Mesh-First Tree Networks

The animated TECHTip Tutorial is available here.

Mesh-First Tree Networks are created on the basis that a mesh (interconnected) network is formed before a routing protocol is determined. Then Source-Rooted Trees are selected based on the routing protocol such as DVMRP [Distance Vector Multicast Routing Protocol]. DV [Distance Vector] routing protocols maintain a routing table which consists of destination nodes, corresponding costs and next hops (routers).

Routing Tables analyze the routes and determine the SPF [Shortest Path First]. Then for multicast routing, RPF [Reverse Path Forwarding] is used to determine SRT [Source Rooted Trees] for content distribution.

Source trees are the source (root) of the multicast tree whose branches form a spanning tree throughout the network to the receivers. As the tree uses the shortest path, it is often called SPT [Shortest Path Tree] from which algorithms (rules-of-thumb) are developed to move data packets (traffic) farther and faster.
