Implementing Replication of Objects in DOORS-The Object-Oriented Runtime System for Edge Computing

Aiming for simplicity and efficiency in the domain of edge computing, DOORS is a distributed system expected to scale up to hundreds of nodes, which encapsulates application state and behavior into objects and gives them the ability to exchange asynchronous messages. DOORS offers semi-synchronous replication and the ability to explicitly move objects from one node to another, as methods to achieve scalability and resilience. The present paper gives an outline of the system structure, describes how DOORS implements object replication, and describes a basic set of measurements, yielding an initial set of conclusions for the improvements of the design.

Automated summary

The DOORS system is designed for simplicity and efficiency in edge computing, expected to scale up to hundreds of nodes. It encapsulates application state and behavior into objects and allows them to exchange asynchronous messages. The system provides semi-synchronous replication and the capability to move objects between nodes, aiming for scalability and resilience. The paper outlines the system structure, describes object replication in DOORS, and presents a basic set of measurements for design improvements.
