Does the delay of mine pool have anything to do with broadband

1. Gold, of course! This is the natural currency and the wealth of preserving value, with physical gold as the final guarantee; bitcoin is a virtual electronic currency, most sovereign countries do not recognize its legal status, because its main purpose is to decentralize and supervise, which is easy to become a disaster area of money laundering. In the field of investment speculation, when bitcoin is hot, it is more fierce than gold speculation. Provided by Liu Anyuan, an expert in stock analysis of Xinrong Street

2. Theoretically, the larger the bandwidth, the higher the priority in the network topology, and the faster the corresponding response speed. For users and ISPs, the higher the bandwidth, the more data transmitted per second, and the smaller the delay. But the delay level is determined by many factors. Every server (router) on the network is a node, and the response speed of all nodes together is its own network delay. If an intermediate node fails to provide service, other nodes will recalculate the route, but there will be a timeout timer before recalculating the route, Only when the response time of the destination node exceeds the timer, the routing calculation will be performed again. There is also the influence of DNS server and so on
cannot be confused. ISP can only guarantee the user's access network bandwidth and network delay, but can't guarantee the service with other nodes.

3. Network speed is the speed that your computer should access the telecom room through the network cable

network delay is the asynchronous time when your computer accesses the telecom room

the speed of opening a web page depends on the speed of the network, the delay, the size of the web page, whether to open the web page for the first time, and whether to visit the web pages of different network operators in the end. The details are as follows:
1. The speed of Internet is definitely the decisive factor for the speed of opening web pages. However, it is no problem for all operators to set up the speed of our consumers to visit web pages
2. The reason for delay is that if the concurrency exceeds the network load at the same time, there will be delay, which is the effect of asynchronous When I do the project in the Unicom computer room, I use Unicom's network cable to download. The speed is 5m-6m, and the delay is only 5-6ms)
3. The size of a web page mainly depends on whether the web page you visit is mainly pictures or text. In order to improve the access speed, the computer will automatically download all the pictures of the website, so that the second visit can improve the access speed. You don't have to load it
4. As the saying goes, the farthest distance in the world is the distance between China Telecom and China Unicom. Due to the competition between the two giant operators, if your broadband is Telecom, you will be very slow to visit the website of Unicom broadband. If your broadband is Unicom, it will be very slow to visit the telecom website. The most popular example: Tencent's crossing the line of fire. Do you know why there is a telecommunication zone and Unicom zone? That's why
therefore, the speed of opening web pages is determined by many factors

first of all, you go to the Internet to find out what Mbps means. This unit is to be converted. In fact, 1m bandwidth means 1Mbps. It's absolutely impossible for you to say 80mbps. I don't have this speed when I download in Unicom's computer room. 80mbps is equivalent to the current 80m broadband
in fact, 80mbps means that the maximum speed of your network card is 80mb (80mbps). This speed is much higher than the existing broadband speed, and this speed does not need to be considered

when pinging different websites, the delay is definitely different. Personally, I don't think there is a direct reason for this, which is related to what the staff of network operators said about the long network cable. This is mainly about concurrency. For example, your Ping is actually a request for the network. Your request will go through your network cable, to the last big optical cable, and finally to the server of the web page you requested. If you are not sending the request alone, there are many people sending the request at the same time, the server will receive many people's requests, which causes delay. Ping does not depend on the web page, but on the server on which the web page is deployed. It also depends on the bandwidth of the server

bandwidth and Internet are used to connect your computer or server.

4. The relationship between network delay and network speed is that the smaller the network delay, the better the network speed
relationship between network delay and network speed:
1 network speed refers to the time when the server responds to your connection request or exchanges the data you send, that is, the network delay or Ping value, with the unit of Ms. many users equate the network speed with the download speed, which is also incorrect
2. The size of Ping value indicates the speed of data exchange between client and server. The smaller the Ping value, the better the network speed. Generally speaking, the larger the bandwidth is, the smaller the Ping value will be. However, the actual situation depends on the connection and routing of network lines. It is not surprising that the opposite situation occurs
3. The time that a packet passes through one or more network segments is called delay. From the user's point of view, delay is the time from the user sending a request to receiving a response from the remote application system. Based on TCP / IP protocol, network transmission includes the following processes: router processing, user data unit transmission on the network and server processing, which will proce routing delay and user data unit transmission delay on the network. Routing delay includes domain name request delay, TCP connection establishment and release delay and IP routing delay. From the perspective of testing, delay is divided into one-way delay and two-way delay.

