The SSM service model draws on a variety of prior work on alternative approaches to IP multicast, including the EXPRESS multicast model of Holbrook and Cheriton [EXPRESS], Green's [SMRP], and the Simple Multicast proposal of Perlman, et al. [SIMPLE]. We would also like to thank Jon Postel and David Cheriton for their support in reassigning the 232/8 address range to SSM. Brian Haberman contributed to the IPv6 portion of this document. Thanks to Pekka Savola for a careful review.
