COMPUTING NETWORK MANAGEMENT - Essay Example The company has multiple sites that need to be interconnected and all the sites are located in neighbouring areas. The proposed LAN for Transcom Tax Analysis Ltd is the Token Ring LAN. The ring shaped network basically uses baseband transmission with the token access method. The bus usually consists of screened four core cable and the equipment is connected via MAUs. Up to eight PCs can be connected to one MAU (Atkins and Norris, 1995). A total of 260 MAUs can be included in one ring. Several rings can be connected together by means of a bridge. The topology can be a combination of start and rings (Atkins and Norris, 1995). All the MAUs lie on the ring while the computers are connected in a star to the MAU. A special bypass device in the MAU senses which of the computers are not in use and cuts them out of the ring (Leinwand, 1995). Other connections in the MAU are included in the ring. The network follows the Institute of Electrical and Electronic Engineers (IEEE) standard 802.2 for link protocol and 802.5 for connection to the medium (Atkins and Norris, 1995). The normal transmission rate is 4 Mbits/s, but speed of up to 16 Mbits/s is possible. By analysing the company needs and requirements, it is clear that the company is in need of a Token Ring LAN that is designed in association with one or multiple MAUs. One MAU is enough for smaller locations but for larger locations, more than one MAU should be employed (Pountain, 2001). As the company’s working procedures are well spread, they are in need of more than one MAUs, which will be connected together developing one MAU as the central authority. The Token Ring Topology is considered more reliable and secure due to which, the company’s security issue will be resolved. Moreover, the Token Ring Topology is the best choice for those networking environments that have heavy workload. UTP cable is more sensitive to EMI
