Overview of HQoS

Overview of HQoS

HQoS implements hierarchical scheduling based on queues and differentiates services and users.

The traditional QoS technology schedules packets based on interfaces. An interface, however, can identify only priorities of different services, but cannot identify services of different users. Packets of the same priority are placed into the same queue on an interface and compete for the same queue resource. Therefore, the traditional QoS technology is unable to provide differentiated service based on the type of traffic and the identity of a user.

As the number of users increases continuously and services develop, users and carriers require differentiated services to have better QoS. HQoS implements hierarchical scheduling based on queues and differentiates services and users.
