Abstract
| IP Multicasting breakthrough: Automatic Multicast
The primary goal of Automatic Multicast without explicit Tunnels (AMT) is to foster the deployment of native IP multicast by enabling a potentially large number of nodes to connect to the already present multicast infrastructure. The protocol specification can be deployed in a few strategically-placed network nodes and in user-installable software modules (pseudo device drivers and/or user-mode daemons) that reside underneath the socket API of end-nodes' operating systems.
This presentation will explain the benefits of IP multicast technology and describe how it is used within the broadcasting industry today. It will then explain the current challenges to wide scale IPTV distribution using IP multicast. Finally, it will explain how Automatic Multicast without explicit Tunnels (AMT) overcomes these challenges and briefly describe the status of this specification. |
