Protocols In Data Communication

The following article is mainly about wireless encryption is commonly used in wireless network encryption protocol, in the actual operation of the widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol two. The widely used wireless network encryption protocol mainly includes WEP encryption protocol and WPA encryption protocol. WEP protocol is also called Wired Equivalent encryption protocol, this kind of wireless communication protocol is often those who are eager to produce and sell wireless equipment in a relatively short period of time to put together the informal wireless encryption communication standards, from the current view of this wireless network encryption protocol There are quite a lot of security ...

Hadoop RPC communication is different from other systems RPC communication, the author for the use of Hadoop features, specifically designed a set of RPC framework, the framework of personal feeling is still a little complicated. So I'm going to split into client-side and Server service-side 2 modules for analysis. If you have a good understanding of RPC's entire process, you must be able to understand it very quickly for Hadoop RPC. OK, let's cut to the chase. The related code for the RPC of Hadoop is ORG.APAC ...

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 ...

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 ...

With the increasing of data center processing ability, the data center also put forward higher request to its network equipment communication ability. According to the evaluation of Market Research Institute Infonetics, the data center Ethernet market will usher in a full development momentum, and the current data center Ethernet network is in the 10Gbps to 25Gbps or even 50Gbps Exchange interface standard large-scale upgrade phase. Therefore, the Data Center network architecture, operation and management, virtualization and other related aspects will be adjusted accordingly, so the current problems in the data center network are ...
