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
