ABSTRACT:
A data rate controller controls a rate that data is transferred over a backplane in a network processing device. A bandwidth allocator allocates bandwidth to an input port for transmitting data over the backplane to an output port. A bandwidth limiter identifies a maximum allowable bandwidth the input port is allocated on the backplane. A bandwidth tracker identifies an amount of bandwidth currently allocated to the input port for transmitting data over the backplane to the output port. When the current allocated bandwidth is used up, the data rate controller prevents that input port from connecting to output ports through the backplane until more bandwidth is allocated.
