Appendix G: Bandwidth Management with QoS
G.1 Overview
In a home or office environment, users constantly have to transmit data to and from
the Internet. When too many are accessing the Internet at the same time, service
can slow to a crawl, causing service interruptions and general frustration. Quality of
Service (QoS) is one of the ways BiGuard 30 can optimize the use of bandwidth,
ensuring a smooth and responsive Internet connection for all users.
G.2 What is Quality of Service?
QoS is a feature that prioritizes and guarantees bandwidth to achieve optimal
service performance. QoS can maximize the use of available network bandwidth by
prioritizing time-sensitive traffic to avoid latencies and delays. By ensuring that
time-sensitive applications such as VoIP and streaming video get priority access to
bandwidth, users in both home and office environments can enjoy smooth and
responsive data transmission no matter which applications they are running.
If you’ve ever experienced slow Internet speeds due to other network users using
bandwidth-consuming applications like P2P, you’ll understand why QoS is such a
breakthrough for home users and office users. Billion makes itself unique by
integrating QoS in its routers for both inbound and outbound traffic.
QoS helps users manage bandwidth and effectively prioritize data traffic. It gives
you full control over the traffic of any type of data. Employed on DiffServ
(Differentiated Services) architecture, data traffic is given priority by the router;
ensuring latency-sensitive applications like voice and mission-critical data such as
VPN move through the router at lightning speeds, even under heavy load. You can
throttle the speed of different types of data passing through the router, limit the
speed of unimportant or bandwidth-consuming applications, and even distribute the
bandwidth for different groups of users at home or in the office. QoS keeps your
Internet connection smooth and responsive.
G.3 How Does QoS Work?
QoS employs three different methods for optimizing bandwidth:
