IN QOS DESIGN, THE DESCRIPTION OF THE DESIGN PRINCIPLES OF TRAFFIC SCHEDULING IS INCORRECT ()

Maintain the principle of uniformity in the scheduling strategy of the whole network, and use templated deployment as much as possible to facilitate network management

LPQ/WFQ scheduling strategies can be used to avoid low-priority services not being able to obtain bandwidth resources

The current QoS policy needs to take into account the subsequent expansion of the network

Core services and video-voice services should ensure the absolute priority of forwarding and use PQ scheduling

Unless the business has special requirements, some parameters of the scheduling policy should be defaulted as much as possible

For TCP-based services, the queue must be configured with WRED dropping to avoid TCP global synchronization
