SD-networks are a new software-based networking approach where the control and data transmission mechanisms are separated. This separation alongside a software-based approach allows the network to become highly flexible and efficient to manage through centralized control features. A key reason behind SDNs flexibility is formed by the emphasis on using software which enables the paradigm to be tailored and customized to fit various different types of networks. This thesis finds that SDN can be applied to various applications such as data centers, internet of things networks, NFVs, and VANETs. These applications offer solutions for both large organizations such as cloud service providers through efficient control tools as well as individual end users through smart home network management. The results of this thesis also find that SDN suffers from multiple security issues that reside in each of the architectures layers. Many of the issues are caused by insufficient authentication and verification features. Additionally, results show that SDN can be prone to service denial attacks through flooding, injections and communication channel overloading. Finally, this thesis finds that a significant portion of existing literature focuses on mainly theoretical settings with models using primarily centralized models and de facto protocols. As a result, future body of research should be expanded by creating a wider range of research settings which are applied to real life environments.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by jyx lomake-julkaisija (jyx-julkaisija.group@korppi.jyu.fi) on 2024-12-05T20:01:28Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-12-05T20:01:28Z (GMT).
