The rapid development of broadband business has brought about profound changes in traditional telecom industry and it business. The integration of multiple services and multiple networks has become an irreversible trend. As the main network entity in metropolitan Area Network, the broadband metropolitan area Network will become the host platform of 3G, NGN and ot

Anyone with a longer experience of network failure maintenance is aware that about 75% of the early network failures come from physical connectivity failures, from cable or physical interfaces. With the implementation and execution of the integrated cabling concept, the improvement of manufacturing process, the improvement of cable and interface quality, the rati
Wireless network security has always been a hidden danger. Most home users think that hiding the SSID wireless network ID can greatly improve network security. In fact, this idea is wrong, the hidden SSID wireless network ID cannot avoid intrusion and scanning problems, today, I will show you how to crack the real
IP address, subnet mask, network number, host number, network address, host address, IP address
IP Address: 4-segment decimal, 32-bit binary, for example, 192.168.1.1 binary is: 11000000 | 10101000 | 00000001 | 00000001The subnet mask shows how many bits are the network number and how many bits are the host number.: 255.255.255.0 binary: 11111111 11111111 1111111
A total of 2 servers, respectively, a, B. A dual network card, that is, there is an intranet network. B only intranet environment. A, B's intranet is built through a switch. As for the external network how to build I will not say. The key is to say how the intranet is formed.If you are unfamiliar with Linux, you may step on a lot of holes if you are unfamiliar wi

I. Concept of Computer Network
What is computer network?
A computer network connects multiple computers distributed in different geographical locations and operated independently using communication devices or lines, A fully functional network software (such as network proto
Implement a two-way NAT virtual network card, nat virtual network cardProblem description and solution are still old problems. NAT configured through iptables in Linux cannot be used in two-way communication environments, you cannot configure a NAT rule to perform NAT on the traffic actively initiated in both directions. There are several solutions to this problem:1. the NAT configuration of the two NAT rul
Get Network Connection StatusWith the promotion of 3G and WiFi, more and more Android applications need to call network resources and detect the network connection status becomes the necessary function of network application.The Android platform provides the Connectivitymanager class for detection of
, the objective function of SVM is still convex. Not specifically expanded in this chapter, the seventh chapter is detailed.Another option is to fix the number of base functions in advance, but allow them to adjust their parameters during the training process, which means that the base function can be adjusted. In the field of pattern recognition, the most typical algorithm for this method is the forward neural network (Feed-forward Neural Networks, h

OpenStack's Neutron can manage Virtual Network Infrastructure (VNI) and physical network infrastructure (PNI) in the OpenStack environment ). OpenStack's Neutron
Network Telephony Application of network developmentFirst, the original telephone communication introductionWe are familiar with the telephone communication methods, generally there are two kinds. One is a wired landline, the other is a wireless mobile phone (where I see wireless landline phones as a landline). Although the two kinds of telephone communication in different ways, but all in people's communic

Performance of network protocolsNow it's our turn to actually control things.The performance of network processing is not proportional to the addition of delay time.This is because the intrinsic operation of most network protocols is bidirectional information exchange.The remainder of this chapter focuses on understanding why these exchanges of information are ge
The wireless network networking strategy helps college students build their networks and master the following knowledge points about the wireless network networking strategy. You only need to spend a few minutes to learn about the wireless network networking strategy. IP address connection, local connection will also be mentioned in this article.
