Learning Outcomes
Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu :
• Mendemonstrasikan program dengan menggunakan konsep Broadcast,
Multicast dan Unicast
2

Outline Materi
• Introduction
• Taxonomy
• IP Multicast
• Multicast Support in Winsock 2
3

UniCast
Unicast Data Transfer
4

MultiCast
• Components of a Multicast Session
– Control Plane
• Deals with the creation and management of a multicast session.
– Data Plane
• Transfer of data among multicast participants.
5

Taxonomy
• Rooted Control Plane
– There is one and only one root node. The rest are leaf nodes.
– The root node must remain present for the whole duration of the multicast session
– The root node creates a multicast session and controls the addition and removal of leaf nodes.
– Example: ATM (Asynchronous Transfer Mode)
6

Taxonomy
• Rooted Control Plane
7

Taxonomy
• Non-Rooted Control Plane
– There is no root node. All node are leaf nodes.
– The network can perform the role of the root node.
– Nodes join and leave a multicast session through out-of-band methods.
– Example: IP Multicast, H.320 video conferencing.
8

Taxonomy
• Non-Rooted Control Plane
9

Taxonomy
• Rooted Data Plane
– There is one and only one root node. The rest are leaf nodes.
– Data exchange can only occur between a leaf node and the root node. Not leaf node to leaf node data exchange is allowed.
– The root node will distribute data to all leaf nodes.
– Example: ST-II (Internet Stream Protocol
Version 2).
10

Taxonomy
• Rooted Data Plane
11

Taxonomy
• Non-Rooted Data Plane
– There is no root node. All node are leaf nodes.
– A node’s transmission is delivered to all other nodes.
– A node receives data from all other nodes.
– Example: IP Multicast.
