Using principle patterns to optimize real-time ORBs

Abstract

Increasing quality-of-service requirements pose challenges in both design and optimization for real time CORBA middleware. The authors describe TAO (The Ace ORB), an object request broker that provides end-to-end QoS guarantees. In discussing TAO, we focus on object-adapter and ORB-core optimizations in three key dimensions in high performance, real time ORB end system design: server-side concurrency, memory management, and CORBA request demultiplexing.
