基于ICMP的网络主机状态判断研究

摘要

ICMP is an important network layer protocol.In this article,through the basic concepts of the ICMP protocol,the main functions and the data structure of the resolution,we make the program developers to master the design of the host scanner in the network environment.%ICMP协议是一种重要的网络层协议。本文通过对ICMP协议的基本概念、主要功能、数据包结构的解析,使程序开发者掌握网络环境下主机扫描程序的设计方法。
