Re: Purpose of HWvTEP implementation


Hi 1rving,

    Point no 2 is partially true.

    It is to enable vm workloads to have l2 communication with physical servers / sriov workloads behind the TOR devices within the same datacenter environment.

Subject: [ovsdb-dev] Purpose of HWvTEP implementation


Hi guys.


I got an idea to add a HWvTEP device into a "NetVirt with OpenStack" scenario, but so far I cannot see the advantages from this action.


So I start to consider the purpose of OVSDB HWvTEP scenario. The purpose is 1 or 2?


    1. The efficiency of overlay encapsulation, maybe VXLAN.


    2. "The idea behind hardware VTEPs is to create an overlay network that connects VMs and Physical Servers and make them think that they’re in the same L2 network even if they’re on opposite sides of the globe."


Any ideas would be appreciated.
