                      draft-irtf-icnrg-icnping-00

Abstract

   This document presents the design of an ICN Ping protocol.  It
   includes the operations both on the client and the forwarder side.

1.  Introduction

   Determining data plane reachability to a destination and taking
   coarse performance measurements of round trip time are fundamental
   facilities for network administration and troubleshooting.  In IP,
   where routing and forwarding are based on IP addresses, ICMP echo and
   ICMP echo response are the protocol mechanisms used for this purpose,
   generally exercised through the familiar ping utility.  In ICN, where
   routing and forwarding are based on name prefixes, the ability to
   determine reachability of names is required.

   This document proposes protocol mechanisms for a ping equivalent in
   ICN networks.  A non-normative appendix suggests useful properties
   for an ICN ping client application, analogous to IP ping, that
   originates echo requests and process echo replies.
