802.5 (Token Ring) networks do not use a ring topology at layer 1. Token Ring networks are technologies developed by IBM typically used in local area networks. Token Ring (802.5) networks imitate a ring at layer 2 but use a physical star at layer 1. "Rings prevent collisions." The term "ring" only refers to the layout of the cables.
Proteon designed and manufactured of some of the earliest commercial local area network and TCP/IP Internet Router products. [1] Although founded in 1972 by Howard Salwen as communications consulting firm, Proteon became a manufacturer when they produced the first commercial Token Ring network interfaces and media access units in conjunction with MIT.

Token Ring is a physical and data link layer computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a token that is passed around a logical ring of workstations or servers.
In a telecommunication network, a ring network affords fault tolerance to the network because there are two paths between any two nodes on the network. Ring protection is the system used to assure communication continues in the event of failure of one of the paths. There are two widely used protection architectures: 1+1 protection and 1:1 ...
The next packets sent by the network can then be flooded and learned out of the (now enabled) secondary port without any network disruption. Fail-over times are demonstrably in the region of 50ms. The same switch can belong to multiple domains and thus multiple rings. However, these act as independent entities and can be controlled individually.
The National Infrastructure for Research and Technology Network or GRNET (Greek: Εθνικό Δίκτυο Υποδομών Τεχνολογίας και Έρευνας, ΕΔΥΤΕ) is the national research and education network - NREN of Greece and was formerly named Greek Research and Educational Network.
The Cambridge Ring was an experimental local area network architecture developed at the Computer Laboratory, University of Cambridge starting in 1974 [1] and continuing into the 1980s. It was a ring network with a theoretical limit of 255 nodes (though such a large number would have badly affected performance), around which cycled a fixed ...
Resilient Packet Ring (RPR), as defined by IEEE standard 802.17, is a protocol designed for the transport of data traffic over optical fiber ring networks. The standard began development in November 2000 [ 1 ] and has undergone several amendments since its initial standard was completed in June 2004.
