Shaping Traffic
Managing the flow of data across your network helps to ensure network efficiency by maximizing
bandwidth and avoiding congestion. Manage network traffic using traffic policing and traffic shaping.
Using these tools, you can configure your system to effectively manage issues before an overload on the
network. Traffic policing uses rate-limiting to regulate traffic and traffic shaping regulates traffic by
shaping it to a specified rate. Deploying policing and shaping throughout your network helps to ensure
that a packet, or data source, conforms to the QoS policies contracted for it.
The Cisco 10000 series router supports traffic policing and shaping. This chapter describes traffic
