Having gained momentum from its promise of centralized control over distributed network architectures at bargain costs, software-defined Networking (SDN) is an ever-increasing topic of research. SDN offers a simplified means to dynamically control multiple simple switches via a single controller program, which contrasts with current network infrastructures where individual network operators manage...
We present Ryuretic as a modular, programming framework for SDN application development. Ryuretic draws its inspiration from Pyretic, which already offers powerful, modular abstractions for network operators; however, Ryuretic also builds on Ryu's greater variety of packet match fields and its access to advanced OpenFlow protocols. This framework allows programmers to create new, extensible, and more...
Insider threats are a growing concern for industry, government, and campus networks. Yet, vulnerabilities inherent in Address Resolution Protocol (ARP) are exploitable by insiders seeking to launch sophisticated attacks on local area networks (LANs). Such attacks, initialized through ARP spoofing, include denial of service, server redirect, and man-in-the-middle attacks. Unfortunately, the current...
In this paper, the primary objective is to discuss the details of scalable methods for distributing certificate revocation lists and other large files using vehicle-to-vehicle and vehicle-to-infrastructure communications while taking advantage of the multi-channel operations in IEEE 1609.4. We also discuss the results from a simulation study using the ns-3 network simulator to closely replicate the...
