[ovs-discuss] vswitch simulator for control plane scalability testing

[Zhou, Han]

Hi,

We want to setup an environment for large scale SDN simulation, to verify control plane scalability.
For example thousands of vswitches need to be simulated on top of limited number of physical machines (e.g. 10).
Each vswitch needs to support OVSDB and OpenFlow connections to controller. Even if installing OVS on VMs is not enough to achieve the scale.

An idea is not using real OVS but instead simulating multiple OVSDB+OpenFlow instances on a single VM.
Is this idea realistic based on Open vSwitch implementation? Any suggestions?

Best regards,
Han
