**课程名称：数据网络与TCP/IP** **课程概述：** 本课程旨在介绍数据网络的基本理论和TCP/IP协议栈。课程从OSI参考模型和数据结构入手，深入讲解以太网协议、局域网交换技术（包括VLAN、生成树协议和链路聚合）、IPv4协议和寻址（涵盖ARP、VLSM和CIDR）、IP多播、DHCP、NAT（静态和动态）以及路由原理（包括路由器工作方式、路由协议、HSRP/VRRP和三层交换）。 课程将详细解析数据在网络中的传输过程，包括数据包的结构，并通过大量的Wireshark抓包文件实例进行说明。您将学习到： * **网络模型与数据结构：** OSI参考模型和DoD参考模型中的网络层，以及帧、包和消息的结构。 * **网络质量特征：** 带宽、延迟、抖动和丢包率等网络质量特性如何影响应用程序性能。 * **以太网与局域网技术：** 从10Mbps到100Gbps的以太网协议，局域网交换、VLAN、生成树协议和链路聚合。 * **IPv4协议与寻址：** IPv4协议、地址解析协议（ARP），以及可变长子网掩码（VLSM）和无类别域间路由（CIDR）。 * **IP多播与网络服务：** IP多播的工作原理、DHCP的工作流程、以及静态和动态NAT的操作。 * **路由与网络互联：** 路由原理、路由器如何找到目标地址、HSRP/VRRP操作和三层交换。 通过丰富的网络实例、Wireshark数据包分析等教学手段，本课程将为您在数据网络和TCP/IP领域打下坚实的基础。
The Introduction to Data Networking and TCP/IP course presents the basic theory of network hardware and software. It starts with the OSI Reference Model and data structure, explains the Ethernet protocol and LAN switching, continues with the basics of IPv4 operation and addressing, continues with TCP, UDP and how they work and finalize with routers and routing protocols.This course focuses on the understanding on the understanding of data networks. During te course you will learn about how data flows over the network, including the packet structure, illustrated with many Wireshark capture files examples.You will learn about:The network layers in the OSI and DoD reference models, frames, packet and messages and how they are structured.Network quality characteristics, that is bandwidth, delay, jitter and packet loss, and how they influence applications performance over the networkThe Ethernet protocols, from 10Mbps to 100Gbps and beyond, LAN switching, VLANs, Spanning Tree and Ling Aggregation.IPv4 protocol and addressing, Address Resolution Protocol (ARP), including Variable Length Subnet Masks (VLSM) and Classless Inter-Domain Routing (CIDR)IP Multicast and how it works, Dynamic Host Configuration Protocol (DHCP) operation, Static and Dynamic NAT operationRouting principles, how routers find the way to destination, HSRP/VRRP operation and L3 switching.The course brings many examples and illustrations, including network examples, Wireshark packets examples and more, providing you wit a good start in the data networks and TCP/IP worlds.
