When extending networks to a remote VMware NSX-T Data Center, you can enable the HCX Mobility Optimized Networking service to route the network traffic based on the locality of the source and destination virtual machines.

Note: Mobility Optimized Networking is fully supported for VMware Cloud on AWS, and available for Early Adoption (EA) in other environments. For EA, enablement is available upon request and approval for NSX Enterprise Plus environments. For additional information about HCX Mobility Optimized Networking with VMware Cloud on AWS, see HCX Services for VMware Cloud on AWS.

This service ensures traffic from the local and remote data centers uses an optimal path to reach its destination, while all flows remain symmetric.

In the absence of Mobility Optimized Networking, all traffic from workloads on an extended network at the destination site is routed through the source environment router.

Network Extension with HCX Mobility Optimized Networking provides the following functionality:

  • Enable or disable Mobility Optimized Networking at the time of stretching a network

  • Enable or disable Mobility Optimized Networking for already extended networks

  • Enable or disable Mobility Optimized Networking on an individual VM basis for VMs residing on extended networks in the SDDC

  • Display which VMs are using Mobility Optimized Networking

  • When using HCX to vMotion a VM, preserve existing network connections while providing an option to enable Mobility Optimized Networking on that VM after migration
