....error recovery implicitly by relaxing the target presentation time to that of the slowest client to secure the time for retransmission. The client can not do a multicast feedback, since the neighboring routers for each client are configured by IGMPv3 (Internet Group Management Protocol, version 3) [19] protocol to filter a source in the SSM. Instead, each client uses a customized unicast RTCP receiver report (RR) while the server multicasts a RTCP sender report (SR) to deliver a control message [15] The most important component of the proposed framework is the adaptive playout control, that ....

Also, the client can not do multicast feedback, since the neighboring router for each client is configured by IGMPv3 [8] protocol to filter a source in For the sake of simplicity, neither layered encoding nor multicast congestion (or flow) control is integrated at this stage. The allowed range depends on the latency requirement of application and the capabilities of clients. With the time synchronization ....

....one another without using an intermediate server. Multicast Transmission Security Several aspects of multicast transmission, as it is implemented in the Internet, lead to increased vulnerabilities [15] In general, anyone can join a multicast group because standard Internet multicast protocols [16, 17] distribute the task of group management among the receivers rather than placing the entire burden upon the sender. Receivers simply send a subscription message to their local multicast router, and traffic for that group will be forwarded to them. FIGURE 4. Unicast transmission from a single ....

The mcontrol protocol is not standardized. It would be better to use an standard protocol. 2. 3 IGMPv3 When IGMPv3[13] first appeared, our problem related to using an standard protocol for informing the local attached routers about the filters to apply disappeared. In fact, the new version of IGMP now allows for source filtering. That s to say, when a host joins a multicast group, it can tell the router to ....

When a router is part of a multicast tree, it will receive multicast data and forward them to group members in its subnet. In the rest of ....

The mechanism provided for doing this is the Internet Group Membership Protocol(IGMP) [3]. A host uses this protocol to notify the routing system that it should deliver packets for a particular multicast group to this host. In the current model, any host can use IGMP to become a member of any IP multicast group causing eavesdropping or theft of service. The common method used to ....

....joining and leaving a group asynchronously and without the knowledge of the source(s) Multicast packets are addressed to a group address. Receivers wishing to join the multicast group simply listen to the group s address and inform a local designated router of this via the IGMP protocol [1, 2, 3]. A multicast routing protocol operating within the network ensures the delivery of multicast packets to joining receivers. Multicast scoping is one of the methods by which the propagation of multicast packets is controlled in such a dynamic environment. A typical scoping technique utilized in ....

We assume that we have a multicast source at host H0 and 2 A more general form of this allows the receiver to specify different threshold values for each source in a source based routing scenario.

Receivers can dynamically join and leave this group using IGMP (Internet Group Management Protocol) 1] 2] [3]. Packets are forwarded to the multicast group by a multicast routing protocol, e.g. PIM, DVMRP [4] 5] 6] The propagation of these multicast packets can be controlled by multicast scoping. The two methods currently being used to perform multicast scoping are: TTL scoping and administrative ....
