Virtual Ethernet Module (VEM), a software switch embedded in the hypervisor
Virtual Supervisor Module (VSM), which manages networking policies and quality of service for virtual machines in concert with the VEM

The Cisco Nexus 1000V Switch can optimize the use of Layer 4-7 services in a virtual machine environment through Cisco vPath architecture services.

Cisco vPath technology is aware of all Layer 4-7 policies associated with individual virtual machines. Once the data packets of a specific virtual machine have been identified and policies applied, the remaining data packets flow directly to the virtual machines.
