Policy-based Management Overview
Policy-based management provides a way to allocate network resources; primarily network bandwidth, Quality of
Service (QoS), security, and accounting according to defined business policies. These policies can be either static or
dynamic. In a static policy the traffic flow is predefined by exact rules. For dynamic policies, the flows are created
dynamically by external signaling. The dynamic policies validate the flows and apply the necessary policy actions
required for each flow.

required for each flow.
In flow-based traffic policies, policy modules interact with the system through a set of well defined entry points, provide
access to a stream of system events and permit the defined policies to implement access control decisions, provide QoS
enforcement and accounting decisions, etc.
access to a stream of system events and permit the defined policies to implement access control decisions, provide QoS
enforcement and accounting decisions, etc.
A policy is defined as
policy: condition = > action
condition: specifies the flow-parameters such as source-address, destination-address, source-port, destination-
port, protocol, etc. for ingress and/or egress packets.
action: specifies a set of treatments for a flow/packet when condition matches. These actions are typically based
on flow classification and QoS processing for individual flows and DSCP marking.
