The novel network architectures supported innovative...
CDNs are today the most scalable way of distributing content. Thanks to CDN interconnection even smaller operators can achieve global footprint. The main cost of this operation is the added latency because requests have to traverse multiple autonomous networks. The work in this article was able to quantify the real impact of this phenomenon and to point to its drawbacks and potential solutions.

Since this process takes a long time IPv6 and IPv4 networks coexist in Internet and some transition mechanisms are needed to ensure their interconnectivity. Several mechanisms came to life based on tunneling or translation...
The use of modern ICT technology has revolutionized the way that universities perform their teaching and learning role. Recent high profile MOOCs have shown that e-learning approaches can attract large numbers of students to study subjects such as electronic circuits. However, high dropout rates and concerns about quality mean that it is unlikely that e-learning techniques alone can meet the industrial...
