Introduction The distributed nature of Wireless Mesh Networks (WMNs) allows them to benefit from multiple autonomic functionalities. However, the e

18、xisting landscape of self-x solutions (e.g. self-configuration) is fragmented and the lack of a standardized framework through which interoperable autonomics can be developed has been hampering adoption and deployment of autonomics in real world service networks. There is a need for a standardized a

19、rchitectural framework that enables to comprehensively support and integrate interoperable components for autonomicity in WMNs. Such an architecture (autonomicity-enabled wireless mesh architecture) is the subject of the present document. The proposed autonomic wireless mesh architecture is an insta

20、ntiation of the GANA (Generic Autonomic Network Architecture) Reference Model - a standards based approach to autonomics, onto the wireless mesh network architecture. The provided guidelines can now help researchers and engineers build autonomicity-enabled WMNs using a standardized framework that en

21、ables adoption and deployment of autonomics by industry, thereby enabling researchers and engineers to contribute to further evolution of the framework described in the present document in ETSI. It has to be noted that the same approach being applied to introducing autonomics in mesh networks in the

22、 present document also applies to Ad-hoc wireless networks, and so the present document covers both aspects - hence the document title “Autonomicity and Self-Management in Wireless Ad-hoc/Mesh Networks: Autonomicity-enabled Ad-hoc and Mesh Network Architecture“. The GANA model is being instantiated

23、onto various reference network architectures to create autonomics-enabled reference network architectures. For example, ETSI recently published ETSI TR 103 404 i.17, which addresses Autonomicity and Self-Management in the Backhaul and Core network parts of the 3GPP Architecture through GANA instanti

24、ation onto the Backhaul and Core (EPC) network parts of the 3GPP architecture. Readers may also find ETSI TR 103 404 i.17 helpful in further understanding how GANA is being applied in various networks. Readers may also follow up on ongoing work in ETSI on instantiation of the GANA onto the Broadband

25、 Forum (BBF) architectures that incorporate SDN (Software-Defined Networking) and NFV (Network Functions Virtualization). To obtain some guidance and information on the various types of stakeholders who should get involved and contribute to standards on self-managing future networks, readers may ref

ETSI ETSI TR 103 495 V1.1.1 (2017-02) 5 1 Scope The present document aims to provide recommendations for the introduction of autonomics (management and control intelligence) into Ad-hoc and Mesh Network architectures and their associated management and control architectures. The

27、present document describes: Autonomicity-enabled Ad-hoc and Mesh Network Architecture that is a result of the instantiation of the GANA (Generic Autonomic Networking Architecture) Reference Model on the Ad-hoc and Mesh Network architecture to enable developers of autonomics to introduce autonomics i

28、n the architecture Relevant autonomicity-enabled functions and operations Relevant GANA Decision Elements (DEs) and Reference Points between those DEs The present document describes the specific desirable features for autonomic management and control of Ad-hoc and mesh network functions through the

29、introduction of Decision Elements (DEs) and their associated control loops at the Network, Node and Function level of the GANA reference model. The Protocol level needed to be additionally addressed due to the need for accommodating the specifics of Ad-hoc and mesh set-ups. 2 References 2.1 Normativ

47、 and entities Self-configuration (auto-configuration), Self-diagnosing, Self-repair (Self-healing) Self-optimization, and other self-* properties NOTE 1: Autonomic Networking can also be interpreted as a discipline involving the design of systems (e.g. network nodes) that are self-managing at the in

48、dividual system levels and together as a larger system that forms a communication network of systems. NOTE 2: The term “autonomic“ comes from the autonomic nervous system (a closed control loop structure), which controls many organs and muscles in the human body. Usually, humans are unaware of its w

49、orkings because it functions in an involuntary, reflexive manner - for example, humans do not notice when their heart beats faster or their blood vessels change size in response to temperature, posture, food intake, stressful experiences and other changes to which human are exposed. And their autonomic nervous system is always working i.18.
