[Nfd-dev] Interest lifetime for NFD command interests

Hi Alex,
Fair enough. But I just tested on the Raspberry Pi, and it takes NFD 1200 seconds to answer a prefix registration. For use on the Pi, we increased the command interest lifetime to 2000 milliseconds.

Hi Jeff,
I agree completely with this for prefix registration commands. I would say, there is no much value/reason to make the lifetime longer than, say, a second. Could be shorter, but on some extremely busy systems (like our Jenkins slave), even a simple registration may take some time.
For face creation, lifetime should be longer that 4 seconds since it can take some time to create some tunnels (e.g., TCP). We even have a redmine issue for that (http://redmine.named-data.net/issues/1455)

For a command interest to NFD/NRD, is there a recommended InterestLifetime (used as a timeout)? Since it goes to the local host, can it safely be shorter than 4000 milliseconds?
Thank you,
