iBG3026 Quality of Service

The iBG3026 supports software-based QoS in the operating system. It also
supports hardware-based QoS which is enforced in the chipset. Each type of
QoS support has its own configuration capability in the CLI.
The following sections describe the software-base features of QoS followed
by a description of hardware-based QoS.
iBG3026 QoS ensures bandwidth guarantees throughout the system by
implementing Random Early Detection(RED) to address congestion and Class
Based Queuing(CBQ) to address traffic policing.
iBG3026's bandwidth management capability allows multiple agencies or
customers to share access bandwidth on a WAN link in a controlled fashion to
effectively and efficiently utilize available bandwidth. Even during times of
congestion, each customer is guaranteed a share of the access bandwidth and
is allowed to borrow unused bandwidth from other customers. This bandwidth
management capability allows service providers to offer their customers
Internet access based on the amount of guaranteed bandwidthcommitted rate
(CR) and the amount of bandwidth-borrowed burst rate(BR).
Similarly, an organization can share its access bandwidth among its different
departments.
