Abstract
The present invention relates to the field of data communication networks. More specifically, it pertains to devices and methods for the management of bandwidth on links between routing nodes in data networks. The system is particularly useful for reducing congestion caused by high volume traffic streams. The invention provides a novel router that separates traffic on the basis of data type into separate queues buffers. The various queue buffers are associated with virtual output ports on a common physical link. A scheduler regulates the data release from the queue buffers into the physical link to control the bandwidth portion that is made available to each type of data.
