Architecture for Delivery of Virtualized Network Functions

The main aim of this dissertation is the creation of a new architecture that interconnects several domains. The network elements of these domains are controlled by Software Defined Networking technology (SDN), and these domains also contain virtualized network functions (NFV), so the term SDN/NFV domain is used in the work further. The SDN/NFV domain combines all the benefits that both technologies bring, creating a fully automated domain to deliver network functions in virtualized form. These SDN/NFV domains can be implemented in a different way. Currently there are existing solutions from Cisco, Juniper, HPE, IBM, Metaswitch and many others containing various SDN controllers, various other applications helping to manage the SDN/NFV domain. The result of the research is a new architecture for interconnection and transparent management of different SDN/NFV domains. The proposed solution has been successfully verified using the Petri Color Mathematical Modeling Tool.
