There is tremendous confusion among practitioners regarding the relationship between various potential online revenue streams and the performance of a firm's online efforts. Such questions are of particular interest to firms that provide information goods, due both to the unique characteristics of such goods and the fact that such products are increasingly offered free by online providers. Usin...

The Internet has become a multi-purpose network capable of providing many services to a variety of geographies and population. Content delivery of digital content covers many possibilities from music and video to published papers and e-Books, and also wide ranging services and applications. This paper describes the challenges of providing the infrastructure required to make digital content deli...

In recent years, there has been a rising concern about the policy of major search engines. The concern comes from search bias, which refers to the ranking of the results of a keyword search on the basis of some other principle than the sheer relevance. This search bias is also named search non-neutrality. In this paper, we analyze one non-neutral behavior, that is, a behavior that results in a ...

In many countries, Next Generation Access networks (NGA) deployment and penetration rate proceed at a slower pace than expected. We argue that an ex ante contractual arrangement among access Internet Service Providers (ISPs) and Content Providers (CPs), which builds on the complementarity between infrastructure and content, can promote the roll out of NGA. Di erent from co-investment of ISPs, a...

For more than 40 years, community health centers (CHCs) have provided primary care and behavioral and mental health services in medically underserved communities, regardless of a patient's ability to pay. In 2001, the government launched the Federal Health Center Growth Initiative, providing funds over 5 years to increase by 60% the number of patients served in 1,200 communities. As the number ...

In-network caching is an important solution for content offloading from content service providers. However despite a rather high maturation in the definition of caching techniques, minor attention has been given to the strategic interaction among the multiple content providers. Situations involving multiple content providers (CPs) and one Internet Service Provider (ISP) having to give them acce...

Knowing the detailed topology of the Internet at the Autonomous System (AS) level is extremely valuable for both researchers and industry when making network policies. Although there are many measurement projects and databases that provide this information, such as ARK, RETRO, ONO and PeeringDB, they only offer a partial view for analyzing end-to-end Internet routing paths and they do not focus...

In this thesis I will show that, by leveraging efficient data structures and algorithms for indexing and secure computation, we can create practical systems for anonymous and private search, communication, and content distribution. I will improve and extend existing work in private search, which only addresses the problem where a client stores his own data encrypted on a server and wishes to be...
