Appendix C: Bandwidth Management with QoS

C.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 MH-1000 can optimize the
use of bandwidth, ensuring a smooth and responsive Internet connection for all users.
C.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.
PLANET 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.
C.3 What is Quality of Service?
QoS employs three different methods for optimizing bandwidth:
- 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.
C.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.
