Abstract

See full text

A method and implementation are disclosed of partitioning data traffic over a network. The invention includes providing a network having a plurality of priority queues for forwarding data packets where a predetermined number of credits are assigned to each priority queue. Data packets are passed to respective ones of a plurality of priority queues. If at least one of the predetermined number of credits is available, the credit is associated with a respective data packet and the packet is forwarded to a flow queue associated with the respective priority queue. If at least one of the predetermined number of credits is not available, the data packet waits until a credit is returned. When a packet is transmitted, its respectively associated credit is returned to the queue in which it originated for associating with another respective waiting data packet.
