Abstract
MIT SchMUSE (pronounced "shmooz") is a concurrent, distributed, delegation-based object-oriented interactive environment with persistent storage. It is designed to run in a "capricious" network environment, where servers can migrate from site to site and can regularly become unavailable. Our design introduces a new form of unique identifiers called "globally unique tickets" that provide globally unique time/space stamps for objects and classes without being location specific. Object location is achieved by a distributed hierarchical lazy lookup mechanism that we call "realm resolution." We also introduce a novel mechanism called "message deferral" for enhanced reliability in the face of remote delegation. We conclude with a comparison to related work and a projection of future work on MIT SchMUSE.
