ndnping and ndnpingserver

Introduction

ndnping and ndnpingserver are reachability testing tools for Named Data Networking. They test the reachability between two nodes. The client sends an Interest intended for a node running ndnpingserver. The ping server then sends Data in response. The client then calculates the roundtrip time for the Interest-Data exchange, or marks it as a timeout if the Data is not received within the timeout period.

Using the Client

The client can be invoked by calling ndnping with a name to ping. For example, to ping ndn:/edu/arizona, one would execute::

ndnping ndn:/edu/arizona

There are also a variety of options to control the behavior of the ping client. For example, to send only four pings to ndn:/edu/arizona, displaying a timestamp with each received Data or timeout, type::

ndnping -c 4 -t ndn:/edu/arizona

A list of the available options can be found with man ndnping.

Using the Server

The server can be invoked by calling ndnpingserver with a name to listen for pings to. For example, to listen for pings to ndn:/edu/arizona, one would execute::

ndnpingserver ndn:/edu/arizona

There are also a variety of options to control the behavior of the ping server. For example, to satisfy only 4 ping requests before exiting, execute the following::

ndnpingserver -p 4 ndn:/edu/arizona

A list of the available options can be found with man ndnpingserver.
