Evaluation of message-oriented middleware in the context of a future run control system for CMS

This report offers a comparison between Message-Oriented Middleware (MOM) and Representational State Transfer (REST) as applied to the run control system of the CMS experiment. This assessment is grounded in a configurable prototype, which has been designed to emulate node structures within the run control system, particularly in the form of a hierarchical tree. The insights and empirical findings acquired during the inception, development, and measured results of this prototype can serve as a valuable knowledge base for informing future deliberations regarding the appropriateness and efficacy of choosing between REST and MOM as the preferred communication architecture for the CMS run control system.
