Detailed Description

Guessing home router based on the default identity name.

This stage assumes that user has configured default certificate using http://ndncert.named-data.net/

• Request

  The end host loads the default user identity (eg. /ndn/edu/ucla/cs/afanasev), and converts it to DNS format.

  The end host sends a DNS query for an SRV record of name _ndn._udp. + user identity in DNS format + _homehub._auto-conf.named-data.net. For example:

  _ndn._udp.afanasev.cs.ucla.edu.ndn._homehub._autoconf.named-data.net
  

• Response

  The DNS server should answer with an SRV record that contains the hostname and UDP port number of the home NDN router of this user's site.
