3.5 Guaranteed Quality of Service

Nowadays if you need a good quality of service, just simply throwing more bandwidth
at your network is not the ultimate solution to this problem, because you can't foresee what
new bandwidth-hungry applications will be in use in several months. An ill-behaved
application can easily bring your network down and potentially shut down your business
operation. To gain more effective control of your network, you need to incorporate Quality of
Service (QoS). In a QoS-enabled network, you can prioritize network traffic flow, allocate
network bandwidth and resources to different applications and users, enforce security to the
applications and the users entering your network, and set network behavior according to the
business needs. Using QoS approach, an application would request a certain level of service
prior to using the network. If bandwidth is expensive in your region, QoS style approach may
make more sense than just simply adding more bandwidth. It is assumed that there is
insufficient capacity for all users to complete what they want at the same time.
3.5.1 Priority & Bandwidth management
ZyWALL 1050/ZyWALL USG 300 supports both prioritizing and bandwidth
management for outgoing traffic. IT administrator can define bandwidth management policies
to ensure quality of running services in their network environment. ZyWALL 1050/ZyWALL
USG 300 supports bandwidth management policy based on the type of service, origin of the
traffic, user/group to ensure optimized bandwidth utilization. Bandwidth management and
prioritization can be done with policy route in ZyWALL 1050/ZyWALL USG 300.
