Bandwidth Management of P2P Traffic
The Cisco SCE uses unique signatures to identify the networking flows of P2P, IM, and other
applications. While defining packages to subscribers, you can create rules for different types of
applications such as P2P, and IM and if required, associate these rules to separate Bandwidth Controls
(BWCs). With BWC enforcement, you can limit the networking flows for all types of applications. There
are three types of rules in the Cisco SCE which can be used for bandwidth enforcement at different
levels.
•
P2P based BWC
If the Cisco SCE is configured to enforce BWC based on peer-to-peer traffic, it detects the application
based on its signature. Cisco SCE then includes the amount of network flows of P2P traffic and
calculates the bandwidth accordingly. The consumed bandwidth is the sum of P2P data and the control
traffic. Bandwidth limitation takes place as per the enforcement configured in the BWC.
•
Default Service BWC
When an application is configured with discrete BWC, the Cisco SCE does not relate the amount of
networking flows of the application when calculating the bandwidth consumed by it. The amount of
networking flows consumed by the application is accounted with the Default Service. If there is any rate
limit associated with Default Service BWC, this amount is accounted with Default Service BWC.
