June 28, 2017 Workflow review
Chengli Wang and Lingli Deng from China Mobile presented VoLTE use case. They went through the work flow for service design, instantiation, auto healing/auto scaling and termination. 31 Participants joined the meeting and discussion.

Need to talk to OOM and MSB teams to see if we need those modules in the use case.
July 13, 2017 WAN Overlay Network
The meeting focused on how to build VXLAN overlay network between data centers (DCs) with EVPN protocol.
1. Discussed BGPVPN support by Openstack. VMWare and Wind River teams will go back and check if their VIMs support it. When new Intel lab is available for the community, a cross data center network can be set up to test the scenario.
2. Discussed the updated version of network diagram on wiki. Underlay network between two PEs is MPLS; and from DC-GW to PE is VLAN. VXLAN overlay is set up between two DC-GWs by EVPN. VTEP is on DC-GW. DC-GW is controlled by SDN local controller provided by vendor.
3. Inside DC from VM to DC-GW is VXLAN, it is set up and managed by Neutron.
4. Discussed the solution that SDN local controller provides some APIs to map DC-side VXLAN with WAN-side VXLAN on DC-GW. Chengli will provide the SDN local controller APIs which CMCC used in its lab to set up VXLAN tunnel with EVPN. Based on that information, we will provide a diagram on wiki to illustrate how the VXLAN mapping is done.
5. MultiVIM project proposed to handle DC-GW through SDN local controller and expose APIs for ONAP to set up VXLAN overlay between data centers via EVPN.
