Implementing Advanced Cisco® IP Multicast (MCAST) Version 2.0 provides students with in-depth knowledge about the IP multicast building blocks that make this IP service deployable. Bandwidth and processing power are wasted when data is replicated and sent from a source to potential receivers multiple times. With IP multicast and a sophisticated group of protocols, information is delivered with minimal effects on bandwidth and processor load. This IP service helps ensure simultaneous information delivery only to the people and the machines that require the information.
