Token Ring Network

They were at one time extremely popular but their popularity has since been overtaken by ethernet.

Token ring network. There were several other earlier implementations. Token ring networks prevent data packets from colliding on a network segment because data can only be sent by a token holder and the number of tokens available is controlled. Token ring is a computer networking technology used to build local area networksit uses a special three byte frame called a token that travels around a logical ring of workstations or servers. A token ring network is a local area network lan topology where nodesstations are arranged in a ring topology.

Token ring ist eine vernetzungstechnik fuer computernetzwerke festgelegt in der spezifikation ieee 8025sie definiert kabeltypen und signalisierung fuer die bituebertragungsschicht paketformate und protokolle fuer die medienzugriffskontrolle media access control macsicherungsschicht des osi modellssie ist eine der beiden realisierungsformen des token passing verfahrens. To prevent congestion and collision a token ring topology uses a token to ensure that only one nodestation on the line is used at a time thereby easily denoting media users of its activity. The most broadly deployed token ring protocols were ibms released in the mid 1980s and the standardized version of it known as ieee 8025 which appeared in the late 1980s. Token ring networks cope well with high network traffic loadings.

Ein token ring netzwerk ist ein local area network lan in dem alle computer in einer ring oder stern topologie verbunden sind und ein bit oder token passing system token weitergabe. Token ring networks were developed by several manufacturers the most prevalent being the ibm token ring.
