In , we proposed a Content Name System (CNS) discovery service, extending the current TCP/IP hourglass Internet architecture, that provides a new network aware content discovery service. Contents are addressed using “hypernames", whose rich syntax allow to specify hosts, PKI, fingerprint and optional logical attributes (tags) attached to the content name, such as e.g. mutable vs. immutable contents, digital signatures, owner, availability, price, etc. The CNS behavior and architecture is, partly, inspired by the Domain Name Service (DNS), and whose discovery process logic uses the Border Gateway Protocol (BGP) information allowing Internet to route between different Autonomous Systems (AS). The service registers and discovers object names in each Autonomous System (AS), and the content discovery process is inspired to the so called “valley-free” property. In the routing among different ASes (i.e., the BGP protocol) this is a property that avoids unjustified AS transit costs.
