The complete guide to technologies and protocols for delivering seamless mobile Internet experiences In Building the Mobile Internet, three leading mobility architects and implementers from Cisco present complete foundational knowledge about tomorrow's mobile Internet. The authors cover everything from market trends and user expectations to the latest technical approaches for making the Internet ';mobile by design.' Writing for senior technology decision-makers and network design professionals, the authors explain the relatively static nature of the Internet's original protocols and design, discuss the concept of ';mobility,' and identify evolving mobility requirements. Next, they thoroughly explain each of today's most promising techniques for building mobility into the Internet, from data link layer to application layer. For each layer, the authors cover mechanisms, protocols, relevant Wi-Fi and cellular architectures, and key use cases. Using this book's guidance, mobile network executives can define more effective strategies, network designers can construct more effective architectures, and network engineers can execute more successful migrations. Understanding key mobility market trends: device proliferation, accelerating consumption, and radio-specific scalability problems Reviewing the challenges that mobility presents to conventional Internet architectures Understanding nomadicity, including authentication for users moving across networks and operators Identifying opportunities to address mobility at the data link layer Comparing and using network layer solutions to deliver seamless mobility and session continuity Integrating mobility functionality into the transport/session layer Adding mobility functionality to the application layerincluding support for moving media sessions between devices Redesigning Internet architecture to enable long-term improvements to mobility This book is part of the Networking Technology Series from Cisco Press(R), which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
