    摘要: A method is implemented in a network element to generate quality of experience (QoE) metrics for hypertext transfer protocol (HTTP) sessions over a network between a user device and an HTTP server. The QoE metrics are based on detecting premature termination of a download process that indicate low QoE. This QoE metric data can then be utilized by network administrators or service providers to adjust network characteristics to improve the QoE or to offer changes in services to a customer that would improve the QoE.

    摘要: A network topology design system to determine placement of a set of controllers within a network with a split architecture, the placement of the set of controllers selected to minimize disruption of the split architecture network caused by a link failure, a switch failure or a connectivity loss between the set of controllers and the data plane components. The system performs a method including graphing a topology of the split architecture network, determining a set of clusters of nodes within the graph by applying an agglomerative clustering process or a partitive clustering process, determining, a centroid for each cluster in the set of clusters, assigning one of the set of controllers to each network element corresponding to a determined centroid in the graph, and assigning each controller to control a set of network elements corresponding to a cluster in the graph.
