## ping-pong
|
||
|
|
|
||
|
|
`ping-pong.go` implements a simulation network which contains nodes running a
|
||
|
|
simple "ping-pong" protocol where nodes send a ping message to all their
|
||
|
|
connected peers every 10s and receive pong messages in return.
|
||
|
|
|
||
|
|
To run the simulation, run `go run ping-pong.go` in one terminal to start the
|
||
|
|
simulation API and `./ping-pong.sh` in another to start and connect the nodes:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ go run ping-pong.go
|
||
|
|

|
||
|
|

|
||
|
|
```
|
||
|
|
|
||
|
|
```
|
||
|
|
$ ./ping-pong.sh

||
|
|
Use the `--adapter` flag to choose the adapter type:
|
||
|
|
|
||
|
|
```
|
||
|
|
$ go run ping-pong.go --adapter exec
|
||
|
|
