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-byte Ethernet can run without fragmentation. The "PPP-Max-Payload" tag can still accommodate much larger, non-baby jumbo frames.
802.11 frame types. 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). The very first two octets transmitted by a station are ...
It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [ 1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload.
e. In classical physics and special relativity, an inertial frame of reference (also called inertial space, or Galilean reference frame) is a stationary or uniformly moving frame of reference. In this viewpoint, objects rest until acted upon by external forces, and the laws of nature can be observed without the need for acceleration correction.
A sequence of video frames, consisting of two keyframes (I), one forward-predicted frame (P) and one bi-directionally predicted frame (B). Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame ( Intra-coded picture) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture ...
A beacon frame is a type of management frame in IEEE 802.11 WLANs. It contains information about the network. Beacon frames are transmitted periodically; they serve to announce the presence of a wireless LAN and to provide a timing signal to synchronise communications with the devices using the network (the members of a service set ). In an ...
