Wanbit mining machinery system

1. 1-mp3 (MPEG Audio Layer 3) is a kind of audio signal file with high compression rate. Although it has a high compression ratio of music signal, it can still be comparable with the sound quality of CD / MD. Mp3 up to 10 to 1 compression ratio. Make a CD-R / RW can hold 10 ordinary CDs of music. It can play music for a long time. You can get MP3 music from the Internet or other channels
2 - wma (Windows Media Audio) is developed by Microsoft. Audio compression technology to guide the display music. Its sound quality can be comparable with MP3, with high compression. Some songs are made into wma format, the size of music can reach one third of MP3! You can edit your favorite music into wma file by using Windows Media Player 7.0 or above<
comparison:
MPEG Audio Layer 3 (mp3) at 32-320kps (bit), sampling frequency of 32, 44.1, 48Khz
at 8-160kps (bit), sampling frequency of 16, 22.05, 24khz
Windows Media Audio (WMA) at 64-192kps (bit), sampling frequency of 32, 44.1, 48Khz

2. After four VLANs are delimited, different MAC is set in each Wan, which is no good. At the beginning, I set VLAN as
vlan0
4
5 *
corresponding LAN
original physics WAN port
vlan1
0
5
corresponding Wan
Original physics lan4 port
1
5
corresponding wan2
original physics lan3 port
2
5
corresponding wan3
original physics lan2 port
corresponding vlan4
3
corresponding wan4
original physics lan1 port
setting After that, I found that the above problem was e to the physical port. Later, I found that I switched the configuration of vlan2 and vlan3, and found that the adjacent ports could not dial successfully at the same time. So I guess it's not the physical port problem, maybe it's the VLAN
id problem
the switch chip of this route is adm6996. After checking the information, this chip supports 4-bit VLANs, that is, there are 16 VLANs from 0 to 15. Later, I tried VLAN
ID from 1 to 15 (it took me a long time), and finally got a result: VLAN
ID is the lowest one in 4 bits, So there are only 0 and 1 VLANs
for example, if one port is set to vlan5, the binary is 0101, and the other port is set to vlan11, the corresponding binary is 1011. If the first three bits of the two ports are removed, they are all 1, and the corresponding is vlan1, so there is a conflict
I don't know what causes this phenomenon, whether it is the register fault in adm6996 chip or the openwrt system bug????

3. 1.Java环境变量设置就不说 但是配置Maven需要检查下Java环境变量的设置需要检查JAVA_HOME环境变量以及Java命令
复制代码

wanyakundeMacBook-Pro:Library wanyakun$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home
wanyakundeMacBook-Pro:Library wanyakun$ java -version

复制代码

2.接着到http://maven.apache.org/download.html下载Maven安装文件，如apache-maven-3.2.3-bin.tar.gz，然后解压到本地目录

接下来，我们需要设置M2_HOME(IntelliJ默认为M2_HOME)环境变量指向apache-maven-3.2.3，并且把Maven安装目录下的bin/文件夹添加到系统环境变量PATH中去：

vim打开/etc/profile文件 加入如下代码：

export M2_HOME=/Users/wanyakun/Documents/apache-maven-3.2.3

export PATH=$PATH:$M2_HOME/bin

至此，安装完成，我们可以运行以下命令检查Maven安装：

Setting method:

log on the router, click the system in the left navigation - click the IP flow control option, where you can enter a section of IP address to limit the uplink and downlink bandwidth, and then click the Save button to save it

1. Click to list the IP speed in use

after clicking, you can view the current internal IP's external network uplink and downlink traffic and WAN port traffic, which can be arranged according to IP and speed, and effectively view the network situation

2. Start IP and end IP

this is to select the intranet IP segment or single IP you want to limit. If only a single IP is limited, just fill in: 192.168.1.100 to 100, then this rule is to control 192.168.1.100. If you want to limit a group of IP ranges, fill in 192.168.1.100 to 150, so this rule is to limit 192.168.1.100 to 150. If this bandwidth limit is for all IP in the intranet, fill in 192.168.1.0 to 0, which means that all IP are restricted by this rule

3. Uplink bandwidth www.2cto.com

refers to the upload bandwidth of Intranet IP

Fourth, downlink bandwidth refers to the download bandwidth of Intranet IP, where the rate is kbit / s, the general file download rate is KB / s, 1KB = 8kbit

v. flow control threshold value

this threshold value refers to the set threshold value of WAN port bandwidth. When flow control is enabled, if it is not set or set to 0, it means that flow control is always enabled. Otherwise, it means that when the total utilization rate of WAN port is greater than the threshold value, flow control will actually take effect. After the flow control takes effect, the system will execute the flow control for 5 minutes regardless of whether the flow reaches the threshold. After 5 minutes, the system will detect the WAN port utilization again. If it is lower than the threshold, the flow control will not be enabled. If it is higher than the threshold, the flow control will be enabled again

note: this function is only used when the maximum bandwidth is limited, and it needs to enable queue management and set WAN port bandwidth

6. Automatic load balancing

If multiple adsls of the same operator are used, automatic load balancing can be selected, and static routing table is not needed in WAN port configuration. Traffic will automatically use multiple Wan ports to transfer data, so that data can be evenly transmitted from multiple Wan ports

