Class of Service and Broadband Subscriber Management Overview
Class of service (CoS) is a mechanism that enables you to divide traffic into classes and offer various levels of throughput and acceptable packet loss when congestion occurs. CoS also provides the option of using differentiated services when best-effort traffic delivery is insufficient. You can also configure the services router to provide hierarchical scheduling for subscribers by dynamically adding or deleting queues when subscribers require services.
By using a dynamic profile, you can provide all subscribers in your network with default CoS parameters when they log in. For example, you can configure an access dynamic profile to specify that all subscribers receive a basic data service. If you use RADIUS variables in the dynamic profile, you can enable the service to be activated for those subscribers at login. You can also use variables to configure a service profile that enables subscribers to activate a service or upgrade to different services through RADIUS change-of-authorization (CoA) messages following initial login.
