IEEE 802.3 (CSMA/CD)

• Ethernet - most popular implementation
• Uses Binary Exponential Backoff for collision resolution

  Fails after 16 tries.

ADVANTAGES	DISADVANTAGES
Widely used	Analog component in DTE
Plug and Play	Minimum frame size
Simple Algorithm	Non-deterministic
Passive Cable	No fairness guarantees
No delay at low load	Low efficiency at high load
