Linux Network embedded Devices

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

Pon Technology and FTTH

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

What is FTTH

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

Features and applications of emerging ADSL Access Technology

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. Optimized RS gain. The ADSL2/2 + frame generator improves the flexibility and programmability of constructing the RS code. Therefore, at low data rates, ADSL2/2 + can obtain higher encoding gain from the RS code. Improved the initial state machine. ADSL2/2 + has greatly im
