Self-organising Management Overlays for Future Internet Services

Context-aware control of user-centric virtual networks: Centralized vs distributed approaches

“…Concerning the distributed control platform presented in Section 4, we implement the signaling processes and messages that allow each WMN node to select any of its supported VNs to be updated according to the metric defined in expression (8). Moreover, each WMN node periodically announces its stored information tuples to its 1-hop physical neighbors (the periodicity of this process is 500 ms), and these tuples are then disseminated along a maximum number of hops TTL m ¼ f1; 2; 3g.…”

“…A similar approach is proposed in [7] to form a policy layer composed by a set of network agents, which dynamically cooperate to manage the behavior of a service-aware overlay network according to the context of users, networks and service providers. The authors of [8] define a protocol to select a set of network nodes that act as distributed service directories; these directories keep track of the different types of services that are currently available in the network, each being able to access the services that are needed to implement more tailor-made services that consumers want. In the presented approaches, the overlay topologies are dynamically configured and adapted to meet services' delivery and quality needs.…”

An enabling platform for autonomic management of the future internet

“…The overlay management backbone approach [8] consists of the use of distributed hash tables (DHT) for implementing distributed self-organizing activity management. By using DHT, network components are associated with specific tasks in an autonomic and dynamic way, such as collecting a specific information type or monitoring.…”

Platforms and Software Systems for an Autonomic Internet

“…It provides knowledge and expertise to enable the network to be self-monitoring, self-analyzing, selfdiagnosing, and self-maintaining or -improving [12]. [14].…”
