Packet handling based on multiprocessor architecture configuration

Abstract:

Example methods are provided for a host to perform packet handling based on a microprocessor architecture configuration that includes a first node and a second node. One example method may comprise detecting, from a virtualized computing instance supported by the host, an egress packet for transmission to a destination via one of multiple physical network interface controllers (PNICs) of the host. The method may also comprise: identifying the first node assigned to the virtualized computing instance and selecting a first PNIC associated with the first node assigned to the virtualized computing instance. The multiple PNICs may include the first PNIC, and a second PNIC associated with the second node. The method may further comprise sending the egress packet to the destination via the first PNIC associated with the first node.
