Ring Topology
updated Nov 9, 2008 7:53 am 33,071 views
A ring topology is a network topology or circuit arrangement in which each network device is attached along the same signal path to two other devices, forming a path in the shape of a ring. Each device in the network that is also referred to as node handles every message that flows through the ring. Each node in the ring has a unique address. Since in a ring topology there is only one pathway between any two nodes, ring networks are generally disrupted by the failure of a single link.
The redundant topologies are used to eliminate network downtime caused by a single point of failure. All networks need redundancy for enhanced reliability. Network reliability is achieved through reliable equipment and network designs that are tolerant to failures and faults. The FDDI networks overcome the disruption in the network by sending data on a clockwise and a counterclockwise ring. In case there is a break in data flow,the data is wrapped back onto the complementary ring before it reaches the end of the cable thereby maintaining a path to every node within the complementary ring.
The most well known example of a ring topology is Token Ring.
[edit]Advantages
An orderly network where every device has access to the token and the opportunity to transmit
Under heavy network load performs better than a start topology.
To manage the connectivity between the computers it doesnt need network server.
[edit]Disadvantages
One malfunctioning workstation can throw away the entire network.
Moves, adds and changes of devices can affect the entire network .
It is slower than an Ethernet network.
