughput completely, administrator must define bandwidth control rules
carefully to balance the utilization of network bandwidth for all users to access. It is indeed required
that an access gateway satisfies the requirements of latency‐critical applications, minimum access right
guarantee, fair bandwidth usage for same subscribed condition and flexible bandwidth management.
AMIT Security Gateway provides a Rule‐based QoS to carry out the requirements.
5.3.1 Configuration
AMIT gateways adopt rule‐based approach to define the QoS & BWM function. Before the function
works as expected, some system resources must be allocated correctly in "Configuration" page as
below.
In "Configuration" page, there are some configuration windows for QoS & BWM function. They
Index skipping is used to reserve slots for new function insertion, when required.
