One of the most relevant problem for an Internet Service Provider is the large bandwidth usage on international
links, mainly due to peer-to-peer applications adopted for file-sharing. The Collaborative Locality-aware Overlay
SERvice (CLOSER) technology has been recently proposed to solve this issue by properly modifying the behavior of
peer-to-peer application. The technology is also covered in two recent patent applications. This paper presents possible
design guidelines to actually implement CLOSER in a DHT-based peer-to-peer system and describe a real implementation
based on the popular aMule application.
