investment by manufacturers in key network equipment, so that in a very short period of time, the emergence of a traditional second-layer switch, to the Advanced Layer-3 Switch, to the latest layer-4 or even layer-7 switch product.When a layer-4 switch differs from a

in the controllers Directory, which I do not want to see. In this way, the entire web layer has a DLL. So we need to configure it to a separate layer (in a separate project)Add an independent project, which is similar to the configuration in webconfig. It also supports multiple controllers. It depends on the application of your project. If necessa

The purpose of adding hardware services to the Android system is to enable app-tier apps to access hardware services through the Java interface. So how does app access the hardware services provided by the application frameworks layer through the Java interface? In this article, we'll add a built-in application to the Android

describe the presentation layer in the system architecture hierarchy to analyze the architecture and design mode of the presentation layer. Of course, we will analyze and explain the current popular presentation layer mode, mainly around the MVC model And analyzes the application design of the current MVC pattern in

The author of the enterprise is ready to use ibatis.net to do data access, so have this essay. In the example, for convenience, the data binding for the foreground takes the data source. Through this essay, can let have not contacted Ibatis.net and plan to learn it people have a quick understanding and start! First, we introduce the architecture of solution, which is divided into four projects: WEB: Foreground application; BLL: Business processing

It is very useful to know some basic router functions. Here we mainly analyze the practical application of the network layer in the basic router functions. Traditionally, a router operates on Layer 3 of the OSI Layer 7 Protocol. Its main task is to receive data packets from a network interface and decide to forward the

, can also manage distributed database transactions. We can go to see a friend Artech article: http://www.cnblogs.com/artech/archive/2012/01/05/custom-transaction-scope.html, They proposed a class similar to TransactionScope usage. However, the classes they present do not support distributed transactions for the time being. If it is non-distributed, it can be borrowed. Another thing to say is that the code Artech in this article proves a case of TransactionScope. When the insertion record to 100

Models very well. The service layer not only organizes business components, but also organizes application-specific services, workflows, and any other special components that appear in the business logic layer. It is controversial to use "service" as the name of the layer between the presentation

Article title: Network System Management-application layer packet capture solution and implementation. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 Introduction Packet capture needs generally come from filtering, conversion protocol, and packet capture analysis.

The layer-4 switch is quite common. So I studied the practical application of the layer-4 switch and shared it with you here. I hope it will be useful to you. With the increasing popularity of Mbit/s, Gbit/s, and even Mbit/s local area networks, broadband MAN networks and even broadband wide area networks are widely used. Whether it is Intranet, exclusive, or res

, also greatly stimulated the vast number of manufacturers in the network critical equipment, so that in a very short period of time from the traditional second-tier switches, to technologically advanced third-tier switches, and then to the recent launch of the fourth layer, or even the seventh layer of the product of the gratifying situation. Layer Fourth switc

　Introduction to the business logic layer The section of the thick black border of is the business logic layer, which can contain the following content: Application facade application appearance. This optional component provides a simple interface for the business logic component. Generally, multiple business oper

6.1 Overviewapplication-tier services are often used as diagnostic services. The application-tier service is used to perform functions in a client-server-based system (client-server Base system), such asdetection, inspection, monitoring, and diagnostics for in-vehicle servers (ECUs). The client usually refers to an external test device. The application-tier service sends a request for diagnostic functions

Summary No program can run without a user interface. Even if the middle-Layer Code is perfect, users cannot use it. Many architects do not pay much attention to the presentation layer. They only process the presentation layer as a detail after the business layer and data access lay
