  2. Goals For the Draft • Primary goal: define signaling between server and NVE (network virtualization edge) to allow simplified provisioning • Provision the server with all attributes (including networking) needed to instantiate a new VM … • … and server signals the NVE with the network attributes

  3. Goals • In order to give context to this signaling, we described in abstract but fairly detailed form the steps to create a new VM instance, to “hot” migrate, and to terminate a VM • Some took this as prescriptive (i.e., must happen as described), and weren’t sure that this belonged in the draft (or WG!) • Others were happy to see this written down

  4. Topics Discussed in -00 • VM provisioning • Network provisioning/signaling • Current Mode of Operation • Future Mode of Operation • Network parameters • Signaling choices for FMO • Technologies choices for network virtualization • Integration with network-wide control plane

  5. Updates 0001 • In the -01 version, we’ve tried to make it clear that the descriptive text around VM provisioning is just that: descriptive • expanded the sections dealing with this • added more detail around VM hot migration • Also tried to make it clearer that the NVE may reside on the server

  6. 0001 • We also expanded the sections describing what happens in the network in response to VM creation/migration/termination • The section describing how server2nve signaling interacts with the network-wide control plane has been removed in favor of a stub stating this needs to be done • We’ll produce a companion doc with that

  7. Planned future revisions • More focus on co-resident nve • Algorithm for tracking VN<->VID mapping • More details on network signaling for hot migration • Corner cases, timing issues, race conditions • Potential sources of traffic loss • At some point, syntactic details forvarious signaling protocols (XMPP, VDP, REST, …)

  8. Relationship with other drafts • May need some reqts added to draft-kreeger-nvo3-hypervisor-nve-cp • Perhaps a paragraph or two in framework draft • Lot of material recently added to draft-gu-nvo3-tes-nve-mechanism • Now there’s a fairly large overlap • draft-fw-nvo3-server2vcenter probably not directly related, as it is server to VM orch
