InterfaceHandler VmNetIntfHandler Searches for interfaces to look for Hello packets. VlanCommunication VlanCommunication Thread reading from an interface. HvncpSender HvncpSender Sends packets to the interface connected to the  corresponding HM. HvncpReceiver HvncpReceiver Receives packets from that interface connected to  the corresponding HM. Application  Management Engine  (AME) AppsMngt Manages application star, stop, and monitoring. AR AppReport Informs the KSYS controller about local application  details. Thread type Thread class name Description We also identified the kernel extension component and the  HAMonitoring.xml  configuration  file. To better understand the way these VMM daemon threads interact with each other and  with related components, we placed them all in the diagram in Figure 2-12. Threads responsible for communication with the HMs are grouped to simplify the diagram. Let  us first summarize what we know at this moment about the setup of communication with the  HMs.  Figure 2-12 VM Agent interaction with related components  Chapter 2.
