Note
The number of devices connected in a line, which are named in the scope of validity, influences
the frame delay. When a frame passes through an IE switch, it is delayed by the store-and-
forward function of the device:
• With a 64-byte frame length by about 10 microseconds (at 100 Mbps)
• With a 1500-byte frame length by about 130 microseconds (at 100 Mbps)
This means that the more devices the frame passes through, the higher the frame run time.
