Multiple Logical Token-Rings in a Single High-Speed Ring
The present paper describes a MAC protocol for a high-speed ring with multiple tokens. The purpose of this protocol is to increase the throughput and to improve the delay-throughput characteristic of high-speed token-rings. The main concept of the new MAC protocol is to maintain several logical token-rings in the single physical ring. Each logical ring has its own token, and its operation is cl...
متن کاملOn token protocols for high-speed multiple-ring networks
A token ring protocol which restricts the transmission rights to the station possessing the token is not a good candidate for driving a gigabit network. This is due to the fact that the periods while the token is \in transit" are wasted: they must be subtracted from the eeective throughput achievable by the network. As the network's transmission rate becomes higher, the impact of the token tran...
متن کاملShould You Migrate Your Token Ring Network to Ethernet ?
Token Ring network managers are faced with the difficult decision of staying with Token Ring or migrating to Ethernet. Making matters worse is that analysts, consultants, and vendors do not always agree on the answer. Some recommend abandonment of Token Ring as soon as possible and move to Ethernet. Others suggest that Token Ring is strategic and one should stay with it forever. Ultimately, one...
متن کاملMultiple Logical Token-Rings in a Single High-Speed Ring*t
The present paper describes a new media access control protocol, called the multiple token protocol, for high-speed ring networks. The purpose of this protocol is to increase the throughput under a heavy load and to decrease the access delay under a light load ofthe token-ring protocol. The protocol maintains several logical token-rings in the single physical ring. The number of logical rings c...
متن کاملComparing Ucn with Fddi and Dqdb Using a Realistic Workload Model
The token ring FDDI and the slotted bus DQDB are the two currently most important standards for high speed networks. Each of these networks has its own specific advantages and disadvantages, and its own specific type of load for which it petforms best. We propose a new network design, called Universal Channel Network (UCN). UCN is adaptive and can be made to behave either like a token ring, a s...
