Glossary
When HUGEN is asserted, the maximum frame size is 32 Kbytes, so
excess deferral in this case is:
32 Kbytes x 8 bits/byte x 2 = 524,288 bits (5242.88
μ
s at 100 Mbit/s or
52.43 ms at 10 Mbit/s)
Fast Ethernet
Compared to the 10-mbit/s specifications, the 100-Mbit/s Fast Ethernet
system results in a factor of ten reduction in the bit time, which is the
amount of time it takes to transmit a bit on the Ethernet channel. The
result is a tenfold increase in the speed of the packets over the media
system. However, the other important aspects of the Ethernet system,
including the frame format, the amount of data a frame may carry, and
the media access control mechanism, are all unchanged.
The Fast Ethernet specifications include mechanisms for auto-negotia-
tion of the media speed. This makes it possible for vendors to provide
dual-speed Ethernet interfaces that can be installed and run at either
10 Mbit/s or 100 Mbit/s automatically.
There are three media varieties that have been specified for transmitting
100-Mbit/s Ethernet signals:
100BASE-TX
100BASE-FX
100BASE-T4
The identifiers include three pieces of information. The first item, “100,”
stands for the media speed of 100 Mbit/s. “BASE” stands for “baseband,”
which is a type of signaling. Baseband signaling simply means that
Ethernet signals are the only signals carried over the media system. The
third part of the identifier provides an indication of the segment type. The
“T4” segment type is a twisted-pair segment that uses four pairs of
telephone-grade twisted-pair wire. The “TX” segment type is a twisted-
pair segment that uses two pairs of wires and is based on the data grade
twisted-pair physical medium standard developed by ANSI. The “FX”
segment type is a fiber optic link segment based on the fiber optic
physical medium standard developed by ANSI and that uses two strands
of fiber cable. The TX and FX medium standards are collectively known
as 100BASE-X.