7. Line backup mode when this function is enabled, wan1 is used as the main line and other lines are not online. When wan1 is disconnected, other lines will go online. If wan1 goes online again, other lines will go offline again

8. Start queue management

when you choose to limit the minimum bandwidth, starting queue management will rece the system performance. If you need to ensure the minimum bandwidth, start queue management, accurately set the WAN port bandwidth, configure the uplink and downlink value of the minimum bandwidth, and then restart the device to achieve the maximum speed of each computer; www.2cto.com 9. Wan line speed setting is the same as WAN port configuration

X. flow control mode

(1) guarantee the minimum bandwidth

as the name suggests, guarantee the minimum bandwidth that each computer can use

(2) limit maximum bandwidth

to limit the maximum available bandwidth of this rule, that is, the maximum bandwidth will not exceed this set value

the above is the flow limit setting of Lingke router, I hope it can help you

5. 1B (byte) byte = 8bit
broadband sellers say 1mbit
1mbit = 1024kbit
so the actual download speed is 1024kbit = (1024 / 8) byte = 128KB
4m = 512KB

1MB maximum downlink speed is about 120KB
2MB 230kb
4MB 450kb


1KB = 8kbps

for example: 800kbps / 8 = 100kb

7. The characteristics of ISDN (1) the compatibility of various services. A pair of subscriber lines can be used to provide telephone, fax, videotex data communication and other services. If users need more high-speed information, they can use primary group user interface to connect PBX, videophone, videoconference or computer LAN. In addition, ISDN users can choose information rate and exchange mode according to their needs in each call 2) Digital transmission ISDN can provide end-to-end digital connection, that is, the channel between the terminal and the terminal has been completely digitized, with excellent transmission performance and fast information transmission speed 3) The key of ISDN to provide multiple services is to use standardized user interface. The interface has basic rate interface and primary group rate interface. The basic rate interface has two 64kbit / s information paths and one 16kbit / s signaling path, which is called 2B + D for short; Primary group interface has 30 64kbit / s information channels and one 64kbit / s signaling channel, 30b + D for short. Standardized interface can ensure the interoperability between terminals. A basic rate user interface of ISDN can connect up to 8 terminals, and use standardized socket, which is easy to access various terminals 4) It is convenient to use. Users can freely combine different types of terminals on a pair of subscriber lines according to their needs. For example, they can connect the telephone, fax machine and PC together, and they can make calls, send faxes or transmit data at the same time 5) Terminal mobility ISDN terminal can suspend the ongoing communication ring the communication process, and then resume the communication when necessary. This performance brings great convenience to the user. The user can move the terminal to another room after the communication is suspended, insert it into the socket, and then resume the communication. At the same time, you can also set the identity password to recover communication 6) Low cost ISDN is developed through the digitalization of telephone network, so only adding or changing some equipment in the existing communication network can form ISDN communication network. ISDN can integrate all kinds of services in one network to improve the utilization rate of communication network. In addition, ISDN saves the investment of subscriber line and can obtain greater economic benefits--

For LAN environment, in order to ensure that each computer can access the Internet smoothly, limiting the network speed of each computer is the best way. Today, I will take Lingke router as an example to introce how to limit the traffic

log in to Lingke router, click system in the left navigation - click IP flow control option, where you can enter a section of IP address to limit the uplink and downlink bandwidth, and then click Save to save it

1. Click to list the IP speed in use

after clicking, you can view the current internal IP's external network uplink and downlink traffic and WAN port traffic, which can be arranged according to IP and speed, and effectively view the network situation

If you want to limit a group of IP ranges, fill in 192.168.1.100 to 150, so this rule is to limit 192.168.1.100 to 150. If this bandwidth limit is for all IP in the intranet, fill in 192.168.1.0 to 0, which means that all IP are restricted by this rule

3. Uplink bandwidth www.2cto.com

refers to the upload bandwidth of Intranet IP

Fourth, downlink bandwidth refers to the download bandwidth of Intranet IP, where the rate is kbit / s, the general file download rate is KB / s, 1KB = 8kbit

After 5 minutes, the system will detect the WAN port utilization again. If it is lower than the threshold, the flow control will not be enabled. If it is higher than the threshold, the flow control will be enabled again

note: this function is only used when the maximum bandwidth is limited, and it needs to enable queue management and set WAN port bandwidth

6. Automatic load balancing

7. Line backup mode when this function is enabled, wan1 is used as the main line and other lines are not online. When wan1 is disconnected, other lines will go online. If wan1 goes online again, other lines will go offline again

8. Start queue management

when you choose to limit the minimum bandwidth, starting queue management will rece the system performance. If you need to ensure the minimum bandwidth, start queue management, accurately set the WAN port bandwidth, configure the uplink and downlink value of the minimum bandwidth, and then restart the device to achieve the maximum speed of each computer; www.2cto.com 9. Wan line speed setting is the same as WAN port configuration

X. flow control mode

(1) guarantee the minimum bandwidth

as the name suggests, guarantee the minimum bandwidth that each computer can use

(2) limit maximum bandwidth

to limit the maximum available bandwidth of this rule, that is, the maximum bandwidth will not exceed this set value

the above is the flow limit setting of Lingke router, I hope it can help you
