DDoS mitigation schemes are increasingly becoming relevant in the Internet. The main hurdle faced by such schemes is the “nearly indistinguishable” line between malicious traffic and genuine traffic. It is best tackled with a paradigm shift in connection handling by attesting the path. We therefore propose the scheme called “Path Attestation Scheme” coupled with a metric called “Confidence Index”...
Filtering out a subset of learning resources from a large repository to meet the requirements of a particular learning situation is a difficult task, due to the high degree of subjectivity in requirements and the combinatorial complexity of matching. In this paper, we propose a two stage approach with feedback. First, a pair of metrics quantifies the match between a learning resource and a learner...
Composing learning material for online education and ensuring quality of delivery (low latency and high bandwidth) is a challenge to researchers in e-learning. The problem is compounded when the computing platforms are heterogeneous. Besides, e-learning as an application presents a highly fluctuating load to the underlying IP Multimedia Subsystem.
