Gigabit Ethernet Buffered Repeater Full Duplex Implementation
The buffered repeater is a cost-effective way to maximize Gigabit Ethernet throughput.
Buffered distributor/repeater uses full duplex links (a natural consequence of using fiber-optic physical layer).
Buffered repeater transmits each packet to all other connected nodes and can simultaneously receive on multiple ports by storing frames in its local memory. To avoid memory overflow there is flow control messaging to the transmitting node to stop sending while the repeater empties its buffers.
