[email protected] O A S I S P R O V I D E S A P U B L I C LY A V A I L able, locality-aware server-selection infrastructure. Replicated servers adopting OASIS each run a small application that communicates with the OASIS infrastructure, sharing information about their current load levels and their measured network response times to selected IP addresses. OASIS in turn can redirect unmodified clients to nearby and/or lightly loaded live replica servers. In this article, I explain how OASIS works, provide some performance analysis, and describe how services can start using OASIS.

Testing remains an important aspect of checking software correctness. Manually constructed test suites are one option: they typically complete quickly, but they require human involvement in producing test cases, and their coverage may be limited. Recently, symbolic execution and concolic execution have been investigated as alternatives to test suites. These approaches require little manual inte...

متن کاملArchitecture of the Oasis Mobile Shared Virtual Memory System
Oasis is a memory-based storage system designed to support collaborative mobile computing applications. These applications require peer-to-peer and client-server interactions in conditions of less than ideal network connectivity. The architecture is based on a memory model where the address space is logically partitioned into regions used for sharing. Mobile units may disconnect from the backbo...
