Ring Topology

RING TOPOLOGY

Dania in Tech (2015) think it is a network in which each node connects to exactly two other nodes, forming a single continuous pathways for signals through each node. Data travels from node to node, which each node along the way handling every packets. Ring can be unconditional with all traffic either clockwise or anticlockwise around the ring, or bidirectional (as in SONET/SDH). Unidirectional ring network can be disrupted by failure of a single link.  

ADVANTAGES Dania (2015)

·         Data is quickly transferred without a ‘bottle neck’ (very fast, all data traffic is in the same direction).

·         Transmission of data is relatively simple as packets travel in one direction only

·         Adding additional has very little impact on bandwidth

·         Prevents network collision because of media access method

DISADVANTAGES Dania (2015)

·         It is difficult to troubleshoot the ring

·         Total dependence upon the cable

·         Data packets must pass through every computer between sender and recipient therefore this takes it slower

·         If any of the nodes fail then the ring is broken and cannot be transmitted successfully

·         If order for all computers to communicate with each other, all computers must be turned out

·         Because all stations are wired together, to add a station you must shut down the network temporarily.
