1. A method for shaping traffic of a communication system, the method comprising:
- comparing capacity usage by a network element of the communication with a plurality of thresholds indicating loading of the communication system; and
in response to the comparison, regulating traffic to the network element according to one of a plurality of transmission states corresponding to the plurality of thresholds and a committed information rate (CIR) designated for the network element.

Abstract
An approach is provided for supporting a fair access policy to exchange traffic in a radio communication system. A committed information rate (CIR) level is assigned to a terminal according to one of a plurality of throttling states that specify respective different throughput levels according to loading of the communication system. The traffic is forwarded to the terminal based on the current throttling state of the terminal, wherein the traffic throughput is limited to the CIR level of the terminal. This approach as particular applicability to shared capacity systems, such as a satellite communication system.

9. A system for forwarding traffic in a communication network based on class of service levels, the system comprising:
-
logic configured to compare capacity usage by a terminal with a plurality of thresholds indicating loading of the communication network, wherein the logic is further configured to regulate the traffic to the terminal according to one of a plurality of transmission states corresponding to the plurality of thresholds and one of the class of service levels; and
a queue organized according to the class of service levels and configured to store a frame destined to the terminal according to the one class of service level if the capacity usage exceeds a committed information rate (CIR) associated with the terminal. - View Dependent Claims (10, 11, 12, 13, 14)
