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 .
In the IEEE 802.11 wireless LAN protocols (such as Wi-Fi), a MAC frame is constructed of common fields (which are present in all types of frames) and specific fields (present in certain cases, depending on the type and subtype specified in the first octet of the frame). Generic 802.11 Frame
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).
Multiple Access with Collision Avoidance for Wireless (MACAW) [1] is a slotted medium access control (MAC) protocol widely used in ad hoc networks. [2] Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2] The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol.
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.
This time period is called a beacon period (BP). At the beginning of each BP, there is a beacon generation window consisting of w + 1 {\displaystyle w+1} slots each of length aSlotTime . Each station calculates a random delay uniformly distributed in [ 0 , w ] {\displaystyle [0,w]} and is scheduled to transmit a beacon when the delay timer expires.
This requires a media access control (MAC) protocol, i.e. a principle for the nodes to take turns on the channel and to avoid collisions. Common examples are CSMA/CD , used in Ethernet bus networks and hub networks, and CSMA/CA , used in wireless networks such as IEEE 802.11 .
NCR WaveLAN – an early proprietary wireless network protocol HomePNA The ITU-T G.hn standard, which provides a way to create a high-speed (up to 1 Gigabit/s) local area network using existing home wiring ( power lines , phone lines and coaxial cables ), uses CSMA/CA as a channel access method for flows that do not require guaranteed quality ...
