We propose a design to aid experimentation with SDN architectures using legacy network equipment. We implement a portion of the design on an FPGA and evaluate throughput and latency. Results indicate viability for testbed and research environments, especially with proposed additions to further reduce latency in broadcast-and multicast-heavy traffic.
The current study examines the role of psycho-social individual characteristics, social media motives, and social media use as predictors of interpersonal communication competence (ICC). Applying the uses and gratifications theoretical framework, this research seeks to explore the potential effects of social media use related to the second digital generation (2DG), or those born after 1990. A cross-sectional study design, surveying 373 college students ages 18-24 years, found that offline social capital, interpersonal interaction, and social activity were direct, positive predictors of ICC. Social media motives and use contributed a small but significant portion of explained variance in the model, above and beyond effects of psycho-social characteristics. Specifically, members of the 2DG who use social media to compensate for offline loneliness, as well as those who were more dependent on social media to fulfill a variety of needs reported lower ICC. Limitations and directions for future research are also offered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
