hb.unicast
The hb.unicast driver sends and receives using TCP unicast packets.
Basic Configuration
[hb#1]
type = unicast
Behavior with Basic Configuration
- The Rx thread listens on
0.0.0.0:10000 - The Tx thread sends to
<nodename>:10000
Advanced Configuration
A more precise definition allows specifying network interfaces, addresses, and ports for each node:
[hb#1]
type = unicast
intf@node1 = eth0
intf@node2 = eth2
addr@node1 = 1.2.3.4
addr@node2 = 1.2.3.5
port@node1 = 10001
port@node2 = 10002
timeout = 15s
Note the driver accepts to use the same port for every node:
port = 10001
Proper configuration of the hb.unicast driver ensures reliable communication between cluster nodes by leveraging TCP unicast.
