Mobile terminals are becoming the primary Internet devices for most of the people in the world, and smartphone users are generating on average 10 times more traffic than other users. Current forecasts expect mobile data traffic to grow by 300-500 percent over the next 10 years, whereas the capacity of cellular infrastructure only doubles every two years. In order to cope with these challenges, it is critical that telecom operators and Internet service providers adopt smarter traffic management and pricing strategies. By 2020, more than half of the revenue in the global broadband industry is likely to be from two business models: "wholesale" and "two-sided" fees for improved access capacity and quality. These models require enforcement of stringent policy control mechanisms for bandwidth management, quality of service (QoS), and service level agreements.
