Sammanfattning
Internet is a disruptive technology that has changed the way of we see the world now. Since its origin in the 60’s it has been spread to over single field in our quotidian life. Nowadays internet usage accounts for 2% of the global energy usage, but is expected that it growth will be increasing and increasing within next years, as the number of users increases by the appearance of different mobile devices. It is also remarkable the usage of the internet; on the last years and encouraged by the increasing of the broadband services, multimedia content delivery is the most common usage of the internet. The concept of energy efficiency has become more popular on the last years, but the fact is that besides the widespread of the ecological issues, there is also an important economical part behind this since electricity has a price. Since all models and evaluation of the different ways of optimizing energy efficiency for digital media distribution are complex and depend on different variables, with this thesis we pretend to shed some light on which are the most common used architectures: CDN (Chapter 2), P2P (Chapter 3), and CCN (Chapter 4). In chapter 5 I consider different solutions and procedures for delivering media content among the network that don’t belong specifically in aforementioned structures. In chapter 6 I apply my acquired knowledge to a particular case of study where I analyze which is the best oriented solution in terms of energy efficiency. Chapter 7 is for conclusions and future work. After deeply analyzing which is the state of the art and new trends with its pros and its cons, I will conclude that there is no standard and directly applicable solution which would be valid for all models.
