Abstract

Cactus is an implementation framework that allows fine-grain customization of Quality of Service (QoS) attributes such as fault tolerance, timeliness and security for software running in networked systems. With Cactus, a service is realized as a composite protocol that is constructed from smaller micro-protocol objects that provide fine-grain task execution and network communication guarantees. This talk gives an overview of the Cactus approach, prototype implementations, and the collection of example communication-oriented services constructed using these prototypes. I will also describe recent research related to the system, including work on supporting coordinated adaptation in networked systems using Cactus.
