Abstract | |||||||||||||||
| Multicast communications have generated increasing interest during the past few years. This is due, in principle, to the obvious potential for improvement in the use of network resources: data is sent to a number of different recipients in just one transmission, instead of requiring the setup and the maintenance of distinct unicast connections. This means substantial savings both in terms of network load and in terms of server operation. However, multicast communications are generally more complicated and cause a number of difficult problems at different levels. In particular, the lack of multicast support in most Internet routers has made related technologies largely unavailable. Today, the widespread use of multicast-enabled applications and networks is possible and even likely. The reasons for this are twofold. On the one hand, the experience of the MBONE network (see, e.g., [21, 12], wwwmice. cs.ucl.ac.uk/multimedia, www.ipmulticast.com) has pushed the technology by demonstranting ... | |||||||||||||||
