....the QoS property from the multicast source to itself (mQoS) 4) The bounded flooding functions run at every network nodes. 5) Every node can use some mechanism to get the target address (multicast source or core router s address) of one multicast group, such as SDP(Session Directory Protocol)[11]. There are four types of messages involved in QMBF: 1) JOIN (taddr, gaddr, rQoS, aQoS, FPB) The join request message is originated by the a member and sent toward the target router requesting to find a feasible branch which can link the new member to the multicast group tree meeting the QoS ....

....be dynamic using some election process or it can be pre selected. The controller of the parent domain of a router is called as the parent controller. It is assumed that the address of the parent controller is either specified to the routers or can be obtained by inquiring the Session Directory [HaJ96]. The controller keeps track of the addresses of the controllers of its subdomains and the addresses of all the on tree routers within its domain. The controller only helps in locating the on tree routers and does not participate in the multicast tree. Therefore, the controller will not be a ....

When the 1 Future research is expected to extend the initial two tier design to that of N levels. 2 Other out of band schemes, like the Session Directory (SD) protocol [10] can be used for providing core,group mappings. receiver leaves the group, the branch between the leaf router and the egress node is torn down. Figure 1 presents a visualisation of the cascading join; wherein the receiver in Domain C issues an IGMP join to the leaf router, which in turn issues ....
