초록

인터넷의 규모가 급성장하면서 IPv4 주소는 고갈되었고 IPv6로의 전이는 지연되고 있다. 차선책으로 IPv4 주소공간의 낭비를 줄이기 위하여 공중망과 사설망을 연결하는 네트워크 주소변환(NAT : Network Address Translation) 방안이 사용되고 있다. 본 논문에서는 주소공간을 효율적으로 사용할 수 있는 동적 NAT과 PAT 기반의 네트워크 설계를 기존의 이론중심에서 탈피하기 위해 토폴로지 설계 후 패킷 트레이서를 이용하여 공통 가상 망을 구현하고 시뮬레이션을 통해 결과의 검증이 가능한 효과적인 구현사례를 제시하였다.

As the size of the internet market grows rapidly, the number of IPv4 addresses available is being exhausted, while transition to IPv6 is being delayed. As the best alternative solution, Network Address Translation(NAT) scheme is being used. It connects the public internet network with the private internet network in order to reduce the waste of IPv4 addresses space. The purpose of this paper is to study the effective example of network based on common virtual network using Packet Tracer with topology designed rather than usual theoretical approach in Dynamic NAT and PAT, which allows more efficient use of address space.
