摘要： Methods and apparatus are disclosed for signalling congestion being caused by data items such as packets, received at a network element such as a router, in a communications network such as the Internet, or being caused by items otherwise requiring service or capacity from a shared resource. Preferred embodiments of the method involve identifying whether or not received data items received at a network element are capable of carrying congestion indications such as ECN marks, and for those that are capable, assigning congestion indications to the data items in dependence on a queue length characterisation based on a substantially current, instantaneous measurement of the length of the queue, whereas for those that are not capable, a sanction such as dropping may be applied in dependence on a different queue length characterisation based on a weighted moving average of current, recent, and less recent measurements of the length of the queue.

摘要： A method of maintaining a plurality of infrastructure components as part of a transmission network for a utility service in a defined geographic region having associated environmental characteristics, wherein each infrastructure component is deployed at a location in the region having associated one or more location characteristics and is of a component type having associated one or more infrastructure characteristics. The method including for each infrastructure component, executing a classifier based on one or more of the infrastructure characteristics, the location characteristics, and the environmental characteristics to forecast a measure of susceptibility of the infrastructure component to one or more operational impediments. The method further includes selecting an infrastructure component based on the forecast susceptibilities and deploying one or more mitigation measures for the selected infrastructure component to mitigate one or more operational impediments to which the selected component is determined to be susceptible based on the forecast susceptibilities.

摘要： A data management process determines, from user-implemented provisional reservations (400) for data processing resources, a projected total capacity requirement for each said data processing resource, by maintaining a record (9, 90, 91) recording previous such reservations made by each user and comparing each reservations with records (87, 88, 89) of the actual resources used, to provide an estimate of resources required to meet the projected capacity requirement, and to provide data for a demand management processor (2), which control associated configurable data processing equipment (1) to provide the resources required to meet the estimated capacity required. The process takes account of over- and under-ordering of capacity by comparing each reservation (400) with the use actually made (600), and includes a record (10) of ad-hoc (unreserved) usage.

摘要： A method of defining a deployment specification for one or more infrastructure components as part of a transmission network for a utility service in a defined geographic region includes receiving a deployment specification for each of a plurality of deployment options, each received specification including a location and type of one or more infrastructure components for deployment in the region, each type of infrastructure component having associated infrastructure characteristics, and each location having associated location characteristics. The method further includes receiving environmental characteristics for the region; executing a classifier, for each deployment specification, based on one or more of the infrastructure characteristics, the location characteristics, and the environmental characteristics to forecast a measure of susceptibility of infrastructure deployed in accordance with the specification to one or more operational impediments of the infrastructure in use; and selecting a deployment specification based on the forecast susceptibilities.

摘要： A method for deploying virtualized network functions (VNFs) as virtualized implementations of logical network devices in a virtualized computing environment for providing network services, the method including determining a VNF deployment plan including a specification, for each point in time over a planning period, of zero or more VNF instances to be released at the point in time and zero or more VNF instances to be deployed at the point in time, wherein the deployment plan is determined by an optimization function based on: a constraint on a number of VNFs in all states of undeployed, being deployed, deployed and being release; constraints based on a demand for VNFs defined by characteristics of the VNFs and the virtualized computing environment; and constraints based on a capacity of the virtualized computing environment to accommodate a resource consumption of the VNFs, and wherein the optimization function is configured to minimize one or more of: a number of VNFs in a deployed state; and a resource cost of deploying and releasing VNFs; and executing the VNF deployment plan to deploy VNFs for the virtualized computing environment.
