Reconsidering Internet mobility

摘要: Despite the popularity of mobile computing platforms, appropriate system support for operation is lacking in Internet. The paper argues that this not lack deployment incentives, but because a comprehensive architecture efficiently addresses needs applications does exist. We identify five fundamental issues raised by mobility: location, preservation communication, disconnection handling, hibernation, and reconnection, suggest design guidelines attempts to Internet mobility. In particular, we argue good should: (i) eliminate dependence higher protocol layers upon lower-layer identifiers; (ii) work with any application-selected naming scheme; (iii) handle (unexpected) network disconnections graceful way, exposing its occurrence applications; (iv) provide mobility services at nodes themselves, rather than via proxies. Motivated these principles, propose session-oriented, end-to-end called Migrate, briefly examine set it should provide.
