Common topology of the network architecture
Ring Network
In industrial networks, feature redundancy, network cable connection and easy expansion capabilities, the benefits are important, Ring network is capable of all the above items.
Advantages :
1. exponentially reduces the need for cabling.
2. redundancy capabilities
3. Change a switch or expand the network, without the need for overall system glitch
4. Ease of connecting devices to the network via the nearest Node
5. regular network
6. Use the Long Haul
Disadvantages:
1. In the event of a network outage fail simultaneously two switches (rarely occurs)
2. If you require high bandwidth of applications in the Ring
Network Star
Advantages
• Simplicity network service. STAR topology includes a number of connection points is a central point. The above changes in the structure to facilitate networking features and services.
• Every time you connect a device. The network connections are inherently prone forms. STAR topology forms a circuit, causing its exit from the network and the service line and the line is debugging. The operation does not affect the operation of other computers on the network.
• Central control and troubleshooting. Due to the fact that central point is connected directly to any station on the network, malfunction in the network will be easy to recognize and harness.
• Easy access methods. Each connector includes a central point and a node on the network side. In this case access to the transmission medium to send and receive data will be simple algorithm.
Disadvantages
• A length of cable. Because each node is connected directly to a central point, a lot of cable is used. Given that the cost of the entire network cables, low-density channel for cable laying and installation issues and their support costs will increase significantly.
• Development of the problem. Adding a new node to the network requires a connection from a central point to the new node. While the cable provision is intended to develop, but in some cases, such as when required length of cable, or connect a set of nodes unpredictable primary, network development with problem will face.
• dependence on the central point. If the center point) hub (the network fails, the entire network will be useless.
