FDDI in Computer Networks
Fiber Distributed Data Interface is referred to as FDDI. It is a collection of ANSI and ISO standards for data transfer over fiber-optic lines in Local Area Networks (LANs) with a maximum length of 200 kilometers (124 miles).
The token ring protocol serves as the foundation for the FDDI convention. An FDDI neighborhood region is not only geographically large, but it also has the capacity to serve thousands of clients. Wide Area Networks (WANs) typically use FDDI as their spine.
It is appropriate for backbone networks, particularly in campus or metropolitan area networks, due to its reputation for dependability and long-distance coverage.
Features of the FDDI
- It is used for long-distance equipment association with the ring.
- 100 Mbps of information throughput is provided by FDDI.
- Two interfaces are incorporated into FDDI.
- A LAN with Station Management could be FDDI.
- The FDDI distinguishes between two types of traffic: synchronous and asynchronous.
- Permits all stations to have achieved a break-even point in terms of the total amount of time spent transmitting data.
Advantages of FDDI
- Because it is difficult for someone to spy on the fiber-optic link, it provides high security.
- Compared to other types of cables, fiber optic cable is less likely to break. Signals are sent by fiber optic cables over longer distances of about 200 kilometers.
- Providing the necessary supplies to the work stations connected to the chain is feasible.
- As a result, some stations are avoided based on the requirement in order to provide the others with faster benefits.
- It provides up to 250 Gbps of transmission capacity. As a result, it can process data at speeds of up to 100 Mbps.
Disadvantages of FDDI
- The cost of FDDI is high. Usually because fiber optic cable, concentrators, and connectors are very expensive.
- FDDI is complicated. Thus, a remarkable amount of skill is needed for establishment and support.
- FDDI is less appropriate for applications that are sensitive to latency since it may have higher delay than some other technologies.
- Compared to other technologies, its range is constrained, despite the fact that it can accommodate a significant number of stations.
- Largely superseded by more affordable and rapid technologies like as gigabit Ethernet.
