The Internet bandwidth problem is already the main bottleneck affecting Internet development, in many webmasters, many webmasters asked this question: "What is the difference between dual-line Single IP address and dual-line Dual IP address? What is the difference between single-line and dual-line IP addresses?
A. Dual-line dual-IP Advantages and Disadvantages: Dual-line dual-IP is characterized by fast speed and good North-South communication. It is not very mature in technology and unstable.

I. Overview:
It is estimated that the actual work will often encounter with Asa two ISP line, for example, Telecom and Netcom, and there is not enough budget to buy load balancing equipment, but want to achieve link load sharing and automatic switching, from telecommunications to traffic, from the telecommunications line back, from Netcom to the flow of traffic from the
"Practical!" What about broadband connection errors? "Broadband connection errors often pop up 691, 623, 678, 645, 720, 721, 718, 734, 769, 619, 676, 815, and so on the number of Windows, what do you know? What are you going to do about this? ? This is very practical, oh, the posture again!
Processing process for broadband connection error 691 (Access denied due to invalid user name or password on domain):
Step one: Check the user name password to fill in the error, if the user account passwor
from the experience of porting Z5S 4.4 kernel and the official 4.4 audio configuration file, we should not add any Nubia features (of course, the headset detection must have been added ), however, the Nubia mentioned here is nothing more than the Z5Sn es325 audio conditioning chip, which has no effect on z5s. in the previous official audio configuration file snd_soc_msm_Taiko 4.2, you can find es325 configurations. the z5s 4.4 kernel I transplanted e
stillIn non-mobile devices (such as PCs), the audio frequency is usually produced by a crystal oscillator, but in the design of smart phones, to avoid additional power consumption, board space, and frequency chip costs, the designer prefers to separate the frequency functions required by the HIFI audio from the existing frequency. Because the low power consumption and low noise lock loop (PLL) can be integrated into the hybrid signal chip at a relatively low cost, so today's chip manufacturers
Integrated smart phones must have PCM interfaces and independent I2S or ac'' 97 interfaces at the same time.

Chapter 3rd DNS for setting up domain names
We'll warm up before the play starts.
Intelligent DNS can be said to be the basis of CDN. Believe that everyone do the site will have the following situation: Home page two links, telecommunications users please visit the main site A, Netcom users please visit the Mirror site B. Then do two domain names, www.naizhao.com point to a,cnc.naizhao.com point B. The user looked at half a day feel dizzy, casually p

First, register the aggreger in oncreate,
registerReceiver(headSetReceiver, new IntentFilter(Intent.ACTION_HEADSET_PLUG));
Next, it is the receiving broadcast part:

These days we have dramatically modified our ALSA audio driver and have a deeper understanding of the importance of mechanism and policy separation.
To put it bluntly, Linux device drivers has gone through countless times, but ignores one sentence in the Introduction: differentiation mechanisms and policies are one of the best ideas behind UNIX design.
"What features are required" is a mechanism, and "how to use these features" is a policy. More than a year ago, when I first took over audio driv
To connect to other mobile phones through Bluetooth, follow these steps:1. Click application on the standby page ].2. Click set ].3. Click [Bluetooth] and then click the slider below it. Green indicates that it is enabled.4. When this feature is enabled, the tablet automatically scans available devices and selects the device to be paired. Here, we use Galaxy J3 as an example. (Note: Make sure that the pairing device has Bluetooth enabled and is visible .)5. A Bluetooth pairing request will pop u

IPhone7 How to charge while listening to music? 3 Ways to solve
Method One: Purchase Airpods wireless Headset
Airpods Wireless Headset Function We have this like advanced Bluetooth headset, one charge can be used for 5 hours, easy to achieve side charge, while using Airpods wireless headset listening to music.
Broadband access networks are currently the most commonly used access technology. However, we still have many problems that need to be solved and considered in order to better serve users. Designers must also design reasonable and optimized implementation solutions, meet various user needs. In the boom in broadband network construction in China, Shida network has established close cooperation with major telecom operators such as China Telecom, China Netcom
There are two separate broadband lines in the home, one of which is China Telecom, the other of which is China Netcom, and the other of which has two NICs and two Modem. to make full use of both the two broadband lines, we can ensure that the address access speed of China Netcom and China Telecom lines is relatively fast.
We want to merge the two lines and access the China Telecom Network through the China
Chapter 2 set the DNS of a domain name
Let's warm up first before the beginning.Intelligent DNS is the foundation of CDN. I believe that there will always be two links on the home page. For telecom users, visit Main Site A and for Netcom users, visit image site B. Then there are two domain names. www.naizhao.com points to A and cnc.naizhao.com points to B. After reading it for a long time, the user felt dizzy and casually clicked it in. He found that
