Overview
This research project used automated binary instrumentation to implement
lightweight process migration on the .NET Common Language Runtime (CLR). The
technique of modifying program binaries meant process migration could be
used in a variety of settings, from resource-constrained PDAs to high-end
servers; in a variety of environments, from unprivileged applets to trusted
code in LANs; for a variety of programming languages, from VB.NET and C# to
Gardens Point Component Pascal; running on a variety of Common Language
Infrastructure (CLI) implementations, including the CLR, the .NET Compact
Framework, Mono, and the Shared Source CLI (aka 'Rotor').
We have used lightweight mobile processes in the following projects:
- Integrating web services and mobile agents, where mobile agent technology
is made available to legacy clients via ordinary web services. Mobile agents
communicate via web services to implement dynamic web services.
- Migratory applications that can be shared between desktop PCs and PDAs
via infared or the web.
- Delivering services based on a user's physical location.
- Checkpointing long-running jobs in the G2 cycle stealing system.
