Streaming Media Delivery in Higher Education

The large amount of bandwidth and other resources required to deliver streaming media limits the number of concurrent users. We propose a virtual active network (VAN) architecture for streaming media data delivery over wide area networks. In the proposed architecture, cooperating proxies support multiplexing and delivery of live streaming media. The hierarchical delivery structure is dynamically adjusted based on user population distribution, usage patterns, and network conditions. The proposed system architecture provides (1) reliable and high quality live streaming media delivery; (2) lower server resource requirements at the content provider sites; (3) reduced inter-ISP traffic; (4) application level routing for rapid deployment; and (5) cost-effective media data delivery. To deal with one characteristics of live broadcasting events, burst traffic at the beginning of the events, our system features a unique function that dynamically clusters multiple proxy servers to form a server farm to handle a large number of user login events when needed. Experimental results show that the proposed VAN architecture consistently delivers reliable live data streams using resources within 10 percent of the theoretically possible lower bound. The experimental results also show the effectiveness of our load balance algorithms to handle various user patterns, server capacity, and network congestion events.

Digital Stories

Teachers in higher education interested in making use of streaming media can access more sources of video than ever before: news sites, popular media sites, YouTube, and Cornell eClips, the world’s largest collection of short videos for educators (more than 14,000). Miller (2008) provides an impressive list of sources, along with a discussion of pedagogical rationale for using rich media. However, while supplies are numerous and demand from students is high, many educators lack the experience to integrate rich media effectively in their teaching. In this chapter, the author draws from her experience of building a library of digital video since the mid-90s with her eClips team and using it in the classroom. The chapter will focus on: 1) strategies and practical tips for using video inside and outside the classroom to engage learners and respond to short attention spans and 2) guidelines for educators who wish to create their own rich media collections because they need content that has a very specific focus and/or mirrors their learner population more appropriately in terms of demographics.
