Concepts and technologies disclosed herein are directed to virtual zones for Open Systems Interconnection ('OSI') communication model layers 4-7 services in a cloud computing system. According to one aspect of the concepts and technologies disclosed herein, a cloud computing system can include a hardware resource and a virtual zone. The virtual zone can include a virtual network function ('VNF') that is executable by the hardware resource. The VNF can support a service that operates within one of layers 4-7 of the OSI communication model. A computing system can detect new subscribers to the service within the virtual zone. The computing system also can determine that a capacity constraint exists within the virtual zone as a result of the new subscribers. The computing system also can home the new subscribers to the further virtual zone so that the further VNF can provide the service to the new subscribers.

Virtual zones for open systems interconnection layer 4 through layer 7 services in a cloud computing system

According to one aspect disclosed herein, a service centric virtual network function architecture can be used for development and deployment of services in a cloud computing system. The cloud computing system can include a plurality of compute resources and a plurality of memory resources. A portion of the plurality of memory resources can include virtual machine monitor instructions. The virtual machine monitor instructions can be executed by a first portion of the plurality of compute resources to perform operations. In particular, the virtual machine monitor instructions can be executed by the first portion of the plurality of compute resources to instantiate a virtual network function to be executed by a second portion of the plurality of compute resources. The virtual network function can include at least a portion of a decomposition of a physical network function that supports at least a portion of a telecommunications service.

Service centric virtual network function architecture for development and deployment of open systems interconnection communication model layer 4 through layer 7 services in a cloud computing system

Concepts and technologies disclosed herein are directed to a service compiler component and service controller for Open Systems Interconnection ('OSI') communication model layer 4 through layer 7 services in a cloud computing system. According to one aspect of the concepts and technologies disclosed herein, the service compiler component can receive compiler data associated with a new service. The service compiler component also can analyze the compiler data at least to determine at least one virtual network function ('VNF') to be used to instantiate the new service. The service compiler also can generate a template for the new service.

Service compiler component and service controller for open systems interconnection layer 4 through layer 7 services in a cloud computing system

According to one aspect of the concepts and technologies disclosed herein, a cloud computing system can include a hardware resource and a Network Platform as a Service ('NPaaS') layer. The NPaaS layer can expose a cloud service for use by a service that operates within at least one of layer 4 through layer 7 of the Open Systems Interconnection ('OSI') communication model. The cloud service can include a database service, an application container service, a resource broker service, a load balancer service, a domain name system (&#x201c;DNS&#x201d;) service, a state persistence service, a probe service, or a combination thereof. The NPaaS also can receive a request for the cloud service, and in response to the request, can provide the cloud service.

Network platform as a service layer for open systems interconnection communication model layer 4 through layer 7 services

A method for maintaining signaling history of application servers to be invoked and applications to be provided in a VoIP network. In one illustrative embodiment, the signaling history of application servers that have been invoked and/or applications that have been processed is inserted into a message header by each application server in the network in turn as applications are processed. These headers are then carried in the message traffic between the SB, CCE and AS's in order to maintain a record of these invocations/processing. The SB may illustratively refer to these messages in determining the order in which applications are to be processed as well as to determine when all services have been processed. In another illustrative embodiment, this signaling history may illustratively be carried in SIP VIA headers.

Method for maintaining signaling history in a Voice-over-Internet-Protocol (VoIP) network

A method and apparatus for identifying and prioritizing applications and application servers in a Voice over IP network is disclosed. In a first embodiment, elements of signaling information are extracted from a call and are mapped to parameters associated with the call. These mapped parameters are then used by a service broker in a VoIP network to identify one or more application servers adapted to process the values of the respective parameter. The service broker may illustratively identify the application servers by a pointer to permit flexible reassignment of processing of a given parameter. The matched pointer/parameter combinations are then mapped to a precedence index. Then, according to this precedence index, the aforementioned pointers are mapped to specific addresses of application servers and the elements of signaling information are forwarded to those addresses for processing of applications.
