2.3.1.1 Centralized Network Topology
return to Network Topology Taxonomy
The centralized network topology (usually associated with mainframes) has a very large centralized server node that all other nodes connect to. It provides most of the services such as data storage, processing, backups, and computational power for the other nodes. It is possible to implement a “text/html2022-05-27T20:18:39-0400Anonymous (anonymous@undisclosed.example.com)2.3.1.2 Decentralized Network Topology

2.3.1.2 Decentralized Network Topology
return to Network Topology Taxonomy
In a decentralized network topology, there are several “central” nodes, each providing redundancy and failover capabilities for the other. Often, each of the centralized nodes are geographically distributed (i.e., North American, Europe, Southeast Asia, etc.).text/html2021-10-05T18:32:51-0400Anonymous (anonymous@undisclosed.example.com)2.3.1.3 Distributed Network Topology

2.3.1.3 Distributed Network Topology
return to Network Topology Taxonomy
In the distributed network topology, all nodes are equal peers within the system, with each acting as a redundant copy of other nodes. This provides for extremely high fault tolerance, tied to the number of nodes. The more nodes, the greater the tolerance to faults. Since each node is an equal peer, there is no single point of failure and there is no one master copy of the data. As a result, thetext/html2022-03-15T17:34:48-0400Anonymous (anonymous@undisclosed.example.com)2.3.1.4 Relevant Networking Standards

2.3.1 Network Topology Taxonomy
return to Taxonomic Views
Probably one of the most significant differences between DIDO architectures and other architectures is the simple, but powerful, topology of the network of nodes it uses to connect peers. DIDOs rely primarily on a distributed rather than a decentralized or centralized topology. Each
