Abstract: The present disclosure involves systems and methods for (a) model distributed applications for multi-cloud deployments, (b) derive, by way of policy, executable orchestrator descriptors, (c) model underlying (cloud) services (private, public, server-less and virtual-private) as distributed applications themselves, (d) dynamically create such cloud services if these are unavailable for the distributed application, (e) manage those resources equivalent to the way distributed applications are managed; and (f) present how these techniques are stackable. As applications may be built on top of cloud services, which themselves can be built on top of other cloud services (e.g., virtual private clouds on public cloud, etc.) even cloud services themselves may be considered applications in their own right, thus supporting putting cloud services on top of other cloud services.

Abstract: The present disclosure involves systems and methods for compiling abstract application and associated service models into deployable descriptors under control of a series of policies, maintaining and enforcing dependencies between policies and applications/services, and deploying policies as regularly managed policy applications themselves. In particular, an orchestration system includes one or more policy applications that are executed to apply policies to a deployable application or service in a computing environment. In general, the orchestration system operates to create one or more solution models for execution of an application on one or more computing environments (such as one or more cloud computing environments) based on a received request for deployment.

Abstract: For enriching presence statuses of users in a contact list with call routing rules associated with said users, the presence statuses indicating an availability of said users, called contact users, for communication and being delivered by a presence server (PS) to an application (UCA) implemented in a communication device (CD) owned by a user, called application user, the presence server: sends a request to a call server (CS) managing call routing rules of said contact users, the request containing identifiers (IdCU) of said contact users, receives a response from the call server, the response containing routing statuses (RS) of said contact users, the call server having determined call routing rules (RR) stored respectively in correspondence with the identifiers (IdCU) and having interpreted the call routing rules (RR) to create a routing status for each contact user, and sends a message to the communication device (CD), the message containing the routing status for each contact user, in order that the applic

Abstract: A method and a resource broker are provided to control a conference session. The resource broker receives, from a conference controller, a message requesting to set up a conference communication for a participant. The message indicates whether a terminal of the participant supports selective forwarding. The resource broker verifies the availability of local selective forwarding and multipoint control resources. Based on the capabilities of the terminal and based on local resource availability, a reply is sent to the conference controller, indicating that the conference communication should be set up in selective forwarding or multipoint control mode, using local resources or resources of a network cloud. When a new participant is added or when a monitoring agent reports a change of availability of the local resources, the conference communication may be moved between the network cloud and the local resources, or change between selective forwarding and multipoint control modes.

Abstract: A method for allocating a video conferencing task within a computer network comprising a plurality of candidate processing devices, the method comprising: for each of the candidate processing devices: determining a topological score, the topological score being a function of at least one end-to-end delay between a pair of participating endpoints through the candidate processing device; for each candidate processing device within at least a subset of the candidate processing devices: determining an availability score, the availability score being a function of an available processing capacity of the candidate processing device; selecting a preferred processing device among the candidate processing devices as a function of the topological scores and of the availability scores, and allocating the video conferencing task to the preferred processing device.
