1. NVE Auto-discovery Protocol draft-gu-virt-edge-auto-discovery-00 Zhongyu Gu, Ting Ao, Chongfeng Xie, Vic Liu

2. Purpose Outline the NVE auto-discovery protocol to support VN automatic provisioning etc.

3. NVE Auto-discovery protocol Procedures VM preparation VM NVE NVA NVE Auto-discovery Initiation Packet NVE Auto-discovery Offer Packet NVE Auto-discovery Request Packet NVE Auto-discovery Session- confirmation Packet VM/VN authentication Create VRF etc Sync/w other NVE(s) VN Session NVE Auto-discovery Termination Packet VM/VN Information To/From other NVE(s) VN Session Stage Discovery stage

4. IANA considerations New type of Ether_Type for NVE auto- discovery – Discovery stage – Session stage

5. NVE auto-discovery protocol: Application VM live migration – Using VN itself as the migration sync transport NVE Corresponding VM src VM dst VM Step1: dst VM preparation Step2: dst VM Auto- discover NVE with Migration attribute Step3: after dst VM pass VN auth., dst NVE create VN context Step4: NVE floods VN info for dst VM Step4 Step5: src-dst NVE work as sync transport Step6: duplicate traffic supporting sync Step7: stop running after sync Step8: Begin running after sync Step9: NVE floods VM migrat- finish info

6. NVE auto-discovery protocol: Pro and Con Pros – Simplicity – Flexible (VM-NVE connection) – Potential Secure – VN Auto-provisioning – Supporting VM live migration Cons – New protocol/acceptability – VM support

7. Comparing with VDP TBD

8. Next Step… Comments collecting and further discussions Further detail information Comparison with VDP ……
