As early as 2003, the United States "Technology Review" on the Internet of things related to the sensor network technology as the future changes in people's lives of the top ten technology. The Internet of Things (IoT) is now very hot, in the IoT era, all items are expected to be connected through the information sensor equipment and the network to achieve intelligent identification and management. Currently networked thermostat, hand ring, smart watch and so on while the new products in turn leaped to the headlines, but some of the more significant trends will affect the future shape of the internet of things. The standard certification of Internet of things lags behind the development of technology it seems that the Internet will be like the history of communication technology ...

"Tenkine Server channel August 12 News" At the first Huawei Global Financial Forum held recently, Huawei has been highly appraised in the data center's comprehensive disaster preparedness network delivery solution. 　　Data center has become an important infrastructure to ensure the normal work of the financial information system, how to ensure the continuous and reliable operation of the data center, how to deal with and effectively resolve the risk caused by the data concentration, has become an important issue of concern in the industry. Financial data center development and disaster preparedness demand at present, most enterprises in the financial industry have established data centers, and achieved a large concentration of data, all ...

The switch occupies an important position in the enterprise network, which is usually the core of the whole network. In this era of hacker intrusion and virus-ridden network, as the core of the switch is also taken for granted a part of the responsibility of network security. Therefore, the switch must have the professional security product performance, the security has become the network construction must consider the heavy middle. As a result of security switches, the integration of security certification in the switch, ACLs (Access control list), firewall, intrusion detection and even anti-virus functions, the security of the network really need ...

Just ...

Cloud computing has brought unprecedented challenges to data center networks, which are mainly embodied in network scale, resource virtualization and sharing, and distributed data Center collaboration. First look at the network scale. Cloud Computing Data Center Server size is usually thousands of units, or even tens of thousands of units, and with the development of the business, the scale of the network will continue to expand, with the attendant, cabling network management has become more complex. The traffic flow model is no longer the traditional north-south oriented, high convergence ratio, but with hado ...

Hyper-V is the new concept of a recently virtualized network, with news that many of its most recent features affect network design. In previous articles, we briefly described some improvements in network virtualization and some improvements in virtual machine networks. This article introduces another network improvement: Network card Aggregation (NIC teaming), and a brief introduction to some of the new Hyper-V options for data center design. Network card aggregation is also called load balance failover (load balancing Fail over ...)

Since 2006, when Google introduced the concept of cloud computing, as a new technology and business model, the concept of divergent views. Various agencies and experts in related fields have defined cloud computing from different perspectives, such as some from the application scenario, and some from the resource angle. Among them, the September 2009 U.S. National Institute of Standards and Technology (NIST) proposed the definition of cloud computing, is very representative, has been widely accepted by the industry: "Cloud computing is a convenient access to a shared pool of resources, on-demand computing resources (these resources include network ...).

TSV Stereo Stacking technology has been emerging in a variety of applications. TSV Stacking technology is used in DRAM, FPGA, wireless equipment and other applications, can enhance its performance and maintain low power consumption, thus gaining the favor of semiconductor plant and analog components factory, however, to accelerate the speed of TSV technology in the market, still need to rely on behalf of factories, IP vendors, 　　EDA plant and the plant to seal the work of cooperation. The previous article has analyzed how to apply the silicon perforation (TSV) to the stereo stacking of image sensors, power amplifiers and processors.
