Which protocol is used in FDDI?

token ring protocol
It is a set of ANSI and ISO guidelines for information transmission on fiber-optic lines in Local Area Network (LAN) that can expand in run upto 200 km (124 miles). The FDDI convention is based on the token ring protocol.

What is the purpose of FDDI?

Fiber Distributed Data Interface (FDDI) is a set of ANSI and ISO standards for transmission of data in local area network (LAN) over fiber optic cables. It is applicable in large LANs that can extend up to 200 kilometers in diameter.

Which type of network is FDDI?

Although FDDI logical topology is a ring-based token network, it did not use the IEEE 802.5 Token Ring protocol as its basis; instead, its protocol was derived from the IEEE 802.4 token bus timed token protocol. In addition to covering large geographical areas, FDDI local area networks can support thousands of users.

What is FDDI in ring topology?

Fibre Distributed Data Interface (FDDI) is a networking standard developed in the early 1980s by the American National Standards Institute (ANSI) for operating at speeds up to 100 Mbps. FDDI uses the same token-passing scheme as the IEEE 802.5 Token Ring network to control transmission around the loop.

What is FDDI write advantages and disadvantages of FDDI?

Benefits or advantages of FDDI ➨It offers higher bandwidth (upto 250 Gbps). Hence it can handle data rates upto 100 Mbps. ➨It offers high security as it is difficult to eavesdrop on fiber optic link. ➨Fiber optic cable does not break as easily as other types of cables.

What are the key elements of the protocol?

The key elements of protocol are syntax, semantics and timing.

• Syntax: Syntax refers the structure and format of the information data.
• Semantics: Semantics refers to the meaning of each section of bits.
• Timing: Timing refers to two characteristics: when data should be sent and how fast it should be sent.

What are the main characteristics of the FDDI?

Answers : The Fiber Distributed Data Interface (FDDI) main characteristics are 100 Mbit/s , token passing, dual counter rotating ring network and the fault tolerant features. The main limitation of the FDDI is the limited 100 Mbps bandwidth and the packet delay.

Which topology is used in Ethernet?

Star and Extended Star Topologies The star and extended star are the most popular topologies for Ethernet networks. This type network is easy to setup, relatively inexpensive, and provides more redundancy than other topologies, i.e. bus topology.

What are the disadvantages of FDDI?

Drawbacks or disadvantages of FDDI ➨FDDI is complex. Hence installation and maintenance require great deal of expertize. ➨FDDI is costly. This is because fiber optic cable, adapters and concentrators are very expensive.

What are the features and limitation of FDDI?

What is a standard protocol?

Standard protocols are agreed and accepted by the whole computing industry. Standard protocols are often developed by collaborative effort of experts from different organizations. Examples of standard protocols are IP, TCP, UDP etc. RFC (Request for Comments) is an IETF platform to develop Standard Protocols.

What is fiber optic interface?

A parallel optical interface is a form of fiber optic technology aimed primarily at communications and networking over relatively short distances (less than 300 meters), and at high bandwidths.

What is fiber ring network?

A fiber ring is a network topology in which each node connects to two other nodes, forming a single continuous pathway for data to travel.

What is fiber interface?

FDDI (Fiber Distributed Data Interface) is a set of ANSI and ISO standards for data transmission on fiber optic lines in a local area network (LAN) that can extend in range up to 200 km (124 miles). The FDDI protocol is based on the token ring protocol.
