In addition, ...

The development of mobile devices such as smartphones has also spawned too many app "TechWeb reports" that were repeated in the mind before writing this article: the progress of technology makes life more and more beautiful, indeed, the development of science and technology has brought us closer to the world, with the network, Mobile Intelligent terminals, powerful software to form a vast expanse of ecological communication circle, so that we can not leave home to understand the global real-time news, in fact, now we live, work and learn more in the enjoyment of technology to bring convenience, now everywhere without technology ...

The threat of DDoS (Denial-of-service attack) at the application level is more dangerous for data center operators. Because the state detection design of IPS devices and firewalls encounters this new attack tactic, a large increase in status requirements becomes more vulnerable, making the device itself more vulnerable to attack. In addition, the current protection measures based on boundary network have a big gap if they want to use cloud computing to solve DDoS attacks, using the DDoS infrastructure of the service provider or the dedicated DDoS attack protection in the upstream of the victim's infrastructure. The current solution is not good ...

"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 achievements of modern science and technology make the human organs in space has been greatly extended, if the telephone is the extension of human voice, television is the extension of human vision, the data center is the extension of the human brain, then the network is a variety of extensions, as well as between the extension and the subject exchange information between the transmission of the instructions of the nervous system. The normal nervous system is one of the basic signs of a healthy human being, similarly, the large bandwidth, the low time delay, the high reliable network system is also makes the human various organs to extend effectively, enters the cloud age the basic guarantee. Cloud business's challenge to the network as information services enter ...

Overview The key information maintained by the control plane is the network state. The control plane must aggregate this information and make it available to the application. In addition, in order to maintain scalability and component reuse, applications should be exempt from protocol details, even though network state information is obtained through a specific protocol. The Onos topology of the protocol is implemented by two complementary mechanisms: Network Discovery and configuration. The former uses the network protocol to let Onos identify the location and/or performance of the network elements, and take the initiative to carry out the relevant collection work when the function is enabled. The latter allows applications and operations ...

1. Research background cloud Computing is the product of Grid computing, distributed computing, parallel computing, utility computing, networked storage, virtualization, load balancing, and the development of traditional computer technology and network technologies. With the help of SaaS, PaaS, IaaS, MSP and other advanced business models, this powerful computing power is distributed to the end-user. 　　The core idea of cloud computing is to manage and dispatch a large number of computing resources with network connection, and form a computing resource pool to serve the users on demand. As cloud computing gradually becomes ...

Author: Our correspondent Chianglong this year, the operators of the transport network planning and deployment should be carried out in order to host the entire business as the goal, so as to adapt to voice services, data Services, multimedia services, such as the requirements of a variety of services to provide flexible, efficient and reliable bandwidth.　　Experts from China Mobile Research Institute believe that, in 2010, OTN as Backbone network technology, will be driven by the whole business to usher in more commercial opportunities. The standard for all-service bearer optical transport network (OTN), as a large capacity optical transmission technology, has become the core technology of the next Generation transmission network. But like the ...

With the rise of new businesses such as cloud computing, mobile Internet and Web2.0, traditional data centers have been unable to meet. The industry is setting off a new wave of data center construction, with the next generation of cloud computing data centers. Network is one of the important components of cloud data center, the network Architecture of cloud data center must have five new technology features: 100G Ethernet technology, surge cache, network virtualization, unified Exchange, green energy-saving technology. 100G Ethernet Technology Bandwidth pressure is the core problem of cloud data center network. In the data center, like video-on-demand, 10G FCoE ...
