Resilience, survivability, and heterogeneity in the postmodern internet
James P. G. Sterbenz · 2009
Society increasingly relies on computer networks in general, and the Internet in particular. Consumers rely on networks for access to information and services, personal finance, and for communication with others. The Internet has become indispensable to the routine operation of businesses and to the global economy. The military depends on network centric operations and warfare. Governments depend on networks for their daily operation, service delivery, and response to natural disaster and terrorist attacks. Furthermore, the Internet is being used in ways not anticipated by its designers and evolution of the protocols, in particular, TCP, IP, BGP, DNS, and HTTP. Emerging application paradigms and mashups, coupled with usage scenarios that are increasingly disconnected and mobile, challenge the current architecture. This has been recognised by research and development initiatives including NSF FIND (Future Internet Design), GENI (Global Environments for Network Innovation), and EU FIRE (Future Internet Research and Experimentation). This presentation will focus on two key aspects of the future Internet: resilience and heterogeneity.
