# Document Shepherd
# Technical Summary
This document specifies consumer and forwarder behavior as well as message
formats for a ping protocol for CCNx and NDN systems. It also describes the
specific differences of ICN-ping to IP-ICMP-based ping as well as security
ICN-ping is part of an instrumentation toolset for ICN. There is another
(https://datatracker.ietf.org/doc/draft-irtf-icnrg-icntraceroute/) that falls
into the same space.
# Document Quality
The document has been worked on since 2016 and has seen good feedback from
different ICN teams, especially with respect to compatibility to protocol
formats. The ICNRG last call has led to some corrections in this direction, and
the document is now considered ready for publication.
