Introduction
Taxonomy

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.
