                 ICN Traceroute Protocol Specification
                draft-mastorakis-icnrg-icntraceroute-03

Abstract

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

1.  Introduction

   In TCP/IP, routing and forwarding are based on IP addresses.  To
   ascertain the route to an IP address and to measure the transit
   delays, the traceroute utility is commonly used.  In ICN, routing and
   forwarding are based on name prefixes.  To this end, the problem of
   ascertaining the characteristics (i.e., transit forwarders and
   delays) of at least one of the available routes to a name prefix is a
   fundamendal requirement for instumentation and network management.

   This document describes protocol mechanisms for a traceroute
   equivalent in ICN networks based on CCN or NDN.  This document
   contains a non-normative appendix section suggesting useful
   properties for an ICN traceroute client application that originates
   traceroute requests and processes traceroute replies.

1.1.  Requirements Language
