What does front-end machine mean?

Front-end machine refers to the intermediate equipment used on site. The front-end computer generally exists between the front-end client and the back-end server, playing the role of an adapter, that is, converting between different communication protocols, data formats or languages. Banks generally use front-end machines for systems such as ATM, POS, IC card, UnionPay gold card, telephone banking, bank-bank connection, bank-tax connection, instant payment, provident fund management system, electronic exchange and intra-city clearing.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The government system is physically isolated from the external network, so an information exchange system is needed, which is the front-end processor. Generally speaking, the front-end computer is a physical system, which mainly functions as a gateway to realize the exchange of information between internal and external networks.

What is a front-end processor

The front-end processor refers to the one used on site Intermediate equipment.

The front-end computer generally exists between the front-end client and the back-end server, playing the role of an adapter, that is, converting between different communication protocols, data formats or languages. It also plays the role of managing and scheduling transactions initiated by the front-end. Through the scheduling of the front-end machine, it can reduce the burden on the back-end server, and sometimes acts as a firewall between the client and the back-end server. This can hide the backend function and ensure the security of the backend to a certain extent.

The concept of front-end processor is generally used by banks, securities firms, and telecom operators. These places have many backend core processing systems that provide various interface services to the outside world. If I have some kind of business interface that needs to deal with their back-end system, these units are absolutely not allowed to access their back-end system from our external network. At this time, they ask you or themselves to develop a software to run on their intranet, and then connect the computer running this software to your external network system through dedicated lines or hardware isolation technology. Then the computer running this software will be connected to your external network system from Functionally called a front-end processor.

At present, front-end machines are commonly used in banks including ATM, POS, IC card, UnionPay gold card, telephone banking, securities and bank links, bank and tax links, instant payment, provident fund management system, electronic exchange and intra-city clearing. and other systems.

The role of the front-end processor

• From a network and security perspective, it has the function of isolating the host (one is placed on the intranet In addition, the separation of internal and external network applications) ensures that external applications cannot directly access core services, such as various external interfaces of banks (telecom bill collection, bank-securitization).

• From a business perspective, the front-end processor provides a bridge for communication between business channels and core service hosts. It generally plays the role of managing and scheduling transactions initiated by business channels. It can reduce the burden on the core backend server through the call of the front-end machine. Of course, it also has non-core business processing functions.

• An independent processor system located between the application system server and client, responsible for data format conversion, connection management, business flow management, peripheral scheduling, peripheral processing, and business data transfer The background application service system handles tasks such as this.

• In the C/S concept, C and S are relative terms. Although most of them are fixed, they also depend on the designation. For example, in a bank's business application, the issuance of a request is It cannot come from the backend application server. Taking the example of proxy charging, the front-end processor is an application gateway. In fact, in current applications, the host becomes invisible due to the presence of the front-end processor.

• The business systems at both ends of the government affairs internal and external network need data exchange, and front-end machines are arranged in front of the respective business systems to achieve data exchange.

• The front-end machine is a physical machine, and a front-end switching system is deployed. Responsible for caching the data that needs to be exchanged or exchanged into this server
