Systems and methods for equal opportunity bandwidth regulation are described. In one aspect, data is received from a transmitting entity of one or more transmitting entities. Responsive to receiving the data, the data is transmitted across a bus to a target entity. This transmission is accomplished by dynamically regulating data transmission bandwidth on the bus such that each data transmitting entity of the transmitting entities has a substantially equal opportunity to have bus bandwidth allocated to tranmit data associated with the data transmitting entity.
