Software Defined Networking (SDN), which decouples control plane and data plane, normally stores states on controllers to provide flexible programmability convenient management. However, recent studies have shown that such configuration may cause frequent unnecessary interactions between in some cases. For example, a DDoS detection installed controller needs fetch information from periodically,...

Service function chaining (SFC) is an indispensable technique for Internet service providers to efficiently manage their networks. However, SFC poses requirements of additional processing time functions (SFs) and increased routing owing detoured paths. In this paper, we introduce the use a programmable data plane (PDP) reduce times in SFC. We first classify existing PDP-empowered schemes analyz...

Software Defined Networking (SDN) is a new emerging network architecture, which allows, among other things, an efficient convergence between circuit switching and packet switching. However, this convergence imposes a trade-off between control plane load and data plane efficiency: while the SDN controller needs to establish one or more paths (circuits) that can deliver the required bandwidth wit...

This paper proposes an anomaly detection framework that utilizes key performance indicators (KPIs) and traffic measurements to identify in real-time misbehaving mobile devices that contribute to signaling overloads in cellular networks. The detection algorithm selects the devices to monitor and adjusts its own parameters based on KPIs, then computes various features from Internet traffic that c...

The forming limit diagram (FLD) is probably the most common representation of sheet metal formability and can be defined as the locus of the principal planar strains where failure is most likely to occur. Low carbon steel sheets have many applications in industries, especially in automotive parts, therefore it is necessary to study the formability of these steel sheets. In this paper, FLDs, wer...
