User-space NIC (USNIC): USNIC is an ultra-low-latency solution for HPC and HPT applications over
Ethernet. The solution includes firmware, kernel driver, user-space driver, and Open Message Passing
Interface (MPI) support for Cisco VICs and provides OS bypass services directly to the application layer.

Cisco Data Center VM-FEX: Cisco Data Center VM-FEX technology extends fabric interconnect ports
directly to virtual machines, eliminating software-based switching in the hypervisor. Cisco Data Center VM-
FEX collapses virtual and physical networking infrastructure into a single infrastructure that is fully aware of
the virtual machines’ locations and networking policies (Figure 3). Cisco Data Center VM-FEX is
the virtual machines’ locations and networking policies (Figure 3). Cisco Data Center VM-FEX is
implemented by Cisco VICs with a prestandard implementation of IEEE 802.1BR Port Extender.
