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 Fifth 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:
- network "softwarization," which requires unified management of computing, storage,
and network resources for the effective deployment, lifecycle management, and run-time
configuration of generalized virtual functions;
- abstraction models and open standard interfaces, needed for assuring vendor interoperability;
- adaptation and optimization mechanisms, which must be enforced at global and/or
local level for coping with user demand, application requirements, resource unavailability, etc.
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:
- single domain and cross domain orchestration issues
- orchestration of distributed clouds (including fog/edge computing environments)
- integrated network and computing resource control and management
- description, specification, and abstraction languages for orchestration and context-awareness
- control and abstraction of heterogeneous networks
- orchestration in SDN/NFV
- run-time orchestration
- QoS/QoE in software-defined infrastructures
- orchestration for high-availability and resilience in software-defined infrastructures
- orchestration of network slices and data center slices
- software engineering and operating systems techniques applied to orchestration
- optimal orchestration algorithms
- AI techniques for network orchestration and automation
- context-aware orchestration
- functional architectures of orchestrating elements
- testbed experiments on orchestrations
- performance evaluation of orchestration elements
- standardization issues in orchestration
- network programmability for service chaining
- dynamic service composition and delivery
- AI/ML for network resource management
Important Dates and Submission Information
- Paper submission deadline: January 19, 2020 (extended)
- Acceptance notification: February 15, 2020
- Camera-ready papers: March 1, 2020
Paper submissions are handled on-line through the JEMS system.
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 six (6) 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.
