US Patent 10320644 Traffic analyzer for isolated virtual networks

A traffic analyzer of a provider network identifies endpoint categories into which traffic directed to or from a first isolated virtual network of the provider network is to be classified. A first endpoint category includes an endpoint configured in a second isolated virtual network. Using packet-level metrics collected at virtualization management components of virtualization hosts, the traffic analyzer determines the amount of data transmitted between the first isolated virtual network and the various endpoint categories during selected time intervals. The traffic analyzer provides the categorized traffic amounts as input to a predictive model, and stores expected future traffic trends generated by the model.
