What are the advantages 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.
How is Token Ring different from FDDI?
State the difference between token ring and FDDI? Token ring uses single ring, FDDI uses additional ring to achieve better results and less chance of failure. FDDI uses a timed token protocol where Token Ring uses priority/reservation token access, leading to difference in frame format and how station traffic handled.
What are the advantages and disadvantages of Token Ring?
Benefits & Drawbacks of Token Ring Topology
- Packet collision is reduced and the flow of data is managed in only one direction i.e. in the circular.
- High-speed data transfer between workstations.
- Easier maintenance of the network.
- Server is not needed to control the connectivity between every workstation.
What is an advantage of a Token Ring transmission method?
Usually token ring topologies have a transmission speed of 4 or 16 Mbit/s, but in theory speeds of 100 Mbit/s or 1 Gbit/s are also possible….Pros and cons of token rings.
| Pros | Cons |
|---|---|
| No collisions | Old technology |
| Internal error detection and correction | Slow |
| Stations can be easily added and removed | Expensive hardware |
What are the features and limitation of 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.
What is token in Token Ring?
A token-ring network is a local area network (LAN) topology that sends data in one direction throughout a specified number of locations by using a token. The token is the symbol of authority for control of the transmission line.
How FDDI offers higher reliability than token ring protocol?
Q-2. How FDDI offers higher reliability than token ring protocol? Ans: Token ring protocol is applicable in a single ring. Disadvantage of this protocol is that, if one segment of wires fails or a node fails, the protocol cannot work.
How collision is avoided in Token Ring?
Token Ring eliminates collision by the use of a single-use token and early token release to alleviate the down time. Ethernet alleviates collision by carrier sense multiple access and by the use of an intelligent switch; primitive Ethernet devices like hubs can precipitate collisions due to repeating traffic blindly.
What are some drawbacks of implementing a ring token passing?
Disadvantages of Ring topology :
- Due to the Uni-directional Ring, a data packet (token) must have to pass through all the nodes.
- If one workstation shuts down, it affects whole network or if a node goes down entire network goes down.
- It is slower in performance as compared to the bus topology.
- It is Expensive.
What does FDDI mean?
Fiber Distributed Data Interface
FDDI (Fiber Distributed Data Interface) is a network standard that uses fiber optic connections in a local area network (LAN) that can extend in range up to 200 kilometers (124 miles). The FDDI protocol is based on the token ring protocol. A FDDI LAN can support thousands of users.
How FDDI ring can be used as a backbone to connect LANs and computers?
FDDI (Fiber Distributed Data Interface) is a network standard that uses fiber optic connections in a local area network (LAN) that can extend in range up to 200 kilometers (124 miles). The FDDI protocol is based on the token ring protocol. A FDDI LAN can support thousands of users.
Is Token Ring reliable?
Networking technologies such as Ethernet, Token Ring and FDDI provide a data link layer function; that is, they allow a reliable connection between one node and another on the same network.
What is the difference between token ring and FDDI ring?
Like token ring, FDDI also has error-detection and correction capabilities. In a normally operating Fiber Distributed Data Interface (FDDI) ring, the token passes by each network device fast. If the token is not seen within the maximum amount of time that it takes to circulate the largest ring, it indicates a network problem.
What is the difference between FDDI and ring topology?
One is primary ring and the second ring is used to replace the primary ring in the case of a network failure. Fiber Distributed Data Interface (FDDI) uses fiber-optic cable and is wired in a ring topology and Fiber Distributed Data Interface (FDDI) uses token passing as its media-access method and can operate at high speeds.
Why is FDDI so expensive to set up?
Fiber Distributed Data Interface (FDDI) is an expensive technology to set up because the network devices require a special network card and also fiber-optic cabling is required, which is expensive than twisted-pair cable. Because most Fiber Distributed Data Interface (FDDI) installations use a redundant second ring, more cabling is required.
How many stations can be on a dual-ring FDDI network?
There can be up to 500 stations on a dual-ring FDDI network. The maximum circumference for an FDDI ring is 100 kilometers (or 200 kilometers for both rings combined), and there must be a repeater every 2 kilometers or less. Bridges or routers are used to connect the FDDI backbone network to Ethernet or token ring departmental LANs.
