To address the challenges faced by users in personal computing, the Internet Suspend/Resume (ISR) is developed. ISR is a pervasive computing technology that rapidly personalizes and depersonalizes anonymous hardware for transient use. As its name implies, ISR mimics the closing and opening of a laptop. Hardware virtualization and file caching are the keys ot ISR's precise customization and simple administration. ISR layers virtual machines on a location-transparent distributed file system that aggressively caches data. Simplicity was the driving force behind the decision to use a VM-based approach for state encapsulation. A key obstacle to using ISR is high resume latency. Fortunately, numerous consideration can be exploited to mitigate these delays. These include temporal locality, proactivity, and state synthesis. ISR uses the Coda distributed file system for data storage and transport. This choice was based on four key factors that are mentioned in this article. INSET: User Mobility Evolution.. |
