An exposed approach in computer service architectureis one that offers client software a primitive servicewhose semantics are closely based on the underlyingphysical infrastructure. The exposed approach relies onthe client to build higher-level services, with moreabstract semantics, out of such primitive tools usingsophisticated compilation or run-time algorithms.Current approaches to reliable multicast focus onencapsulated algorithms for efficient retransmission ofdatagrams to sets of receivers that require them. Theseapproaches include augmenting the primary multicastdata channel with direct TCP connections or withsecondary multicast channels for retransmissions, andon the possibility of retransmissions originating fromnodes in the middle of the network. In this paper weoffer an exposed approach to multicast that uses anunderlying Logistical Networking infrastructure thatmakes possible the implementation of any of the currentretransmission algorithms, as well as new strategies yetto be devised.
