Abstract:
The familiar toolset of VPN and IP/MPLS protocols defined in IETF
has been discussed as a good starting point for addressing several
of the problems described in the NVO3 problem statement and
requirements drafts. However, there is a significant gap between the
VPN technologies and the scale and complexity required when the NVEs
are running in server hypervisors.
This draft proposes a solution that bridges the gap between the
concepts familiar to the data center IT community with some of the
best concepts developed by the networking industry.
The proposed solution is based on the understanding that in a cloud
environment NVEs may reside in end-devices that should not be
burdened with the complexities of control plane protocols. The
complex control plane functionalities are decoupled from the
forwarding plane to minimize the required NVE processing,
recognizing that major hypervisor distributions already employ
Openflow to address this issue.
The solution also defines the mechanisms for scaling data center
network control horizontally and interoperates seamlessly with
existing L2 and L3 VPN devices.
