#107: trickle-mcast: should multiple parameter sets be supported


Comment (by mcr@…):

 From: "Dijk, Esko" <esko.dijk@philips.com>

 > Any feedback from others in the WG on this?  Should we include support
 for selecting 1, 2, or more parameter sets?

 Having two parameter sets is useful to support two main uses of multicast
 in LLNs for the building control domain;

 1) Device/service discovery, such as mDNS and CoAP's /.well-known/core.
 Latency is less important here; avoiding high network load due to
 discovery traffic is also a goal if other more time-critical application
 are running at the same time.
 -> "slow" Trickle parameter set

 2) Building Control involving groups of devices
 Latency can be important (e.g. lighting control, or any device operation
 triggered by sensors or smartphones)
 -> "fast" Trickle parameter set
