17. Multi-Tenant Network Req’s
• Tenant wants to easily move VMs to/from the cloud
• Hoster wants to place VMs anywhere in the data center
• Both want: Easy Onboarding, Flexibility & Isolation

(10.1.1.1)
• Isolation Scenario
• Hoster wants to isolate all VMs from each other and allow internet connectivity
• #1 Customer Ask from hosters
• Community Scenario
• Hoster wants tenant VMs to interact with each other but not with other tenant VMs
• Requires a VLAN id for each “community” (limited scalability, only 4095 VLAN IDs)

Virtualization • Run multiple virtual networks on a physical network
• Run multiple virtual servers • Each virtual network has illusion it is running as a
on a physical server physical fabric
• Each VM has illusion it is
running as a physical server
20. Generic Routing Encapsulation
• 1 Provider Address per HOST (shared by all VMs on the host)
• Embed Tenant Network ID in the GRE header Key field

21. Address Rewrite
• Each VM IP (CA) is mapped to a unique Provider Address (PA)
• Regular TCP/IP packets on the wire

22. Address Virtualization Summary
GRE Encapsulation IP Rewrite
Deeper Multi-Tenancy Performance and
Integration Compatibility
Standards based – RFCs 2784 & 2890 No need to upgrade existing
NICs, existing switches, and
As few as one IP address per host existing network appliances
lowering burden on the switches
Immediately and incrementally
Full MAC headers and explicit Tenant
Network ID marking supports for traffic deployable today without
analysis, metering and control sacrificing performance
Any encapsulation will break stateless
offloads in the host server (LSO,
Checksum, RSC, RSS, VMQ)
