Maufer and Chuck Semeria}, title = {{Introduction to IP Multicast Routing}}, pagetotal = 60, year = 1997, month = oct, day = 28, abstract = {The first part of this paper describes the benefits of multicasting, the MBone, Class D addressing, and the operation of the Internet Group Management Protocol (IGMP). The second section explores a number of different techniques that may potentially be employed by multicast routing protocols: o Flooding o Spanning Trees o Reverse Path Broadcasting (RPB) o Truncated Reverse Path Broadcasting (TRPB) o Reverse Path Multicasting (RPM) o ''Shared-Tree'' Techniques The third part contains the main body of the paper. It describes how the previous techniques are implemented in multicast routing protocols available today (or under development). o Distance Vector Multicast Routing Protocol (DVMRP) o Multicast Extensions to OSPF (MOSPF) o Protocol-Independent Multicast - Dense Mode (PIM-DM) o Protocol-Independent Multicast - Sparse Mode (PIM-SM) o Core-Based Trees (CBT)}, }
