A Framework for Real-Time Service-Oriented Architecture

Service-oriented architectures (SOA), though widely accepted in a

variety of industries, must be enhanced to support real-time

activities in order to gain even greater adoption. We present a novel

architecture for real-time SOA to support predictability in business

processes. Based on a user-specified process and deadline, our

architecture, containing global resource management and  business

process composition components, can reserve resources in advance for

each service in the process to ensure it meets its end-to-end

deadline. This is facilitated by also creating a real-time enterprise

service bus middleware that manages utilization of local resources by

using efficient data structures and handles service requests via

reserved bandwidth. We describe an initial implementation that uses

real-time Java and Solaris 10 and demonstrate that our reservation

data structures are both efficient and adaptable to dynamic real-time

environments.
