Abstract

The invention concerns a network node computer (front-end computer, FE) for networking micro-computers, mini-computers, terminals or other data terminal equipment (DTE). So that the DTEs of different manufacturers can be networked into an open local network, the invention proposes that: in each FE, the network node function is present for all DTEs connected to this FE the FE hardware and software are in modular form the FE can be adapted by appropriate plug-in modules to any DTE configuration which is to be connected the FE can be adapted by appropriate plug-in modules to any network topologies, particularly ring, bus, star or mesh the FE can be adapted by appropriate plug-in modules to various transmission media, particularly multiwire lines, coaxial cables or light guides the lower protocol functions, particularly the lowest six levels of the ISO layer model, are shifted to the FE.

Description

Netzknotenrechner Network node computer

Die Erfindung betrifft einen Netzknotenrechner (Front-End-Rechner FE) zur Vernetzung von Mikrorechnern, Minirechnern, Terminals und anderen Datenendgeräten (DEE).The invention relates to a network node computer (front-end computer FE) for networking microcomputers, mini-computers, terminals and other data end devices (DEE).

Nach dem Stande der Technik sind Mikrorechner, Minirechner, Terminals und andere Datenendgeräte in der Regel nur dann miteinander vernetzbar, wenn sie von ein und demselben Hersteller stammen. Die Vernetzung von DEE verschiedener Hersteller ist demgegenüber, soweit überhaupt möglich, mit einem außerordentlich hohen Aufwand verbunden.According to the state of the art, microcomputers, minicomputers, terminals and other data terminals can usually only be networked with one another if they come from the same manufacturer. The networking of DEE from different manufacturers on the other hand, if at all possible, involves an extraordinarily high level of effort tied together.

Es ist deshalb Aufgabe der Erfindung, einen Netzknotenrechner zu schaffen, mit welchem die DEE verschiedener Hersteller zu einem offenen lokalen Netz (Local Area Net LAN) vernetzt werden können. Dieses LAN wird als "offen" bezeichnet, weil die DEE beliebiger Hersteller anschließbar sind.It is therefore the object of the invention to create a network node computer, with which the DEE of different manufacturers to an open local network (Local Area Net LAN) can be networked. This LAN is said to be "open" because the DEE from any manufacturer can be connected.

Zur Lösung dieser Aufgabe schlägt die Erfindung Netzknotenrechner FE vor, die dadurch gekennzeichnet sind, 1. daß in jedem FE die Netzknotenfunktion fUr alle an diesen FE angeschlossenen DEE bereitgestellt ist, 2. daß der FE in Hard- und Software modular ausgebildet ist, wobei 2.1. der FE durch entsprechende Steckmoduln an beliebige anzuschließende DEE-Konfigurationen anpaßbar ist, 2.2. der FE durch entsprechende Steckmoduln an beliebige Netztopologien, insbesondere Ring, Bus, Stern oder Masche anpaßbar ist und 2.3. der FE durch entsprechende Steckmoduln an unterschiedliche Übertragungsmedien, insbesondere Mehrdrahtleitungen, Koaxialkabel oder Lichtleiter, anpaßbar ist, 3. und daß weiterhin die unteren Protokollfunktionen, insbesondere die unteren sechs Ebenen des IS0-Schichtenmodells, in den FE verlagert sind.To solve this problem, the invention proposes a network node computer FE before, which are characterized in that 1. that the network node function in each FE is provided for all DTEs connected to this VU, 2. that the VU in hardware and software is modular, with 2.1. the FE through appropriate plug-in modules can be adapted to any DEE configuration to be connected, 2.2. the FE through corresponding plug-in modules to any network topology, in particular ring, bus, star or mesh is adaptable and 2.3. the FE through appropriate plug-in modules to different Transmission media, in particular multi-wire lines, coaxial cables or light guides, is adaptable, 3. and that the protocol functions below, in particular, continue to be used the lower six levels of the IS0 layer model into which FE are relocated.

Durch das unter 1. angegebene kennzeichnende Merkmal der Erfindung ergibt sich der Vorteil, daß zwischen allen am gleichen FE angeschlossenen DEE kommuniziert werden kann, ohne daß hierdurch das Netz belastet wird. Aufgrund der kennzeichnenden Merkmale 2. kann der FE auf einfache Weise an die Besonderheiten der einzelnen DEE bzw. des Netzes angepaßt werden. Das kennzeichnende Merkmal 3. bewirkt, daß die anzuschlie- ßenden DEE nur geringfügig ergänzt zu werden brauchen.By the characteristic feature of the invention specified under 1. there is the advantage that communication between all DTEs connected to the same VU without loading the network. Because of the characteristic Features 2. the FE can easily adapt to the special features of the individual DEE or the network can be adapted. The characteristic feature 3. causes the to be connected ßenden DEE only need to be supplemented slightly.

Es genügt nämlich ein Punkt-zu-Punkt Protokoll zwischen DEE und FE.A point-to-point protocol between DEE and FE is sufficient.

Zweckmäßig sind der FE und die Steckmoduln in VLSI-Technik ausgeführt.The FE and the plug-in modules are expediently designed using VLSI technology.

Weitere Einzelheiten der Erfindung ergeben sich aus der anliegenden, noch nicht veröffentlichten Dissertation des Herrn Dipl.-Ing. Tomalla, die Bestandteil der vorIiegffiend#n Patentanmeldung ist. Further details of the invention can be found in the attached, as yet unpublished dissertation by Dipl.-Ing. Tomalla, which is part of the previous patent application.
