Hi ALTO,

In my email announcing the impending closure of ALTO, I mentioned a number
of potential outlets for future work. I neglected to mention PCE
<https://datatracker.ietf.org/wg/pce/about/>, which to me seems to covering
a similar problem area. If they haven't already, I would encourage ALTO
practitioners to investigate PCE's activities and see where ALTO solves
their problems, or PCE work solves current ALTO problems.

Similarly, people working on PCE probably have issues with assembling a
topology database, and would probably be fruitful partners for those
working on assembling the ALTO database.

Thanks,
Martin
