RIF Routing Information Field . Field in the IEEE 802.5 header that is used by a source-route bridge to determine through which Token Ring network segments a packet must transit. A RIF is made up of ring and bridge numbers as well as other information. RII Routing Information Identifier . Bit used by SRT bridges to distinguish between frames that should be transparently bridged and frames that should be passed to the SRB module for handling. ring Connection of two or more stations in a logically circular topology.
Information is passed sequentially between active stations.
Token Ring, FDDI, and CDDI are based on this topology. Time required for a signal to propagate once around a ring in a Token Ring or IEEE 802.5 network. See also active monitor and standby monitor . Each station on the network connects to the network at a repeater. While logically a ring, ring topologies are most often organized in a closed-loop star.
