    The header features destination and source MAC addresses (each six octets in length), the EtherType field and, optionally, an IEEE 802.1Q tag or IEEE 802.1ad tag. The EtherType field is two octets long and it can be used for two different purposes.

    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 ...

    The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.

    The MAC header on any of the NNI links would show an outer source address of 00:00:00:70:00, an outer destination address of 00:00:00:50:00 and a BVID of either 101 or 102 depending on which has been chosen for this set of non-participating ports/vids.

    IEEE 802.15.4 protocol stack. Devices are designed to interact with each other over a conceptually simple wireless network.The definition of the network layers is based on the OSI model; although only the lower layers are defined in the standard, interaction with upper layers is intended, possibly using an IEEE 802.2 logical link control sublayer accessing the MAC through a convergence sublayer.

    1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector. A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1] Male pin headers are cost-effective due to their simplicity.

  8. Waveguide flange - Wikipedia

    en.wikipedia.org/wiki/Waveguide_flange

    The gap between the flange faces has been exaggerated by a factor of four to make it clearly visible. The choke flange can also be mated with a plain cover flange and still form a pressure seal. A choke connection is formed by mating one choke flange and one cover (or gasket/cover) flange. The central region of the choke flange face is very ...

    This is efficient because Ethernet headers are much shorter than 802.11 headers. [ 1 ] An aggregate MSDU ( A-MSDU ) contains only MSDUs whose destination address (DA) and sender address (SA) parameter values map to the same receiver address (RA) and transmitter address (TA) values, i.e., all the MSDUs are intended to be received by a single ...
