Abstract

PURPOSE: A network interface card having functions for booting and network computing is provided to enable a computer to boot by driving an OS(Operating System) of network interface card instead of HDD(Hard Disk Drive) and to realize a thin client/server system through networking by using a thin client program. CONSTITUTION: The network interface card(10) consists of a memory(13) storing an OS to boot a computer, a decoder(12) decoding an address in order to recognize the memory as a hard disk and a controller(14) interfacing a server(20) by equipping a cable port(15). The network interface card drives by inserting to an ISA(Industry Standard Architecture) slot of a PC, especially an outmoded 486 or 586 type PC. At booting, the decoder makes the memory be recognized as a hard disk by not using A or C drive but a memory address D8000. The memory may use a flash memory and stores an OS for booting and a network program for networking to a server system.

부팅기능 및 네트워크 컴퓨팅 기능을 갖는 네트워크 인터페이스카드{Network interface card having function of booting and network computing}Network interface card having function of booting and network computing

본 발명은 네트워크 인터페이스카드에 관한 것으로, 특히 개인용 컴퓨터(PC)의 아이사(ISA)슬롯에 장착되어 네트워크 컴퓨팅과 함께 부팅(booting)기능을 갖는 인터페이스카드에 관한 것이다.The present invention relates to a network interface card, and more particularly, to an interface card mounted on an ISA slot of a personal computer (PC) and having a booting function with network computing.

기존의 클라이언트/서버(Client/Server) 방식의 경우에는 많은 작업들이 클라이언트 컴퓨터 상에서 처리가 되므로 네트워크를 이용하여 정보를 공유하고 작업을 수행하기 위하여 높은 성능의 클라이언트 컴퓨터, 즉 패트 클라이언트(FatClient)화 되어 많은 유지 및 관리를 필요로 하며, 이에 따라 사용자 친숙성이 떨이지게 되며, 많은 설치비용이 요구되게 된다. 최근에는 이와 같은 패트 클라이언트/서버(Fat Client/Server) 시스템을 지양하며, 기존 클라이언트/서버 방식에서 클라이언트에게 분담되었던 어플리케이션 부하를 서버에 집중시키는 씬 클라이언트/서버(thin Client/Server) 시스템 방식의 활용이 늘어나고 있다. 상기 씬 클라이언트(Thin Client)란 TV처럼 편하게 쓸 수 있는 컴퓨터 단말기로서, 개인용 컴퓨터(PC)에 비하여 칩과 메모리등 하드웨어를 혁신적으로 줄임에 따라 적은 관리 및 유지비용, 사용자 친숙성이 우수하며, 높은 독립성과 신뢰성을 가지는 장점이 있다. 이와 같은 씬클라이언트/서버 시스템을 위한 소프트웨어로는 씨트릭스(Citrix)에서 제공하는 메타프레임(MetaFrame)이 있다. 상기 메타프레임의 구성은, 어플리케이션을 구동하며 시스템 상태를 모니터링하는 관리(management)기능과, 이기종 컴퓨터 환경을 통합하며 서버에 접속기능을 수행하는 접근(access)기능과, 아이씨에이(ICA; Independent Computing Architecture)를 이용한 네트워크 상황에서의 최적화된 어플리케이션을 수행하여 데이터압축의 최적화 등을 수행하는 실행(performance)기능과, 사용자 인증 등과 같은 보안을 수행하는 보안(security)기능으로 구성되어 씬클라이언트/서버 시스템을 구성할 수 있도록 한다.In the case of the conventional client / server method, since many tasks are processed on the client computer, a high performance client computer, that is, a fat client, is used to share information and perform work using a network. It requires a lot of maintenance and management, which leads to a loss of user friendliness and a large installation cost. In recent years, such a fat client / server system has been avoided, and a thin client / server system method that concentrates application loads distributed to clients in a conventional client / server system on a server is utilized. This is increasing. The thin client is a computer terminal that can be used as comfortably as a TV. Innovatively reduces hardware, such as chips and memory, compared to a personal computer (PC). And has the advantage of having reliability. Software for such thin client / server systems includes MetaFrame, which is provided by Citrix. The metaframe consists of a management function that runs an application and monitors system status, an access function that integrates heterogeneous computer environments and accesses a server, and Independent Computing (ICA). Thin client / server system that consists of a performance function that performs optimization of data compression by performing an optimized application in a network situation using an architecture) and a security function that performs security such as user authentication. Allows you to configure
