  • Publication number: 20230368099
    Abstract: The invention achieves an increase in speed and optimization of a cooperative operation plan creation work between a data center operator and a user. In an operation plan creation method in a data center, an operation plan server calculates a handling cost to handle a given consumption pattern of a DC user when an operation plan of a created workload (WL) is to be created or changed, and creates an operation plan optimization equation for maximizing or minimizing an index such as a cost including the handling cost. At this time, a solution of the operation plan optimization equation is obtained such that a consumption pattern obtained by changing a consumption pattern in a past response history of the user according to a certain rule is available at a handling cost to handle the changed consumption pattern, thereby creating an operation plan draft for the consumption pattern of the user and a device held by a data center operator.

  • Patent number: 10979361
    Abstract: Concepts and technologies are disclosed herein for creating cross-service chains of virtual network functions in a wide area network. A controller can receive a chain request from a requestor. The chain request can specify functionality that is to be included in a service chain. The functionality can include a first function and a second function. The controller can compute a route associated with the service chain. The route can specify a first site that hosts a first service that provides the first function and a second site that hosts a second service that provides the second function. A first virtual network function can be located at the first site and a second virtual network function can be located at the second site. The controller can configure edge devices and forwarding devices to various entities at the two sites to enable the cross-service virtual network function chain.
