WP4 - In-Network Management

In-Network Management is a novel paradigm to manage networks in the Future Internet. It will be based on a lean architecture to operate new services in the Future Internet. Discovery of network capabilities and adaptation of management operation to current working conditions are key elements in the novel management paradigm.

Traditional networks: management as external processes

In traditional Internet management, the management functionality resides outside the network, in dedicated management stations and servers. In commercial networks, interactions between these elements often occur out-of-band, through special communication networks. For emerging large-scale, dynamic network environments however, the approach turned out to be inadequate and alternative approaches must be developed.

A new Management Paradigm

In-Network Management is a new paradigm for network management, where management functions come as embedded capabilities of the devices.
With this approach, network elements have embedded “default-on” management capabilities, consisting of several autonomous components which interact with each other in the same device and with components in neighbouring devices. Glued together with a set of discovery and self-organizing algorithms, the network elements form a thin “management plane” embedded in the network itself.

In-Network management.

The In-Network Management paradigm can be interpreted as pushing management intelligence into the network, and, as a consequence, making the network more intelligent: as a consequence, objectives and costs of management operations can be adapted according to local working conditions. The network, which now includes the management plane as a part, can execute end-to-end management functions on its own and perform, for instance, reconfigurations in an autonomous fashion. It reports results of management actions to an external management system, and it triggers alarms if intervention from outside is needed.

The architecture of In-Network management first of all models how management capabilities are embedded inside the services of a node. On this basis, it is then possible to compose them, in such a way that the embedded functions are coordinated with each other. Out of smaller autonomous components, more complex management functions can be constructed in the management plane.

The goal of In-Network Management is to achieve scalable, robust management systems with low complexity for large-scale, dynamic network environments. The guiding principles to achieve this goal are decentralization and self-organization.
