Firewall as a service in SDN OpenFlow network
2015
Protecting publicly available servers in internet today is a serious challenge, especially when encountering Distributed denial-of-service (DDoS) attacks. In traditional internet, there is narrow scope of choices one can take when ingress traffic overloads physical connection limits. This paper proposes Firewall as a service in internet service providers (ISP) networks allowing end users to request and install match-action rules in ISPs edge routers. In proposed scenario, ISP runs Software Defined Networking environment where control plane is separated from data plane utilizing OpenFlow protocol and ONOS controller. For interaction between end-users and SDN Controller author defines an Appl…
Fuzzy topology discovery protocol for SDN-based wireless sensor networks
2017
Abstract The growing trend in pervasive systems forces traditional wireless sensor networks to deal with new challenges, such as dynamic application requirements and heterogeneous networks. One of the latest paradigms in this area is software defined wireless sensor network. According to the paradigm, the networks take care of managing topological information and forwarding decisions using a bipartite architecture in which a control plane decides the forwarding policies and the data plane (i.e. ordinary sensor nodes) executes them. Unfortunately, in highly dynamic networks, this approach generates an overhead of control packet exchange between the ordinary nodes and the control plane, that …
