Abstract

The present invention relates to a network interface card controller and method of controlling thereof, capable of supporting several types of protocols. The present invention provides an integrated hardware card which supports an interface of several protocols. Thereby, the structure becomes simple and the cost may be reduced. The network interface card(hereinafter, referring to NIC) controller, which is controlled by a central processing unit(CPU) in which a network interface function and a protocol process function are connected to a network, comprising a plurality of protocol process means of respectively providing a several types of protocol for offering any service required from the CPU through a system bus, plurality of network interface means of performing a desired network interface by switching a digital highway according to service types required from the CPU through the system bus, and of performing a digital relay which occupies an empty trunk line, in which the plurality of network interface means are connected to several trunk lines of a physical layer, and call control means of controlling the plurality of protocol means and the plurality of network interface means regardless of protocol types, by exchanging information with an upper application layer, by using a standard interface indicating whether the process succeeds or not about a protocol process request and the requested protocol process result.
