It looks like the discoveryd protocol may not be working out for Apple and thus, it could be abandoned for both iOS 9 and OS X 10.11.
Recent analysis of the iOS 9 and OS X 10.11 El Capitan have shown that Apple has dropped the network protocol for the time being.
In both cases, mDNSResponder has been substituted in again, although the internal nature of the process makes it impossible to see whether it has changed at all since the build of OS X 10.10.4. The discovery protocol has been blamed for many networking and communication stability issues. One way Apple has achieved this is to get rid of discoveryd completely.
There is still a chance that discoveryd will return at a later date, perhaps in a later beta seed or future revisions of the platforms. For now though, users should expect to see the WiFi problems, seemingly solely caused by discoveryd misbehaving, go away.
Stay tuned for additional details as they become available.
