Cloud computing power of router
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
extended data:
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
source of reference: network mining machinery
the switch is to solve the problem of mutual communication in the same network. With it, there is no need to worry about the advantages and disadvantages and switching mode of star network, ring network, pairwise interconnection network and other topologies. But it's still in a network after all
the router is different. What it wants to solve is to locate the communication target across the network through IP address, which is an essential tool for network interconnection
compared with distributed computing, cloud computing is not a concept at all. Cloud computing integrates resources and presents them to users in the form of services by means of distributed computing. For example, bird cloud provides cloud computing services to users through virtualization technology. Formally, it is given in the client server mode, but behind this server may be the integration of many physical computers, Including the integration using distributed computing.
Log in TP-LINK ID on the cloud router, and the mobile phone can manage it by logging in TP-LINK ID with app
mobile phone management router needs to use mobile phone app. Please download the management app of TP-LINK cloud router on your mobile phone:
Step 1. If you log in TP-LINK ID on the router
to remotely manage the router, you must log in TP-LINK ID on the cloud router. If you have created a TP-LINK ID, please enter the ID number and password to log in directly. You can also create a free TP-LINK ID as follows:
number of slots available to users
this indicator refers to the number of slots that users can use in molar routers, except for CPU board, clock board and other necessary system boards and / or special slots for system boards. According to the index and the port density of the subscriber board, the maximum number of ports supported by the router can be calculated<
CPU
CPU is the heart of router no matter in middle and low end router or high end router. Usually in the middle and low end routers, CPU is responsible for exchanging routing information, routing table lookup and forwarding packets. In the above routers, the capacity of CPU directly affects the throughput (routing table lookup time) and routing computing capacity (network routing convergence time). In high-end routers, packet forwarding and table lookup are usually performed by ASIC chip, while CPU only implements routing protocol, calculates routing and distributes routing table. Due to the development of technology, many jobs in router can be realized by hardware (special chip). CPU performance does not fully reflect router performance. Router performance is represented by throughput, delay and routing computing power
memory
the router may contain a variety of memories, such as flash, DRAM, etc. Memory is used to store configuration, router operating system, routing protocol software, etc. In middle and low end routers, routing tables may be stored in memory. Generally speaking, the larger the router memory, the better (regardless of the price). However, similar to CPU power, memory does not directly reflect router performance and capability. Because efficient algorithm and excellent software may greatly save memory
port density
this indicator reflects the integration degree of router manufacturing. Due to the different sizes of routers, this index should be equivalent to the number of ports per inch in the rack. However, for the sake of intuition and convenience, the maximum number of each port supported by the router can be used instead<
routing information protocol (RIP)
Rip is a distance vector based routing protocol, which usually uses hops as the measurement standard. Rip is an internal gateway protocol. Rip is the most widely used routing protocol because of its simple implementation. This protocol converges slowly and is generally used in small-scale networks. Rip protocol is stipulated in RFC 1058
policy routing mode
in addition to the destination address as the basis for routing, the router can also select the path for the packet according to the TOS field, source and destination port number (high level application protocol). Policy routing can achieve traffic engineering to a certain extent, so that different quality of service flows or different nature of data (voice, FTP) take different paths<
distance vector multicast routing protocol (DVMRP)
DVMRP is a distance vector based multicast routing protocol, which is basically developed based on rip. DVMRP uses IGMP to switch routing with neighbors
full plex line speed forwarding capability
the most basic and important function of router is packet forwarding. Forwarding small packets at the same port rate is the biggest test of router packet forwarding ability. Full plex line speed forwarding capability refers to the minimum packet length (64 bytes for Ethernet and 40 bytes for POS port) and minimum packet interval (in accordance with the protocol) for bidirectional transmission on the router port without packet loss. This index is an important index of router performance
device throughput
refers to the packet forwarding capability of the whole device, which is an important indicator of device performance. The router's job is to route according to IP packet header or MPLS label, so the performance index is the number of forwarding packets per second. Device throughput is usually less than the sum of all port throughput of router
port throughput
port throughput refers to the packet forwarding capability of a port, which is usually measured by PPS: packets per second. It is the packet forwarding capability of a router on a certain port. Two interfaces with the same rate are usually used for testing. However, the test interface may be related to the location and relationship of the interface. For example, the throughput between ports on the same card may be different from that on different cards
routing table capability
routers usually rely on the established and maintained routing table to decide how to forward. Routing table capacity refers to the limit of the number of routing table entries in a routing table. Because the router executing BGP protocol on the internet usually has hundreds of thousands of routing table entries, this project is also an important embodiment of the router's ability
backplane capability
backplane capability is the internal implementation of router. The backplane capability can be reflected in the router throughput: the backplane capability is usually greater than the value calculated according to the throughput and the test range. However, the backplane capability can only be reflected in the design, and generally can not be tested<
QoS classification
refers to the information on which routers can distinguish QoS. The simplest QoS classification can be port based. Similarly, the router can distinguish packet priority according to link layer priority (specified in 802.1Q) and upper layer content (TOS field, source address, destination address, source port, destination port and other information).
first, the cloud of ASUS router means that you can upload anything to their server. Or the hard disk you plug into the router's USB
some of the clouds in the second and third poles are mobile phone management plug-ins. Not much
at present, the cloud on the market does not have much function, so you can ignore it
in fact, ordinary routers can also realize remote management through VPN or peanut shell, which I have used before.
cloud routing is based on the intelligent router, relying on the functions of cloud computing and cloud storage to make it more optimized and convenient. The biggest feature is to save time, energy and cost. The biggest advantage is to fulfill your "private customization" dream. For example, when you have a lot of friends at home, you can set up your own router so that you don't need to expose your wireless password, and you can let your friends' mobile phones automatically connect to WiFi,
