Fast Ethernet, or 100BaseT, is very similar to standard Ethernet It uses the same contention-based protocol and is usually run over Category 5 UTP cabling Interconnections are made using hubs, switches, and repeaters, just like 10BaseT The most obvious difference is that 100BaseT transmits data at 10 times the speed of 10BaseT The required amount of time for a workstation to detect no carrier on the wire before transmitting is reduced by a factor of 10, from 96 to 096 microseconds 100BaseT also uses a different coding scheme to represent bits on the network, making this protocol incompatible with 10BaseT Fast Ethernet (100BaseTX) typically runs over Category 5 UTP wiring, but it is possible to run it over Category 3 cabling using four pairs of wires This is called 100BaseT4 Three pairs are used for transmission of data, and one is dedicated to handle collision detection 100BaseFX is Fast Ethernet for Fiber Optic Cabling Using fiber-optic allows for greatly increased transmission distances Often, 100 Mbps switches or hubs are connected vertically from floor to floor in a building using 100BaseFX

Token Ring is a LAN standard that avoids the Ethernet topology's contention of shared media Instead, Token Ring uses a token-passing protocol to regulate data flow All devices (called ring stations) are logically configured in a ring (the physical topology is still a star), and a frame called the token is passed around the ring Only the device with the token may place data on the shared media This token-passing protocol eliminates collisions and increases the utilization of the network Token Ring runs at either 4 Mbps or 16 Mbps A basic Token Ring network consists of ring stations connected into a concentrator using Category 5 UTP or STP cabling located centrally in a wiring closet Larger rings can be built by connecting multiple Token Ring hubs using special ports called Ring In (RI) and Ring Out (RO), or by using bridges or routers to connect multiple token rings TOKEN RING FRAME TYPES Frames are the fundamental unit of transmission when referring to the lower two layers of the OSI model Three important types of frames are transmitted on a token ring: tokens, MAC frames, and LLC frames Tokens are used to control the transmission of data onto the ring There is only one token on a ring at a time Ring stations with something to say must claim the free token in order to transmit

This means only one station can transmit at any one time, eliminating collisions Media Access Control (MAC) frames are used by the ring stations to communicate with other ring stations These frames are used to control the operation of the ring and to report errors Token Ring has a very robust set of built-in controls to ensure proper operation Logical Link Control (LLC) frames are the frames with user data These frames use higher-level protocols such as TCP/IP, IPX/SPX, and others to transmit user data SPECIAL RING STATIONS The first ring station on a Token Ring is called the Active Monitor All subsequent ring stations become Standby Monitors The Active Monitor ensures the ring is operating properly It provides master clocking to the ring, removes any frames not claimed by other stations on the ring, compensates for frequency jitter, and ensures there is always only one token on the ring In the event that the Active Monitor doesn't detect a token or a frame on the ring within 10 milliseconds (ms), it will create a new token Before it sends the new token onto the ring, the Active Monitor transmits a Ring Purge frame The Ring Purge frame serves to reset the timers on all the ring stations Once Active Monitor receives the returned Ring Purge frame, it transmits a new token onto the ring If the Ring Purge frame isn't back within 4 ms, Active Monitor transmits another Ring Purge This can continue for up to 1 second, at which time a new Active Monitor is elected BEACONIING Token Ring also has a troubleshooting method called beaconing to identify and attempt to correct hardware errors This can be a fairly complex process, but basically, when a ring station sees a loss of signal on the ring, it sends a Beacon Frame containing the ring station's own address and the address of its Nearest Addressable Upstream Neighbor (NAUN) If the Beacon Frame travels all around the ring and reaches the NAUN, that NAUN station will pull off the ring and try to re-insert The idea is that if the Beacon Frame gets all the way to the NAUN, the problem must reside in the NUAN The re-insertion process includes a self-test that should cause the faulty station to remain off the ring It doesn't always work, though
