Distributed methodology for peer-to-peer transmission of stateful packet flows

摘要

Techniques for enabling peer-to-peer transmission of stateful packet flows in a virtualized network environment are provided. In certain embodiments, a computer system receives a packet belonging to a stateful flow between a first virtual machine and a second virtual machine, accesses flow associating information (e.g., network address) from the packet, determines a second computer system comprising a state analysis owner for the stateful flow, using the flow associating information, and transmits the first packet to the second computer system.

主权项

1. A method comprising:
receiving, by a computer system, a first packet belonging to a stateful flow between a first virtual machine and a second virtual machine; accessing, by the computer system, flow associating information from the first packet, the flow associating information comprising a source network address and a destination network address; determining, by the computer system, a source host computer system using the source network address and a destination host computer system using the destination network address; selecting, by the computer system, from among the source host computer system and the destination host computer system, the host computer system with a lower network address as a state analysis owner for the stateful flow; and transmitting, by the computer system, the first packet to the selected host computer system.
