When Virtual Meets Physical at the Edge: A Field Study on Datacenters' Virtual Traffic

摘要: The wide deployment of virtualization in datacenters catalyzes the emergence virtual traffic that delivers network demands between physical and machines hosting clients' services. Virtual presents new opportunities for reducing demands, as well challenges increasing management complexity. Given plethora prior art on technologies datacenters, surprisingly little is still known about such traffic, its dependence machines. This paper provides a multi-faceted analysis patterns impacts multiplexing onto network, particularly from perspective edge. We use large collection field data production number diversified services multiple enterprise tenants. Our first focus uncovering temporal spatial characteristics i.e., demand growth communication patterns, with special attention paid to migrating second characterizing effect terms locality, load heterogeneity, dependency CPU processing power at edges network. Last but not least, we conduct mirroring service QoS, defined by unavailability induced related issues, e.g., loads. qualitatively quantitatively discuss implications capacity planning virtualized networks datacenters.
