Abstract
The transfer controller with hub and ports uses a write allocation counter and algorithm to control data reads from a source port. The write allocation count is the amount of data that can be consumed immediately by the write reservation station of a slow destination port and the channel data router buffers. This is used to throttle fast source port read operations to whole read bursts until space to adsorb the read data is available. This ensures that the source port response queue is not blocked with data that cannot be consumed by the channel data router and the slow destination port. This condition would otherwise block a fast source port from providing data to the other destination ports.
