Or more specific:

DLR Control and Management Plane Components and Communications

NSX Routing Subsystem Components

NSX Components

In short (so you don't have too much work with a simple Google search):

For each DLR instance, there is a DLR Control VM, which is running on one of the ESXi hosts; the DLR Control VM has two communication channels:

  • VMCI channel to the NSX Manager via vsfwd, which is used for configuring the Control VM
  • VMCI channel to the DLR master Controller via netcpa, which is used to send the DLR’s routing table to the Controller
