IPv6 multicast: [41] The low 32 bits an Ethernet address for IPv6 multicast traffic are the low 32 bits of the multicast IPv6 address used. [ 40 ] : §2.3.1 For example, IPv6 multicast traffic using the address ff02::d uses the MAC address 33-33-00-00-00-0D , and traffic to ff05::1:3 goes to the MAC address 33-33-00-01-00-03 .
IEEE 802.11s is a wireless local area network (WLAN) standard and an IEEE 802.11 amendment for mesh networking, defining how wireless devices can interconnect to create a wireless LAN mesh network, which may be used for relatively fixed (not mobile) topologies and wireless ad hoc networks.
The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision and therefore potentially high accuracy. In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control systems. [ 1 ]
The time is measured from the end of the frame check sequence of one frame to the start of the preamble for the next. [ 2 ] : 5 During data reception, some interpacket gaps may be smaller due to variable network delays, clock tolerances (all speeds), and the presence of repeaters (10 Mbit/s only).

IEEE 802.11be, dubbed Extremely High Throughput (EHT), is a wireless networking standard in the IEEE 802.11 set of protocols [9] [10] which is designated Wi-Fi 7 by the Wi-Fi Alliance. [ 11 ] [ 12 ] [ 13 ] It has built upon 802.11ax , focusing on WLAN indoor and outdoor operation with stationary and pedestrian speeds in the 2.4, 5, and 6 GHz ...
The 802.11w amendment is implemented in Linux and BSDs as part of the 80211mac driver code base, which is used by several wireless driver interfaces; i.e., ath9k. The feature is easily enabled in most kernels and Linux OS's using these combinations. OpenWrt in particular provides an easy toggle as part of the base distribution.
The use of TXOPs reduces the problem of low rate stations gaining an inordinate amount of channel time in the legacy 802.11 DCF MAC. A TXOP time interval of 0 means it is limited to a single MAC service data unit (MSDU) or MAC management protocol data unit (MMPDU). The levels of priority in EDCA are called access categories (ACs).
