What is Full-duplex Networking?
| Full-Duplex Transmission-An Optional Approach to Higher Network Efficiency |
| What is Full-duplex Networking? Full-duplex operation is an optional MAC (Media Access Control) capability that allows simultaneous two-way transmission over point-to-point links. Full duplex transmission is functionally much simpler than half-duplex transmission because it involves no media contention, no collisions, no need to schedule retransmissions, and no need for extension bits on the end of short frames. The result is not only more time available for transmission, but also an effective doubling of the link bandwidth because each link can now support full-rate, simultaneous, two-way transmission. Transmission can usually begin as soon as frames are ready to send. The only restriction is that there must be a minimum-length interframe gap between successive frames. |
