“…It is also noted that such a mechanism can be implemented in an asynchronous manner, i.e the components of θ are updated in a round-robin fashion, or at random instants, and the average frequency of update is the same for all components. The reader can refer to [17][chapters [6][7][8] for the round-robin updates and [18][chapter 12] for the random updates. Asynchronous implementation is important in practice because if the SONs are not co-located, maintaining clock synchronization among the SONs would generate a considerable amount of overhead.…”

“…The deployment of multiple control loops raises the questions of conflicts, stability and performance. The topics of conflict resolution, coordination, and a framework for managing multiple SON functionalities are receiving a growing interest (see for example [5]- [7]). Most contributions that have addressed the coordination problem between specific SON functionalities, provide a solution implemented in a centralized [8], [9] or distributed [10] fashion.…”

Abstract-The fast development of the Self-Organizing Network (SON) technology in mobile networks renders the problem of coordinating SON functionalities operating simultaneously critical. SON functionalities can be viewed as control loops that may need to be coordinated to guarantee conflict free operation, to enforce stability of the network and to achieve performance gain. This paper proposes a distributed solution for coordinating SON functionalities. It uses Rosen's concave games framework in conjunction with convex optimization. The SON functionalities are modeled as linear Ordinary Differential Equation (ODE)s. The stability of the system is first evaluated using a basic control theory approach. The coordination solution consists in finding a linear map (called coordination matrix) that stabilizes the system of SON functionalities. It is proven that the solution remains valid in a noisy environment using Stochastic Approximation. A practical example involving three different SON functionalities deployed in Base Stations (BSs) of a Long Term Evolution (LTE) network demonstrates the usefulness of the proposed method.

“…This tool will be used by human operators for expressing their objectives, enabling transformation of the high‐level objectives to network‐understandable policies, and thus shifting from network management to network governance. Moreover, this interface will perform visualization of the network status for the operator, enabling the enlightenment of administrators/operators for critical states of self‐managed operations/devices at a glance, and their access to accurate, detailed and up‐to‐date network information relevant to managed resources and managed networked systems configuration, status, context and alerts, for all the network segments .…”

“…SID is a well‐known information model, which models all the data that is in use by telecommunication operators’ business processes and allows its extensibility. Thus NEM is considered as a new class that is inherited from the root class within the SID . Respectively, the policy structure is effected in the framework of the SID policy model, which integrates the DEN‐ng (Directory Enabled Networks—next generation) policy information model into the SID framework.…”

A survey of autonomic networking architectures: towards a Unified Management Framework

SUMMARY Academic and industrial research initiatives have sought to make fully autonomic networks a reality. Some of these initiatives pursued a holistic approach, while others focused on setting up functionalities for specific networking domains. These efforts did not succeed in being extensively deployed, because the goals of network operators were not satisfactorily met. These goals include unification of management operations, enablement of end‐to‐end management and enhancement of the overall system performance in a trusted way, while reducing management cost. In this paper, we analyse a set of existing autonomic management architectures and frameworks with respect to a selected set of criteria. We then identify missing parts and challenges and propose a framework to unify the most promising attributes towards a novel approach of realization of autonomic networking management. We call this proposal Unified Management Framework (UMF). Copyright © 2013 John Wiley & Sons, Ltd.
