ABSTRACT
The history of the Internet may be traced back to the late 1960s with the development of the Advanced Research Projects Agency Network (ARPANET) [2]. It has grown from 4 hosts in 1969 to around 147 million hosts and 38 million sites in 2002, and today over 2.1 billion people used the services of the Internet around the globe [2, 3]. In 2001, there were over 52,000 Internet-related failures and incidents. The reliability and stability of the Internet has become extremely important to the global economy and other areas, because Internet failures can cause millions of dollars in losses and interrupt the day-to-day routines of millions of end users [4]. This chapter presents various important aspects of software safety and Internet reliability.
