4.5 Configuring congestion management
4.5.1 Preparing for configurations
Scenario
When network has congestion, user want to balance delay and delay jitter of various packets,
packets of key services (like video and voice) can be processed preferentially; packets of
secondary services (like E-mail) with identical priority can be fairly processed, different
priority can be processed according to its weight value. You can configure queue schedule in
this situation. Selection of schedule algorithm is depended on service condition and customer
requirements.
