A method is provided. The method includes the steps of: generating a model of an information technology process, wherein the process comprises a plurality of process steps and wherein the model identifies resources associated with the process; identifying dependencies on the resources for at least one process step or the plurality of process steps; perturbing the model; assessing an impact of the perturbation on the model; and reducing the impact of the perturbation on the model by utilizing at least one remedial action.

A method of generating an annotated network topology of a network is described. The method includes determining available bandwidth “B” of a network on a network path connecting a pair of endpoints by performing Transfer Control Protocol (TCP) flows between the pair of endpoints, the network having a plurality of network paths, identifying a bottleneck link in the network path, and annotating all edges in a network path, wherein available bandwidth annotation of links inside the network is determined using end-to-end network measurements. A system for generating the annotated network topology of a network is also described.
摘要:
Managing application performance on a network. A network graph is generated from a set of application endpoints on the network. The network graph is annotated by associating one or more of the application endpoints with at least one of a corresponding latency annotation or a corresponding available bandwidth annotation. An end to end plan is formulated from the annotated network graph, wherein the plan maps one or more application requirements onto the plurality of paths in accordance with one or more end to end control adjustments including at least one of a server selection adjustment, an internet service provider (ISP) selector, or an overlay routing adjustment.

A system and method for scalable status change detection in a network of nodes includes embedding node coordinate positions into a virtual map environment. A cluster of nodes are represented with a representative node to form a hierarchy of nodes and clusters where changes in a status of the representative node imply a status change in the nodes of the cluster. By selectively monitoring the representative nodes for the changes in status, the representative nodes create a capability for scalable monitoring of the network.

A method of generating an annotated network topology of a network is described. The method includes; deriving a network topology by performing a route tracing utility between each pair of endpoints to determine the route taken by packets; initially annotating each network path with an initial value; determining the available bandwidth of a path connecting a pair of endpoints by performing Transfer Control Protocol (TCP) flows between the pair of endpoints; identifying a bottleneck link in the network path, and annotating all edges to generate an annotated network topology wherein available bandwidth annotation of links inside the network is determined using end-to-end network measurements.
