Abstract: The concepts and technologies disclosed herein are directed to a policy-driven homing service system that can receive, from a master service orchestrator, a demand specifying a service component to be used to provide, at least in part, a service. The system can receive, from a policy system, a homing constraint. The system can determine, for the demand, an initial set of all potential candidates. The system can apply the homing constraint to each potential candidate in the initial set of all potential candidates. The system can determine a resultant set of potential solutions that satisfy the homing constraint. The system can determine a best solution from the resultant set of potential solutions. The system can send the best solution to the master service orchestrator, which instantiates the demand based upon the best solution.

Abstract: A remote querying system and a service provider repository system functionally cooperate to efficiently store configuration information of one or more subscriber devices within the service provider repository system. The remote querying system receives the configuration information of the one or more subscriber devices from a service provider system. Thereafter, the remote querying system determines differences between this received configuration information and configuration information that is previously stored in the service provider repository system. Next, the remote querying system communicates these differences to the service provider repository system to allow the service provider repository system to update the previously stored configuration information.

Abstract: A software-defined network-based method and system for implementing a content distribution network. An application function, control function, and network entity resource of a CDN are added respectively to an application layer, control layer, and data forwarding layer of an SDN. When a request for a CDN application is received, the SDN application layer generates resource requirement and service scheduling information based on the request, and transmits a reservation request for a resource required by the CDN application to an SDN control layer. The SDN control layer allocates a resource required by the CDN application to combine network load balancing and path policies and to generate a content routing table for data transmission, generating and transmitting L2 and L3 forwarding tables to the SDN data forwarding layer. When it receives content distribution and content delivery requests, the SDN data forwarding layer executes a CDN service-related operation based on the forwarding tables.

Abstract: A method, system and computer program product for adaptive system monitoring. In one embodiment, the method comprises generating time-varying correlation graphs indicating correlations between a multitude of parameters of the system, and using the correlation graphs to identify monitoring logic for monitoring the system. In an embodiment, the correlation graphs are used to select a group of the parameters as monitoring parameters, and these monitoring parameters are dynamically changed. In one embodiment, the monitoring parameters form sets of monitoring parameters, and each set of monitoring parameters is used to monitor the system for an associated period of time. The lengths of these monitoring periods are changed based on the rate of change of the correlation graphs. In an embodiment, the rate at which the monitoring parameters are changed is itself changed based on the rate of change of the correlation graphs.
