D-4.4 In-Network Management System Demonstrator

The deliverable D-4.4 In-Network Management System Demonstrator is available for review and comment.
4WARD proposes a novel approach of network management, called In-Network Management (INM). Its basic enabling concepts are decentralization, self-organization, and autonomy. The design of key INM functions has been reported in the previous D-4.3 In-network management design.
This D4.4 document reports the results of the prototyping activity of WP4 in 4WARD. The objectives are twofold. First, it provides an analysis of potential exploitation scenarios of INM in the future Internet. Second, it reports the experience of an integrated implementation of the INM algorithms and provides a refinement of the INM design with detailed information flows.
Three scenarios have been identified as results of the joint activities between WP4 and the other Workpackages in 4WARD. The first scenario is about dynamic deployment of connectivity in emergency situations, where the interoperability function of WP2 is integrated with the INM real-time monitoring. The second scenario considers integration of INM cross- layer metrics with adaption function of the Generic Path considered in WP5: network coding is considered in our implementation as adaptation function. The third scenario applies INM function to virtual networks as considered in WP3. Here INM objectives are used to configure adaptive actions in case of congestion and therefore support operators’ business models. The document briefly discusses the benefits of the INM approach in these discussions, which can be summarized in three major items: reduction of integration effort, simplification of management operations and support for operator’s business.
The scenarios have implemented through a selected set of INM functions. To offer a unified view of the operations in INM, we describe first the organisation interface and we show then its configuration for objectives as well as controlling properties of the INM algorithms. This interface allows also for composition of INM algorithms and construction of workflows at local level (e.g. anomaly detection and triggering of adaptation function) and at domain level (e.g. construction of aggregated key performance indicators).
As experience of our implementation work, we provide details about specific INM algorithms: INM Runtime, Clustering, Anomaly Detection, Monitoring, cross-layer QoS. For these algorithms we describe a decomposition into functional modules and interaction diagrams. These instruments show how the functions designed can be implemented and mapped to the message flow in accordance to the INM interfaces.
This deliverable is one of the two final deliverables of WP4 and is complementary to D-4.5, which reports evaluation studies.
