1. Introduction
Ascertaining 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
ascertain reachability of names is required.
This document proposes protocol mechanisms for a ping equivalent in
ICN (CCNx [RFC8609] and NDN [NDNTLV]) networks. A non-normative
appendix suggests useful properties for an ICN ping client
application, analogous to IP ping, that originates echo requests and
processes echo replies.
