Introduction To Network Protocols

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 ...

The Web spider enters a website, generally will visit a special text file Robots.txt, this file generally puts in the website server's root directory, like: Http://www.ithov.com/robots.txt. Site administrators can define which directory Web spiders are inaccessible through robots.txt, or which directories are inaccessible to certain web spiders. For example, some Web site executable directory and temporary file directory does not want to be searched by search engines, then webmasters can put these directories ...

Cloud storage is a concept that extends and develops in the concept of cloud computing (Cloud Computing). Its goal is to combine application software with storage devices to transform storage devices into storage services through application software. In short, cloud storage is not storage, it's a service. This service can provide virtual storage on demand on the network, also known as data storage as a service (Storage, DaaS). The customer pays for the storage capacity that is actually required to purchase. Any reference to the amount of fixed capacity added ...

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 ...

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 ...)

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 ...

The author learned from the Global IPV6 Summit forum that our country's independent research and development of domain name dedicated equipment has been the first global through the IPV6 Gold Core protocol to enhance the certification of commercial DNS equipment, but also China's first comprehensive support for DNSSEC commercial DNS equipment.　　This means that after years of IPV4 technology, in IPV6 Domain name technology Service level, China has stood in the world's leading position, for our country to build a IPv6 based on the next generation of trusted network to provide technical support and technical advantages. With the exhaustion of IPv4 address, take IPV6 as the core technology ...

Internet age, SNS marketing, microblogging marketing and Word-of-mouth marketing, and other emerging network marketing methods, but the earliest, most commonly used network marketing means-the status of mail marketing has not been shaken. e-mail to wake up the old customers two times to purchase, to achieve e-commerce two times marketing, has its unique advantages. 　　So how to improve the mail delivery rate and open rate, so that more customers see the seller sent the mail, let's look at the following. Only when the mail arrives at the customer's mailbox can it be seen and opened by the customer. And because of the junk mail ...
