For many years, embedded systems were self contained machines that performed a specific function or a limited set of functions. They were used as flight control systems, motor controllers, engine control systems and the like.
Within the past 10 years, however, embedded systems have begun to interact with systems around them, communicating via the internet. Just by adding a TCP/IP stack, an embedded system taps into the universe of the internet and exchanges data and operational parameters with any other connected system.
In this revolution, embedded systems became connected devices and they connected our world in the process. Today, we take for granted that our TiVo box can be accessed on the web and manufacturing organisations demand that factory floor controllers upload operational statistics and major events to corporate database systems via the internet. But, as millions of mobile phones or PSPs gain internet access, the infrastructure became strained accommodating all these new nodes.
