[AusNOG] Open Networking

Tue Jul 5 10:39:46 EST 2016

We've been running it for almost 18 months now in production and have done
a fair bit of work with a number of the vendors building OS platforms.

IMO the one to watch in the ISP/"Traditional Network" space is a product
called OCNOS by IP Infusion. It's a very Cisco like CLI with a range of
"carrier" technologies including MPLS, RSVP, LDP implemented. We have found
a couple of limitations with FRR, but still quite acceptable once tested.
We've also done a fair bit of interop testing with Juniper and Cisco and
are still running it in our labs on some S6000s and have had no major
issues. It also has a rudimentary HQOS implementation that we haven't
really drilled into yet.

The buffer discussion is something that we keep going back to with Dell.
I'm told it's a Broadcom architecture limitation at the moment, but there
are new chipsets due out later this year with larger packet buffers.

Thanks,
Andrew
