Private IP Address要访问public internet需要NAT(network address translation)。 4-5_IP_Forwarding Routing和forwarding的区别:Forwarding是处理接收到的packets送到合适的地方去;routing是计算出网络中所有的路径,之后再来packets就可以forward了。 Network layer要做的是scale to large network,using address with hierarch...
CHAPTER 5 NETWORK LAYER Data Communications and Computer Networks 中国科学技术大学网络学院 李艺 leeyi@ 概述 网络层是OSI参考模型的得三层,它建立在数据链路层所提供的两个相邻的端点之间的数据帧的传送功能之上,将数据从源端经过若干中间的节点送到目的端,从而向运输层提供最基本的端数据传送服务。网络层是处理...
OSI Layer 3 - Network Layer In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers, since it knows the address of neighboring network nodes, and it also manages qualit...
The network layer is layer 3 in the OSI model, and it makes the Internet possible by connecting different networks. It is also called the Internet layer.
In this article, we will talk about the much-asked query of what is layer 2 network is and how its w

Communication from one person to another goes from Layer 7 to Layer 1. Each layer performs a specific job before it sends the data on to the next layer. Layer 7 - Application layer The application layer is the closest to the end-user. It initiates communication between the user and the...
主要讲802.11的phsical layer和link layer。Multiple access uses CSMA/CA,RTS/CTS optional。WiFi和classic Ethernet,the multiple access problem is solved with randomization。AP(Access to the internet)。 3-6_Contention-Free_Multiple_Access Random multiple access在low load下不错。High load下不是很好。讲...
