MECHANISM TO IMPLEMENT VCN NETWORK VIRTUALIZATION IN A RACK-BASED SWITCH

Abstract:

Aspects of the present application relate to systems, methods and non-transitory computer readable media for network virtualization in a rack-based switch. The method can include sending a communication from a first virtual machine ("VM") instantiated on a first host machine to a first network virtualization Top of Rack ("ToR") switch. The first network virtualization ToR can include a peripheral component interconnect express ("PCIe") switch coupled to a plurality of host-side Ethernet ports, a virtualization device communicatingly coupled to the PCIe switch, which virtualization device can include a plurality of virtualization functions, and a switching ASIC coupled to the virtualization device and to a network-side Ethernet port. The method can include forming the communication into an Internet Protocol ("IP") packet with a first virtualization function of the virtualization device, and sending the IP packet to a second VM with the switching ASIC.
