The scheme is named the spiral topology because the architecture is built around modules of four computer nodes each, connected by top and bottom spirals. The spiral topology features a simple internal self-routing algorithm that adapts quickly and automatically to failed computer nodes or links. The six most important direct consequences of the network architecture are (1) ease of expansion, (2) fast, on-the-fly self-routing, (3) extremely high tolerance to failed network nodes or links, (4) increased network security, (5) potential for the total elimination of store and forward transmissions due to routing decision delays, and (6) rendering the maximum-path-length issue moot.(4 refs)Controlled terms: - Data Transmission - Electric- Decision Delays - Self Routing Algorithm - Spiral Topology - Store and Forward TransmissionsTreatment: Theoretical (THR)Database: CompendexAccession number: 1990035210067Title: Fault-tolerant analysis of the spiral computernetwork topologyAuthors: Mitchell, Tony L.1; Nilsson, Arne A.1Author affiliation: 1USAF Acad, Dep of Math Sci, Colorado, Springs,CO, USACorresponding author: Mitchell, Tony L.Source title: Conference Record - International Conference onCommunicationsAbbreviated source title: Conf Rec Int Conf CommunVolume: 1Issue date: 1989Publication year: 1989Pages: 363-367Language: EnglishISSN: 05361486CODEN: CICCDVDocument type: Conference article (CA)Conference name: IEEE International Conference on Communications -ICC'89Conference date: June 11, 1989 - June 14, 1989Conference location: Boston, MA, USAConference code: 12791Sponsor: IEEE, Communication Soc, New York, NY, USA;IEEE, Boston Section, Boston, MA, USAPublisher: Publ by IEEE, Piscataway, NJ, United StatesAbstract: Results are presented from the analysis of acomputer network topology that has the potential tobecome a standard in future years.
