Replica Placement and Request Routing

  • Magnus Karlsson
Part of the Web Information Systems Engineering and Internet Technologies Book Series book series (WISE, volume 2)


All content delivery networks must decide where to place its content and how to direct the clients to this content. This chapter provides an overview of state-of-the-art solution approaches in both of these areas. But, instead of giving a detailed description on each of the solutions, we provide a high-level overview and compare the approaches by their impact on the client-perceived performance and cost of the content delivery network. This way, we get a better understanding of the practical implications of applying these algorithms in content delivery networks. We end the chapter with a discussion on some open and interesting research challenges in this area.
