[Everything needs to change, so everything can stay the same, From “The Leopard” by Giuseppe Tomasi di Lampedusa] Internet in recent years has become a huge set of channels for content distribution. And this has highlighted limits and inefficiencies of the current protocol suite originally designed for host-to-host communication. This paper joins the research efforts addressed by the new Internet challenges by proposing LogNet, a conservative extension of the current TCP/IP hourglass Internet architecture, that provides a new network aware Content Discovery Service. Contents are referred via the new notion of HyperNames (HN), whose rich syntax allow to specify, hosts, pki, fingerprint and a large list of optional logical attributes (tags) attached to the content name, such as mutable vs immutable contents, digital signatures, ownership, availability, price, etc. HyperNames are in part human-readable and in part machine-readable and only in the latter case self-certifying. Publication and discovery of HN is achieved using the new distributed service Content Name System (CNS) with related protocol, whose behavior and architecture is, partly, inspired by the DNS, and whose “routing logic” uses the BGP inter domain routing information. The core of CNS is the HyperName Lookup Algorithm (HLA) which “tunes” content discovery of being network aware, by exploiting the Autonomous System (AS) relationships. In partic- ular, the HLA starts the content discovery process in the local AS (i.e., where the query starts), and in case of negative answer, propagate the query by accounting for the AS-to-AS relationships (i.e., peering, provider-to-customer, customer-to-provider). After discovered the owner(s) or the purveyor(s) of the content we are looking for, the latter can be retrieved using common transfer protocols (centralized or distributed), since the actors of this transfer are chosen in a network aware fashion (i.e., as close as possible one to each other).
