ping any other node on the network that also has this CorDapp installed. +It demonstrates how to use Corda for messaging and passing data using a [flow](https://docs.r3.com/en/platform/corda/5.0-beta/developing/ledger/flows.html) without saving any states or using any contracts. + + +### Concepts +The `ping` utility is normally used to send a Send ICMP ECHO_REQUEST packet to network hosts. The idea being that the receiving host will echo the message back. +In this example the Ping flow will send the String "Ping" to a other member in the network. +The otherMember will correspondingly reply with "Pong". + +## Flows +You'll notice in our code we call these two classes ping and pong, the flow that sends the `"ping"`, and the flow that returns with a `"pong"`. + +Take a look at [Ping.java](./workflows/src/main/java/com/r3/developers/pingpong/workflows/Ping.java). +You'll notice that this flow does what we expect, which is to send an outbound ping, and expect to receive a pong. +If we receive a pong, then our flow is successful. +And of course we see a similar behavior in [Pong.java](./workflows/src/main/java/com/r3/developers/pingpong/workflows/Pong.java). +We expect to receive data from a counterparty that contains a ping, when we receive it, we respond with a pong. + +## Pre-Requisites +For development environment setup, please refer to: [Setup Guide](https://docs.r3.com/). + + +## Running the nodes +1.
