Open Stack

Hi Damon,

OpenContrail and juniper contrail products are exactly same. All our
development happens in open source.

We are agnostic to underlying hardware. We can support hardware GW. This
can be any router that supports BGP MPLS L3VPN/EVPN. We have tested with
juniper MX and CISCO ASR.

On Data plane, OpenContrail supports MPLSoGRE, MPLSoUDP, VxLAN, (choice of
Encapsulation is automatically decided by transmitter based on reciever)
Control plane we support is BGP L3VPN and EVPN.

You can view comparision of performance with open source OVS at following

I have tested OpenContrail with 882 hypervisor, The small number is because
I am not expert at tuning Open-stack. In Simulations we have tested unto
2000 hypervisors.

We would love to get feedback from you for the features that you think are
missing from OpenContrail.

Regards
-Harshad
