Abstract—The future Internet evolution is driven by appli-cations that require simultaneous real-time access to multipleheterogeneous IT (e.g. computing and storage) resources in¬terconnected by high-speed optical networks. Service orientedarchitectural frameworks have been considered to improveservice delivery in this environment by organising distributedheterogeneous resources owned by multiple providers.
In this paper, we discuss a service oriented architecturalframework tailored to the needs of future Internet applications.The framework introduces the capability to orchestrate theprovisioning of distributed heterogeneous resources ownedbymultiple providers. Central to the framework is a novel resourceorchestration model. This model focuses on the optimized se¬lection of heterogeneous IT and network resources owned bydifferent Infrastructure Providers (InPs). The proposed modelaims to achieve a global optimum from both the end-users’ andInPs’ point of view across different administrative domains. Aninteger linear program (ILP) is formulated to obtain optimalresults that maximizes the number of accepted requests whileminimising resource usage. It is compared against a co-schedulingILP model, whose objective is to maximise the number ofaccepted requests only. We then propose a heuristic solutionforscalability. Its performance is compared against (i) our proposedILP (ii) a co-scheduling heuristic that aim to maximise thenumber of accepted requests only and (iii) an algorithm thatdoes not take into account cross-domain optimisations. Finally,two online algorithms for operational scenarios is proposedwhichoutperforms three benchmark algorithms.
