Remember the experiment of sunlight through a prism? The white light passes through the prism and is decomposed into a variety of colors that gradually transition to the color spectrum, followed by red, orange, yellow, green, green, blue, purple, and this is the visible spectrum. It is clear that the prism separates the mixed things. Today's wireless network is like a bunch of white light, users do not seem to feel the difference at the end, but if t

first, the formation of computer network architecture 1, why layering? when dealing with complex systems: A clear structure allows us to define a specific part of a large complex system and explore its various parts of the relationshipModularity makes system maintenance and upgrades simple Change the specific implementation of one layer of service transparent to the rest of the system (no impact)e.g. cha

When the network architecture of the data center is restructured The network is the "highway" of the amount of data in the data center, and the construction of these "highways" must be planned and designed in a unified manner to give full play to the advantages of network interconnection. A

large quantities of different types of information between various types of service devices has become a huge challenge for the network. 2. Overlapping Service Processing Methods in traditional network architecture As a terminal device that provides services directly, the designer develops and uses the corresponding physical interfaces and communication protocol

If only literally, data center Fusion network architecture is not so easy to understand, fusion itself is a hot word, many occasions are in use, from the three network fusion, technology integration to storage integration, everywhere in the fusion, then, what is the so-called fusion network? Aside from the question of

The presence of FCoE in the storage field has caused a stir. In order to make it healthy and fast forward, the FCOE standard was introduced in June 09, which indicates that this technology will be more mature to the data Center storage transport protocol to lead the goal of the advance. Like many of the new technologies of the past, there are some positive fcoe, some people watching and others dismissive. However, most people are still looking forward to FCoE, but it is still a while before it w

) computer network architecture:In the basic concept of computer network, the hierarchical architecture is the most basic.网络协议：The computer network is composed of multiple interconnected nodes, and the data and control information are exchanged continuously between nodes. To be able to exchange data methodically, each

Abstract: This article reviews common methods for monitoring, maintenance, and system recovery, at the same time, we will explore more effective methods to meet the increasingly urgent requirements of network evaluation goals-reduce costs while improving the business level and production capacity. This article also introduces the principle of remote IT management and the basis of next-generation network fac

a matter of annoyance. Today, it's not just cloud computing that moves applications to the cloud, but also the evolving architecture of applications, including Docker,DevOps, and so on that are sweeping the application development community. Of course, how to quickly deploy an ever-increasing number of mobile applications, and the associated technologies are changing. These changes have brought great pressure on the

Detailed explanation of the network architecture VL2 of the data center, and detailed explanation of the vl2 of the data center I. background With the development of network technology, data centers have become the infrastructure for providing IT network services and distributed parallel computing. The data center is

This month, Nicira Networks suddenly released a new network virtualization architecture and software, announcing the success of copying VMware in the server field. The company has been carefully planning its own development. After four years of operation, it not only released a network virtualization platform, but also published the names of several mainstream co

prone to interference by the electric field and error occurs. The brightness intensity of optical fibers indicates 0 and 1, while that of wireless cables is 0 and 1 with the strength of electromagnetic waves, it is prone to electromagnetic interference and an error occurs. 2) packets are lost (congestion) 3) links and node failures The link may be disconnected. If a node, such as a router, is out of service or the device fails 4) messages are delayed The packet is bypassed in the

The network game structure is divided into the client and the server side, the client uses the 2D drawing engine or the 3D drawing engine to draw the real-time picture of the game world, the server side is responsible for responding to all client's connection request and game logic processing, and control all the client's game screen drawing. Client and server through the network packet interaction to compl

When it comes to Linux operating systems, you cannot fail to mention network technology. The Linux system itself is a network of products, it can be on the network for people to download freely, and be modified and perfected. The Linux system supports a variety of network protocols, and its shell provides powerful netw

With the rapid popularization of Internet applications, the relationship between people and networks has become increasingly close. However, due to the openness and interconnectivity of the Internet, there are many insecure factors in the network, malicious software attacks, and hacking behavior seriously threaten people's interests and security. Therefore, we need a solution that can protect computers against malicious attacks and provide security fo

1. Background and objectives The traditional UMTS wireless communication network is basically designed around the core of the voice service, from the development of 3G, LTE and 4G technology in the future, we can all see that the data service driver plays an important role in the change of network architecture. In the future, communication networks will not only

understand that they are responsible for their actions, everyone knows what to do without the rules of red tape, because when every Chinese goes to primary school, the teacher teaches everyone: what can be done and what cannot be done. In the absence of regulation, the vast majority of people will: do what they want to do. Enterprises, Governments and schools all need order and discipline. Napoleon, who had thought of Britain's greatness, said: "Britain is strong not because of democracy and f
