4.3.2 Working Principle of pppoe ProtocolThe pppoe protocol workflow consists of two phases: discovery and session. The discovery phase is stateless to obtain the Ethernet MAC address of the pppoe end (on the local ADSL device, and create a unique pppoesession_id. After the discovery stage ends, it enters the standard PPP session stage. When a host wants to start

Personal email:Xiaokeweng@gmail.com The basic service that satisfies the pppoe connection is to ensure that the ppp protocol can be encapsulated in the Ethernet framework. Because the ppp protocol is integrated, therefore, it is achieved that VPC cannot provide authentication, encryption, and compression functions. Essentially, it is a ppp protocol tunnel that allows two Ethernet interfaces in the Ethernet broadcast domain to be created. It uses tradi

The five principles of OO refer to SRP, OCP, LSP, DIP, ISP.Open Closed Principle is the most basic design principle in the Java world, which guides how we build a stable and flexible system.Defined:A software entity such as classes, modules, and functions should be open to extensions and closed for modification.Softeware entities like classes,modules and functions should is open for extension but closed for modifications.The opening and closing principle means that a software entity should be ex

Interface isolation principle (ISP): it is better to use multiple special interfaces than to use a single total interface. The dependence of a class on another class should be based on the smallest interface. An interface represents a role, and different roles should not be assigned to an interface. Unrelated interfaces are merged to form a bloated large interface, which is a pollution to roles and interfaces. Synthesis/aggregation Reuse Principle (C

I asked everyone to test 1.5 last time. After four days, I had a good news. Now, I have handled some problems in the use of 1.89 in 1.5, which further ensured that the blacklist is free. It can be said that after five days of testing, the tool without blacklisting has been fully successful, and the software can run on the Internet starting from 1.89. In this way, no special computer is needed to run the tool. The new Wan Port Extension tool allows users to easily implement VLAN connection and

Unless you use Telnet to the software logon ISP's server, you are not able to connect the database via DSN. Here are a few ways to connect you beyond your ISP and make it easy to connect to your database: 1.SQL Server CStr = "PROVIDER=SQLOLEDB; Server=CStr = CStr "network=dbmssocn;uid=Set conn = Server.CreateObject ("Adodb.connection") Conn.Open CStr ' Connect with NETWORK=DBMSSOCN to avoid errors caused by admin naming %> 2.Oracle CStr = "provider=o

Before formally starting this article, let's review some basic ideas and methods of CFA image denoising. Then I will be in detail with you to share their learning understanding of the BM3D algorithm, operation process, its advantages and disadvantages, the final will give the algorithm for reference.In the ISP module, the researchers will discuss whether the Denoising module (Noise Reduction) is either before or after the Mosaic module (DEMOSAIC).

ISP QoS LabIn ISP QoS Lab1-PQ Priority Queue (PQ, Priority Queue), four queues are high, medium, normal, and low Priority. Data packets are placed in different queues according to prior definitions. routers provide services in high, medium, normal, and low order. Only a queue with a high priority is empty before serving as a queue with a medium priority, and so on. This ensures that high-priority data packe

According to a message from seekingapha, ANBA is expected to launch a 14nm ISP chip next year.Fermi Wang-president and CEO said:First, 14nm is still an important direction for our R D this year. This is necessary because we believe that when we implement the 14nm product process on the next generation of camera products, this will help improve our performance, while opening gaps with competitors in terms of power consumption and Video performance.At

PPPoE Overview PPPoEPoint-to-Point Protocol over Ethernet), that is, the Point-to-Point Protocol on Ethernet, which enables a host on the Ethernet to connect to the Internet through a simple access device, and control and manage the connected users. PPPoE uses Client/Server). It encapsulates PPP packets in Ethernet frames to provide point-to-point connections over Ethernet.

The Konqueror browser is integrated in qtopia2.2 to enable mini2440 Internet browsing.But qtopia2.2 does not seem to provide the ADSL dial-up function, so I decided to port it myself to implement ADSL dial-up Internet access.My ADSL cat is a cat with a wireless route provided by China Telecom.
