2. Basic Functionality Reqs on NVE
NVE to VNI Registration
VNI to Multicast Addr Mapping
Synchronization
Optional : QoS, DHCP snooping, ACL
Per-VN state
VM awareness
Connectivity Notification
Inner Address Notification
Local Tag Feedback
IETF84/NVO3

3. Architecture
Able to : NVE to VNI Registration, VNI to Multicast Addr Mapping, Synchronization
Able to : Connectivity Notification, Inner Address Notification, and Local Tag Feedback
Advantages : Distributed burden from single controller/database, real-time awareness of VMs/servers

4. A potential mechanism ---- Brief Introduction of VDP
VDP = VSI Discovery & Configuration Protocol

5. Notification or feedback of MAC/VLAN/Group ID
Pre-assoc
Associate
De-Associate
VSI is migrating
Or suspending
Notification or feedback of MAC/VLAN/Group ID
Find the VSI’s property in Profile database
GroupID identifies a VLAN
Identifier of VSI;
Constant during migration
Global unique

6. Reusing is better than invention. VDP is just a possible one.
There exists more than one way to fulfill the assistance to NVE, and even there is more than one existing protocol that we can consider.
Reusing is better than invention.
VDP is just a possible one.
