The 802.1AE standard specifies the implementation of a MAC Security Entities (SecY) that can be thought of as part of the stations attached to the same LAN, providing secure MAC service to the client. The standard defines MACsec frame format, which is similar to the Ethernet frame, but includes additional fields:
In IEEE 802 networks such as Ethernet or IEEE 802.11, each frame includes a destination MAC address. In non-promiscuous mode, when a NIC receives a frame, it drops it unless the frame is addressed to that NIC's MAC address or is a broadcast or multicast addressed frame. In promiscuous mode, however, the NIC allows all frames through, thus ...
Ethernet devices must allow a minimum idle period between transmission of Ethernet packets. [1] A brief recovery time between packets allows devices to prepare for reception of the next packet. While some physical layer variants literally transmit nothing during the idle period, most modern ones continue to transmit an idle pattern signal.
IEEE 802.1aq is an amendment to the IEEE 802.1Q networking standard which adds support for Shortest Path Bridging (SPB).This technology is intended to simplify the creation and configuration of Ethernet networks while enabling multipath routing.
The original 2.94 Mbit/s Ethernet implementation had eight-bit addresses and other differences in frame format. [9] 10BASE5: 802.3-1985 (8) AUI, N, vampire tap: 500 m RG-8/U Original standard uses a single coaxial cable in which a connection is made by tapping into the single cable, drilling in to make contact with the core and the screen.
The work also required a short amendment extending the frame size of the Ethernet standard by four bytes which was published as IEEE 802.3ac in 1998. The QoS technique developed by the working group, also known as class of service (CoS), is a 3- bit field called the Priority Code Point (PCP) within an Ethernet frame header when using VLAN ...

This is achieved by sending the network traffic to multiple destinations on an Ethernet network. [2] As a concept related to computer networking, it includes three types of Ethernet modes: broadcast, unicast and multicast Ethernet. BUM traffic refers to that kind of network traffic that will be forwarded to multiple destinations or that cannot ...
