International Journal of Network Management

Modern computer networks and communication systems are increasing in size, scope, and heterogeneity. The promise of a single end-to-end technology has not been realized and likely never will occur. The decreasing cost of bandwidth is increasing the possible applications of computer networks and communication systems to entirely new domains. Problems in integrating heterogeneous wired and wireless technologies, ensuring security and quality of service, and reliably operating large-scale systems including the inclusion of cloud computing have all emerged as important topics.

    This paper evaluates the cost efficiency of SDN-optimized in-network caching compared with data center caching for a Finnish LTE reference network. Network simulations are used as input for the cost model, and the results show that in-network caching compared with data center caching reduces network load by 45% and gateway load by 6%. The cost modeling indicates that in-network caching reduces network-related CAPEX by 1.53% and OPEX by 0.49% compared with caching only in data centers.

    In this paper, we reveal multiple vulnerabilities in popular network operating systems (NOS), which are also known as software-defined networking controllers. To tackle this problem, our sandbox-based system restricts access to critical operations and, thereby, counteracts the root cause of these vulnerabilities. For our proposal, we provide two proof-of-concept implementations: one for the industries leading open-source NOS called OpenDaylight and another one for the HP controller, which serves as foundation for the world's first software-defined networking App Store.

  5. Cost-based placement of vDPI functions in NFV infrastructures (pages 490–506)

    For a network operator, deploying a set of vDPIs over the NFV-enabled network is a matter of finding the appropriate placement that meets the traffic management or cyber-security targets and operational cost constraints. In this work, we formulate the vDPI placement problem as a cost minimization problem and devise a centrality-based greedy algorithm. We assess its validity by comparing it with the integer linear program optimal solution on a real dataset and on larger random graphs.
