Feature #3465

Updated by Junxiao Shi over 2 years ago

Currently, the [autoconfig stages include](http://named-data.net/doc/NFD/current/manpages/ndn-autoconfig.html#ndn-hub-discovery-procedure):

1. - discovery of hub within Ethernet or IP multicast domains
2. - discovery using DNS with domain suffixes obtained from DHCP
3. - discovery using pre-configured security credentials

The first stage needs to get extended to include mDNS / DNS-SD queries to discover locally available hub. Anecdotally, mDNS queries have higher chance to work than other protocols, even though they utilize the same IP multicast. This is a result of optimizations some hardware vendors did to allow mDNS to work while limiting multicast capabilities.
