“In this case I am showing that there is flexability in how you use NIV in a virtual environment. The server administrator has decided one of the VM’s is really I/O intense and needs full blown VMDirectPath I/O, while other more common VM’s are just fine with standard hypervisor switching.” - Simple use cases for Network Interface Virtualization : INTERNETWORK EXPERT .ORG

network pieces
Incomplete thought [props to Hoff]…
I think that control plane and data/forwarding plane separation will end up a common feature of data center networks at scale, for cloud, etc. It’s a lesson from telcos.
The work of control plane software optimization is really a set of algorithmic route calculation (etc.) and distributed database problems that are better attacked outside the confines of network hardware, with general purpose machines.
The work of the data plane is more about capability optimization in asics, fpgas, etc. for latency, latency jitter, scaling, subscription rates, etc.
These two things have very different cycles and [I think] are better off not tied to one another.

analytics at network edges
Incomplete thought…
Much churn and anguish to remove the network limits to scaling virtualized environments has driven people to make the network “aware”, “intelligent”, and “smart” with a focus on virtualization, orchestration, etc.
In this, I think a useful idea has been lost—
The network should provide more intelligence. How about we embed serious awareness in the form of analytics capabilities into the network? Instead of discovering distributed/networked/cloud application hiccups, failures, overloads, etc., at the core and after the fact—I want to intercept and predict them at the edges where they start. There must be markers and patterns to requests, responses, session states, etc., that can be teased out and understood by the edge.. and once observed, passed on to correlators, orchestrators, management systems, etc.
Ultimately, I think there are decisions and actions that should be made/taken at the edge to head off certain kinds of problems before they manifest application-infrastructure-wide.