5.

Theoretically, the larger the bandwidth, the higher the priority in the network topology, and the faster the corresponding response speed. For users and ISPs, the higher the bandwidth, the more data transmitted per second, and the smaller the delay

but the delay level is determined by many factors. Every server (router) on the network is a node, and the response speed of all nodes together is their own network delay. If an intermediate node has problems, it cannot provide services

other nodes will recalculate the route, but there will be a timeout timer before recalculating the route. Only when the response time of the destination node exceeds the timer, the route will be recalculated. There is also the influence of DNS server and so on

cannot be confused. ISP can only guarantee the user's access network bandwidth and network delay, but can't guarantee the service with other nodes

solutions to high delay:

first ask the network company if there is any problem, if not, it's your problem. There are several solutions

1: Unplug all the wires of the router, including the wires, plug them back later, or press the restart button of the router, if you don't know, unplug them directly, The button is usually next to the power supply slot

BitDefender, Kaspersky, NOD32, and other world-famous killing softwares for overall antivirus

6. There are many reasons for this phenomenon. The following aspects are also the root of this phenomenon. You may as well check it carefully and thoroughly according to the following aspects; Your problem will be solved. Copyright statement: the answer is harmonious original, no one can embezzle! 1: check the power supply (after the transformation of the national two networks, including the remote mountainous area, the voltage of 99.98 is qualified, and there is no low voltage power supply; Low voltage is caused by the user wire diameter is too small, it is OK to replace the home wire) 1.1 use a multimeter to check whether the power supply is stable? 1.2 is the AC voltage fluctuation within the allowable range? Is the ripple coefficient of 1.3a/d power supply (checked by millivoltmeter) qualified? 1.4 is the temperature rise of the power supply abnormal? 1.5 whether the voltage stabilizing characteristics meet the technical specifications? 1.6 whether the voltage stabilizing characteristics and ripple coefficient under rated load meet the technical specifications? 1.7 when replacing a large fan, does your power capacity meet the requirements? 1.8 the power supply of general auxiliary equipment (router, network switch, cat, etc.) is rectifier power supply, which has no voltage stabilizing function. The ripple coefficient is large (which may be caused by dry filter capacitor), and the load capacity is poor; Special attention should be paid. 1.9 e to the over-voltage of the equipment (like feeding a child, too much can last), low voltage (like feeding a child, too little will lead to malnutrition), large voltage fluctuation (like feeding a child, too much to eat, too much to eat), over-current and heating, the overheating protection action will be switched out of fault and the equipment will be out of operation (that is, slow, delayed Repeat start, delay, drop line, interrupt, break line, automatic shutdown, crash, etc; 1.10 whether the over-current protection and over heat protection of power supply operate correctly? Is the movement sensitive? Do you refuse to operate or misoperate? 2: Check the network cable and crystal head (R45): 2.1 whether the crystal head and seat are inserted (loose)? 2.2 is the contact good? What is the contact resistance? 2.3 is there any ash deposit? Is it oxidized? 2.4 is the mechanical locking between crystal head and base locked? 2.5 is the locking firm? 2.6 is the network cable tightly pressed and in good contact with the crystal head? 2.7 the line to line insulation resistance of network lines (using a 100V megger) shall be greater than 20 megohm. Copyright statement: the answer is harmonious original, no one can embezzle! 3: lightning protection, grounding: grounding is mainly to protect the safety of people and equipment! Lightning will burn the network card; When serious, it can cause fire and casualties! Multi point grounding, repeated grounding and nearby grounding are the principles; Grounding is divided into protective grounding, shielding grounding and working grounding; Static electricity is the main cause of blue screen crash! I use a noise meter to test that the noise voltage is more than 6000 times of the signal when it is not grounded. If you are not grounded, can your equipment work with such a high noise? Grounding is the most basic requirement for it, especially for analog devices and digital circuits. Interference from all aspects can be eliminated or eliminated through grounding. External interference and coupling between local and local wiring can be eliminated and eliminated. Equipment grounding and shielding work should be done well. Many interference comes from poor shielding and poor grounding, Many people only work on the software, and many interferences are caused by poor grounding or no grounding. This kind of fault is very easy to occur and easily ignored by many people. Many equipment damage is directly related to grounding. No grounding or poor grounding will lead to inter