DX80 Network Basics

1.4 Tree Networks

In a tree network, the lowest level contains the nodes, referred to as leaves, whose only function is to transmit information

to the next highest level, the repeaters. The repeaters forward the data to the gateway.

In a mesh network, each node has some routing capabilities and maintains a network connection with at least two other

nodes. Most commonly, nodes within a mesh network maintain a link with all nodes within a specified distance.

In a star network, the gateway is in the center with radiating spokes outward to the nodes. Because of its shape, this

network is also referred to as a hub and spoke network.

Pros—New nodes added to the system do not slow down the entire network.

Cons—A repeater failure cuts off the nodes from the gateway; there are no

redundant communication links between network components; and chattering

brings down an entire network branch.

Pros—Information has multiple communication paths to the gateway; the

gateway can be positioned anywhere in the network; and chattering nodes are

removed from the network.

Cons—A new node adds multiple connections to the other nodes and

substantially slows the entire network.

Pros—The gateway maintains a communications connection with each node on a

separate communications path; if communication between one node and the

gateway fails, the rest of the network is unaffected; and chattering nodes are

removed from the network.

Cons—The network suffers from some speed decreases with each additional

node added; and a hub failure stops network communications.
