With the development of communication technology, the relationship between transmission, reuse and exchange is getting closer and closer, so that they are gradually inseparable. In recent years, people have used the term "Transfer Mode" to describe the transmission, reuse, and exchange in the communication network. The transfer mode can be divided into synchronous transfer mode ATM) and asynchronous transfer mode ATM.
ATM uses space or time-based Fixe

This article puts forward the intelligent firewall, this kind of firewall is smarter and smarter, overcomes the traditional firewall's "one tube to die, one puts on the chaos" condition, the revision above firewall's important assumption is "refuses to guarantee the security, releases also must guarantee the security". The new smart firewall changes the concept of "exit" to the concept of "gateway", and all packets passing through the "gateway" must be inspected by the firewall. In contrast to t
