A tree topology, or star-bus topology, is a hybrid network topology in which star networks are interconnected via bus networks. [ 1 ] [ 2 ] Tree networks are hierarchical, and each node can have an arbitrary number of child nodes.
The fat tree topology can offer up to 1:1 oversubscription ratio and full bisection bandwidth, [3] depending on each rack's total bandwidth versus the bandwidth available at the tree's highest levels. Higher tree branches are typically oversubscribed to their lower branches by a ratio of 1:5, with the problem compounding at the highest tree ...
A tree topology (a.k.a. hierarchical topology) can be viewed as a collection of star networks arranged in a hierarchy. This tree structure has individual peripheral nodes (e.g. leaves) which are required to transmit to and receive from one other node only and are not required to act as repeaters or regenerators. Unlike the star network, the ...
The architecture uses commodity switches that are cheaper and more power-efficient than high-end modular data center switches. This topology is actually a special instance of a Clos network, rather than a fat-tree as described above. That is because the edges near the root are emulated by many links to separate parents instead of a single high ...
In SPBM the shortest path trees are then used to populate forwarding tables for each participating node's individual B-MAC addresses and for group addresses; Group multicast trees are subtrees of the default shortest path tree formed by (source, group) pairing. Depending on the topology, several different equal-cost multi-path trees are ...
A tree topology is recommended for a large installation. KNX can link up to 57,375 devices using 16-bit addresses. The lowest eight bits provide up to 256 addresses within one line , which can consist of up to four segments , each having a maximum of 64 (TP1-64) devices, or up to 256 (TP1-256) devices.
