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.

WebNeither user 1 nor user 2 knows that they are not on the same ring–the FDDI frame is forwarded transparently. Bridge b 1 must carry out two functions: address conversion … WebJun 14, 2005 · The frame format used by SDH is the Synchronous Transport Module (STM), with STM-1 as the base-level signal at 155.52Mbps. An STM-1 frame can be carried in an OC-3 signal. Both SONET and SDH have a hierarchy of signaling speeds. Multiple lower-level signals can be multiplexed to form higher-level signals. For example, three … http://www.comlab.hut.fi/opetus/423/lect2004/02_supplem_fddi.mht hep-ph dataset
