'''Core- Basedbased Treestrees''' ('''CBT''') is a proposal for making [[IP [[Multicast]] [[scale (computing)|scalable]] by constructing a [[tree structure|tree]] of [[ Router (computing)|router]]s. It was first proposed in a paper by Ballardie, Francis, and Crowcroft. What differentiates it from other schemes for multicasting is that the routing tree comprises multiple "cores" ( a.k.a.also known as "centres"). The locations of the core routers are statically configured. Other routers are added by growing "branches" of a tree, comprising a chain of routers, from the core routers out towards the routers directly adjacent to the multicast group members. ▼<!-- Please do not remove or change this AfD message until the issue is settled -->
