Requirements on NVE and introduction of VDP Yingjie Gu IETF84/NVO3

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

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 IETF84/NVO3

A potential mechanism ---- Brief Introduction of VDP VDP = VSI Discovery & Configuration Protocol The picture is copied from “bg-sharma-evb-VSI-discovery-0110-v01” IETF84/NVO3

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 IETF84/NVO3

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. IETF84/NVO3
