An FDDI frame is very similar to that defined by the traditional token ring, but there are only eight fields. The Token and frame format for the FDDI shown in …
WebThe hardware address, or MAC address is transmitted and stored in Ethernet network devices in Canonical format i.e. Least significant Bit (LSB) first. You may hear the expression Little-Endian to describe the LSB format in which Ethernet is transmitted. Token Ring and FDDI, on the other hand, transmit the MAC address with the Most Significant … WebThe FDDI frame format is similar to the format of a = Token=20 Ring frame. This is one of the areas in which FDDI = borrows=20 heavily from earlier LAN technologies, such as Token Ring. FDDI frames = can be as=20 large as 4,500 bytes. Figure 8-10 shows the frame format of an FDDI data = frame=20 and token.
WebThe FDDI frame format, depicted in Figure 2.36, differs in very few ways from that for 802.5. Because FDDI uses 4B/5B encoding instead of Manchester, it uses 4B/5B control symbols rather than illegal Manchester symbols in the start- and end-of-frame markers.
