Abstract

An Ethernet Communications System, as generally configured, includes the interconnecting cable, work stations and servers. The cable is passive and signals enter and exit through transceivers which can be "tapped" anywhere along the network. Input and output from the cable can be made through a workstation. The experimental "ALTO" system is one such .workstation. The third element is the server. Servers assume that users possess substantial computational power, requiring special data formats and high level communication protocols for their operation.

ETHERNET INTERFACE SERVER (Cont'd)

An Ethernet Communications System, as generally configured, includes the interconnecting cable, work stations and servers. The cable is passive and signals enter and exit through transceivers which can be "tapped" anywhere along the network. Input and output from the cable can be made through a workstation. The experimental "ALTO" system is one such .workstation. The third element is the server. Servers assume that users possess substantial computational power, requiring special data formats and high level communication protocols for their operation. Server examples include large file storage systems, laser printers and communications handlers.

Servers also assume that human operators are not required.

The Interface Server would provide whatever additional computational power is required to connect contemporary products or add system functions to the Ethernet network. It is not a gateway between Ethernet networks or between an Ethernet network and external devices, but a server which is attached to a branch of an E the rne t network.
