Apparatus and method for enabling a network interface to dynamically

Abstract

A network provides the capability for information transfer and resource sharing between a plurality of nodes including computers and peripheral devices. The network is comprised of a plurality of network interfaces coupled together on a network cable in both a daisy chain configuration and a bus configuration. Each node is connected to one of the network interfaces using an interface compatible with each particular node. Each network interface contains logic means for controlling the operation of the network. A means for self-identifying the network address of each node is provided without the need for unique hardware or software in each network interface. One of the network interfaces in the network is self-designated as the network watch dog. The network watch dog performs network error detection and correction. The network provides the capability for nodes to communicate with each other even though their associated interfaces are incompatible. The network also provides a means for performing network protocol conversion necessary in order to allow nodes with incompatible interfaces to communicate. Virtual connections between two nodes may be established whereby uninterrupted information transfer may take place. Particular peripheral devices may be associated with particular computer nodes thereby eliminating the need for a computer node to specify a destination for information transfer. The logic means in each network interface will assign peripheral devices to computers by default.
