Subject Big Switch & Floodlight
Date Thu, 25 Jul 2013 15:17:50 GMT
Hi All,

Just wondering if the Bigswitch integration for CS requires the Big Virtual
Switch component or whether this is just a complimentary aspect? I ask this
as I’m wondering if the future holds the possibility of using the
Floodlight controller in CS with third party Floodlight compatible ‘apps’
but without having to purchase both the commercial Big Virtual Switch and
the Big Network Controller. Does the plugin talk to the controller directly
or does it have to talk to the BVS for instance? I’m not averse to paying
for good software but from the prices I’ve seen for BVS and BNC I simply
can’t justify the investment at the moment.

I understand that there is on-going work with this from both a GSOC
participant (“tuna”) as well as Big Switch Networks themselves (Kanzhe
Jiang) but I can’t for the life of me work out what’s been done, what’s
going to be done and what might work already. It get the impression that
the current plugins don’t work with Floodlight but this is only due to the
fact that the Floodlight API were not finalised in time for the 4.1 code.
Does anyone have an insight into what might be possible in 4.2 or even 4.3
with regards to Floodlight, in particular the use of Floodlight to create
non-VLAN/GRE/STT isolation (they call them Virtual Network Segments) – not
too sure if this would work for broadcast or multicast isolation though.
Looking at code is unfortunately quite foreign to me – I’m a networking guy
at heart.

Many thanks,
