These proposals can be roughly categorized as being either infrastructure-based, with the multicast functionality provided by designated network nodes, or host-based, with the multicast functionality provided by the members of the multicast group itself.
These proposals can be categorized as either infrastructure-based, with the multicast functionality provided by specialized network nodes, or host-based, with the multicast functionality provided by the members of the multicast group itself.
A different approach, overlay multicast, moves multicast functionality to end hosts, thereby removing the dependency on router deployment, albeit at the cost of noticeable performance penalty compared to IP multicast.
"I'm big on functionality and durability.
For the MN, no specific mobility or other multicast related functionalities are required.
The UM design consists of three major components: an overlay multicast protocol (HMTP) for inter-island routing, an intra-island multicast management protocol (HGMP) to glue overlay multicast and native IP multicast together, and a daemon program to implement the functionality at hosts.
At the Bundle layer, functionalities of storing-carrying-forwarding are considered and employed for multicast and anycast [25 27].
We consider different performance metrics and multicast algorithms for such a multicast facility, and develop guidelines for its design under various conditions.
In traditional papers, the multimedia server makes multicast groups and is in charge of multicast transmission.
This work assumes that the multicast tree is generated by the multicast source and the path from multicast source to destination node is known.
