Note

The number of ELS switches connected influences the frame propagation time. When a frame passes through the ELS, it is delayed by the Store&Forward func- tion of the switch.

-with a frame length of 64 bytes by approximately 10 ∝s

-with a frame length of 1500 bytes by approximately 130 ∝s

This means that the more ELS switches the frame passes through, the longer the propagation time.
