    7575SSH to the {{{Experimenter}}} node, and start the consumer application
    7676     {{{

    7979The {{{Interest}}} packet travels the entire topology, leaving breadcrumbs. The {{{Data}}} packet follows the breadcrumbs back to the {{{consumer}}}, leaving cached versions of the content. This is call in-network caching and it is one of the most important features in {{{Information Centric Networking (ICN)}}}
     
    8181SSH to the {{{PI}}} node and start the consumer application
    8282     {{{

    8585This time your {{{PI}}} node gets the content back, but nothing happens on the {{{Custodian}}} because the requested content is cached in the {{{Campus Router}}} node.[[br]]
    86 Note that this time the {{{Data}}} was retrieved much faster.[[br]]

    8787You can repeat the experiment with different namespaces

    9191This time you see that the {{{Interest}}} request is served by the {{{Custodian}}}.
