단순 운영 실험에서 벗어나 시뮬레이션을 한 단계씩 수행하는 simulation 모드 사용법에 대한 설명을 포함하고 있으며 이 때 전달되는 메시지의 헤더 구조와 각 필드를 분석하는 방법도 함께 제시하고 있어 실제 컴퓨터 네트워크에서 진행되는 동작 과정과 메시지를 비교해 프로토콜의 심도있는 이해를 도울 수 있다. 이 책의 마지막에는 스마트 폰에서 네트워크 운영 실험을 해볼 수 있는 모바일 패킷 트레이서 설치 및 운영 방법, 실험 시나리오를 포함하고 있으며 최근에 크게 이슈가 되는 IoT 장비의 운영 방법과 실험 내용도 포함하고 있다. 따라서 이 책을 활용하는 컴퓨터 네트워크 전공의 학생 및 실무 연구자들이 필요한 모든 내용을 망라하였으며 향후 IT 전문가로 성장할 수 있도록 도와줄 수 있을 것이다.
