A Framework for Real-Time Service-Oriented Architecture

Abstract

Service-oriented architectures (SOA), thoughwidely accepted in a variety of industries, must be enhancedto support real-time activities in order to gain evengreater adoption.We present RT-Llama, a novel architecturefor real-time SOA to support predictability in businessprocesses. Based on a user-specified process and deadline,our architecture, containing global resource managementand business process composition components, can reserveresources in advance for each service in the process toensure it meets its end-to-end deadline. This is facilitatedby also creating a real-time enterprise middleware thatmanages utilization of local resources by using efficient datastructures and handles service requests via reserved CPUbandwidth. We demonstrate that RT-Llama’s reservationcomponents are both efficient and adaptable to dynamicreal-time environments.
