The competing MGBASE-T Alliance, stating the same faster Gigabit Ethernet objectives, was founded in December 2014. [15] In contrast to NBASE-T, the MGBASE-T said that their specifications would be open source. [16] IEEE 802.3's "2.5G/5GBASE-T Task Force" started working on the 2.5GBASE-T and 5GBASE-T standards in March 2015. [17]
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).
Initially, Gigabit Ethernet was deployed in high-capacity backbone network links (for instance, on a high-capacity campus network). In 2000 and 2001, Apple's Power Mac G4 and PowerBook G4 respectively were the first mass-produced personal computers to feature the 1000BASE-T connection. [2] It quickly became a built-in feature in many other ...
The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.
The media-independent interface (MII) was originally defined as a standard interface to connect a Fast Ethernet (i.e., 100 Mbit/s) medium access control (MAC) block to a PHY chip. The MII is standardized by IEEE 802.3u and connects different types of PHYs to MACs.
The increased overhead of extra MPLS and Ethernet headers means that the support for frames up to 1600 bytes is required in Carrier Ethernet networks. [ 19 ] Jumbo frames for PPPoE is defined in RFC 4638, with the purpose of removing the old 1492-byte limit (originally defined because PPP needs 8 more bytes of overhead), so that normal 1500 ...
A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...
Therefore, the NDIS acts as the interface between the media access control (MAC) sublayer, which is the lower sublayer of the data link layer, and the network layer (layer 3). The NDIS is a library of functions often referred to as a " wrapper " that hides the underlying complexity of the NIC hardware and serves as a standard interface for ...
