SPECIALIZING VIRTUAL NETWORK DEVICE PROCESSING TO BYPASS FORWARDING ELEMENTS FOR HIGH PACKET RATE APPLICATIONS

摘要

A method of optimizing network processing in a system comprising a physical host and a set of physical network interface controllers (PNICs) is provided. The physical host includes a forwarding element. The method includes determining that a set of conditions is satisfied to bypass the forwarding element for exchanging packets between a particular data compute node (DCN) and a particular PNIC. The set of conditions includes the particular DCN being the only DCN connected to the forwarding element and the particular PNIC being the only PNIC connected to the forwarding element. The method exchanges packets between the particular DCN and the particular PNIC bypassing the forwarding element. The method determines that at least one condition in said set of conditions is not satisfied. The method utilizes the forwarding element to exchange packets between the particular DCN and the particular PNIC.

1. A method of optimizing network processing in a system comprising a physical host and a set of physical network interface controllers (PNICs), the physical host comprising a forwarding element, the method comprising:
determining that a set of conditions is satisfied to bypass the forwarding element for exchanging packets between a particular data compute node (DCN) and a particular PNIC, the set of conditions comprising the particular DCN being the only DCN connected to the forwarding element and the particular PNIC being the only PNIC connected to the forwarding element; exchanging packets between the particular DCN and the particular PNIC bypassing the forwarding element when the set of conditions are satisfied; determining that at least one condition in said set of conditions is not satisfied; and utilizing the forwarding element to exchange packets between the particular DCN and the particular PNIC when at least one condition in said set of conditions is not satisfied.
