Both, end-to-end (E2E) transport network architectures and associated management and operations architectures are undergoing transformations, as new requirements in network management and control are continuously amended by emerging network and computing models and paradigms, advances in autonomic networking, network and resources virtualization, cloud computing, SDN (Software-Driven/Software-Defined Networking), Network Functions Virtualization (NFV), and the advent of wireless sensor networks, ad hoc networks, overlay networks, grid networks, optical networks, multimedia networks, storage networks, Machine-to-Machine (M2M) and Internet Of Things (IoT) communication networks, the convergence of next generation networks (NGN), Future Internet, SON (Self-Organizing Networks), or even nano-networks, etc. On the other hand, research communities and industry are seeing the need to increasingly work together to bring about faster pace to standardization and adoption of new technologies, including the launching of standardization activities for future networks, since the joint efforts are critical in fostering innovation and deployment of new technologies by industry. To mention a few initiatives that are calling for collaboration between academia and industry, the activities of the ETSI AFI Group on Autonomic Future Internet are producing specifications that can be adopted by both the academia and industry in order to enable to research and develop inter-operable autonomic and self-managing networks. The other initiative that works closely with AFI and other standardization groups such as 3GPP, TMF and ITU-T, is the NGMN NGCOR initiative on the emerging vision of converged management of fixed and mobile networks that enables OPEX reduction. In all these initiatives there are emerging hot topics that require the attention of research communities, towards researching solutions that are aligned by standardized frameworks in order to guarantee interoperability in emerging and future network technologies. Also, increasingly ubiquitous network environments require new management strategies, which can cope with resource constraints, multi-federated operations, programmability, scalability, dependability, context awareness, security, mobility and probability, etc. To bring complex network systems under control, it is necessary for the ICT industry to move to autonomic management and control, autonomic features in both the data and control planes of the network, context-aware management and self-management systems in which technology itself is used to manage technology. Though the field has matured and standards are emerging in ETSI AFI, new theoretical approaches are still needed in resolving the challenging problems in network management, including adoption of unified network architectural reference models that incorporate autonomic, cognitive and self-management principles, as well as the emerging paradigms of SDN/programmability and NFV. According to both industry and academia, the next steps that must be pursued is the adoption of a commonly-shared unifying reference model for autonomic networking, cognitive networking and self-management (such as the GANA—“Generic Autonomic Networking Architecture” Reference Model from ETSI AFI) by all stakeholders (including research communities), to enable to continue research agendas within standardized frameworks and implementing interoperable self-managing networks. Also important now is the subject of algorithms for Autonomic Functions (Decision-making-Elements/Engines), that conform to the GANA Model and enable to realize Self-Optimization and Self-Learning and Reasoning (Cognitive Behavior) in diverse networks, e.g. Broadband Forum Architecture, 3GPP architecture, NGN/IMS, Wireless Ad-hoc/mesh networks, M2M/IoT, SDN-based architectures, etc. Another important subject is that of frameworks that unify the emerging paradigms of SDN, NFV and Autonomic Management & Control within the same holistic standardized framework. Relationships between Autonomic Management & Control and SDN are being established, and efforts to unify associated Reference Models have started, i.e. unification of the GANA Model and SDN-enabling frameworks. This workshop will provide a forum to researchers to propose theories and technologies on the management of various types of emerging networks and services, share their experience of IT and telecommunications industries and discuss future management solutions for emerging networks and services. The workshop will also give the opportunity for the various communities and stakeholders to show results of adopting the ETSI AFI GANA Reference Model in research work and prototyping, while at the same time presenting and discussing the ways in which various research results can be contributed to the evolution of the Reference Model (as it becomes a commonly-shared framework for autonomics, cognitive networking and self-management). The workshop also welcomes proposals on early work on 5G architectural frameworks that glue together SDN/Programmability, Virtualization, Autonomic Management & Control functions, network heterogeneity, and service orchestration.
