PACKET FORWARDING

摘要

A controller of a virtual switch system receives an uplink packet forwarded by a SDN switch hosted on a server from a VM (virtual machine) hosted on the server. The controller determines an outgoing interface from at least two uplink interfaces on the SDN switch respectively corresponding to aggregated member ports of a physical switch by using an aggregation algorithm according to the uplink packet. The controller generates a first flow table entry and sends the first flow table entry to the SDN switch, wherein the first flow table entry is to instruct the SDN switch to forward a received uplink packet to the physical switch through the outgoing interface.

1. A method for packet forwarding, comprising:
receiving, by a controller of a virtual switch system, an uplink packet forwarded by a virtual SDN (Software Defined Networking) switch hosted on a server; said uplink packet originating from a virtual machine (VM) hosted on said server; determining, by the controller, an outgoing interface from at least two uplink interfaces on the SDN switch respectively corresponding to aggregated member ports of a physical switch by using an aggregation algorithm according to the uplink packet; and generating, by the controller, a first flow table entry, and sending the first flow table entry to the SDN switch, wherein the first flow table entry is to instruct the SDN switch to forward a received uplink packet to the physical switch through the outgoing interface.
