Is anyone using Neutron for high bandwidth workloads? (for sake of discussion let’s “high” = “50Gbps or greater”)

With routers being implemented as network namespaces within x86 servers it seems like Neutron networks would be pretty bandwidth constrained relative to “real” routers.

As we start migrating the physical connections on our physical routers from multiple of 10G to multiples of 100G, I’m wondering if Neutron has a clear roadmap towards networks where the bandwidth requirements exceed what an x86 box can do.

Is the thinking that x86 boxes will soon be capable of 100G and multi-100G throughput? Or does DVR take care of this by spreading the routing function over a large number of compute nodes so that we don’t need to channel multi-100G flows through single network nodes?

I’m mostly thinking about WAN connectivity here, video and big data applications moving huge amounts of traffic into and out of OpenStack based datacenters.


There are few internal implementations of the l3 plugin that are backed by dedicated hardware vs commodity+network namespaces.  Of those few, all are site specific (due to limited feature support and not likely to upstreamed).
