00:00 - CONTENT of this CHAPTER 00:18 - Motivation 01:25 - Inefficient implementation of group communication 03:11 - Efficient implementation of group communication: Multicast 04:58 - IP Multicasting is an approach to transmit IP datagrams to a group of IP hosts 06:43 - Further properties of IP Multicasting 09:21 - There are two types of multicast 10:54 - We need a group subscription mechanism to reduce broadcasts 12:23 - Subscribing locally to a multicast group 15:19 - IPv4 vs. IPv6 15:45 - Internet Group Management Protocol (IGMP) 19:29 - The objective of multicast routing is creation of a distribution tree from source(s) to receiver(s) 20:17 - The objective of multicast routing is creation of a distribution tree from source(s) to receiver(s) 21:21 - The objective of multicast routing is creation of a distribution tree from source(s) to receiver(s) 22:32 - The objective of multicast routing is creation of a distribution tree from source(s) to receiver(s) 24:15 - The objective of multicast routing is creation of a distribution tree from source(s) to receiver(s) 26:10 - The objective of multicast routing is creation of a distribution tree from source(s) to receiver(s) 27:46 - Example of Flooding & Pruning: DVMRP 28:39 - Use a rendezvous point: Protocol Independent Multicast (PIM) 30:58 - PIM SM is suitable for widely distributed groups 34:02 - PIM SM Receiver Tree Join 35:06 - PIM SM Sender Registration via Rendezvous Point 36:19 - PIM SM Sender Registration: Switch to multicast tree between RP and source 37:04 - Source specific and shared tress 38:03 - PIM SM Short Cut: DR Router of Receiver joins source tree 38:59 - PIM SM Short Cut: Prune shared tree from receiver to RP 39:38 - PIM SM Short Cut: Tree from source to RP not needed 39:56 - PIM SM Short Cut: Prune source tree from source to RP 40:22 - Optimal source tree achieved 41:16 - Recap group management and routing 42:56 - Unicast and multicast forwarding are fundamentally different 44:37 - Multicast API 45:04 - Multicast in the real world 46:39 - Network Layer Summary 1 48:14 - Network Layer Summary 2 49:17 - Questions & Tasks
