Development of a Packet-Switched Public computer Communication Network -PART 1: KORNET Overview and Development of Network Management Center

Packet Switching에 의한 공중 Computer 통신망 개발 연구 -제1부: Kornet 개요 및 NMC 개발

This is the first part of the four-part paper describing the development of a packet-switched computer network named the KORNET In this paper, we present the overview of the KORNET, and discuss various aspects on the development of the netwo management center (NMC). The NMC acts as a nerve center of the network, performing such functions as network monitoring, subscriber and network management and routing manage-ment using operator dialogues. In the implementation of the NMC, we have developed various application softwares that include operator interface, primary/srcondary pan, session layer and packet level adaptor. As for packet, link and physical level protocols, we have modified the XODIAC X.25 originally developed by Data General, Inc. All the net-work protocols we have developed comply completely with the CCITT recommendations.

본 론문은 packet 교환 방식의 computer 통신망인 KORNET 개발에 판한 4편의 논문중 제1부로서 KORNET의 전체적인 개요와 network management center(NMC)의 개발에 관하여 기술하였다. NMC는 operator dialogue를 통하여 network내 여러 소자의 상태를 감지 하고 가입자와 network의 운용을 담당하며 routing의 관리를 담당하는등 network의 중추적 기능을 구행한다 본 KORNET의 구현에 있어서 통신 protocol은 CCITT의 권고사항을 충실히 따랐으며 NMC의 응용 software인 operator interface, prinary/secondary부, session layer차 packet level adaptor는 자체적으로 개발하였고, packet, link 및 physical level protocol은 Data Goner각사에서 개발한 XODIAC X.25를 응용하여 개발하였다.
