| Περίληψη: | Key objectives of network technologies are their overall management and creation of new services. But networks are generally heterogeneous and this creates a problem in their flexibility and integration of new services. Current solutions address the problem piecemeal, without a common framework. The aim of the PhD dissertation is to propose a common framework for resource control and management of a network model alongside with auxiliary and automatic functions to support implementation of new services in open programmable network. This dissertation laid the requirements of the model that would be required and chosen IETF’s ForCES from other framework standards. The dissertation contributed to the ForCES model in multiple ways. It identified gaps and enhanced the current model, made the comparison with similar frameworks and conceptually extended the standard in the resource management plane. Libraries also were proposed and developed, using the model, related to high availability, parallelization and subsidiary mechanisms for installation and activation of new entities. Using this model, the building blocks of a common framework were laid and the architectural structure of open networks was described. Furthermore, this dissertation proposed the conceptual and architectural enhancement of the SDN architecture to include the management plane and the operational plane within devices. With regards to the architecture of NFV, this dissertation proposed to extend the architecture by integrating the interface between the EMS and the NFV using the proposed framework. With regards to auxiliary and automatic features a Domain Specific Language was implemented within this dissertation. The DSL allowed the user to describe the model and then automatically converted that into pieces of code stubs that had implementation of the ForCES standard. The user would only have to fill the required functionality. Finally an original implementation was developed as proof of concept on the LTE/EPC. This dissertation addressed the problems of disproportionate signaling growth and long-distance portions of the EPC architecture using the proposed framework and implemented the management part of the GTP tunneling protocol. In conclusion, the use of a framework for overall management of the entire life cycle of network resources is possible using the proposed advanced ForCES framework.
