Abstract

This paper presents a topology based on packet tracer and a five-step scenario model to make it easier for students to understand the network on which VLANs are applied. Virtual LAN (VLAN), developed as an alternative solution to the Routers that distribute broadcast traffic, is a virtual local area network that logically configured regardless of the physical network. The VLAN prevents the network performance degradation resulting from the broadcast traffic by dividing the broadcast domain so that the bandwidth can be used more efficiently. In addition, it enhances the security because on communication between the devices belonging to different VLANs is impossible. The five-step scenarios in this paper presented an efficient implementation case for students to understand and validate the various functions of VLANs through ping/telnet/tracert test and simulation, after setting up each step of programming switches and routers in the virtual network.

Broadcast traffic을 분산하는 라우터의 대체 솔루션으로 개발된 VLAN(Virtual LAN)은 물리적인 망과 무관하게 논리적으로 구성하는 가상 근거리 통신망으로, Broadcast domain을 분할하여 Broadcast traffic으로 인한 네트워크의 성능저하를 막을 수 있어 대역폭을 보다 효율적으로 사용할 수 있으며, 서로 다른 VLAN에 속한 장비들 간의 통신이 불가능하므로 보안 강화에도 도움이 된다. 본 논문은 학생들이 VLAN이 적용된 네트워크를 보다 쉽게 이해할 수 있도록 패킷 트레이서에 기반 한 토폴로지와 이를 구현하기 위한 5단계 시나리오 모델을 제안하였다. 또한 시나리오 별로 가상 망을 추가로 설계해 가면서 스위치와 라우터를 설정하고 ping/telnet/tracert test와 시뮬레이션을 통해서 VLAN의 다양한 기능들을 이해하고 검증하는 효율적인 구현사례를 제시하였다.
