Method and system for providing load-sensitive bandwidth allocation
First Claim
1. A method for managing bandwidth in a data network, the method comprising:
- allocating capacity on a communication channel for a terminal to transmit data over the communication channel; and
in anticipation of the terminal having to transmit additional data, further allocating additional capacity on the communication channel for the terminal, wherein the anticipatory allocation is determined according to loading of the data network.

Abstract
An approach is provided for managing bandwidth in a data network. Capacity is allocated on a communication channel, which can be utilized for transporting data traffic or support network administrative functions (e.g., ranging), for a terminal to transmit data over the communication channel. In anticipation of the terminal having to transmit additional data, additional capacity is allocated on the communication channel for the terminal prior to receiving a request for bandwidth by the terminal. The anticipatory allocation is determined according to loading of the data network. This approach as particular applicability to shared capacity systems, such as a satellite communication system.
