Regulating and Shaping Subscriber Traffic
With the increasing demand for Internet services, service providers must ensure that network resources
are available to all subscribers as contracted in their Service License Agreements (SLAs). Service
providers must determine which traffic enters the network, how to distribute shared resources, and how
to manage the volume and rate of traffic entering the network. Without such management, providing
basic services to subscribers can become difficult.
Rate limiting and shaping subscriber traffic are two tools critical to ensuring successful network
operation. Using these tools to regulate subscriber traffic, service providers can protect shared network
resources and ensure that subscribers use only their fair share of bandwidth.
This chapter describes the following subscriber-based traffic regulating and shaping features:
