Hello, guys!
Does anybody know about FOSS alternatives to this "virtual
networking" layer these guys are proposing?
Isn't http://wiki.openstack.org/Quantum relevant? IIRC, it was a
Nicira employee who wrote/leads Quantum to 'provide "network
connectivity as a service" between interface devices (e.g., vNICs)'. I
wonder if that's at the core of their product now?
Dan Wendlandt of Nicira presented this at the oVirt workshop last
November:

OpenStack Quantum currently has basic "virtual networking" capabilities.
Its Open vSwitch plugin and agent map tenant networks to VLANs at the
compute nodes, but depend on standard VLAN layer 2 switching to move
data between compute nodes (and services such as VPNs, firewalls, etc.).
I believe Nicira's product avoids the limitations of VLANs (i.e. only
~4K VLAN tags) and provides additional capabilities.
An open source project that also plugs into Quantum and may be worth
investigating is http://www.osrg.net/ryu/overview.html.
