Adjustable connection admission control method and device for packet-based switch

摘要

An adjustable connection admission control method and device (22)for packet based switches assigns equivalent bandwidths to variable speed connections. The equivalent bandwidths (18) of the variable speed connections are increased or reduced by a scaling factor (20) to achieve an assigned bandwidth. The method and device determines whether to accept or refuse new variable speed connections based on whether the sum of equivalent bandwidths for existing variable speed connections and new variable speed connections exceeds the bandwidth available to variable speed connections. The connection admission control method and device also determines whether to accept or refuse new constant speed and new unspecified connections.
