F5 announced their road map on supporting network visualization for Hyper-V.
F5® BIG-IP® hardware will support NVGRE gateway functionality beginning the first quarter of calendar year 2014. Integration with Windows Azure is currently available on F5’s BIG-IP solutions.
For me, this seems to be an important move as one of the mainstream vendor will be coming soon to support the network visualization initiatives. Lets hope for the best !
