Through direct and adress way, The routing table knows that port 4 corresponds to the 1.1.1 network segment and the corresponding IP address is 1.1.1.2, Port 5 knows that the corresponding network segment is the 2.1.1 network segment and its IP address is 2.1.1.2, through the ARP table, the router can know the IP address of the MAC address of its 4.5 port. Host a

The Development of China's wireless mesh network is still very rapid, so I have studied the comprehensive comparison between the Wireless Mesh Network and other access network technologies. I would like to share with you here, I hope it will be useful to you. Wi-Fi is based on the IEEE802.11x standard technology. Currently, Wi-Fi includes IEEE802.11b, 802.11a, an

To form a basic network, you need only one hub (hub) or one switch, several NICs, and dozens of-meter UTP lines to complete.In fact, such a simple network is the basic unit of a more complex network. By connecting these small, simple networks together, they form aMore complex local area networks (LANs).3.1 The simplest network650) this.width=650; "Src=" Http://s5

Theoretical learningQuestion 1: What is the difference between static and dynamic routes? 1> Static routing is a fixed route set in the router , and dynamic routing is performed by the configured dynamic routing protocol for automatic routing calculation and routing table entry updates . 2> Static routing does not work as well as dynamic routingthe 3> Dynamic routing protocol accounts for bandwidth and CPU Resources , and does not have high static routes for execution priority . Question 2: De

Network MonitoringWith the mobile network upgrade: 2G->3G->4G even the development of 5G, the network speed is more and more fast, but this flow is like flowing water generally rushing away.Online is not a joke: sleep forgot to close the flow, the next day the house will be moved!This is an exaggeration to say, but as a good app developer, we need to give the mos

Network optimization is a very important part of all app development, and if the network request is preceded by a click to jump activity, the speed of the network load will be improved. That is, the network pre-load box frame.Network pre-load frame, monitor network pre-load
