•
Routers are measurement or telecommunications devices that route packets
to other linked routers or leaf nodes.
•
Routers can be branch routers. Branch routers only know as neighbors
central routers, routers in route to central routers, and routers one level
outward in the network.
•
Routers can be central routers. Central routers know the entire network. A
PC running LoggerNet is typically a central router.
•
Routers can be router-capable dataloggers or communications devices.
The CR200(X) is always a leaf node. It cannot be configured as a router. The
network shown in
FIGURE. PakBus Network Addressing
(p. 134) contains 6
routers and 8 leaf nodes.
Figure 49: PakBus Network Addressing.
LoggerNet is configured by default as a router and can route datalogger to
datalogger communications.
14.3 Router and Leaf Node Configuration
Consult
APPENDIX. Router and Leaf Node Hardware
(Appendix p. 33) for a
table of available PakBus® leaf node and router devices.
14.4 Linking Nodes: Neighbor Discovery
To form a network,
nodes
must establish
links
with
neighbors
(adjacent nodes).
Links
are established through a process called
discovery
.
Discovery
occurs when
nodes
exchange
hellos
. A hello exchange occurs during a
hello-message
between two nodes.
