Abstract
A method dynamically allocates and renegotiates bandwidth to traffic having a variable data rate in a network. A current data rate and current allocated bandwidth is measured. A future data rate for the traffic is predicted. A cost function is then minimized based on the current data rate, the current allocated bandwidth, and the future data rate to determine a future bandwidth to be allocated for the traffic so that a cost of the renegotiation is minimized over time.
Claims7
A method for dynamically allocating and renegotiating bandwidth to traffic having a variable data rate in a network, comprising:
- measuring a current data rate of the traffic in the network;
- measuring a current bandwidth allocation of the traffic in the network;
- predicting a future data rate for the traffic based on the current and previous data rates;
- and
- minimizing a cost function based on the current data rate, the current bandwidth allocation, and the future data rate to determine a future bandwidth allocation for the traffic that minimized a cost of the renegotiation bandwidth over time.
A system for dynamically allocating and renegotiating bandwidth to traffic having a variable data rate in a network, comprising:
- means for measuring a current data rate of the traffic in the network;
- means for measuring a current bandwidth allocation of the traffic in the network;
- a predictor configured to predict a future data rate for the traffic based on the current and previous data rates;
- and
- a renegotiation control unit configured to minimize a cost function based on the current data rate, the current bandwidth allocation, and the future data rate to determine a future bandwidth allocation for the traffic that minimized a cost of the renegotiation bandwidth over time.
