RIOT/examples/ndn-ping

ndn-ping

This application demonstrates the usage of the package ndn-riot. This example basically enables the user to setup a ndn data server, and a ndn client that can request the data. Any board with a default netdev can be used to run this example.

Setting up for native

Create tap and tapbr devices using RIOT's tapsetup script before stating the application:

sudo ./RIOTDIR/dist/tools/tapsetup/tapsetup

Then run the application on 2 different terminals :

# on the first terminal
make PORT=tap0 term
# on the second terminal
make PORT=tap1 term

Usage

The user can run shell commands (type "help" to see the list). Only one command is relative to ndn : ndnping.

Start a server

ndnping server name_uri server_id

Replace name_uri by a ndn name (for example /test), and server_id by a number. server_id will be appended to the name of the data sent by the server. This can help when several servers are running using the same name_uri, but is not useful in our example.

A server will start and answer to any interest message matching the name.

Start a client

ndnping client name_uri max_count

Replace name_uri by a ndn name, and max_count by a number. max_count is the number of interest message that will be sent.

A client will start, send a first interest message and wait for a data message. Once data is received or timeout is reached, the client can send the next interest message, or stop when the last interest have been sent.
