I have been assigned as Routing Directorate QA reviewer for this document.
The following web page contains a briefing on the QA process.
https://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDirDocQa
The document is clear and concise and succinctly describes a proposed
standardised SPF backoff algorithm. This seems a useful step forward.
The algorithm is not overly complex.
While suggested values for the various parameters are given, what is not
clear to me is whether the intention is that these (or at least an
agreed set) of these values are intended to be standardised as well as
the algorithm. It would seem that different values might be suitable for
different networks, but presumably the intention is that all the routers
in a particular network SHOULD have the same values. Some discussion of
this would be helpful.
I assume that "rib computation time" is the time that a RIB computation
is to be (or was) STARTED? Obviously the FIB will not be updated for
some time after this, in some cases for quite a long time after this!
Does this delay need to be taken into account? I appreciate that in many
cases it is difficult to ascertain reliably exactly when a FIB update
has been completed.
In reading the document I spotted the following nits.
Intro para 3
"some back-off algorithm have"
presumably algorithms
and
"to enforce that all routers
triggers their SPF
presumably trigger
Bottom of page 3
"SPF_DELAY back to INITAL_WAIT. e.g. 5 seconds."
obviously should be INITIAL_WAIT
4. Principle of SPG algorithm
3rd para
"and the while
waiting for its stability,"
"and while waiting" would be better.
6 Impact on micro-loops
"FIB are installed"
The FIB is installed
or
FIBs are installed
