RFC 2201:
Title: Core Based Trees (CBT) Multicast Routing
Architecture
Author: A. Ballardie
Category: Experimental
Date: September 1997

Pages: 15

CBT is a multicast routing architecture that builds a single delivery
tree per group which is shared by all of the group's senders and
receivers. Most multicast algorithms build one multicast tree per
sender (subnetwork), the tree being rooted at the sender's subnetwork.
The primary advantage of the shared tree approach is that it typically
offers more favourable scaling characteristics than all other
multicast algorithms.
The CBT protocol [1] is a network layer multicast routing protocol
that builds and maintains a shared delivery tree for a multicast
group. The sending and receiving of multicast data by hosts on a
subnetwork conforms to the traditional IP multicast service model
[2].
