Autonomic Management & Control (AMC) and Automated Management of Networks and Services * Definition: Autonomic Management & Control (AMC) of Networks and Services: “Autonomic Network Management & Control (includes the notion of Autonomic Networking)” can be expressed in the following way: AMC = Autonomics in the Management Plane + Autonomics in the Control Plane (whether distributed or centralized) AMC is about Autonomics (i.e. control-loops) introduced in the Management Plane as well as Autonomics (i.e. control-loops) introduced in the Control Plane (whether the control-plane is distributed or centralized). A control-loop realizes self-* features (self-configuration, self-optimization, etc). Autonomic Management (Control-Loops, with Learning and Reasoning to effect adaptation) can be contrasted to Automated Management (workflow reduction and automation i.e. automation of the processes involved in the creation of network configuration input using specialized Task Automation Tools, e.g. Scripts, network planning tools, policy generators for conflict-free policies)
Autonomic Management & Control (AMC) and Automated Management of Networks and Services “Control” in AMC is about: “Control Logic(s)” that realize a control-loop in order to dynamically adapt network resources and parameters or services. The control-logics, as a software or a behavior specification, may be loaded or replaced in nodes and network Notion of Software-Driven Networks or Software-Empowered Networks From an architecture perspective, a control-loop can be based on a “distributed model” (for fast control-loops). That means, the logic is embedded in the nodes (Physical or Virtualized). Whereas, a “centralized model” (for slow control-loops), the logic is embedded (implemented) outside of the node. Both kinds of control-loops act towards a global goal to ensure a stable state of the network. A control-logic can negotiate with another control-logic, to realize dynamic adaptation of network resources and parameters, or services, via reference points.

AFI GANA Reference Model, and Modularization of logically centralized Control Software (GANA Knowledge Plane) Decision Elements (DEs) = Centralized and Distributed Control Software Logics (DEs) that operate in different time-scales but interworking harmoniously in realizing autonomic behaviors DE algorithms imply DE vendor differentiation. DEs MAY be “loaded or replaced” notion of “Software-Driven or Software-Empowered Networks” i.e. the broader picture than Software-Defined Networks 3-Levels of Hierarchical Control- Loops demonstrate how Autonomics can be introduced in architectures. “Fast Control-Loops” in the Nodes/NEs, while “Slow but network-wide Control-Loops“ should operate in the outer centralized GANA Knowledge Plane (i.e. SDN – Controller & Net- Apps realm) MBTS: Model-Based-Translation Service ONIX :Overlay Network for Information eXchange

As is being done for other architectures (BBF,Mesh, IMS,etc), the GANA can be instantiated onto the PTDN to create an Autonomics-Enabled PTDN Architecture See next slides on Guidelines on how to perform Instantiation of GANA Model onto a target architecture to create an Autonomics- Enabled Architecture
Steps Towards Architectural Enhancements and Autonomic Behaviour Specifications for ANY Architecture 1. Instantiate Functional Blocks and Reference Points for Autonomicity/Self-Management from AFI’s Reference Model onto ANY Architecture and its Management Architecture Functional Blocks of the Knowledge Plane (Net-Level-DEs, MBTS, ONIX) Network-Level-DEs perform the role of Policy-Decision Points (PDPs) and so PDPs can be evolved by the DEs Network-Level-DEs (in the Knowledge Plane) evolve EMSs or NMSs ONIX Information sharing/exchange servers facilitate advanced Auto-Discovery Establish the type of Autonomic Functions (Decision Elements and their associated Control-Loops and Managed Entities) that should be instantiated into what type of Network Elements How are the Network Elements, EMSs/NMSs enhanced by DEs and the Reference Points instantiated to all the Functional Blocks that are specific to Autonomics/Self- Management 2. Use the Instantiated Functional Blocks (FBs) and Reference Points for Autonomicity/Self- Management from the Reference Model, to specify Autonomic Behaviours within the Management and the E2E Transport Architecture Specify Behaviours of instantiated GANA FBs (including DEs and their Control- Loops) 20
Reflections on IPv6 and Autonomic Networking IPv6 Forum is collaborating with ETSI in TC NTECH AFI WG, following on EC-FP7 EFIPSANS project results on IPv6 & Autonomics : ETSI-IPv6 Forum MoU & work in AFI) There are new potential work items related to IPv6 and Autonomic Networking that were proposed in ETSI AFI during the ETSI 2013 Future Networks Technologies workshopworkshop It is now necessary for industry to consider linking Autonomic Networking Standardization with IPv6 by launching the proposed new Work Items in ETSI AFI
IPv6 and Autonomic Networking Standards New AFI Work Items are envisaged on the IPv6 Feature(s) Usage Requirements in Autonomic Networks: Reference: ETSI Future Networks Workshop 2013: The IPv6 Community can launch the following Work Items envisaged by ETSI NTECH / AFI: IPv6-Feature(s) Usage Requirements in Autonomic 3GPP and Non-3GPP Mobile Network Reference Architectures; IPv6 Features that enable the Autonomics IPv6-Feature(s) Usage Requirements in Autonomic Broadband Forum (BBF) Reference Architecture; IPv6 Features that enable the Autonomics IPv6-Feature(s) Usage Requirements in Autonomic NGN/IMS Architecture; IPv6 Features that enable the Autonomics IPv6-Feature(s) Usage Requirements in Autonomic TISPAN CDN Reference Architecture; IPv6 Features that enable the Autonomics IPv6-Feature(s) Usage Requirements in Autonomic Wireless Adhoc/Mesh/Sensor network architectures; IPv6 Features that enable the Autonomics
Some Reflections on 5G There are now a lot of activities around the 5G related Topics, both in Research (in particular) and also in Industry (e.g. NGMN, TMForum / ZOOM, and other Groups) In regard to 5G, we can observe that the following points are worthy to take note of: SDN, NFV and AMC will play key roles in the 5G architecture, due to the complementarities of the three paradigms in addressing the dynamics, flexibility in network & service compositions, and intelligence expected in 5G networks Regarding Autonomics: 5G embedded Autonomic Functions (AFs) are enablers for the edge, backhaul and core network nodes to intelligently, optimally and adaptively provision resources in such a way as to handle the anticipated huge traffic volumes and diversified traffic flows of various requirements that must be transported over the 5G network. Also, advanced Autonomicity in network & services resilience is needed. In 5G, more advanced Self-Organizing Network (SON) Functions could be envisaged, beyond SON functions already introduced for 2G/3G/4G). Enrichment of SON with advanced Autonomicity/cognitive algorithms/behaviors is also desirable; and also may be desirable is autonomic coordination of SON functions on inter-system interfaces of Multi-RATs and Fixed/Mobile convergence interfaces.
