Multicast routing protocols are evolved in core based approach for better performance of its operations in distributed networks. The structure and location of routing tree is dominant determinant on the performance of protocol in multicast applications. In group applications that involve instant interaction in participations including audio visual conferencing, the protocol becomes sensitive for multipoint communication under multiple metrics to fulfill the demands of quality of services. This process of tree construction seems crucial for protocols operations because lack of coreselection can degrade the efficiency of protocol.

Multicasting protocol enables a collection of multiple routers to construct distribution trees. There is list of five multicast protocols that help you to comprehend their functions.

DVMRP- The first multicast routing protocols are hampered with multiple limitations that make this method unattractive for wide range of application. DVMRP is a dense mode protocol that uses prune and implicit method to deliver traffic. DVRMP make use source based distribution trees in form of S G.

MOSPF-It extends OSPF for multicasting in dense mode. MOSFP shows explicit join method to flood entire domain in multicast traffic from source to destination. It likes DVMRP uses source destination trees in form of S.G.

PIM-DM-It operates in dense mode but it is different from PIM spare mode. Unlike MOSPF and DVRMP, PIM-DM helps router to use unicast routing protocol and executes the process of RPF checks with the use of unicast routing table. It contains PIM-DM in an implicit join message that helps routers to use prune method and flood to deliver traffic anywhere. PIM-DIM also uses source based distribution tress as other multicasting protocols do.

PIM-SM- It helps routers to use unitcast routing table and performs the checks of RPF during unicast table. It also contains explicit message to determine the location of receivers and send messages to their neighbors. It uses RP routers in form of initial source of multicast group traffic and construct trees in form of G. PIM-SM also moves to source based tree if routing path is shorter than RP for multicast traffic group.

CBT- it contains all the characteristics of PIM-SM like explicit join, sparse mode and shared G trees but it is efficient to find sourced than PIM-SM.
