Our week in Hawaii was filled with lots of exciting and energetic discussions. Ray and I have a very thorough set of minutes to sort through and we will be posting these soon.
Our 30 minute time-slot for Routing Protocol Selection discussion turned
into 80 minutes, and continued in hallways, bars, and an ad-hoc meeting
slot the following day. This included technical discussion around a
partially unanticipated requirement for HNCP to support a stub network with
a gateway that doesn't have sufficient resources to run a routing protocol.
A technical solution was proposed and discussed ("proposal #1"), using the
attached slides. "Proposal #2" in the attached slide deck explored one way
to support "HNCP Fallback" plus a to-be-named "Routing Protocol" at the
same time in a Homenet. Consensus among participants in the discussion here
in Hawaii was that Proposal #1 should be adopted. There was strong
consensus that we should not support Fallback Routing at all in HNCP, hence
Proposal #2 was rejected.
As in the past, there was strong support for choosing a "MUST Implement"
routing protocol for all Homenet routers and that candidate routing
protocols must have an open source implementation available that can be
demonstrated to work in a Homenet alongside HNCP. There was also strong
support for setting a hard date, likely early 2015, to make a decision.
The two currently available routing protocols are IS-IS and Babel but at
this point there is no consensus on which is preferred, and other protocols
may emerge during the ongoing discussion. Margaret Wasserman has
volunteered to work on a draft comparing the two. Factors that might affect
the decision include (but are not limited to):
- compatibility with RFC 7368, including support for source/dest routing
- specification maturity
- open source implementation maturity, diversity, and portability
There'll be more to follow over the next few weeks as and Ray and I cement
our thoughts in consultation with our AD on how we'll make an objective
decision that will reflect WG consensus.
