In the era of big data, IT vendors researching big data focused their research on optimizing the software architecture of big data systems, optimizing business logic, optimizing data analysis algorithms and optimizing node performance, while ignoring the evaluation of network links in the big data environment infrastructure And optimized. This article introduces Cisco's network architecture design and optimization experience in a Hadoop cluster environment. Big Data Hadoop Environment Network Features Hadoop cluster nodes through http: //www.aliyun.com/zixun/aggregation ...

In large data age, it vendors who study large data focus on optimizing large data system software architecture, optimizing business logic, optimizing data analysis algorithm, optimizing node performance, and ignoring the evaluation and optimization of network links in large Data environment infrastructure. 　　   　　This paper introduces the experience of Cisco Network Architecture design and optimization in Hadoop cluster environment. Large data Hadoop Environment network characteristics the nodes in the Hadoop cluster are connected through the network, and the following process in the MapReduce is in the net ...

What does Intel's takeover offer mean for the future of optical transceivers and copper companies? 　　Intel in the optical transceiver business slightly test depth, first, and then through the acquisition slowly back to the interconnection field. Intel is financing the high-speed interconnection network business that buys Cray. For the recent series of acquisitions on the large canvas added a heavy color-oclaro and Opnext merged; Sumitomo Electric Deviceinnovations American Inc. (sedu) buys Emcore parallel optical devices business. The acquisition is expected to be $140 million in June ...

In its purest form, the switching architecture is a network topology in which nodes connect to each other by deploying multiple, effectively linked switches. This is contrary to traditional broadcast media such as Ethernet, the traditional media has only one valid path, but http://www.aliyun.com/zixun/aggregation/14477.html ">ieee and IETF and other standard agencies are improving Ethernet, Add multiple valid paths and link state routing protocols instead of spanning trees to drive data ...

1 introduction In recent years with the development of global economic integration and the green trend of energy consumption, the global video conferencing market has witnessed a breakthrough growth. After nearly more than 10 years of wind, video conferencing technology and application has become increasingly mature, video conferencing has been the major institutions of enterprise Information System construction "standard." However, there is no shortage of complaints about the difference between the application effect and the expectation in existing customers. According to the survey, the definition, time delay, bandwidth, stability, high prices and so on are hindering the development of video conferencing industry is an important factor. In view of the above factors, people have ...

Over the past few decades, firewalls have been a port-based guardian of the Internet. 　　Now vendors are scrambling to roll out so-called "next-generation firewalls" because these "application-aware" firewalls can monitor and control access based on application usage. In addition, many firewalls have added more and more features to try to discover the 0 attacks, including intrusion prevention systems (IPS), web filtering, VPN, data loss protection, malware filtering, and even threat detection sandbox. For a separate IPs, because of its application control, it may be called "Next Generation IPs" ...
