CDN router mining machine
Micro mining machine is a kind of mining machine, which is a computer used to earn bitcoin. This kind of computer generally has professional mining crystal, and works in the way of burning graphics card, which consumes a lot of power. One of the ways to get bitcoin is that users download software from personal computers and then run specific algorithms to communicate with remote servers to get the corresponding bitcoin
functions of mining machine:
mining machine is one of the ways to obtain bitcoin Bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically
The decentralized feature and algorithm ofP2P can ensure that the currency cannot be manipulated by mass proction. Any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers

types of mining machine:
1. CDN mining machine
with the emergence of Xunlei game cloud, a new mining machine, called CDN mining machine, appeared. This miner, because it doesn't need too strong performance, is just a router or TV box. Thunderplay cloud uses a unique consensus mechanism, not by contributing computing power, but by contributing network bandwidth and storage space
2. FPGA miner
FPGA miner, it is a hardware base plate, equivalent to a piece of white paper, what kind of function you want to achieve, write what kind of program to it. Compared with ASIC, the chip designed for specific purpose is much more flexible
3. Cloud miner
cloud miner is relative to local mining, which can be compared with the relationship between network disk and local hard disk. In short, you can use other people's mining machines remotely through the network instead of mining machines. It can be said to be a cloud application or a rental hosting service

2. People who are connected to the Internet should not watch online videos, play online games, download files, etc., so as to avoid excessive consumption of network bandwidth resources, that is, to save money
3. Choose the router with better hardware performance, quality and manufacturing process, and at the same time, pay attention to the bad router system configuration, which will also affect the overall network speed.
The full name of CDN is content delivery network. CDN is a content distribution network built on the network, which relies on the edge servers deployed in various places. Through the load balancing, content distribution, scheling and other functional moles of the central platform, users can get the required content nearby, rece network congestion, and improve the response speed and hit rate of user access. The key technologies of CDN are content storage and distribution
extended data:
the functional entities in CDN network include content caching device, content switch, content router, CDN content management system, etc. Content caching is a CDN network node, which is located in the user access point. It is a content providing device for the end user. It can cache static web content and streaming media content, and realize the edge propagation and storage of content, so that users can access it nearby. The content switch is located in the user access center, which can balance the load of multiple content caching devices in a single point, balance the load of content caching and control the access to the content
CDN content distribution network. CDN is a content distribution network built on the network, which relies on the edge servers deployed in various places. Through the load balancing, content distribution, scheling and other functional moles of the central platform, users can get the required content nearby, rece network congestion, and improve the response speed and hit rate of user access
The basic principle ofCDN is to widely use various cache servers, and distribute these cache servers to the areas or networks where users visit relatively intensively. When users visit websites, the global load technology is used to direct users' access to the nearest normal cache server, and the cache server directly responds to users' requests
acceleration node is the node server deployed by CDN service providers all over the country. When users visit the website, they will visit from the nearest node server to improve the access speed
extended materials:
content distribution network (CDN) includes four elements: distributed storage, load balancing, network request redirection and content management. Content management and global network traffic management are the core of CDN. Based on the judgment of user proximity and server load, CDN ensures that the content serves the user's request in an extremely efficient way
generally speaking, content service is based on cache server, also known as proxy cache, which is located at the edge of the network and only & quot; away from users; One jump & quot; It's so far away. At the same time, the proxy cache is a transparent image of the content provider's source server (located in the CDN service provider's data center). This architecture enables CDN service providers to provide key technologies to end users on behalf of their customers, i.e. content providers:
1. Content publishing: it distributes or delivers content to the nearest remote service point (POP) with the help of indexing, caching, stream splitting, multicast and other technologies
2. Content routing: it is an integrated network load balancing technology. Through the redirection (DNS) mechanism in the content router, users' requests are balanced on multiple remote pops, so that users' requests can get the response from the nearest content source
3. Content exchange: according to the availability of content, the availability of server and the background of users, it uses the technologies of application layer exchange, stream splitting and redirection (ICP, WCCP) on the cache server of pop to intelligently balance the load and traffic
Performance management: it obtains the status information of network components through internal and external monitoring systems, and measures the end-to-end performance of content publishing (such as packet loss, delay, average bandwidth, start-up time, frame rate, etc.) to ensure that the network is in the best running state
