The current industry trend of convergence between computing and networking eco-systems clearly shows that software will play an unprecedented dominant role also in future communication environments. Computing, storage, and connectivity services, as well as any other present and future application instances, will be deployed in the form of virtualized assets within a software-defined infrastructure running on top of general-purpose processing and communication hardware, all managed and made available under the cloud "As A Service" paradigm. This technological convergence and infrastructure sharing between the computing and communication systems portend a scenario with a "fog" of micro-clouds composed of generalized virtual functions providing both applications and network services that supplement those deployed in traditional cloud datacenters.

The Fourth IEEE Workshop on Orchestration for Software-Defined Infrastructures (O4SDI) addresses the challenges that will facilitate orchestration and programmability of generalized virtual functions in Software Defined Infrastructures (SDI), enabling cloud and network providers to deploy integrated services across different resource domains. Orchestration mechanisms will facilitate the live deployment and lifecycle management of these virtual elements, at the application level, the server level, and the network level within a single domain and across multiple domains. Without such orchestration it will not be possible to enable dynamic establishment of generalized virtual functions chains, according to service requirements.

These challenges of orchestration are many-fold, with many open questions that need to be addressed in the areas of:

Topics of Interest

O4SDI aims at providing an international forum for researchers and practitioners from academia, industry, network operators, and service providers to discuss and address the challenges deriving from such emerging scenario where systems, processes, and workflows used in both computing and communications domains are converging.

The workshop welcomes contributions from both computing and network-oriented research communities, with the aim of facilitating discussion, cross-fertilization and exchange of ideas and practices, and successfully promote innovative solutions toward a real programmatic use of software-defined infrastructures as a whole. Contributions that discuss lessons learnt and best practices, describe practical deployment and implementation experiences, and demonstrate innovative use-cases are especially encouraged for presentation and publication.

We are particularly interested in papers that cover, but are not limited to, the following topics:

Important Dates and Submission Information

Further information on final paper submission is available at:

Prospective authors are invited to submit high-quality, original technical papers for presentation at the workshop and publication in the O4SDI Proceedings and IEEE Xplore. Papers must be written in English, unpublished and not submitted elsewhere. Full papers must be formatted as the standard IEEE double-column conference template. All final submissions should have a maximum paper length of five (5) printed pages (10-point font), including figures, without incurring additional page charges.

To be published in the Workshop Proceedings and to be eligible for publication in IEEE Xplore, at least one author of an accepted paper is required to register and present the paper at the workshop. The IEEE reserves the right to exclude a paper from distribution after the conference (including its removal from IEEE Explore) if the paper is not presented at the conference. Papers are reviewed on the basis that they do not contain plagiarized material and have not been submitted to any other conference at the same time (double submission). These matters are taken very seriously and the IEEE Communications Society will take action against any author who engages in either practice.
