When we talk about how to implement cloud computing, there's a lot of computer resources to manage and share, as well as applications that need to be improved, but there are very few topics and solutions on how to optimize cloud computing. However, when companies are going to decide to use cloud computing on a large scale, we are only focused on recommendations, application management, and major changes in planning - all of which will have an impact on the web. This requires a new approach to cloud computing. Today's network planners realize that "corporate networks" are the true combination of "resource networks" and "access networks." The former connection I ...

"Editor's note" Network after years of development, has come to the "post-Cisco" era, software definition network, network virtualization and other nouns have come to everyone, this article focuses on the traditional network architecture and SDN network of similarities and differences, the development of network virtualization, you can see, SDN manufacturers are gearing up, because of " We usually overestimate the changes in the next two years, and underestimate the changes that will happen in the next decade ", the traditional enterprises need to actively face the future changes in the network operation, the author from the Network Transformation and technology transformation in two aspects of the network industry in-depth discussion of the ...

The popular words in the IT industry often create the illusion that the network virtualization is just the IT industry for the virtual everything derived from the ancillary products, or just a fad. However, we can see that network virtualization has at least three points of benefit and there are several best practices that we should follow. 　　So let's take a look at the significant advantages of network virtualization and its best practices. The advantages of network virtualization first, network virtualization can help better utilize network resources. Sometimes this means that the utilization of physical resources can be improved. For example, you can put a few empty ...

Currently, VoIP faces security issues of four main: blocking service (DoS) attacks, illegal access, charges fraud or eavesdropping threats. VoIP protocol security is not negligible pain. Information security experts will warn you that if you do not deploy VoIP properly, Internet telephony will be attacked by hackers and malicious code. VoIP can disrupt the security of the network, especially for corporate networks, because companies are eager to deploy this technology and ignore security.

On February 3, the Internet Domain name Authority (ICANN) announced in Miami, the United States, that the IPV4 address library has been depleted, a major historical event in the world's Internet. Also means that the next generation of Internet access to ...

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

OpenFlow is the latest internet technology that has recently begun to commercialize the university labs. At the Las Vegas Interop Fair in 2011, the technology was presented as a sensation, and the show was also called the "OpenFlow exhibition". Although the protocol is simple, it will have far-reaching implications for the network architecture and the 16 billion-dollar switch market. We will review the origins of OpenFlow and the various problems it can solve, including its current common architectures, and we would like to know why OpenFlow can be called ...
