Gigabit Ethernet Flashcards

Q
Carrier Extension
A
- frame length of a transmission being longer than the propagation time at 1Gbps (principle of CSMA/CD)
- now transmission at least 4096 bit-times long (512 bit-times for 10/100, min. frame length of 64 octets)

Q
Frame Bursting
A
- multiple short frames transmitted consecutively,
without CSMA/CD control; avoids the overhead of carrier extension when a single station has a number of small frames ready to send
