H3C Technologies H3C SR8800 - Manual (Page 3)

Preface
The H3C SR8800 documentation set includes 13 configuration guides, which describe the software
features for the H3C SR8800 10G Core Routers and guide you through the software configuration
procedures. These configuration guides also provide configuration examples to help you apply software
features to different network scenarios.
The ACL and QoS Configuration Guide describes ACL and QoS fundamentals and configurations. It
describes how to use ACLs or other match criteria to classify traffic into multiple classes and implement
per-class traffic control. ACL and QoS help you allocate limited network resources reasonably and
improve the network utilization. You can use HQoS to control internal resources of a router based on
policies. HQoS guarantees QoS for advanced users and saves the overall networking costs.
