IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
The USB Implementers Forum (USB-IF) defines at least three non-proprietary USB communications device class (USB CDC) protocols with comparable "virtual Ethernet" functionality; one of them (CDC-ECM) predates RNDIS and is widely used for interoperability with non-Microsoft operating systems, but does not work with Windows.
The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active.
An optical multiplexer is used to split transmit and receive signals into different wavelengths (1530 and 1310 nm) allowing them to share the same fiber. Supports up to 10 km, full-duplex only. [13] 100BASE-LX10: 802.3ah-2004 (58) ST, SC, LC: 100 Mbit/s Ethernet up to 10 km over a pair of single-mode fibers, using 1310 wavelength, full-duplex ...
An Ethernet adapter card for the IBM PC was released in 1982, and, by 1985, 3Com had sold 100,000. [16] In the 1980s, IBM's own PC Network product competed with Ethernet for the PC, and through the 1980s, LAN hardware, in general, was not common on PCs. However, in the mid to late 1980s, PC networking did become popular in offices and schools ...
In normal half-duplex operations late collisions do not occur. However, in a duplex mismatch the collisions seen on the half-duplex side of the link are often late collisions. The full-duplex side usually will register frame check sequence errors, or runt frames. [7] [8] Viewing these standard Ethernet statistics can help diagnose the problem.
Wireshark screenshot of an Ethernet pause frame. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x ...
It was defined by the IEEE 802.3 working group as part of the IEEE 802.3ae-2002 amendment which introduced 10 Gbit/s Ethernet. At the time 64b/66b was deployed, it allowed 10 Gb Ethernet to be transmitted with the same lasers used by SONET OC-192 , rather than requiring the 12.5 Gbit/s lasers that were not expected [ when? ] to be available for ...