symbol interference, bit error, delay, packet loss, interruption, disconnection (disconnection, interruption), crash, card Automatic shutdown, repeated startup, repeated startup, frequent restart (or repeated connection) and other phenomena. There must be more than two grounding electrodes for grounding, and the interval between each grounding electrode shall be at least 10 meters. The grounding wire from the grounding electrode to the machine room shall not have any joint. Soft copper wire with a cross section of not less than 25 square mm shall be introced into the bus bar of the machine room (no joint is allowed in the middle), and the grounding wire shall be symmetrically connected with the Faraday network to facilitate the diversion of current, The connection point with the bus bar shall be coated with silver powder conctive paste, the cross section of the grounding wire from each equipment to the bus bar (independent) shall not be less than 4 square meters of multi strand soft copper wire, and the grounding resistance of the bus bar to each grounding electrode shall be less than 5 ohm (the smaller the better). At least twice a year, the grounding instrument (more than 2.5 level grounding instrument measurement, and the instrument is within the inspection period) shall be used for inspection. When checking the grounding electrode, it is strictly forbidden to do it in thunderstorm weather. It is strictly forbidden to use the n-zero line of water pipe and power line as grounding; That is, independent grounding device. The line of each equipment shall be connected to the bus bar of the machine room independently. It is strictly forbidden to connect the bus bar in series. I can say subjectively: whether you are an indivial user or a collective user of a large computer room, you are not grounded at all. Copyright statement: the answer is harmonious original, no one can embezzle! 4: Bandwidth: the bandwidth from operators to users is very important. Without enough bandwidth, enough data traffic cannot be guaranteed; It is impossible for computers to get on the Internet smoothly; The bandwidth mentioned above refers to the bandwidth of the whole process. Like on the expressway, there is such a wide bandwidth that there can be no fluctuation in the whole process; A little fluctuation in the whole process will affect the network speed; The user has the right to ask the operator (test with sweeper) for protection; 5: Signal to noise ratio (signal to noise ratio, which can be understood as signal purity) is small, the useful signal is covered by the noisy spurious signal (especially the inter symbol interference), so that the way to receive the signal can not correctly extract the useful signal from the noisy signal, and the judgment circuit can not correctly judge the code element, which will lead to error code Serious bit error is packet loss, serious packet loss is the cause of delay, and serious delay is line dropping (slow, delay, repeated start, line dropping, delay, line dropping, interruption, line breaking, automatic shutdown, crash, etc.). Use a noise meter or level meter to measure whether the noise level is within the allowable range, Or use oscilloscope to observe whether there is stray signal? Is there inter symbol interference? Take measures to eliminate it. The signal to clutter ratio should be more than 60dB. Test (observe) with sweep frequency instrument and oscilloscope. This indicator is to ensure that the road is smooth and barrier free. There is such a wide road, but also the whole process barrier free. 6: Matching: matching includes level matching and impedance matching (test with level meter and signal generator). 6.1 level matching: the received signal should not be too low. When it is too low, it can not reach the threshold level required by the receiving Road, and the equipment can not work normally; If the level is too high, the front-end circuit will be saturated or burned out. If the receiving level fluctuates near the receiving threshold, the computer will restart frequently; Therefore, receiving level adjustment is very important. Use level meter or oscilloscope frequently in operation to monitor and adjust the receiving level at the connection within the appropriate range. According to the instruction, monitor the adjustment with a level meter. 6.2: impedance matching: the connection point must match the impedance relatively. If the input and output impedance do not match, it will lead to reflection attenuation, and no matter how strong the signal is, it will not work normally. 7: Optimize the network structure, people turn on the computer to access the Internet will proce garbage, just like eating, not cleaning the table, not washing the dishes, not cleaning the stove will proce computer garbage, the computer will graally show slow, card, delay, repeated start, offline and other failures; Therefore, I recommend using some small tools: such as super rabbit, optimization master, Lu master or 360, etc; Develop a good habit of cleaning up rubbish before going offline. 7.1: timely removal of garbage fragments and ie cache generated by the Internet: as long as you use the computer, garbage will be generated. If you don't clean it in time, it will accumulate more and more. If you don't clean it for a long time, it will make the running space of C disk smaller and smaller and disorderly. Finally, it will slow down graally until it crashes; Therefore, regular sorting and running C disk can keep the computer running speed. 