Bandwidth management is the process of measuring and controlling the communications (traffic, packets) on a network link, to avoid filling the link to capacity or overfilling the link, which would result in network congestion and poor performance.
Many aspects of the Internet protocol suite prevent communications links from reaching their maximum capacity in practice. Therefore, it is necessary to keep the link utilization below the maximum theoretical capacity of the link, in order to ensure fast responsiveness and eliminate bottleneck queues at the link endpoints, which increase latency.
Traffic shaping is an attempt
to control network traffic in order to optimize or guarantee
performance, low-latency, and/or bandwidth. Traffic shaping deals with
concepts of classification, queue disciplines, enforcing policies,
congestion management, quality of service (QoS), and fairness.
Traffic shaping can improve you latency,service availability and bandwith utilization.
So it can give you :
- Granular control of network services
- More efficient use of limited/shared resources
- Guaranteed quality of service
Defzone products combine bandwidth management with Quality of Service (QoS). Quality of Service refers to resource reservation control mechanisms. Quality of Service can provide different priority to different users or data flows, or guarantee a certain level of performance to a data flow in accordance with requests from the application program or the internet service provider policy.
