In this chapter we present three different methods by which our redirector can select replicas for a given client. They include a static name-to-address policy, a ``round-robin'' address selection policy, and a proximity policy based on AS-path length metric. This chapter is organized as follows. We start with presenting a general policy model and the theoretical foundations of the two first policies. Then, we discuss the most advanced, the AS-path-based one. Finally, we give implementation details for all policies.
