Admission control for packet connections

A computer readable medium that stores computer executable program instructions, execution of which results in operations that comprise:

• time stamping packets when the packets enter a queue;
• when a packet is taken from the queue updating an average queuing delay estimate;
• and
• comparing a resulting average queuing delay estimate to an admission threshold for making an admission decision.

A method, comprising:

• in response to at least one slot being granted to a certain connection, updating an average throughput of the connection;
• dividing the averaged connection throughput by a minimum bandwidth requirement of the connection;
• calculating an average throughput over all (N) normalized throughputs;
• and
• comparing the result to a throughput threshold.
