Virtual Networks/Overlays

Problem Being Solved: Hard to extend L2 net domains & migrate workload

  • Suboptimal asset utilization & availability due to physical rack limited cluster scope(s)
  • Workload migration is time consuming & complex

Open Networking Components:

  • Open SDN Controllers, OVSDB, multiple tunneling protocol options e.g., VxLAN, GENEVE, open provisioning APIs, neutron, etc.
  • Create an open approach to virtual networking/Overlays
  • Terminate endpoints on hypervisors + ToR
  • Integrated tunneled traffic management

Gap: Lack of standards and/or a standard. VLAN stretching not a solution

Benefits: Extend L2 domains & decouple net config policies independent of underlay

  • Business unit self-service delivery
  • Lower OpEx cost
