Self-Management

One of the main features of Next Generation Networks is the panoply of wired and wireless access technologies, transport protocols, network devices, applications and users’ requirements. Thus, in order to fulfill the demand for constant connectivity and the provision of a ubiquitous service, it is necessary to overcome the heterogeneity of future networking environments. In this sense, the future of telecommunications points to intelligent networks able to capitalize information about users and the network itself, in order to offer personalized services while, simultaneously, optimizing rich-media content distribution. This new paradigm is of particular interest of Internet Service Providers (ISPs), since defining new types of services that take advantage of heterogeneity is an added value regarding customer attraction and satisfaction.

Moreover, the increasing demand for group-based communications, such as IPTV, multimedia streaming (on-line gaming, video, music) and file sharing has been raising the need for more efficient solutions that may scale and adapt these services. The knowledge about user context information becomes imperative for operators, aiming at providing enhanced customer experience. Despite the potentialities, context driven architectures adds increased complexity and dynamics.

This research area is very broad and encompasses several sub-areas:

  • Hierarchical network control for multicast networks: this work has started in the European FP7 ICT-C-Cast Project, and has been continued in the Internal IT GEN-CAN and the FCT MuMoMgt and FCT GTI-CANE Projects.
  • Network coding as a source of context in the self-management and control of networks: this work is being pursued in the FCT GTI-CANE Project.
  • Self-management in the integration of core and mesh networks: this work is being pursued in the FCT MuMoMgt Project.
  • Quality of Experience-based scheduling and routing though artificial intelligence concepts, such as reinforcement learning: this work is being pursued in the FCT UBIQUIMESH Project.
  • Decentralized network resources control performed through the network edges: this work has started in the European FP7 ICT-C-Cast Project, and has been continued in the Internal IT GEN-CAN and the FCT MuMoMgt and FCT GTI-CANE Projects.
  • Distributed Self-Management and Decisions – Mechanisms for communication and decision in In Network Management (INM), where the management is performed in a distributed way in the network nodes, requiring the knowledge of nodes and its information in the network, communication approach for the dissemination of node’s information, and probabilistic and distributed decision mechanisms in the nodes to provide collaborative decisions in the network: this work has started in the European FP7 ICT-4WARD Project, and has been continued in the FCT UBIQUIMESH Project and in the Innovation Program Project SELF from Portugal Telecom Inovação.
