Abstract

Each sink port in a cross-bar switch provides for allocating bandwidth among data packets. Packets are assigned priority levels, and the cross-bar switch regulates bandwidth allocation for each priority level. A sink port records traffic volume for packet data of each priority level. The sink port calculates a weighted average bandwidth for each different priority level and determines whether to reject packet data for the priority level. When the packet data collected by a sink port exceeds a threshold, the sink port rejects data packets with priority levels having excessive weighted average bandwidths.
