This specification defines a multicast routing algorithm for multicast groups that are densely distributed across an internet. The protocol is unicast routing protocol independent. It is based on ESL sparse-mode [Estrin93] and employs the same packet formats. This protocol is called dense-mode ESL. The design is based largely on foundational work by Deering [Deering91].
