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

Wireless Internet is the most disturbing is the network limited situation, the wireless network may connect, the signal is also very good, is not on the net. The signal on the wireless network has a yellow exclamation mark on it, but it's not on the net. In fact, this problem for the wireless network is still very comm

TUN/TAP Virtual Network device provides the ability to send and receive network packets for user-space programs. He can be either a point-to-point device (TUN) or an Ethernet device (TAP). In fact, not only does Linux support TUN/TAP virtual network devices, but other UNIX is supported, and there is only a slight difference between them. Tun/tap Virtual

1.CDNThe principle is to avoid the internet will affect data transmission speed and stability of the link, make access faster.The goal is to give users access to the nearest data, improve Internet speed and solve the problem of network congestion.CharacteristicsBandwidth optimizationCluster anti-attack effectively prevents hackers from DDoS attacksRemote acceleration speeds up remote accessLocal cache acceleration to increase access speed and stabilit

Differences between indoor and outdoor Network cables and Network Cabling Process Differences between indoor and outdoor Network cables As the name suggests, an outdoor network cable is a cable used outdoors. An indoor network cable is mainly used in an indoor

In small and medium enterprise network interconnection, there are many connections using Frame Relay networks because the transmission mode is similar to a leased line and supports Traffic Transmission. If it is a frame relay network, then, the interfaces connecting the vswitch are all various frame relay nodes. In this way, multiple virtual connection channels are formed and attached to a

Normally, when 3G and WiFi are on, Android uses Wi-Fi by default, but it is not possible to have WiFi everywhere in the real world, so the phone will often automatically switch networks.Sometimes, when the phone starts using WiFi, it will automatically switch from WiFi to 3G network 10-30 minutes after it enters standby.If you write a network program, the effect of automatic

-cognitive machine (Neocognitron) proposed by Japanese scholar Kunihiko Fukushima has enlightening significance. Although the early forms of convolutional networks (Convnets) did not contain too many Neocognitron, the versions we used (with pooling layers) were affected.This is a demonstration of the mutual connection between the middle layer and the layers of the neuro-cognitive machine. Fukushima K. (1980) in the neuro-cognitive machine article, the self-organizing neural

Note: 1. This document describes how to set up the Network Analysis Service. Therefore, I will not discuss in depth every detail of the Network Analysis Service. The purpose of this article is to let beginners learn how to use the network analysis service for Basic Analysis (mainly for subsequent web development): path analysis, recent facility analysis and servi

Refer to the Internet frequent drop line, I believe that many people will subconsciously think that the fault is due to poor line contact, but in the elimination of line factors, the network frequently dropped the phenomenon will sometimes still appear, when we encounter this phenomenon, in addition to observing the stability of the network equipment itself, Also need to pay attention to whether there are p

One, Win10 can't connect to this network what's going onFor the majority of people who are unable to connect to this network problem, mainly Win10 laptop users, using a wireless network. While the WIN10 connection other wireless network is normal, but is a wireless network c

The access network system is widely used and has been well developed in various fields. It also plays an important role in cable TV return. After more than 20 years of development, China's cable TV network line is now more than 3 million kilometers in length, the optical fiber trunk line reaches 0.26 million kilometers, and nearly 2000 counties have opened cable TV, among them, more than 600 counties have i

The network administrators started their brains and summed up a lot of network troubleshooting skills. However, by carefully reviewing these skills, we can see that some of the troubleshooting skills are performed on the Windows interface. Although these tricks are more convenient for users, it can also effectively improve the efficiency of network troubleshootin

Part 1: Network principle: 1. network addressing (mainly using IP address addressing) 1. IP address addressing is a two-layer addressing solution. an IP address identifies a host (or a Nic interface) 2. Currently, IPv4 addressing is the most widely used address.
