The current Internet includes a large number of distributed services. In order to guarantee the QoS of the communications in these services, a client has to select a close-by server with enough available resources. To achieve this objective, in this book, we propose a simple and practical solution for Dynamic and Location Aware Server Discovery based on a Distributed Hash Table (DHT). In more detail, the solution works as follows. The servers offering a given service S form a DHT. In addition, they register their location (topological and/or geographical) information in the DHT. Each client using the service S is connected to at least one server from the DHT. Eventually, a given client C realizes that it is connected to a server providing a bad QoS, then, it queries the DHT in order to find an appropriate server (i.e. a close-by server with enough available resources). We define 11 design criteria, and compare our solution to the Related Work based on them. We show that our solution...
