Architectural principles and elements of in-network management

Abstract

Abstract-Recent endeavors in addressing the challenges of the current and future Internet pursue a clean slate design methodology. Simultaneously, it is argued that the Internet is unlikely to be changed in one fell swoop and that its next generation requires an evolutionary design approach. Recognizing both positions, we claim that cleanness and evolution are not mutually exclusive, but rather complementary and indispensable properties for sustainable management in the future Internet.In this paper we propose the in-network management (INM) paradigm, which adopts a clean slate design approach to the management of future communication networks that is brought about by evolutionary design principles. The proposed paradigm builds on embedded management capabilities to address the intrinsic nature, and hence, close relationship between the network and its management. At the same time, INM assists in the gradual adoption of embedded self-managing processes to progressively achieve adequate and practical degrees of INM. We demonstrate how INM can be exploited in current and future network management by its application to P2P networks.

Co-design patterns for embedded network management

“…While we have identified a first set of valuable co-design patterns, more experience is required to conceive and evaluate the benefit of other potential such patterns. Currently, we are pursuing this goal in the context of the innetwork management paradigm within the 4WARD project [4]. Of specific interest is how the co-design patterns can be used to facilitate the transition of current management practices towards future ones, that is, how to move from centralized to more distributed management architectures.…”

“…Figure 1 illustrates the concept of in-network management (INM), an approach to embedding management functions inside of network elements (network nodes) [4]. Figure 1 (left) sketches the structure of a network node, where functional components integrate both service and management logic into a single coherent, deployable entity.…”

“…While some principles are common practice today also in network management, such as SNMP's hierarchical management structures, lack of support for the structured design of embedded management processes persists. We argue in [4] that integrative aspects of management and service realms should be exploited in the design of management solutions, because in a large number of cases, both knowledge and functions for realizing management tasks are shared between both realms. Current principles do not sufficiently assist in this intrinsic design problem, which requires considering design patterns at a finer level of detail.…”

Architectures for the future networks and the next generation Internet: A survey

“…While ANA is a generic architectural framework for autonomic systems composed of autonomic devices, In-Network Management (INM) [41,29,47] proposes a more specific architectural design for embedding management capabilities in all network entities and leveraging the management capabilities that can be achieved as a result of their collaboration . Thus INM advocates a paradigm of 24 management service composition using several autonomous components.…”

Decentralized In-Network Management for the Future Internet

“…In order to support the INM paradigm we propose a framework [1] that allows the implementation of embedded management algorithms to form complex self-organizing management processes. Fig.…”
