Wired networks have always been a frequent network type for home and enterprise users. However, with the popularity of wireless networks, wired networks gradually expose their inevitable drawbacks: a large number of cabling and line change projects; lines are prone to damage; nodes in the network cannot be moved. In particular, when connecting distant nodes, it i

management, mobility management and call control functions, including location update, authentication, call, paging, switching, etc. The terminal and network are identified by PSNumber (equivalent to IMSI in GSM). The wireless network includes the base station and the base station controller, connect to the core network through the interface. ZTE's PHS System is a mobile network system based on the GSM network architecture, including MSC/VLR (IGW) and HLR. The A interface evolved from the gsm b

Although, at present, 3G wireless communication networks have not been applied to every mobile user as expected. However, the author believes that this is only a matter of time, and does not prevent us from looking forward to the bright future of 3G wireless communication networks. 3G has set a new goal for itself-digital intelligence for our lives. China Unicom is setting a new goal for 3G business applica

Definition of energy efficiency in communication networks and its value for energy-saving management across the network Improving the energy efficiency of communication networks (EE) is an important means to improve the profitability of operators. The energy efficiency indicators are further divided into TEE and IEE) it can better adapt to the organization model of Maintenance Management for telecom operat

Label: style blog HTTP Io SP strong on 2014 Preface: Keep your style consistent. Before you officially start writing, start with a long talk. There are too many books and articles about neural networks, so I am not allowed to talk about them in a word that is too arrogant. I try to write a little more information. After reading this article, I can have a general understanding of neural networks and have so

The first time consisted of learning how to does machine learning in a week.This time I ' ve tried to learn neural networks. While I didn ' t manage to does it within a week, due to various reasons, I did get a basic

1. Introduction Automatic Switching Optical Network (ASON) technology has been accumulating and improving after years of development. For most carriers in China, Traditional transmission networks already have a large scale. How to introduce ASON technology more rationally to achieve stable evolution of transmission networks is the main issue discussed in this article. 2. Introduction of ASON technology At p

Broadband access networks are worth learning. Here we mainly introduce the Network Positioning of broadband access servers and the system requirements of broadband access servers, including the extended functions of broadband access servers. With the increasing process of broadband data networks, Wide Area Network broadband access technology, represented by xDSL, HFCs, and even optical fiber LAN, has develo

In order to adapt to the rapid development of data services represented by IP Services and the trend that the data business volume will exceed or greatly exceed the voice business volume; to adapt to the changes in network traffic distribution caused by customer-server and other application methods, as well as the unique self-similarity of IP Services and the asymmetry of sending and receiving, to support an endless stream of online applications, all countries in the world are exploring and expe

allow third parties to provide services.As the core of the Next Generation Network, Softswitch technology combines the reliability of traditional telephone networks with the flexibility and effectiveness of IP technology, and has become a hot topic in the field of communication. As 3G approaches, mobile networks and fixed networks introduce the design concept of

switches.There have been a lot of discussions about vswitches, and people have basically agreed on the technical characteristics of vswitches. Vswitches use MGCP/H.248 media control protocol technology to separate call control from media bearer. Therefore, some foreign scholars refer to soft switches as call proxy CA or media gateway controller MGC. The concept of a soft switch not only makes the voice service function of the Next Generation Network completely transparent and compatible with th

protocol-based networks. Limitations on video compression over IP Networks 1. H.264 application scenarios Before discussing IP-based H.264, it is necessary to describe the application scenarios of H.264 related to IP networks and their requirements for transmission and decoder. The following describes three scenarios: Dialog application, download service, a

convolutional Neural Network (convolutional neural networks/cnn/convnets)Convolutional neural networks are very similar to normal neural networks: the neurons that make up them all have learning weights (weights) and biases (biases). Each neuron accepts some input, performs a dot product operation, and may execute a nonlinear function to finally get the output of

Today, I installed the virtual machine to play, downloaded the Ubuntu server 14.04 image, and then made a template. After the template is deployed as a virtual machine, the network of the returned virtual machine is not available, here I choose the bridge mode, using ifconfig found no IP address, finally found a solution, and now recorded:Keep the last line, all of the previous delete or comment, and change the name of the last line to eth0, save and restart the line.Mac uses parallels to clone

bias is used to measure the ability of an independent variable in a multivariate function to influence the function value. A gradient is a vector that points to the value of the function to increase the fastest direction. The chain rule is that, for a composite function, the derivation process can be part of a part, and then "linked" up. Vectors can be thought of as a special form of a matrix. Matrix multiplication is closely related to linear systems. The Ndarray in the Num
