Why is Ethernet Successful?
Ethernet is inexpensive and easy to administer. It is easy to increase or decrease the number of nodes in the network.
In practice Ethernets are divided into subnetted segments which have less than 254 nodes and typically ~5 µs network delay. This is much less than the standard allows (maximum of 1024 nodes and 51.2 µs maximum delay) and helps keep the network data traffic load low.
Because network capacity is wasted by collisions, Ethernet works best under lightly loaded (< 30 % capacity) network traffic conditions.
Ethernet does not provide link-level flow control. End-to-end flow control is provided by the host. This avoids instabilities such as hosts continuously pumping frames into the network.
