Definition of "Dumb Network" |
A dumb network is one that provides the physical interconnection between nodes but not much processing to support signaling. The Internet is often cited as a dumb network relative to the public switched telephone network. The telephone system is considered an "intelligent network" because the intelligence required for operation is carried within the network, while the end devices (telephones) are simple devices. (Recent telephone control systems - Advanced Intelligent Network and Signaling System 7 - provide even more intelligence in the network.) The Internet takes the opposite approach: the network simply transports packets of data without needing to know anything about them and the end devices (computers, for example) contain the intelligence. This approach is sometimes referred to as "dumb network, smart devices." |
