It's not something new, and the wireless router has been using it a long time ago, but it has only recently begun to understand its rationale. Now the network embedded device's function is more and more powerful, each chip manufacturer's solution method supports this kind of complexity. Recently the company internship, to do a home gateway project. The following should not be counted as leaks, write a little more casually.
1. A Network chip architecture
You should be able to see that this
Often meet someone in the QQ group to ask about the product of Huawei's specific model number of the meaning of today's summary of the content to be posted for your reference.
LI (Lite software Image) indicates that the device is a weak feature version.

operators use FTTP to occupy the access and user station network market, and then provide the basic business operators with public access platform; Third, the government or equipment manufacturers to promote commercial testing, such as the Wuhan Long FEI apartment FTTH pilot achieved 158 of "three nets in one", Among them, 110 of them use Pon mode access, 48 use point-to-point MC access, but also plans to further expand the scale of the test; four is the FTTH test and local business, such as th
FTTH in Japan can be divided into three kinds of high-speed data, high speed data + voice and high speed data + Voice + video (Tripleplay), which embodies the trend of FTTH business development--three nets in unity. In terms of technology choices, Japan has renounced the early adoption of the MC approach and has shifted vigorously to the use of PON, especially Apon and Epon technologies.
South Korea, which is very popular in ADSL/VDSL, announced in
The choice of Internet mode. The Master of Windows optimization can automatically set the maximum transmission unit size, the maximum data segment size within the transmission unit, and the transfer unit buffer size according to the user's online approach.

Database Backup is very important. If regular backup is performed, the data can be restored to the last normal state in the case of a system crash, minimizing the loss. 1. run the mysqldump command to back up MySQLl. we can use it to back up data. the following assumes that we want to back up the tm database: # mysqldump-uroot-ptm gt; tm_050519. SQL enter the password as prompted, which makes it very important to back up all the databases in the tm d
frame overhead of the next-generation ADSL access technology can be programmed between 432kb/s, so that the overhead can be set to 4kb/s for low-speed data services, let more bits be used for the transmission of the Net Load.

LINUX driver learning: How to Solve Deviceorresourcebusy when loading a module-Linux general technology-Linux programming and kernel information. For more information, see the following. After the globalmem driver module is compiled, the following error message is displayed when the module is loaded through insmod:

Insmod: error inserting 'globalmem. ko':-1 Device or resource busy
