What do you know about Token Ring and Token Bus?
Differences between Token Ring and Token Bus
| Token Ring | Token Bus |
|---|---|
| The stations are connected by ring topology, or sometimes star topology. | The underlying topology that connects the stations is either bus or tree topology. |
| It is defined by IEEE 802.5 standard. | It is defined by IEEE 802.4 standard. |
What is the main difference between CSMA and Token Ring access mechanisms?
CSMA/CD and token ring networks operate at different link speeds. The former protocol typically uses a bandwidth capacity of 10 Mbps, whereas the latter protocol often operates at speeds of 16 Mbps. A data stream arriving from a CSMA/CD network can be forwarded onto a token ring network at a higher speed.
What is the major difference between token rings and Ethernet?
The token ring contains the routing information. Ethernet does not contain the routing information. Token rings are quite slow in terms of speed of data transmission, which is probably 16M bit/ sec. Ethernet is many times faster in terms of speed of data transmission, which is probably 100M bit/ sec.
What are the advantages of token ring?
Token Ring technology uses ring topology for data transfers and provides more advanced congestion management than that available in Ethernet. One of the major advantages of the Token Ring (TR) is no collision in the network and, therefore, utilization can reach 100% under heavy load.
What are the pros and cons of Token Ring?
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 two complementary deadlock prevention schemes?
There are two schemes to prevent deadlock called wound-wait and wait-die.
What is the difference between token bus network and Token Ring network?
1. In the token bus network the token is passed along a virtual ring. While in the token ring network the token is passed over a physical ring. 2. The token bus network is simply designed for the large factories. While the token ring network is designed for the offices. 3. The token bus network is defined by the IEEE 802.4 standard.
What topology does Token Ring network use?
Token Ring network uses Star topology. The maximum time to reach the last station in the Token Bus network is not easy to calculate. The maximum time to reach the last station in the Token Ring network can be calculated easily.
How are tokens passed through a coaxial cable network?
The token is passed over the physical ring formed by the stations and the coaxial cable network. The token is passed along the virtual ring of stations connected to a LAN. The stations are connected by ring topology, or sometimes star topology. The underlying topology that connects the stations is either bus or tree topology.
What does it mean to pass the token?
Passing the token means receiving the token from the preceding station and transmitting to the successor station. The data flow is unidirectional in the direction of the token passing. In order that tokens are not circulated infinitely, they are removed from the network once their purpose is completed. This is shown in the following diagram −