7.2: synchronize the ADSL device first: power off the device and restart it. 8: Software settings and configuration 8.1: common software download software to the official website as far as possible, do not install 3, informal software does not install, P2P (occupy resources) software does not install, not commonly used software does not install. Turn off all unnecessary network connections and startup items, such as Thunderbolt, BT, donkey, etc; Do not put the non running software in the running C disk; Update patches in real time. Game software should be downloaded from regular large websites. Pay attention to whether the software is stable. Immature and unstable software will lead to slow, card, crash and other failures, especially some popular game software. Some netizens have a strong response to this. Such software should be paid special attention to or deleted immediately; When downloading software, we should pay attention to the rogue software inserted into the critical computer security, at any time to clear. Some game software started, the game will be directly t off, after the unlimited drop, restart and other failures. Protocol: the protocol in the network should also match it, and mismatching will also cause some equipment failures. Software conflicts will also cause delay, card, slow, crash, offline, interruption and other issues. 8.2: antivirus software and firewall at least one valid genuine antivirus software, and often upgrade the virus library: proper firewall settings (not too much, too high, too low), will cause some web pages can not be opened; Virus can make the computer slow down, crash, drop line, card, repeat start and switch failure. 9: Temperature, humidity and temperature rise (the temperature is graally rising after power on) with the extension of power on time, the temperature of the main equipment and its auxiliary equipment (cat, router, network switch, etc.) will graally rise. If it can not be sent out quickly, it will change from delay - slow - line drop - crash. 9.1: humidity: in rainy season or rainy days and areas with high humidity, the insulation between lines and devices is reced, and the signal level drops, resulting in inter symbol interference, bit error, delay, packet loss, interruption, disconnection (short line or interruption), crash, automatic shutdown, repeated startup (repeated connection), or unstable operation of the computer. Humidity accelerated oxidation, resulting in transmission interruption. 9.2: temperature (recently, with the graal increase of temperature, the faults caused by temperature will graally increase): from the start of the machine, the temperature will graally increase. When the temperature rises to a certain value, it will be stable at this value, and the difference between this value and the ambient temperature should not be greater than 25 degrees; As the computer is a semiconctor device, the actual temperature of the device should not be higher than 85 ℃; When the chip temperature is close to 80 degrees, measures should be taken to rece the working environment temperature of cat, router, network switch and computer equipment. If beyond this range, the computer will proce inter symbol interference, error code, delay, packet loss, intermittent, offline (disconnection or interruption), crash, automatic shutdown, repeated startup (frequent connection) and other phenomena. 9.3: the temperature rise (the difference between the actual temperature of the equipment and the ambient temperature is called the temperature rise) is less than 25 ℃. The temperature has a great impact on the normal operation of the equipment, especially when the network switch, router, computer motherboard chip and network card have a large isothermal rise, the equipment will not work; In particular, the portable computer (also known as notebook) is difficult to dissipate heat e to the priority of volume in design, which is most likely to cause inter symbol interference, bit error and delay caused by temperature rise

7.

The delay is also related to your line. The quality of the cat, the quality of the line and the operation mode of the cat have a lot to do with the delay and the network speed. If you want low delay, the cat's best operation mode is fast + G.dmt, because the delay of interleaving mode + ADSL2 + mode will be much higher, but it is stable, and the Telecom is the default interleaving mode, which needs to be modified manually, This depends on your cat and the quality of the line and choose the corresponding working mode. Generally, the delay of G.dmt is lower than that of ADSL2 +... And the attenuation of the cat also has a great impact on the delay...

8. Network bandwidth: refers to the speed of the connection (for example: 10M / s), the larger the bandwidth, the faster the speed.

delay and packet loss rate: basically have nothing to do with the network bandwidth, they are used to indicate the state stability and instability of the network; The packet loss rate refers to the ratio of lost packets / received packets. The smaller the two values, the better

I hope I can understand it from the perspective of personal understanding!
