“…Internet Group Management Protocol (IGMP) [5] handles communication between client and edge router. According to [6], current implementation of intra-domain routing is based on Distance Vector Multicast Routing Protocol (DVMRP) [7], Multicast Extensions to OSPF (MOSPF) [8], and Protocol-Independent Multicast Sparse Mode (PIM-SM) [9], while the inter-domain routing is based on Multicast Source Discovery Protocol (MSDP) [10] or Multicast Border Gateway Protocol (MBGP) [11].…”

In this paper, we propose a protocol for multicast communication called Multicast Datagram Transfer Protocol (MDTP) to provide multicast for video broadcasting service on the Internet. MDTP is a oneto-many multicast communication protocol, which is constructed based on IPv4 unicast protocol by utilizing IP Router Alert Option, and it uses unicast addressing and unicast routing protocol. A mechanism is presented to allow a router to remove identical video stream, to duplicate a video stream, and to forward each copy of the duplicated video stream to its destinations. Ordinary IP routers that do not support MDTP will treat the MDTP packets as normal unicast packets. Hence, gradual deployment is possible without tunneling technique. With a delegation mechanism, MDTP router is also able to handle request from clients, and serve the requested video stream. The simulation results show that the average bandwidth usage of MDTP is close to the average bandwidth usage of IP multicast. MDTP also has greater efficiency than XCAST, and its efficiency becomes significant for a large number of clients.

Abstract. There is no effective method to support IP level Internet wide multisource multicast sessions, that can be easily used from almost every ISP There are several protocols implementing the necessary functionality, but the penetration of them is really low recently. The most obvious work all-round is using SSM -Source Specific Multicasting, in which, the IP multicast session is identified by the multicast group address and the source's unicast IP address. SSM allows using all the SSM address range for every source IP addresses and limits the address allocation problem inside the host of the source; however, its significant drawback is that the SSM has no native support to create multicast sessions with more than one source; it uses separate source specific distribution trees for every single source therefore it needs more resources on the router side. The alternative solution for supporting multisource multicast session is the ASM -Any Source Multicasting. However, its significant drawback is the lack of Internet wide dynamic address allocation. To address the recent problems of the Internet wide multisource multicast session a novel IP multicast service model, the Responsible Source Multicasting -RSM is introduced in this paper. RSM uses shared distribution trees like ASM; however, builds a reverse path tree towards an appropriate well-known unicast IP address like SSM. The paper demonstrates that this novel multicast routing protocol handles Internet wide multisource multicast sessions. The paper also shortly presents the DAMA -Dynamic Address Allocation of Multicast Addresses protocol for dynamic multicast IP address allocation, which works in a strong collaboration with the RSM.
