Future Internet Elements: Cognition and Self-management Design Issues

Abstract

The scope of this paper is to introduce an innovative paradigm for cognitive self-managed elements of the Future Internet. The present Internet model is based on clear separation of concerns between protocol layers, with intelligence moved to the edges, and with the existent protocol pool targeting user and control plane operations with less emphasis on management tasks. Future Internet shall be engineered based on cognitive behavior with a high degree of autonomy, by proposing the operation of selfmanaged Future Internet elements around a novel hierarchical feedback-control cycle. The concepts are based on a hierarchical Distributed Cognitive cycle for System & Network Management (DC-SNM) which aims at facilitating the promotion of distributed management. The management approach encompasses a hierarchical distribution of cognitive cycles, breaking down the execution and decision making levels to (autonomic) network elements, network domain types and up to the service provider realm in order to address management, dynamic organization and (re)configuration of future internet elements.

Towards Cognitive Internet: An Evolutionary Vision

“…In [25], Kousaridas et al argue that next generation Internet architecture should be based on cognitive behavior by proposing a novel hierarchical feedback-control cycle in order to provide self-management capabilities. The proposed approach (called Self-NET) encompasses a hierarchical distribution of cognitive cycles in order to address self-organization and dynamic reconfiguration of network elements.…”

Challenges for Enhanced Network Self-Manageability in the Scope of Future Internet Development

“…Besides, the introduction of cognition in networks can contribute towards overcoming structural limitations of current infrastructures -which render it difficult to cope with a wide variety of networked applications, business models, edge devices and infrastructures-so as to guarantee higher levels of scalability, mobility, flexibility, security, reliability and robustness. Self-NET principle design is based on high autonomy of NEs in order to allow distributed management, fast decisions, and continuous local optimization of existing networks or of specific network parts [20]. The three distinct phases of the Generic Cognitive Cycle Model-GCCM (i.e.…”

Management of network and energy resources in cognitive and self-organizing wireless networks

“…For the deployment of a SON, each AP incorporates a Cognitive Network Manager (CNM), where energy saving as well as Coverage and Capacity Optimization (CCO) algorithms are placed [5]. In the context of this dissertation we present two types of a CNM a) simple CNM that is referred to as Network Element Cognitive Manager (NECM) and b) domain CNM entitled Network Domain Cognitive Manager (NDCM) [6].…”
