A bandwidth packing rate control technique includes altering bandwidth allocations of existing flows on a link depending on a current utilization of a current bandwidth allocation for a flow. A disclosed example decreases the bandwidth allocation for flows that are utilizing a current bandwidth allocation below a selected target utilization rate. Flows with higher utilization can receive increased bandwidth allocation, which provides increased throughput for such flows. One overall result of a disclosed example is increased utilization and increased throughput using existing bandwidth resources.

Bandwidth packing rate controller for optimizing resource utilization

By approximating a packet network, such as the Internet, by an M/M/1 queuing model, the available bandwidth of the network can determined from the variance of the distribution of the sojourn times of packets transmitted through the network. In order to determine the variance of the distribution of sojourn times, and thus the bandwidth of the packet network that is available for transport of packets from an input to an output, a probe train of N packets with known inter-packet intervals is injected from an input on a sending side of the network. At the receiving side of the network, the packet arrival times are measured and the inter-packet intervals of each pair of received packets in the received train are calculated and compared with the known inter-packet interval times of the corresponding input packets. The variance of the distribution of the sojourn times of the packets through the network can then calculated using these time differences even though the individual sojourn times of the packets through the network cannot be directly measured.

Method and apparatus of estimating available bandwidth on a packet network

A controllerfor a packet radio networkincludes a processorthat, in turn, includes a plurality of processor resourcesA&#x2013;D for processing a plurality of packet classes. Each packet class has a different delay sensitivity associated therewith. The processorallocates to each packet class at least a portion of at least one processor resourceA&#x2013;D, the allocation being based on the delay sensitivities associated with each packet class. Each processor resourceA&#x2013;D may have a processing threshold, and the processormay determine, based upon arriving packets, whether at least one processor resource will exceed its processing threshold, thus defining at least one overloaded processor resourceA. The processormay reallocate at least a portion of at least one processor resource to process packets for the at least one overloaded processor resourceA thereby defining at least one reallocated processor resourceD.
